the old P-clips are too small for the thicker cables, so I just flattened them out like this and tied the harness to them

IMG_20211212_145411.jpg
IMG_20211212_152225.jpg

all secured and now battery reading a good 13.2v (loaded) 14.3v (unloaded) and 0.3v voltage drop from alternator to battery.
I think the battery fuse section of the fusebox still has abit of resistance there :unsure: but overall it's a big improvement

my centre punch broke few months ago, so I just machined a new piece on the lathe and it's working again, easy fix ?

IMG_20211216_201228.jpg


wednesday we had the last car meet of the year plus a secret santa gift round

IMG_20211215_194148.jpg


one of my good friends also surprised me with a nice drawing of kassandra :love:
luv it soo much, I added it to my wall of driving memories :cool:?

Good news, she passed her MOT with flying colours this year! ????
only advisory was a small nail on the rear tyre.

I'm used to seeing her initially fail on some minor things each year like worn joints, blown bulb, sticking seatbelt, rust, emissions, etc
I even ordered another spare set of spherical bearings just incase.

IMG_20211222_233912.jpg


but nope, everything was tip-top.

This makes a nice change for xmas ?

my friend with a Zafira was after some custom side window louvres

258325695_604335670718755_8792936523802052145_n.jpg


I traced the window shape from clear vinyl onto some perspex sheet (was suppose to order tougher polycarbonate but ended up with more brittle acrylic perspex sheet)

IMG_20211228_141845.jpg


trimmed into shape

IMG_20211228_152302.jpg


marked the louvres

IMG_20211229_003550.jpg


dremelled & cleaned the slots

IMG_20211230_203407.jpg
IMG_20211230_205604.jpg


clamped down each section and slotted a steel sheet under the slot

IMG_20211231_195807.jpg


after warming with a heatgun, I lift the steel plate at a set angle to evenly open the louvre shape

IMG_20211231_202756.jpg


I accidentally snapped a brittle section off whilst removing the clamps ? hopefully I can glue it

IMG_20211231_203838.jpg


vents all formed

IMG_20211231_211238.jpg


painted the backside black, leaving the other side glossy ?

the old brittle switch cover on my pillar drill was recently damaged

brought this independant 4-jaw chuck on ebay in the hope of centering the part for better accuracy

IMG_20220106_190851.jpg
IMG_20220106_200652.jpg


100mm dia 4 jaw independant chuck vs 3 jaw self-centering chuck

IMG_20220106_201153.jpg


the backplate has holes for the 3-stud & 4-stud pattern

IMG_20220106_201323_1.jpg
IMG_20220106_201329.jpg


unfortunately it turns out the jaws are not machined perfectly parallel to the spindle axis so this rod piece spins wonky with some serious run-out (rod axis doesn't follow the lathe spindle axis) :mad:
guess I'll have to figure later how to regrind the jaws straighter :rolleyes:

IMG_20220106_204902.jpg


swapped back to the original 3-jaw chuck and is perfectly straight. guess the cheap 4-jaw chuck skipped some quality control ?

was thinking the oyster sauce covered air filter was probably picking up some warm air behind the radiator so sometimes it feels pokier when the coolant or ambient air is cold vs other warmer times ?

IMG_20220106_122124.jpg


perhaps I could relocate the coolant tank and duct the filter over to the wing panel away from heat & rain much like on Dave Shaws blue turbo micra

IMG_20220106_122207.jpg


wiring loom may have to be rerouted from the bottom hole

IMG_20220106_122435.jpg


printed this adapter cone for the oyster sauce can to fit some cheap 100mm flexible ducting

IMG_20220106_235644.jpg
IMG_20220106_235616.jpg
IMG_20220106_235537.jpg


selected 100mm for larger area, less restriction to compensate for the turbulate tubing, plus it's only £2 for 4" duct compared to £30+ for the 2.5-2.75" duct

IMG_20220106_235545.jpg
IMG_20220107_000048.jpg
IMG_20220106_235959.jpg


shortened the excess length of the pipe too

IMG_20220107_195402.jpg


once ducting is finished it'll hopefully keep heat away from the intake

made a compact coolant tank from an old bottle of vinegar, alloy pipe and a bracket sandwiched between the cap (which as a bonus prevents the cap top from fully sealing, allowing air to leak past the thread gaps and venting the bottle. could drill extra holes if needed)

IMG_20220108_194527.jpg


fitted next to the radiator

IMG_20220108_202032.jpg


enlarged the hole in the wing section to slot the flexible ducting through

tday I chopped the larger hole for the ducting

IMG_20220109_121922.jpg


cusioned the sharp edge with some silicone tubing

IMG_20220109_122604.jpg


and fed the ducting through the hole

IMG_20220109_123456.jpg


also curled up this coolant bottle hose to keep the fluid level nearby the rad cap & reduce the air gap

IMG_20220109_125327.jpg


ducting taped onto the air filter shield/adapter

IMG_20220109_125336.jpg
IMG_20220109_125355.jpg


went for a test drive and oooh there is definately a noticeable difference, it feels more pokey throughout the revs with less flat spots whether the engine is hot or cold :cool:?

also fitted my m8s new window louvre onto their zafira, had to patiently bend it with the heatgun to follow the curvy glass. looks cool :cool:

designed this mount to fit my dremel onto the mini lathe to straighten the 4 jaw chuck

dremel mounting 1.jpg


3d printed the parts

IMG_20220113_230841.jpg
IMG_20220113_230623.jpg


bolted onto the slider

IMG_20220113_231040.jpg


dremel clamped on

IMG_20220113_231454.jpg
IMG_20220113_231515.jpg


used a loop of steel wire to preload the ends of each jaw under tension to simulate the clamping stresses

IMG_20220114_203925.jpg


marking the jaw face with red pen and then doing a light initial pass, you can clearly see just how warped these cheap jaws are to begin with.

this explains why they only held at the very tip of the jaws allowing the rod/material to move/wobble around inaccurately ?

IMG_20220114_212043.jpg


going through several very light passes with the dremel until all the red pen was machined off resulting in a straight surface aligned to the spindle axis

thank you John (y)

just numbered each jaw and then re-centered the chuck & rods and the run-out is a lot better.
it ain't perfect, there's a 5thou difference between near the chuck and 6 inch along the straight rod, but it'll do

:eek:
Didn't that hurt? i couldn't...
Couldn't you get the tubing to the driver side front grille? Could have gotten a little bit of a ram air effect as well.
hurt? not at all, I used the dremel cutting disc on it but it was a tight space to cut around (a hole cutter would've been better but didn't have the right size).

while the slightly +ve ram-air pressure from an open CAI funnel would've been nice at high speed it has a few issues such as:
- the oil catch cans are already behind the grills,
- heat from the manifold would cook/melt the intake ducting when stationary,
- rain/snow/water would flow directly into the filter

plumbing it over to the wing panel provides a consistantly cold & clean shielded air source with non of the drawbacks listed above

comparing the fitment of my old bumper vs a spare one

IMG_20220116_135534.jpg


the spare bumper mount looks more original than my old ones which seems to be a poor copy part with a missing captive nut & bracing.
the old mounts are also tapered by 1mm to fit deeper into the old bumper.
so the spare white bracket mounts with a broader front section won't fit onto my old bumper :unsure:

IMG_20220116_140910.jpg


ended up having to bend/squeeze the front parts more slimmer so that it can slot deeper into the bumper without fouling

IMG_20220117_192654.jpg


so slotting the old bumper onto the car in it's relaxed state, it's very clear to see that the drivers side of the bumper it about 10mm too wide, so bolting the sides to the wings would often deform it out of shape. I suspect this might be a cheap poor quality copy-part

IMG_20220116_144811 copy.jpg


whereas this spare bumper (probably original oem) fit's much closer to the wings

IMG_20220116_145023 copy.jpg


later in spring I'll repair & paint this spare bumper

repaired the bumper LED wiring which snapped off

IMG_20220123_130937.jpg
IMG_20220123_140250.jpg


this cheap PVC flexible hose for the intake kept breaking apart from repeated bending & engine vibration :rolleyes:

IMG_20220124_190644.jpg


so I brought some aluminium semi-flex hose from B&Q, but it has a 103mm ID/114mm OD whereas the 90mm hole I cut was suited for the PVC hose with 90mm ID / 105mm OD

IMG_20220124_191919.jpg


printed this 90mm - 103mm diameter adapter

IMG_20220124_234619.jpg


the inside bore is also smoother as a bonus

IMG_20220125_000008.jpg


now that fits snug, the semi-rigid duct holds it's shape much better and it's soo shiny :cool::cool:

IMG_20220125_001244.jpg
IMG_20220125_001301.jpg


after a few days commuting, it's held up much better than the PVC hose (y)

went for a drive through the usual route. unfortunately the stereo cockpit mic wasn't connected properly ? so I ended up editing the remaining muffled audio from the exhaust & foot well camera



and here's a datalog of it.



battery is running 13.3v compared to 13v previously.
MAF at low rpm is reading slightly lower than last yr, maybe dirty.
as a result the injectors are running slightly less duty.

removed the front wing

IMG_20220227_115452.jpg


removed the loom to reroute it from below

IMG_20220227_120951.jpg


chopped the hole larger for the 100mm ducting

IMG_20220227_122317.jpg
IMG_20220227_124858.jpg


spotted this rust hole which was letting water leak down into the a-pillar/sills, so I welded it up

IMG_20220227_124453.jpg
IMG_20220227_134827.jpg


but had a brief panic! when I saw smoke coming out the dashboard.
looked under the footwell behind the welding section and saw a little FIRE :eek:

as I ran to look for the garage extinguisher like a headless chicken I immediately decided to grab the nearby garden hose and soak the area.
the wiring may not like it but thankfully it worked ?
turned out it was just the damn seam-sealer catching fire as usual and the insulation/dash/wiring etc was fine.
that was scary.

printed this adapter plate for mounting the ducting to the wing panel

friends suzuki swift was having a lack of power issue recently, I tried testing every single possible mechanical/electrical issue with no faults found.

the only last resort is to check if it's starved of fuel, so I brought a fuel pressure tester

IMG_20220304_185958.jpg


tested it on kassandra first, she reads normal.
43.5psi when first primed on IGN,
34psi when pump stops after 4sec,
34psi with cold engine at idle,
constant 43.5psi at any rpm with fuel regulator vac line unplugged.

IMG_20220304_195534.jpg


ready to use the gauge on the Swift in few days

extended the scissor jack head slightly taller so that it can lift the car without damaging the LED strip taped along the sills

IMG_20220305_172311.jpg

the first intake ducting adapter didn't align well with the hole and the perpendicular angle was bending the ducting & putting stress on the pod filter

IMG_20220305_133952.jpg


so I designed it with a smooth bend pointing towards the filter and a thicker base to stop it flexing

lined up better

2022-04-02 Fit new BC BR coilovers

Time to install the new coilovers, but first I was curious to see her slammed low ?
so I removed the springs off the old BC V1 coilover

IMG_20220402_143931.jpg
IMG_20220402_152322.jpg
IMG_20220402_152546.jpg


sickk! ??
the rear was wayy too low with the tyres rubbing/ripping the bumper mount off whilst pushing her out the garage, had to remove the spacers to narrow the wheel track & allow it to move ?

looks neat but highly impractical & inconvenient for me ?

IMG_20220402_162158.jpg
IMG_20220402_162215.jpg


removed the old dampers

IMG_20220402_171258.jpg


swapped the rear top mounts over & matched the bottom mount length

IMG_20220402_172624.jpg


comparing the various lengths of BC rear springs ?

left: the original BC V1 rear coils are 3kg/mm and 200mm long

middle: new BC BR rear coils are also 3kg/mm but only 180mm long, which might cause issues with being uncaptive when you lower it too much considering the new dampers have a longer travel

right: the 5kg/mm rear coils I brought for the V1 is 190mm long, has a wide ball shape and is curved over

IMG_20220402_163231.jpg


the old spring perch screwed under the chassis was really seized, so decided to leave it on

IMG_20220402_171315.jpg


cleaned the threads and screwed the new BC BR adjuster rings onto the old perch and fitted the new dampers

IMG_20220402_174640.jpg


adjusted the bottom ring to set the rear bumpstop

IMG_20220402_180237.jpg


until the tyres clear the arch/bumper/exhaust etc by 5mm when you jack up the axle beam

IMG_20220402_180205.jpg


with the bumpstops set, I fit & adjust the rear springs till it sits at the target -50mm height

IMG_20220402_182704.jpg


now for the fronts, removed the springs, roughly set the bottom hub upright ring to match the old setup

IMG_20220402_203719.jpg


fit the unsprung strut & wheels

IMG_20220402_204456.jpg


lift the wheel up (lock to lock) with a jack underneath (wedging the brake pedal on helps to lock the wheels steady) until it hits bumpstop and lifts the body.
measure the gap and readjust the bottom ring till the tyre just clears the arch & chassis by 5mm

IMG_20220402_205053.jpg
IMG_20220402_210803.jpg
IMG_20220402_210957.jpg


IMG_20220402_211025.jpg


reinstall the front springs with zero preload

IMG_20220402_214251.jpg


the new front springs sit 15mm too high even at zero preload ?

IMG_20220402_221021.jpg


my options are either:
-raise the bottom hub ring without touching the bumpstops, which drops the height but tyres will hit the arch during bumpstop.
-raise the bottom hub ring (to drop the height) and increase the bumpstops with washers on top to prevent tyres rubbing the arch but at the cost of reduced droop travel.
-fit helper springs to drop it by 35mm but retain the same bumpstop, bottom ring position & full suspension travel, which is my ideal choice

IMG_20220403_121210.jpg


I first fitted the helper springs & set the adjuster ring at the lowest relaxed position to see where it sits.
it now sat 20mm below target

IMG_20220403_122240.jpg


so now I can raise the adjuster ring to increase preload, squishing the helper spring and raising the height back up to my target -50mm lowered height

fitted the protective coilover covers

realigned the wheels with 2.4deg camber & zero toe

IMG_20220405_223505.jpg
IMG_20220405_225308.jpg


went for a drive and noticed a few differences to the old BC V1, which had stiffer springs btw:
  • Steering doesn't 'clunk' anymore when jiggling left-right whilst stationary (the old coilover had slightly worn top mounts & damper shaft bushing)
  • Much better traction (during launches, fast cornering, over crests, cornering over rippling road) with dial at full soft, probably due to softer dampening & softer springs
  • Absorbs bumps alot smoother with less harshness with dial at full soft (maybe softer fast-bump setting)
  • More progressive handling/weight transfer during cornering
  • Passenger mirror no longer shakes as much (means less vibration is transferring to the chassis)
  • Old coilover has lost 10mm of available travel compared to when new (meaning it's lost some oil over 11yrs and the floating nitrogen piston has travelled further up, reducing the overall travel space inside)

Manual cruise control

With an upcoming long 4hr journey to/from Silverstone for japfest, I decided to make this crude hand control so that I can switch between using my leg or hands on the throttle

handle1.jpg


printed & glued handle together

cut a slot across the pedal to hold the bicycle cable, which can also be easily slipped off by my foot whenever I wanna disengage it

IMG_20220407_193753.jpg


IMG_20220407_195549.jpg


works nicely along the motorway ?

with an upcoming trackday, my current GTIR front brakes (2yr old) seemed slightly too rusty, worn & scored.
so as a precaution I brought a fresh set of disc & pads (blueprint ADN14364 & Borg&Beck BBP1156) for use on trackdays, and use the old set just for daily commutes.

IMG_20220408_180331.jpg


soo shiny, I just had to fit them immediately ?

IMG_20220408_180744.jpg


IMG_20220408_180814.jpg


the rim of the discs are stamped:
BLUEPRINT E11 90R-02C01275/30986 ADN14364 0141 BD26360 0208 MIN THK 23.9MM

the old discs have a larger 9.25mm vent but less mass,
whereas these new blueprint discs have a thicker mass but reduced 6.50mm vent slot.

IMG_20220408_181113.jpg


removed the old brakes

IMG_20220408_200645.jpg


hmm the lower ball joint dust boot is ripped, needs replacing soon

IMG_20220408_203303.jpg


wirebrushed rust off the hub face

IMG_20220408_203250.jpg


old brakes are slightly worn.
FR disc worn from 26.05 - 25.56mm (0.20 inside, 1.04 outside)
FL disc worn from 26.05 - 25.47mm (0.43 inside, 1.20 outside)
minimum limit is 24mm

pads have worn from 14.90 to 13mm

IMG_20220408_203954.jpg


cleaned the carrier cage to make sure the pads can slide smoothly

IMG_20220408_220901.jpg


new brakes fitted ready for bedding & the long journey down on the weekend :cool:

new brakes assembled. they feel like slippery stones at the moment until they are fully bedded in after few hundred miles

IMG_20220409_104241.jpg


began wiping & polishing the engine bay

IMG_20220409_111158.jpg


all clean & ready for the show tomorrow :cool:(y)

Quote (9 April); “my current GTIR front brakes (2yr old) seemed slightly too rusty, worn & scored.”

I noticed your photo shows 2 year old discs that appear more scabby & wear rigged then my K11s 24 year old 61K Nissan OEM discs & this effectively questions the efficacy durability of GTIR & other aftermarket brake parts?

bare in mind they're driven to work every day, through all weather including salty winter, and pushed extremely hard during occasional trackdays , I'd say it looks normal given it's application and budget.

the piston or inner pad sliders might've been sticking, causing the inside to wear more with a lip.

2022-04-10 Japfest Silverstone

After not much sleep, I set off at 3am to meet with a convoy in leeds

IMG_20220410_062010.jpg

IMG_20220410_055851.jpg


8am we all arrive at Silverstone to join the MicraMafia stand. a lot more cars & members turned up this year

IMG_20220410_081656.jpg
IMG_20220410_091518.jpg
IMG_20220410_100942.jpg


it was a lovely sunny day and omg this show was insanely huge & brimmed with cars & crowds. I only walked round 75% of it till my legs had enough and I was overwhelmed with the ocean of cars to look at o_O

IMG_20220410_120548.jpg
IMG_20220410_133349.jpg


everyone leaving the show at 3pm was a gridlocked nightmare ?

whilst stopping over for a break, fuel & checking the car, I noticed the coolant tank was almost empty ?
eek that could've almost overheated.
I topped it up with water and it leaked out ?

IMG_20220410_192925.jpg


found the plastic bottle had a tiny crack at the bottom ?
bit of ducktape sealed it enough to get me home ?

The 2yr old lower ball joint has been knocking really badly whenever the offside wheel go over bumps and also found the 5yr old ball joint dust boot has torn from the steep angle, allowing water in

IMG_20220408_203316.jpg


taking the lower cover off and eww
the water & crap leaking through the broken rubber boot has turned the red rubber grease into solid rubbery gunk which obviously ain't helping the bearing ?

IMG_20220412_210003.jpg


moving the suspension throughout it's travel, I discovered that the bearing sat at the wrong angle relative to the hub extension and the lower arm.

the bearing is only aligned straight when strut is fully compressed ?
but rests at a steep 22deg when fully drooped/relaxed.
SKP says the max bearing misalignment angle is just 19deg! so it's definately damaging the bearing & stretching the dust boot everytime I lifted the car ?

calculated I'll need to angle the end of the suspension arm by 12.5deg to keep the new bearing within it's operating range

IMG_20220412_210710 compared.jpg


removed the lower arms

IMG_20220412_214213.jpg


there's always one last bolt that fights to come off ?

IMG_20220412_223533.jpg


bit of patience & lube and bolt finally comes off without sheering and both arms removed

IMG_20220412_230118.jpg


jesus, look at the horrible offside bearing ?

IMG_20220413_001833.jpg


nearside bearing ain't as bad but still contaminated with moisture and worn slightly sloppy

IMG_20220413_002403.jpg


removed the bearings and cleaned up the arms

IMG_20220413_192451.jpg


IMG_20220413_192507.jpg


the nearside bearing still has a shiny ball but the teflon lining has worn out & turned mushy

IMG_20220413_192616.jpg


the offside bearing was seriously ruined by water, turning the grease to goop, rusting/pitting the chrome ball which shredded the teflon lining apart and making it loose

IMG_20220413_192647.jpg


chopped it open for a better view

IMG_20220505_205547.jpg


wirebrushed all the rust off to inspect the old welds

IMG_20220413_204851.jpg


passenger arm still intact & ok

IMG_20220413_205014.jpg


drivers side also fine

IMG_20220413_205117.jpg


IMG_20220413_205211.jpg


measured the bearing mount angles relative to the arm and found the passenger arm is 2deg steeper and 1mm shorter than the drivers side ?

IMG_20220413_212440.jpg


to correct this issue I cut a slot near the ends

IMG_20220414_190615.jpg


angled them upwards from 12deg to 24.5deg

IMG_20220414_192011.jpg


and welded small plates over the slots from both sides

IMG_20220414_203515.jpg


IMG_20220414_203819.jpg


IMG_20220414_221515.jpg


IMG_20220414_205726.jpg


this should hopefully reduce premature wear for longer.
just need to paint them & fit new bearings ?

brushed KuRust all over the arm to slow down the existing rust

IMG_20220415_132300.jpg


primered

IMG_20220415_141449.jpg


black was bit too boring so I sprayed it red instead ?
I recall from matt endeans comment that the brighter colour may also make it slightly easier to spot any cracks earlier

IMG_20220415_164751.jpg


fit new bearings

IMG_20220415_170637.jpg


reinstall the bushings & dust boot

IMG_20220415_192220.jpg


new dust boot seems ok

IMG_20220415_192248.jpg


arms installed :cool:

IMG_20220415_204451.jpg


IMG_20220415_204550.jpg


measured the new range of motions and it's perfect ?

the ball joint angles only max out at +-6deg from compressed to drooped (SKF bearing max angle is 19deg),
and at normal ride height, the joint sits pretty straight, which will help reduce bearing wear when steering and reduce stress on the rubber boot ?

rest of the suspension installed & swaybars regreased

IMG_20220416_123519.jpg


IMG_20220416_123537.jpg

IMG_20220416_145809.jpg


went for a test drive, chucking it round corners & bumps etc and it's fine. suspension is soo much smoother & progressive feeling with no more little clunking noises :cool:

resprayed & labelled the old rusty catch can lids

IMG_20220416_202701.jpg

went to a last minute classic car meet over the easter weekend

IMG_20220417_144502.jpg


visited a local m8 Jack to grab a few spare goodies ?
-pair of front windows (my 1993 windows are really scratched)
-rear bumper beam (min has rusted away & bent upwards)
-rear 1/4 (hopefully a bit easier to chop out the rotten lip & weld on this spare arch lip instead of rebuilding it from scratch)
-modify these manual window mech to fit my electric window motors

Last night after a car meet, kassandra's clutch pedal suddenly dropped to the floor & broke down whilst driving home :oops:
pedal felt light, couldn't select gear and reverse kept crunching, so the clutch definately ain't disengaging.

I managed to tighten the cable all the way to make it barely work, but she squealed & shuddered badly so I nursed her home using minimal clutch ?

IMG_20220420_195258.jpg


drained the dark gearbox oil

IMG_20220421_182442.jpg


IMG_20220421_182450.jpg


usual amount of debris on the plug

IMG_20220421_182513.jpg


removed the gearbox

IMG_20220421_203901.jpg


ah crap, so I guess the clutch fork had enough of the strain from the heavy pressure plate after 10yr of use/abuse and snapped off ?

I believe the cause of all this is the old grease I put along the release bearing/input shaft collar, which is now a very sticky dry goop mixed with clutch dust. I've had this issue all the time ?

This dramatically increases friction making it harder for the release bearing to slide along.
It explains why the clutch felt harder & harder in the past year, even after I re-oiled the cable several times.
Since I've already reinforced the pedal box, cable ends & cable mounts, the next weakest link to fail from all the stress are the thin clutch forks ?

After it broke and I tightened the cable really hard to get her home, it bent the release bearing plastic collar at a wonky angle which is why it squealed & shuddered.

IMG_20220421_204002.jpg


the clutch itself looks fine

IMG_20220421_215200.jpg


IMG_20220421_215645.jpg


gearbox side of the plate wears more than the flywheel side

IMG_20220421_215711.jpg


IMG_20220421_215754.jpg


IMG_20220421_215830.jpg


according to my records, it still has approx 21,000m or 2.5yrs of life remaining.
I best look for a replacement ?

swapped over to a spare gearbox to save time & make mondays trackday
