To save hammering the 'what did you do to your micra today?' Thread with my build details I'll put as much info on my build here.
I've been into K11s for years now had my first 10 years ago at the age of 14 as a write off to repair and get on the road. This was sold to a friend when my daughter was born as we needed a 'modern reliable car' aka A Ford Ka which didn't even last a year. Since then I've been involved in several builds with friends with K11s. Had a few cars since most recently being an e46 330i but none have put a smile on my face or been as pleasant to work on than my old K11. So I impulse bought my trusty K11 after pining for one for so long!

So this is how I first got it. Was advertised on gumtree for £300 however a bald tire and missing stereo knocked that down to £260. Other than being filthy and the interior smelling foul was not a bad car...memories came flooding back .

Went out for a good drive where I realised it was in dire need of a service and some brakes.

Tried fitting a backbox from another k11 build but it wasn't happening, I just couldn't get it to seal.
So chopped the exhaust up and made a side exit

Then lowered it on some cheap eBay Kilen springs i had lying about as well

Now the car wasn't so roly poly everywhere on the new springs, what MASSIVELY let the car down was the steels and tires. 155 profile high offset wheels are just not going to do. So I acquired some Renault 5 GT TURBO phase 2 wheels for cheap. These are lower offset and wider so allow wider tires (stock r5's ran 195!) I settled for 185 however for ease of acquiring tires. One pair of the tires were nearly new nankang ns20's which were good enough however the other pair were bald. These were replaced with nankang ns2r semi slicks .
This was a risk as I was very worried I wouldn't be able to warm them up as they are designed for Caterhams. However they warm up very quick and are very very grippy in the dry and damp. Rain they're about as good as normal average tires which is a shame.

As you can see I also haggard cut the grill out nismo-esque. Not sure if I regret that decision or not!
Personally I'm more about how the car feels to drive rather than chasing speed and grip etc so next up was changing things up for driver feel.

Got myself a racing steering wheel (budget but quality from McGill Motorsport I believe)
Also got a new gear knob which there's a photo of later.
Bought some JDM porn for inspiration:

And fitted some tacho clocks:

The car was still stinky though, and whilst wiring in the tacho feed from the dizzy I felt something behind the dash...

Ewwwwwww. However with mousey gone the car didn't smell anymore!

Found out my sill repair done previous to my ownership wasn't a steel patch but some fibreglass instead...still need to patch this Spilt a drink down myself whilst in traffic due to no cup holders (why Nissan WHY!?!?!) so made my own

MAF died. Sounded like launch control when I unplugged it to get home .
Bought 2 replacements for CHEAP on eBay like a tenner each or something just in case one was a dud!
And then something exciting happened.
I had an epiphany.
I needed boost.
I'd researched researched and researched turbo conversions for years.
I'm a bit like that, I love reading people's builds and experiences. When you get past the catty-ness and keyboard warriors the Internet and forums are a haven for this. Especially the man we know as Frank. His write ups here and on the Aussie site are pretty much a step by step.
I think this is key to actually doing a successful build. If you know the ins and outs of how what you want to do and how it all works nothing can really stop you? I am by no means a mechanic (actually an electrician/engineer by trade) but through a willingness to learn and research I like to think I'm not half bad.
So whilst I was stalking Franks turbo threads (using the search function) I found a thread from a year or so before where he was selling a turbo manifold. I emailed him and whilst he had sold that manifold he still had a gt15 turbo welded to his incredible burble manifold which was well documented on the Aussie site. I met the legend and parted with some cash for this:

Ohhhh baby

I knew I wanted a bare bones basic setup.
I'm not one for chasing power figures or quarter mile times, I'm all about the driving experience.
I quickly decided to use a rising rate fuel pressure regulator with some bigger injectors.
Some rough maths and using some pretty handy online calculators led me to purchase a 6:1 vortech rrfpr from the USA and some 195cc injectors from a ga16 scrapped almera.

Only have a fitted picture I'm afraid!
I also knew I wanted an intercooler. Running stock internals and a budget fuel system I wanted to reduce intake temperatures as much as I could. In tune with the budget aspect of the build I bought an Audi A6 1.8t intercooler, only a diddy thing but better than none and good quality, air tight and again cheap from a scrapped car.

Here's it mocked up, also came with a map sensor in case i fancied proper management later!

In the end the intercooler is top mount fitted. I wasted the most money on this build on piping trying to front mount. To do this would have meant long runs with tight restrictive bends.
I then took the car off the road for probably 2 months to get the turbo done, however for a month I procrastinated and did nothing!
My friend then got himself a lovely r33 gts-t which one ride out in got my ass in gear to do the turbo.
That very night the standard manifold came off!
My clutch had started slipping from several launches on the semi slicks so I set about fitting an LUK clutch.

Good idea too the old one was truly shagged.
This was a mission on my own and for me was by far the most difficult part of the build. Getting the gearbox off and the clutches swapped over was child's play. Getting the gearbox back on took 2 whole days to get on. I will never attempt this on my own again! I did however get it done and rewarded myself by fitting the turbo manifold!

Then fitted the sump with an oil drain (didn't use sealant doh drip drip) and set about my oil feed. I tried to use the oil feed on the head but the damn chocolate bolt inside just rounded it's Allen key head. So I ripped off the oil pressure sender and used that as my feed instead. This is in my opinion a useless feature of the car as it only comes on when the pressures at 0 basically.
Probably open myself up to flaming here I've used nipple push on attachments with a steel braided Teflon line for my oil feed system. It's not the best but my crimp on fittings failed out of the box and whilst Teflon doesn't clamp down as well as rubber we have clamped Teflon hoses at work running a fluctuating 75psi constantly so I'll just see how I go. The feed from the block uses a 1/8 bspt male fitting to 10mm nipple, and the turbo side uses a 10mmx1.0 thread male fitting to 10mm nipple again with 10mm Teflon hose between them. The drain had a steel flex coming out of the turbo into just a rubber hose to the sump.

Onto the boost piping. This was a rather annoying part of the build. Everything in my head was saying front mount intercooler. The intercooler even fitted there perfectly. Problem was with the turbo orientation and the front of the car itself it would have meant long restrictive runs to front mount which in my opinion would discount any improvements the front mount would make. It then occurred to me that if the battery was relocated there was an ideal space for my little intercooler to sit quite nicely, with almost straight runs from the turbo to the throttle body. Sadly I had ordered enough bends etc to front mount by this point and actually only used a third of the ducting I bought, huge waste of money! Will be nice to have some spare ducting about though.

Obviously I now needed an air filter.
I bought what I thought was a universal mushroom air filter from eBay as I didn't have enough room for a k&n style cone, what arrived was a fake hks filter, packaging and all!


As awesome as it looks like this the grill had to go back on for sleeper-ness!

There it is with a hood scoop mocked up. (Not in the right position mind just for a general idea)

When your running a turbo you want to see what kind of mad boost you're running don't you? So boost gauge time. A bare basics quality boost gauge runs you up to about £25-£30 for a Tim gauge.
That's way too easy though!
DIY boost gauge time


Hose I picked up along with this brilliant push fit splitter which allowed me to splice into the wastegate feed.

The wastegate line fitted was too big to go into the adaptor (designed for 6-8mm diameter lines) so I reused a removed vacuum line from when I fitted the rrfpr which just needed a little bit of tape to get a perfect seal (200 miles on its still airtight!)
Routed the boost hose from here around the engine bay.

Behind the dash and up to the cluster. Currently it comes out underneith the steering wheel plastics and just loops up as I don't want the line kinking.


That's a 40mm pipe bracket bought from Wickes for 69p for 2! Obviously need another turbo car .

Here's my battery relocation, it's only temporarily done to the footwell it will eventually go in the boot.

I extended the cables using something called a Henley block in the electrical trade.
They're designed for splitting mains supplies to properties.

My MOT man was happy with this he said the only thing he'd look for is that it's fixed in place not just sliding about!

Exhaust time. At this point I'd driven the car along our private road with no exhaust just the downpipe and my god it spooled hard. 7psi straight away. However it sounded mental loud.
Wanting to be as sleeper as possible and I need to mot it at some point I set about fitting my standard exhaust with the side exit to the downpipe.
The downpipe was 55mm internal diameter and the stock exhaust is around 38-39mm diameter depending where you measure. I had a custom adaptor pipe fabricated to join them.

Ewwww clamps and paste.
Will have to do till I get my welder in the next few weeks!
Only a slight escape of exhaust gases anyway barely feel it with your finger.
However with a cat now fitted and the smaller diameter exhaust we've lost a whole psi until about 5000-5500rpm
Sounds nice and quiet but aggressive.
VERY scooby-esque so I've been told! The great thing about turbos is that they actually act as a muffler, so now it's actually quieter than when I was running my side exit with both cats! Mad.

Now onto the road. Initial shakedown revealed a dodgy radiator hose clamp which blew off. Replaced with brand new hose clamp no worries.
Then this bracket fell off where I'd just finger tightened it when I was doing the clutch.

I don't think it's that important but I'll stand corrected if someone says otherwise! Will try to straighten and reattach during the week. I think it goes between the engine and gearbox?
Then when refilling the coolant from earlier I lost the cap to the expansion tank...milk bottle cap to the rescue!
Use reuse recycle
Have been noticing some smoking on startup AND a minor leak of oil from the turbo.

However the more I drive it the less and less it's leaking and smoking. It's not a lot of smoke and it only takes a minute amount to cause smoking. Once warmed up its fine.
I'm putting this down to just a buildup of crap in the seals gradually burning itself off that's preventing a good seal.

Day 2 of driving and we're onto 200 miles of boosted driving. No oil consumption or coolant which is good. No overheating or abnormal behaviour in that respect. No bogging or cutting out either! Just very very quick!
Leading us toward the inevitable!
It is very early days but obviously a hell of a lot more pressure is being placed on the drive train. What I have noticed is after hammering it especially a high speed pull I'll get some light clutch judder when pulling off from standstill shortly after.
Now whether this is down to it being a new clutch not bedded in or just a buildup of heat or even because it is the teeniest tiniest clutch in the world! My k11 is a L Reg so on the k10 gearbox and clutch. Once the clutch is allowed to cool this doesn't happen. One thing is my e46 has a vented bell housing to allow some heat dissipation. I'm thinking of adding a vent to the bottom of my gearbox to allow cool air in and then 2 smaller holes one on each side of the gearbox to allow heat to rise out of it. This would allow the clutch and flywheel too cool a lot better whilst not really allowing the Ingress of crap too bad. This is just theory of someone wants to shoot me down in flames on this feel free!

Another thing I've noticed is just how easy this little gt15 spools.
Now I have two routes to work. The most direct is jumping on the motorway 5 minutes from my house and exiting the motorway 10 minutes from my work.
Or back roads way which as long as you don't get stuck behind a lorry or tractor is nearly as quick.
On dual carriageways I've noticed holding the car at 70mph means 2.5-3 psi of boost part throttle. This constantly for about 10 minutes doesn't sound too good to me with my limited fuel setup, whereas I can drive on and off boost the back roads way as I please.
An idea I had to solve this is to fit a twist locking choke cable to the wastegate to hold it open and reduce boost on the motorway.
If anyone could offer some insight on this whether or not they think I'm a moron or not feel free, the choke cable will be here for next weekend
Also did a plug check with some new plugs I fitted during the turbo fitting. Seem spot on to be honest, if a smidge rich on idle. They're looking a little warm on heat range, which isn't alarm bells but with a conservative setup I need to err on the side of caution so I'll be picking one step closer plugs tomorrow and I'll just have to hope I don't have problems with fouling.

Done my first commute in the old girl. Performed flawlessly even in traffic

Used less petrol than my 330i which is nice.

With regards to the clutch embarrassingly I think it's it's now almost broken in meaning the biting point has changed somewhat from when first fitted. Meaning the juddering is user error on my part! Adjusting throttle and clutch positioning has cured the juddering.

I am thinking of fabricating some better engine mounts however out of solid rubber with some holes drilled in to ease vibration. I can see clear cracks in mine and with the added torque I can't see them lasting long. I need spare mount brackets to do this however so if it ends up costing too much I may just get some uprated ones like these

lookin good RYB :cool: the front mount does bugger all (i ran without it for years) and the 2 side mounts basically just hold the weight of the engine and box, the rear one takes most of the torque forces and is easily uprated with a small block of rubber

my last setup (td04 on a 1.3) would register about -5psi (ie, vacuum) at 65 mph cruise, and would,nt show any boost till about 80 mph
my current diesel (similar turbo to yours on a 1.7) shows about +5psi at 65 mph
where is the gauge piped into btw ?

I've got it piped into a T piece on the wastegate line between the wastegate nipple and the nipple on on the turbo itself. I didn't want to tap off the fpr feed as I've already tee'd into this for the rrfpr so don't want to 'overload' this source.

Ahhhh so mani pressure may actually show a lot less under these conditions?
Good to know. To be honest I'll leave it how it is for now, it's working fine and being a pressure gauge rather than compound gauge I don't know if it'll like vacuum pulling on it.

yes, at cruise you probably have +2 psi blowing onto the front of the throttle plate, and about -5 psi sucking against the back of the throttle plate
i used this draper gauge on mine (vacuum and 10psi pressure) £10 ish, but had to get a gauge like yours for the diesel

Thanks for the responses guys.
Commuted in the car all week so far, with some drives having lengthy stops in traffic. Car is performing faultlessly.
Mpg being returned is brilliant too. I'll give a figure tomorrow when I brim up the tank.
One thing noticed is the engine bay temps are rising considerably when in traffic, which is seriously heat soaking the intercooler to the point where it is hot to touch. Now when I'm driving at the weekend or night even driving hard for an hour I'll pull up and the intercooler is only just warm. Cutting the hood scoop in will help this but I am considering cutting in and fitting some louvred such as these for keeping temps down when stopped. I think these fitted above the turbo should keep the engine bay from becoming such an oven.

Not much to write about the car really. Still running strong. Done 1000 miles roughly now and the dipsticks gone down to halfway down the hashes.
Not too bad, my 330i uses more oil than that (they all do apparently) so no worries there I always buy oil in bulk anyway! May even try going thicker than 10w40 to prevent the startup smoke.
MOT was due Wednesday and I've decided rather than just patch over the rust hole in my sill I'll fit a new sill. I've mocked it up as is unpainted and I actually love the look of the Matt black sill!

So I've decided I'm going to do the other side too along with some major changes that I really need to do to the rest of the car to allow bigger brakes etc which will totally transform the cars appearance!
All will be revealed shortly
The blue turd is coming along well. Engines almost out (don't have a engine crane so taking it apart piece by piece).
Engine was definitely fit for scrap:

Golf ball sized lumps of oil slugs and metal shavings! Not good.
Should have the qg15 next weekend and the fun will really begin!
Probably just going to fit the suspension kit and wheels from the turbo to it at first as these are getting replaced shortly, it's going to be my 'sensible reliable' back up and long distance car.
Once it's on the road it will allow me to finally sell the BMW which I'm hoping to use the money raised to fund a trip to the Nurburgring. I've always wanted to do it and I think the blue turd would be perfect for it .

Started cutting the rust out of the sill in preparation for replacement on Saturday.

Found a quid INSIDE the sill couldn't believe it when it fell out with all the rust!
Found part of the inner sill was rotten through also


^all that was left of that piece of metal!

The new sill mocked up. It's a cheapo 'oem' one so fits where it touches but it'll do.
Luckily have some spare sill that I cut off to patch in the inner sill.

Inner sill is patched and I did get the top of the sill welded up right to the arch.
Made the rookie mistake of going too quick and rushing completely warped the new sill
Started blowing holes trying to weld it where it didn't want to be a voila lost patience and ripped the mother off again
Just going to weld in a simple patch instead...would've been nice welding in a complete new sill but oh well.

Booooooo stock exhaust.
Fitted it for the mot as side exit is quite loud and obnoxious!
Fitted a klarius midpipe as I butchered my stock one to make the side exit. Pretty spot on fit and only a tenner from eurocarparts.
Lost my Subaru-esque burble though just sounds like a GT turbo or glanza now especially when on boost. Quite like it to be honest bit more humble but I miss some noise. I'll have a play at some point see if I can get some of the burble back!

Also stripped the back out. With the engine ordered for the blue turd I don't need back seats in this one. Probably going to fit some better hugging seats from another car. Maybe a celica or FTO? Can pick both up cheap and with the welder I can make them fit.

Wow I went quiet didn't I?
Wasn't feeling very great in myself in the run up to Christmas ended up not coming on here and deleting my Instagram account which I know quite a few people followed.
The car carried on running great, never missed a beat. I parked it up for the winter due to it being on semi slicks and no interior meant it was cold in the winter.
Whilst parked up it got vandalised a few times, a kicked in panel here and there and the wing mirror smashed off. Nothing disastrous really I tend not to let stuff like that bother me. However as I'd obviously not got rid of this car they found so offensive they one night decided to smash most of the windows in and try and set fire to it. Luckily they failed but alas I didn't want them coming back and finishing the job so sadly it had to go.

I wasn't too cut up about it. The car was pretty ropey in hindsight. The turbo was leaking a fair amount of oil into the exhaust causing smoke on startup and gt15's are a pain to get parts for now.

I took the good bits off the red car and set about finishing the blue facelift. Which is now turbo micra 2.0!

It's on the road now. New engines good. Not turbo good but good .

I was quite excited to drive this car I've had a few Early spec prefacelifts now so wanted to see the difference.

When I got the car the PS pump was nackered. I don't like PS anyway. I removed all the hose lines and looped out the hard lines coming out of the rack after going lock to lock a few times. I've done this on a few cars now and this keeps the rack lubed up and allows the travel of pressure to loop. I then emptied the pump of gubbins and this is now being used as a water pump tensioner.
One thing I let the red car go with was the lowering springs. I wasn't impressed with them, luckily I got them for free but they didn't feel as good as other lowered cars I've been in. I decided to give cut springs a go. I cut them to give roughly a 40-45mm drop all round. The fronts are captive fine. Rears not so much. I'm going to use corsa rear shocks to reduce the droop.
On the road then! As with any rebuild there's teething issues. I had water leaks (had this with the turbo you'd think I'd learn!!!) and I had a horrible stuttering.
During the engine swap I fitted a new clutch, new oil and oil filter. I forgot to change the plugs and fuel filter at the same time and presumed it'd be this causing the problem. Turned out to be the maf being covered in junk. Cleaned with contact cleaner and hesitation cleared! Car was running great and the handling!
Bearing in mind I'm back on 155/70 13's from semi slicks...the handling is miles better than the springs! Far more planted and solid feeling. Longitude movement is great, side to side there is still some wobble there but that's down to no ARB's. Very happy with this free handling improvement! The steering rack is great too. Rack feels quicker lock to lock? Maybe just me but feels good.
So this is a coilpack engine so bit newer and fancier, it did not like my velocity stack intake directly on the TB. Real bad flatspots whereas my prefacelift loved it. Using my old intercooler piping I've got it going over the engine to behind the grill, where this works great. Using a bit smaller diameter pipe (50mm) I've got great throttle response with none of the flat spots.
The engines not quite as lively as my old one. I always found the older cg10s to be almost like my old fireblade engine. This not so much. Off throttle response isn't quite as crisp. Boosted this won't make a difference I don't think.

Start of this week the cheap universal lambda I fitted died. It was a tenner I'm not surprised but it got me out of a jam. I'm currently running the secondary lambda plugged into the primary socket . Only after doing this have I been able to get her out on a good run and the car is hitting a wall after about 50mph. You can feel it drop off at the top of second. It's not misfiring or bogging, just loses some of its eagerness. Up to this point it runs fine which is what I find weird...I thought it was down to the ecu retarding ignition with the speed sensor feed but I've disconnected this, which got maybe 50% of the lost power back but I'm still at a loss to what's causing it I've got a CEL from the single lambda being run so this seems my best bet. I'm not spending any real money on the car till April as I'm on holiday next month. This is when the magics going to happen.

I'm planning on totally redoing the turbo system putting right everything I wasn't satisfied with in the last build. I'll be welding my own turbo manifold with a flange to take a k03 turbo. These are three a penny and readily available from 1.8t's and are slightly bigger than a gt15.
They also have the added benefit of water cooling which the gt15 could've done with, managed to get it nearly glowing a few times!
I want to run a chargecooler system also. I don't like the lengths of chargepipe runs needed to front mount an intercooler, and a friends celica gt-4 runs a chargecooler with great success. My theory is to hang it off the engine above the gearbox right massively reducing pipework. This will have its own Bosch water pump and cooling system fed from a tank where the oem battery goes. A water cooler front mounted will offer cooling.
My fueling system did the job fine, now I'm on a top feed rail I'll use qg injectors.

Some pictures of the blue turd
The missus and daughter have taken to calling it Stitch from LILO and STITCH. Makes sense it being a bit of an abomination!

Fitted some new bumpers. Prefacelift rear, first facelift front in the black plastic. The blue black contrast works well. Also Laguna 15 steels on the rear and civic 15 steels on the front with an 8mm spacer to avoid the hub centre. 195 50 15s t1r's as I managed to delaminate a set of federal rsr's.
