Looking good man!

I picked up an s14 370cc rail and injectors last night

Came out a 36000 s14 from my boss for free

Can you put some pics up of your modified fuel rail please Paul, seems it's proving quiet difficult getting the rail adjusted

Cheers mate and I bet you cant wait!
just a sec...

Could you please verify that the TB will fit with that rail pollyp:) TIA
the modded rail that came with the turbo setup or the 200sx rail i just ordered?

hang on, just take a pic of the modded rail.

will take pic of new rail when it comes

thanks mate, have you got 2 nistune ecus? are you keeping the modded fuel rail and just swapping to 370cc or you making a new rail from the 200sx?

if so wanna sell that too lol?(Y)

yea got 2 nistunes. one mapped for current n/a setup and one mapped for the turbo setup (ed will remap it). will post nistune board etc in buy sell after the project

will be using the custom rails and swap the 370cc onto it

oh god, just did some rough sums and since i brought the £700 turbo setup off ebay upto now I've spent £1000 on parts to get it runnin, £178 to relocate battery, and £833 on LSD:eek:
plus extra £200 insurance increase, £150 remap, £70/hr dyno, estimated extra £104 a year running on 98ron

in total, the turbo/lsd conversion will cost me this year bout £3.3k :wow::wow::wow: bloodi heck (£3k parts & labour, +£300 running costs)

no wonder my wallet & brain is screaming away in the distance:laugh:

TNT guy came tday with big box :)

new pressure plate, prob almera? the plate outer diameter is 190mm.

it looks like a purpose built one to me paul, with cute cut-outs for the bolts eh (so that the 190 plate will fit inside the 180mm pcd/boltholes)

local motor factors and a gearbox shop said the speedo gear is too close to the bearing to extract. the gearbox guy said he'll have to cut out the old bearing cage, pull the inner runner out, swap speedo over and press new bearings in £15each, done tomorrow.

^yea doin any mod or custom job for such car is never an easy bolt-on pain-free thing. makes it an interesting journey though.

was impressed the gearbox shop guy knew twas a micra diff instant he saw it without telling him, though he prob seen billions em, and said "lsd on a micra?" fwn

roughly comparing to the modded rail, looks like the 200sx rail injectors are too wide apart and the mounting brackets are in the wrong place. right, after me trip back from hong kong, get the injectors cleaned and fit onto modded rail with new seals & a swapped pintle

here's the 200sx rail compared to the modified sr20de rail on a micra manifold

purple 370cc injectors.

DSC04093.JPG
DSC04094.JPG


a neat treat that scopez told me on getting stuck injectors out is to swivel em till the plug head is near the corner of the injectors metal housing, stick a flathead between the gap at the bottom of the plug head and the housing and either pry or twist the driver to force the injector out.

DSC04095.JPG


370cc vs 256cc. only visual difference is the colour of the head and the small plastic cage near the tip

DSC04096.JPG


tried to take out the broken pintle, ended up having to split it with craft blade. anyone know of a non destructive way to remove em so i could swap between the injectors?
or shall i cut em off cos a read that the pintles are just to protect the nozzle from damage during fitting/prevent varnishing/keep the o-ring in place and that removal has no affect on operation. or fit new o-ring/cage filter/pintle kit for £30 after ultrasonic cleaning?

Nice one mate glad you got them ok and out the rail with ease (Y)

mentioning about the differences between the injectors, You'll probably notice that the plastic cage on the injectors from the US are higher up then ours, dunno what the differences are as there still the same size :wasntme:

Had the same problem with my pintle caps to polly, only i broke one of mine when removing it from the car(so delicate). I think there important for the spray pattern as well as what you said mate. I managed to swap my pintle over by using a flat small screwdriver and stanley blade, you just need to be able to gently prise it past the groove, kinda like a circlip...although I must say it was NOT easy but got there in the end..if its easier get a new set.

How did the injectors go in? nicely?

yea i saw on some pics of the same injectors and on the injector rebuild kits that the side feed gauze were higher n broader.

tried removing pintle with flathead but it just squashes the o-ring or deform the edge lip of the pintle.

afew forums say removing the pintle didn't affect the injector but it prob does stop the small o-ring from being pushed out by fuel pressure or sucked by manifold vacuum, ingested into the engine and cause a big injector leak/run very rich. but can't justify paying £30 for full kit to just replace a single pintle so will try to swap instead.

actually does the ultrasonic cleaning shop take the injectors apart to clean? if so they could do the pintle swapping for me whilst cleaning?

injectors fit in snugly with a push n twist.

I have 370cc purple injectors (just need a fuel rail), and one of them has a broken pintle cap, but i dont think i will put new ones... :wasntme:
 
you can deffinatly get the pintle off mate, i think it was abit easier on mine, as the sentra rail with 1.6 injectors I had was alot more worn and slightly more flexible to prise. The only thing I was concerned for was the spray pattern of the injector which is what I read somewhere.

No forget the 30quid kit mate, I did come across just a packet of 4 pintle caps for the nissans injectors on ebay when I broke mine, but never got them cause managed to swap it over. I was just having a look for you but nothing yet, ill keep looking and post it if I find.

The ultrasonic cleaning is like a flush, there put into a machine and run at different rates until all flow the same, not 100% on all details, but I believe they refurb the rings too and give you a print of before and after results. I was going to get mine done before the turbo but was no need, had no problems with mine, and didnt like the idea of posting mine off to some random place lol. you should be fine

so just hoop on the new o-rings, slap on the injectors and hope for the best?
i'll try swap the pintle since i got 3 injectors to attempt on

the 256 injectors cage-mesh looks bit dry n rusty from being un-used so long but the 370 injectors appears and smells fresher of fuel so could be fine.
 
Yeah should be good to go mate, I didnt even get new rings for mine..my only error you know about already :wasntme:

with the pintle try and get under the edge on both sides as opposed to one..more like taking a hat off :laugh: very fiddly.

Yep that what my rails were like, s14 fresh, sentra dried/rusty.

Cant find that packet of four anymore mate..must of been a one off, sorry

If you wanna clean them, theres a poor mans cleaner setup on youtube. Looks easy enough to do and will be a lot cheaper. Providing you can get the bits on (not sure on clearance on those injectors) :)

just saw noddie's selling his forged piston engine for 600. would be good as a stronger backup engine incase the stock block is pushed too far.

or should i just fit the forged engine to turbo anyway so that it could either:
a- be able to withstand the 10psi 163bhp more reliably or
b- attempt for more power, risking a more expensive blowup and make the 2 spare stock engines obsolete cos they may not handle the higher power the forged engine was mapped for.

TBH i would just fit the low comp engine first, everyone i have spoken to about turboing says do it right first time. The low comp engine will handle WAY more than 10psi (when mapped properly). the limit will be getting the power down haha!
Im a bit sad to see this engine go, but i think you will use it better than i would (iv got no more money to put into mine to take advantage of the engine) so it will be nice to see it making some good power.
keep us updated!

Damn man, didn't tell me it was going dude!! What an awesome setup you could have Paul, I reckon 200bhp is possible

No offence Paul but you seem more capable to put it to use than some of us due to financial reasons, i think you could build the monster slayer!!

Ed what you going for? Mapped at 6-7psi?

hey finally got back from hong kong, twas a looong flight.

gearbox guy was off tday so gonna ring tomorrow to get the diff

the riveted clutch pedal was creakin n clicking alot under load cos the sparco pedal plate was rocking slightly on the curvier pedal face and snapped one of the rivet head off too. so i bent the sparco plate abit to conform to the pedal, riveted back on and no longer creaks

DSC04266.JPG


noddie, by low comp engine, ya mean the forged piston engine yeah? then get it mapped for more juice?
that would be an ideal thing but few issues bugga me:
- the addition of swapping the engine requires a crane = hire cost
- more time & effort to swap engine
- since the engine ya built is new n honed, it requires bedding in the moment it starts up = progressive loading & reving up to WOT. coupled with the turbo WG thats not configured for 10psi yet and the turbo map might not be matched to the forged engine, i risk either blowing up the forged motor whilst trying to bed the rings in or end up glazing the rings whilst keeping off WOT & high revs to control boost and making the rings blow badly.

not sure bout pushing to 200bhp martin cos i'm only after abit more juice down the track straights, not a mega monster that'll snap driveshafts n shred gearboxes.

i think as baguetes mentioned, the safest n economical solution for now is to simply turbo the stock engine, the mapping will be ok for driving to Ed to remap since the setup is roughly the same as kristians, and aim to finetune it for 10psi 160bhp'ish.

then when it blows on track, i'll need to hire a crane n some holidays, fit forged engine, proper bed-in the rings since the turbo WG & map would be sorted by then, and maybe remap for more boost if i desire.

You can bed-in the engine without the turbo, im testing the engine that i will use for the turbo, with a 1,75mm headgasket, and it still goes strong, not as powerful, but runs ok...

I'll have to add it to my original turbo planning schedule but I guess I could prep and fit the forged engine and LSD gearbox leaving the janspeed exhaust on, bed the forged engine in, then fit and configure the turbo afterwards before remapping?

This is what i would do if i were you tbh.
Maybe ring up Ed and see what he suggests if your taking it down there for the mapping?

agree. ok i'm thinking of popping over to brighton this saturday 19th to pickup the engine cos:
- i don't wanna cause an inconvenience for ur sister if she's carrying loadsa stuff from brighton to liverpool
- i goto pub with m8s on sunday nights, so driving to brighton or liverpool and back home, I may not make it in time
- and it'll also give me more prep time getting the engine ready for swapping before the project begins in april, rather than grabbing the engine from ur sister on 20-26th and rushing about

will call Ed soon bout booking the mapping and if it'll be ok to drive down with the turbo map on a slightly different setup and a lower compression forged engine. i think that once i fitted the turbo, as long as i just drive normally to Ed it'll survive.
