Does anyone know what injectors come standard on a classic wrx import?

Thinking of what mods I need before I plan for re-map. With a TD05, de-cat & up-pipe, FMIC, aiming for 340bhp on standard internals... is this achievable on these mods?

Cheers!

440's will do it but you may have 380's depending upon year. The rest should do it but you'll need an ECU. And a gearbox when yours breaks

He's got a TD05 ;p

Not at standard fuel pressure it's not but don't get hooked on figures, the hit from a well set-up TD05 can and will destroy the standard 5speed at far lower power outputs.

Increasing fuel pressure and using a fuel additive could give the potential for a real 340bhp.

Just had mine mapped this week (By Pat Hurbourne) with a TD05 on standard internals, was told what I have now is the safest before things start to break 320.04bhp, still very happy bunny..

i have a set of 440's if your intrested . some wrx's have been knwn to take well over 320 on std internalls.

Just realised after reading the above thread, although I said mine is standard mine does the 440's already being the later MY00 I beleive..

My MY00 survived 333 bhp but the torques were only 310lbft. The very first time I put my foot down at 350lbft it exploded

am i just lucky??? iv got a 97 type R sti with dccd obviously I have a forged 2.5 with all the goodies including a GT35 turbo I dont drive like an idiot (usualy) but admit to seeing 8000 rpm in top gear and getting there as fast as it could but i have no tranny probs at all and i read all the time about how 340 hp will kill a stock classic gearbox I have way more than that but cant seem to hurt it ...is the typr R box different???

i think they are slightly stronger than wrx/uk boxes but at the spec you have if you launch drag style id expect strange noises and not a lot of movement,speaking from another typeR owner destroyed gearbox and clutch with 300/300 but did a LOT of track drag days and 8k rpm in top with that spec id hope you were on a private road

My 2L had problems with 350 bhp and 5 speed, would shake gearstick (well, like bad rumble but no noise as such through stick) in higher gears flooring her - they wont last.

I do love the 2.5L forged route though, had to change everything, even my 6 speed box needs some TLC soon. Not long changed the engine/box mounts for Cucso really hard items as the sti stuff just isn't upto the torque.

Back to topic, get pump uprated and fuel pressure reg, plus decent map..but dont expect box to last long with fast starts or high top speed runs.

So if I was looking for an upgraded box @ some point after modding and a good re-map...is there a specific box that would be safe at 340bhp?

Does anybody know a good mapper in the south london/kent area at all!? dont mind an hour or two!

N602 WRX

later TY754 box should be ok with that..

sorry to hijack the thread
but i have a my00 uk just been remapped by JGM to 260bhp on just a sports cat and cone filter, i have just brought a vf35, wallboro fuel pump, 3 port solinoid ,
hoping to get into the 300's when fitted and remapped agian

so is my gearbox going to be safe ??

which injectors does my car as standard ,

cheers phil

Depends how you drive it mate to answer your gearbox Q, your injectors are 440cc .

I know a very good mapper in Swindon - Bob R of BR Developments, top bloke.

Engine or gearbox exploded?

Floyd

Gearbox. It's the torque that kills boxes apparently!

Phil, I was OK up to 333bhp with a VF35.

knowing sod all about ECU's, I have checked what one I have today...and I've got a Z5... Is this any good or do I need to replace it?

at what boost if you dont mind me asking? 1.2? as a guess

naughtyhunnybunny

iTrader: (7)

1.3 I'm 99.9% sure that's what Pat said..

ok. about a year ago i made 310 on 1bar td05

Badbird

we had the car on the dyno 430 hp 400 ft lbs with a weak wastegate actuator that wont hold enough boost
it has a simtek with anti lag and launch controll
my son launched it off the launch controll a couple of times (on private property) and is trying to break the gearbox generaly to justify a new one, It wont break after a week of thrashing it...

Bad bird, if that's your torque curve then I'm not suprised.

Get yourself a 321T as your GT30 isn't doing the business, especially on a 2.5. It doesn't look very good to me. It looks hugely laggy too.

Badbird

yeah its not good but as i said there is a wastegate problem JGM said its a realy good turbo and should be well into the 480+hp range but when he mapped it the thing was playing up real bad we expect a lot more but its still 400 ft lbs of tourqe it should be smashing this gearbox to bits my turbo was custom made for tracktives own car to their spec, their car was realy strong with this turbo..Owen solutions built it and rate this at over 500 hp when its fixed
