what mods ?
 

hi everyone , my car "2002 wrx" has been off the road for a year and a half now and its finally being rebuilt at api :D its having an sti spec engine rebuild and it has a vf34 turbo , sti tmic , 550's ,walbro,full de-cat and having ecutek remap . im expecting around 330bhp ?? but sometime in the near future i WILL get bored and want more , so the target will be 400+ . i realize an sti gearbox will be needed ? and after that im planning better brakes a front mount intercooler and a fuel pressure regulator . which turbo charger would you lot choose and which injectors ? thanks for any advice :thumb: just thought id start searching for info early :D

Mine runs a TD0520g modified by Harvey Smith, has been dyno-ed at 422 bhp. FMIC is a good idea, which means using an intake kit.

Who is going to be mapping it?

You need to budget for 6-speed box and uprated clutch.

Are you having the 2.5, or the 2.0 litre conversion?

there's another £4k for starters :(

Your biggest issue if you want go for bigger turbo is gearbox,you will need 6 speed or PPG plus clutch and from this i would go for turbo etc.

For 2.0L i would go with SC42/SC46 or Harvey 20G
650cc injectors
FPR something like Aeromotive,FuelLab
Harvey selling HDi FMIC which are proven and good

No at least i would invest money to brake,OE 4pots are not the best for New age,Brembo or K-Sport will be in my view best solution

Groan, do you expect your nine year old suspension and brakes to cope with 400 bhp ?

Upgraded STI brakes, and probably coil-overs as a minimum.

Then stick some bigger injectors in, no need for the FPR swap then, FMIC is good when heading past 400 bhp.

Turbo depends on your budget.

All IMHO.

P.S. You will need to budget for an uprated clutch too !

sticking with 2.0 ltr . at what revs does the 20g reach full boost ?

amazing to think of the money people spend to get their wrx to 400bhp mark isnt it ? and these i believe would be good prices ?
brakes £800
coilovers £600
turbo £1000
6spd fitted £ 3500 ??
clutch fitted £ 600 ??
intercooler £400
fpr £200
and then pay for it all to be fitted and mapped !!!!! :freak3: shiiiiit !!!!!
didnt realize it would be around £8000 !
maybe i should concentrate on brakes ?

Its not cheap and at end we are owners of WRX bought wrong car for 400bhp+

As you are said get good brakes with coilovers,some ARB's and Droplinks and you have nice car there.


Jura

yeah your right jura should of got sti :cuckoo:
oh well all part of the learning curve !

You'll also be very lucky to get it to last at 400 bhp...

STI lump takes that with ease.
