Hi all I'm after 400hp currently running 346 my engine has been rebuilt with mahle Pistons ect 6speed being fitted soon next week I would just like to know what other mods I will need to do bar another turbo current spec walbro fuel pump STI pink injectors STI tmic simtek ecu full exhaust system vf34 turbo cheers in advance

 

Knowing what car you currently have will help, although I suspect it's either a Classic or a Newage WRX based upon what you've said?

 

I was looking at this for my STI:

FMIC
Turbo - Im looking towards a SC42
Upgraded fuel pump
Bigger Injectors
Remap again and should get 400 out of that!
(Dont think I am forgetting anything.)

 

I'm heading for the same path.

 

Spark plugs
3 port solenoid
3" exhaust
Fuel pressure regulator
And lots of money

 

Rcm induction kit. Is ur car sti or wrx?

 

^^ Yeah induction too. Ive a big K&N Typhoon with cold air feed, seems a good job.

 

I have a wrx but engines been built better as it decided to **** it's self a while back currently have a 3" exhaust system and an aps hard pipe inductions 380-400 would be my goal

 

Might not need bigger injectors if 380-400 is ur goal. Possibly think about ported headers and matching up pipe. Try as performancehttps://www.google.co.uk/search?q=cat+6+wiring+diagram&ie=UTF-8&oe=UTF-8&hl=en-gb&client=safari#facrc=_&imgrc=VAkg8x_8QqoorM%253A %3Bundefined%3Bhttp%253A%252F%252Fwww.warehousecab les.com%252Fprodphotos%252F568B-straight-through-diagram.jpg%3Bhttp%253A%252F%252Fwww.warehousecabl es.com%252Fhow-to-make-a-cat6-patch-cable.php%3B550%3B260

 

Ignore the internet talk. Fat fingers and iphone don't work well

 

So really all i need is a bigger turbo? Will my walbro fuel pump be enough for that power?

 

I'm heading in the same direction after my engine had a 'moment'. Going with forged 2.1 (inc, rcm oil pump and sump baffle), 800cc injectors, HDi Fmic <due to fitting that, my RCM induction wont fit, so have a K&N ready to go, but might swap for a Perrin (if that will fit), RCM headers and up-pipe, Fuelab FPR, 3inch Cobrasport turbo back and a aet billet TD05 20g, SWR 290lthr pump. Think that's most of it.

 

What's the rest of the car spec like, in terms of brakes, suspension etc ?

 

Forgot 3port boost solenoid, remap (to be updated when finished) twin maps a/l and launch. 6speed non dccd, exedy pink clutch, brembos being referbed at the moment, godspeed disks, orange stuff pads, bc coilovers, rota grid drifts 9.5x18 with nankang 245/35/18 Cant think of much more tbh mate, but its been quite a job from near standard silver wrx.

 

Looks gd m8

 

Thanks B3nmw, hes getting there

 

the walbro will cope easily, just to consider a Fuel pressure regulator, Fuelab or similar to get the best from the injectors
Trev

 

Now for a turbo choice will a td05 18g hit 380 or the more laggy 20g? Or just spend a grand on an sc38
