300+bhp, how easy??
 

I have a MY00 impreza turbo, how easy is it to get it 300+bhp? cheers for any help :thumb:

Power Fc or ECUTEK
Decat exhaust
Uprate fuel pump
Uprate fuel pressure regulator
STI panel filter
About 1400 for the above new but will safely see 300+

Knocklink
Air Fuel Ratio meter
Dawes device
About 200 for the above new but will dodgily see you to 300

can't see the standard UK MY00 turbo doing 300bhp at either star or dastek. learned a while ago never to say something is not possible as then someone manages it.

knocklink a must if you try , especially on the standard top mount inter cooler which will be struggling to keep the intake temp down , before detting with hard use.

Yer and replacing turbo with a TD05 doesn't even always help break the 300 barrier. :rolleyes:

I've heard it's bad news fitting a high pressure fuel regulator, is this true? cheers for the advice :thumb:

I'm considerin changin the intercooler, would uprating the top mount intercooler be advisable or go for the front mount? cheers for advice :thumb:

Look at this thread

if you plan to track the car , chase motorbikes or do top speed runs I would go for a fmic . many get good results using a newage top mount but I do not know how it would cope with a flogged turbo, lap after lap on track.

standard reg with new Walboro 255 l/h fuel pump upgrade will be fine.

I would look for a vf28 (P1/sti) turbo as a nice turbo on a UK engine.

edit to add bit about newage top mount

Full decat exhaust
Powertec induction kit
TD05 FE turbo
Uprated fuel pump
FSE
Apexci pcf
HKS EVC 5 boost controller

Mapped by Andy F and achieved 320 bhp with 300 torque.

Used just over 95% of injector capacity (380's) and retained standard tmic.
No det at all on knocklink (1.3 boost)

TD04 restricted power on mine to 294 bhp for reference.

Car was UK97 turbo

Stock TD04 will not relaibly make this power. Better fit a hybrid TD04, vf34/35 or a TD05. Especially if keeping stock TMIC. A remap should be included too.

If you do go for the VF35 turbo remember to get the wastegate ported so you wont suffer from "boost creep"
Newage top mount STi intercooler should be good for approx 420bhp so would be fine for your 300.
If your anywhere close to Glasgow speak to Willy at Meercat custom exhausts or Bill or Colin Greer at Greersport for advice, both are top notch

my turbo back system from them was £550 made and fitted

You'll struggle to hit 300BHP with the TD04.
Change it to a VF24, VF28 or VF29 if you are bothered about spool.
If your not so bothered then VF22, VF23, TD05, TD05/06

I'm running between 309 & 320 depending on air temp with a VF28 @ 1.3bar on an MY00 UK

Are the newage top mounts a straight swap or is there any modifying to be done for it to fit? My big bro just bought a P1 today so i might steal his turbo :lol1: Also what is better, remappin or chippin the ecu or are they the same? Cheers
Brian

No theyre not a straight fit, they're a PITA to fit! The wrx one is a bit bigger but requires different brackets and the STI one (the one you really want if you want to keep the TMIC) involves changing or modifying the clutch fluid resivior.

td04 hybrid - £670
standard TMIC - £0
