Hi guys ive owned my Impreza over 2 years now and love every second driving it.

Over the past few years ive modded little bits here and there. Just wondering what performance figures i might be looking at with my spec??

Im putting it on a dyno next week to get proven figures.

1994 WRX JDM Subaru Impreza (GC8)

Central Subaru Rebuilt V1 (closed deck block with uprated Bearings)
Z4 ecu with HKS daughter board (Running 1.1 bar)
5 speed close ratio gear box with short shift
Td05 16g Turbo
Blitz Nur Spec R full 3" system from turbo back
Apexi air filter

HKS Turbo timer
HKS EVC electronic valve controller
Turbosmart Megasonic DumpValve
Walbro Motorsport Fuel Pump 255lph
Exedy Stage 1 Fast Road Clutch

Cheers. Andy

 

280-290bhp

injectors are going to struggle with over 300bhp with 380cc that come on the early wrx

 

at a push on 380's injectors. get some 440's atleast and give your engine some vpower

 

Any supporting mods i could do to see the magic 300bhp without changing the ecu??

If i went for a mappable ecu and 440s/550s, front-mount i would see better results, but for the money i dont think it would be worth it.

300 and i'll be happy with that.

 

the injectors are holding you back, 440's are the only way to do it safely

 

Would the map run the same on 380s or 440s?? Wouldnt i need to re-map if i fitted 440s?

 

i have known 440's to fun with no issues on a 380's set up with no problems, but i wouldnt risk it my self

 

Did you get it on the rollers mate?

 

Moving house at the moment so had no time to play with the scoob.

Hopefully next week. I'll put a photo the dyno results on this thread when i do
