I HAVE A 1997 WRX STI TYPE R AND IM JUST WONDERING IF ANYONE COULD TELL ME HOW MUCH BHP MY CAR WILL HAVE ONCE ALL MY MOD ARE COMPLETE? 2.5 SHORT MOTOR
AF TD05 20G
FULL DECAT SYSTEM
TUBULAR HEADERS
HYBRID FMIC
K/N INDUCTION KIT
255 WALBRO FUEL PUMP
APEXI POWER FC(MAPPED BY ANDY FORREST)
550CC INJECTORS
LARGER SAMCO INTAKE PIPE
LIGHTENED AND BALANCED FLYWHEEL
V5 CYCLINDER HEADS

 

Would guess around 340 bhp with similar torque

 

With that 20g, you may even get around 380bhp.

 

Depends what internals you have aswell.

I was always led to believe the maximum boost you can run on the 2.5 engine is 1.3 bar, enless you have forged internals. (please note i could be wrong!!!)

 

Mine runs 1.3 mid range, VF35 with forged internals - currently at 340 BHP.

Going to change the Turbo soon for 400 bhp.
