hi guys, i have a 01 WRX fitted with STI uppipe, STI TMIC , STI injectors and a vf35 turbo alongside a 3port solenoid. 3 inch decat milltek all way through.

currently running 325bhp/290lb/ft of torque

how do i go about getting more torque? CAIK ? ported/tubular headers?

cheers in advance all

 

Is it mapped?

 

yeah sorry, its been mapped for all the mods

 

More boost lower down the rev range than is currently mapped. Or, if the turbo's already maxed, get a bigger one.

That won't be a particular help in the power ballpark you're in at the moment.

Porting will help a little, and any aftermarket manifold would have to be carefully chosen if any improvement was to be gained, as again you are not at a level where the standard ones are a verifiable bottleneck.

Best person to have a word with is whoever mapped the car.
