I am currently rebuilding my sapphire cossie 4x4. spec on what i have done is, t34.48 turbo with -31 actuator, grey injectors, 044 fuel pump & loom, new standard pistons & rings with valve cut outs, bottom end shell bearings, aitec rad, airtec rs500 intercooler, group a head gasket, black sfs coolant & boost hoses, uprated clutch, and 3 bar map sensor.

would anybody be able to give me some advice on the best place to go to get it mapped? also does anyone know what sort of power i will be looking at with that set up im hoping for close to 400bhp.

Any advice on things i may have missed or should add all advice is welcome pics will be added soon when it is finally complete.

cheers.

 

You wont get even close to 400 bhp with that turbo unless you run the turbo out of its threshold ( basicly run way more boost than it is designed to do ) should see 350 to 360 on the turbo at correct levels of boost though and where you are turbo systems or nms are not to far out your way

 

As said above on a .48 you wont be able to achieve that power. Change the exhaust housing for a .63.
