    should i feel a difference?

    right my sri t (mk4) was using a lot of oil. so i decided to change the turbo for a vxr unit and the cooling mod. but then i thought why not get the head gas flowed. im also adding a FMIC and a cool running thermostat. do you think without a map i will feel much difference for now?

    The mods already on the car where a dump valve, stainless exhaust with the main cat tqaken out not the pre cat and the 2.2 airbox. could anyone guess what sort of bhp it will come out at before mapping
    SRi-T Probably just over 200BHP

    without a map you prob won't feel much of a difference. I didn't after i fitted my intercooler. but the remap made a huge difference

    My car pulled harder after I fitted the FMIC and a flowed head would help make a difference if done properly, but as said, a remap would make the most difference.
    Getting a headjob and fitted up can be costly though unless you can do it yourself.
    Does your car pass the MOT OK without the main cat?

    i changed my turbo for the VXR one and had the head gas flowed, it didnt seems any quickers but seemed to pull stronger than before! I am sure once the interecooler is on and been mapped it will make a big difference!

    Fitting the FMIC and VXR turbo made mine quicker and smoother too.

    This was my rolling road graph with the above fitted:
