Hey.
Just looking to see what i can do to get a little 'more' out of my GSi without spending silly bucks ....

I'm guessing that C20SEH Injectors would fit and uprate the FPR ?

Already got a 4 branch & straight-thru exhaust system on it the now & i will probably pop a K&N on it since i havent got the standard airbox...#

Also where are the FPR's located on the GSi.

Cheers
Archie.

Cheers though.

you could have the head ported and polished and a mild cam orr go down the route of throttle bodies/carbs but youll need about 400-500 pound for that

Dont do it yourself. Get somone who acualy knows what there doing!

But injectors are not worth it unless youve done a seriours bit of internal modding.

But like said search more too. A decent cam and a good service would give you more.

Although like usual id say fit a 1.6 16v, standard GSI engine isnt very tunable without spending lots of money.

I work as a mechanic so i can do the majority of work myself.

Want to leave the original engine in it as i'm trying to keep the car as close to original as i can.

Theres plenty you can do mate. Cam, pulleys, lightened and balanced flywheel, carb or bodies, 4 branch, exhaust, head work etc or a shorter ratio box for acceleration, skimmed head. Im sure there's more :)

Cool thanks for the replys.
i'll get some heat wrapping for my 4 branch & a K&N filter which should keep me entertained for the now, cars due to go on the road at the end of this month.

ive got a c16se head on the shelf i could port if interested.

tbh if want a bit more get up and go so to speak then would go for some mild head work, fast road cam, decent 4 branch
