hi, here are my cars specs (engine)

g180
balanced and blue printed bottum end.
ported and polished head
flat top pistons
stage two cam

4 into 1 pacemaker extractors
2 & 1/4 exhaust system

not sure about the carby. Its a stock nikki but i have the feeling it has modified.

Anyway, i really want to upgrade my cam. Would this help or hinder its performance? what sort of gain or loss would i get from doing so? im thinking a stage 4 crow cam?

I did originally want to do a suckthrough carby supercharged setup but it wont be to leagal so i have threw out that idea.

Thanks for your advice in advance.

Anything much bigger than a 30/70 and you really should upgrade the carby, esp if you give the tacho a floggin. See if u can find out more bout the carb like if it definately has been modded and wat was done 2 it.
do u drive da gemi hard enuf 2 take full advantage of that size cam u want ?

would a single webber do? I dont really like the idea of a mechanical secondary like on a webber but...

sorry if i sound like a wanker saying "stage 2" etc. Thats just what i was told it has. Im assuming it just has a mild cam
