Ive currently got the GM S2 w/ 2.9 pulley, dual pass, heat exchanger, cai, colder plugs but still have the 42# injectors. Id like to upgrade to the 60# so that im not starving the engine at high rpms, but i wanted to know how much HP gain would i see adding the 60# and tuning the car.

Im also thinking about having SMG Motorsports install their twincharger remote turbo kit to really wake the beast up, but it seems like Freds still got the thing in prototype phase. a requisite for the turbo upgrade is the injectors...but just wondering.

You won't see any power differences between the 60's and 42's but the tune alone will gain 10-15. If you do want to go twincharged I would suggest getting 80's so you don't have to re-upgrade in the future.

 

yeah 79's or 80's would be a good choice.. i beleave there are some rilly cheap 79's on this forum for sale. but ide get those if ur planing on twincharging... dont wana starve it for fule when u do that either.

 

I'll sell you my 60's for $125 shipped.

 

hmm twincharged huh... hahaha go for it

 

Wish I had the money..

 

cant go wrong with SMGs twincharge setup. i rode in it that things an animal

 

^^^ i bet it is, ive heard crazy stuff about it
