So, i,ve been looking over that sticky on the series 1. Now with the new aftermarket how much would I have to invest for another 50 hp, 50ftlb?

Nitrous? I want to know to, my car sucks right now but it feels really torquey and sounds awesome.

Besides Nitrous probably at least 500$, if its not a supercharged car. Just geussing though

Just get a full exhaust setup and a really good Intake setup and you should have a pretty nice gain and superb sound. My guess is slightly under $800 depending on the exhaust.

Its pretty hard to say even by using comparisons. Some engines cams were extremely weak so phenominal gains could be had, others were closer to "good" and offered less gains. You could pick up their .494"/.508" lift cam and possibly get it right there, but I wouldn't consider it a plug-n-play cam...too large. Who knows....I'll tell ya, go to www.streetcommodores.com forum and ask them! They were never offered a supercharged Series I so thats a good start when comparing mods. Take a few minutes to browse around first and see if anyone else has modded theirs. I've had my hands full with a few other things I'm working on so if you find out anything let us know

nawzzz
