or do a 8.1 swap like this famous kid on here lol

but max shot i would say 150 tuned but their are ppl on here throwing 200+ on stock bottom ends with some 4 leaf clovers in them somewhere. cough cough G cough

might take gears,tires, cam,stall,longtubes to meet ur goal

I never suggest going over 100 shot on stock motors. It's a good starting point. But turbo is much better. Tell ur dad to go boost. Even sts is better than the bottle. :) have fun

couldn't agree more nitrous is nightmare after nightmare after nightmare after nightmare and then all the turbo guys come beat up on you at track days and meets so us nitrous guys have to resort to racing the supercharged guys to get any wins or self confidence.

Limits of the 4.8 are dependant on multiple factors. With twins you could get 1200 HP as proven by a magazine (name escapes me). As for N20, I would feel safe on a 100 shot nozzle, 150 with a spot on tune, and maybe 200-250 on a direct port setup with its own fuel supply and a good tune. All that said, I'm not spraying but I intend to in the near future while I'm building another engine for forced induction. Do some research and plan what you want to do. Just remember, you can only have two of the following: fast, cheap, and reliable.
