i have an 81 gsl and im putting an s5 turbo on it. it will have a streetported 12a with a modified nikki, a 3 inch exhaust, and the s5 turbo. what kind of horse power do you think i will have? also. can anyone tell me where to get some jets for my nikki so i can tune it?

 

well for starters how much boost are you plannign on running? type of intercooler, if any? etc.. rough guess id say 200 fairly "reliable" hp you could more more easyily
