3.4 pulley here same setup as you, gen v stock heads, n*, headers, Catback, 103, intake, ported lim, 60 injectors, and this is on 91oct. If you have 93, I would just add more timin to it. Personally.

gtp 89 do you have aftermarket cams?
Yes I have the vs cam. Will be running a 3.2 but on e85 and a 3.4 on 91oct.
Alright, I think I'll go with the 3.4 on a genV. How much boost are you running?
I believe it is around 8-10 psi of boost 10 being the max the car is sitting due to my tranny going out so I literally drove it for about 2 weeks once the tune got done. Personally if I were you buy a 3.4 and a 3.3 and a 3.5 to be able to switch them out and see which works best, because at the end it isn't the size of the pulley but other factors that make a bigger difference like timing.
I would have to get 3 different belts then.
Just a thought. Not something that has to be done.
Huh? You can get a 3.25, 3.2, and a 3.1.Quote:

You can get a 3.3 and I believe a 660 belt will fit all pulleys from a 3.2 - 3.5 so no need for a belt per pulley...
Click on the drop down, Intense has 2.5 - 3.6 all in .1 increases. Intense pulleys will fit on ZZP hubs as well and vise versa.
