i'm looking at a good deal on an ap2 vortech kit. I know they use a sumplementary injector in the power cooler that isn't use on the ap1, i would think the black timing box would also need to be tuned for an ap1, and the pully is smaller (4.5) than that of a ap1 kit....i was told that if i run that pully on a ap1 it will make around 12psi which is to much on a stock motor.... any input?

thanks a lot

 

The black box you will need one for AP1. You wont use the 5th injector. I think teh 4.5 pulley will yield around 10 psi but not sure on that one. There is a pulley chart in the FAQ that should show you.

 

you'll need some injectors and a ems. and 4.5 pulley should be 10psi.

 

correct about the engine managment and injectors. I would go with the 750cc just incase you decide for more power they will give you enough. It sucks deciding you need more power and your injectors are too small...been there done that..might as well get it right the first time
