Thread: Getting prep started on the turbo GTP.

How happy were you over all with the IS4 on the blower? Cause I am thinking of doing it myself.

I was pretty happy, until I hit the wall in what I could do supercharged wise. I have had a few cams in this car from the NIC, IS4 supercharged and now the IS4 turbo cam. I loved it in how what it gave me at that time. But, the supercharged set up left me wanting more power and that is why I went turbo. I love taking a cruise and have a Vette that pulls up and has no clue what just happened a few seconds into trying to blow me away.

It was a great cam, but to get the most out of it. I intercooled it, heads, ported work on the supercharger, LIM, and more. It was fun, but after going turbo I could never go back to what I had.
