Hey Guys,
I'm Back! I was at school all year, and I just got my car running again. I replaced my stock P30 Pistons with PR4 (B18A) pistons, (for low compression), and got all new rings. I did all the work myself, as usual, and it runs like a champ. Here are me specs:
B16A block
GSR head
PR4 pistons - 8.75 compression ratio with this setup
custom manifold with a 14b turbo from a Galant VR-4
Conquest TSi Front mount
I have an Uberdata tune, with 450 injectors, also from a VR-4.
My tune is great, and I'm running around 6-7 psi, but I've heard of some people with B18A/B's (along with T3/T4's) running around 10-12 psi. With my C/R of 8.75, this is almost a point lower than B18A/B's, and my smaller turbo, I should be able to run even more than that, and I'm thinkin I could get away with 13-14. Anyone know of any PROPERLY tuned LS motors and what their running, along with the type of turbo they have?
Any help would be appreciated
Thanks
