Sorry to bring back an old post from the dead... but I'm thinking about upping the P1 (intercooled) to an F1. Will ATI take back the P1 and send me an F1 for a discount? I found a post with someone else saying that it was $2,100 to upgrade from a P1 to an F1... $1,400 doesn't seem like a bad deal to get some killer HP (sell P1 then buy F1).

So, right now I have the Cobra tank/fuel assembly and 39# FI. To run 15psi and an F1, I would definitely need a built shortblock. I would imagine I'd also need some 60psi fuel injectors. Other than that I can't think of anything else that I would need.

Anyone have any ideas on the cost for the following or give recommendations?

1) F1 (~$1,400 - $2,100)
2) 60# injectors ~$300?
3) Built shortblock ~$3,000? (Or should I just get forged pistons / crank / rods / ARP studs and keep the block?) Looking for the best value here.
4) I imagine I would need to build-up my tranny a little bit, but that can be considered later.

Would like to be in the 525-600 rwhp range on 91 octane (if possible). Thanks to anyone that replies.
