Thank you very much for the information. I have 93 down in Houston. I don't have a problem with upgrading the belt and oil pump gears. Heads can have whatever is needed. I just want to make sure it all flows properly. So final questions I guess are if I am running 93 octane (I'm not looking to search out 100 on a consistent basis), should I stick with stock compression, and do I need to sleeve the block to run 9000rpm naturally aspirated with ITB's?
I do plan on doing forged pistons and rods, so money is being spent on those regardless of stock compression or not. I also plan on upgrading the coil packs.
No need to sleeve for NA 8,000+ engine, but I would hone the bores and use the MLS head gasket/ARP head bolts (and time-sert the deck). I'd run the SOS "NA" pistons, which have moderately higher compression. They should work with 93 octane, assuming you have a good tuner, but you should call Chris W. at SOS and confirm with him. If you are planning to run at 9,000, I strongly recommend using a dual-pass radiator because your engine is going to be making a lot more heat. The Masiv is popular with the FI guys.
