Help! Cams, heads, boost and a million questions in my head

Agreed on the Aero 340 (e85 ready out of the box) 1000cc injectors and return. Hit up Charles (CJM) and he'll take care of you, both in terms of product and professional advice. Great guy to deal with.

If you're doing all that it is probably worthwhile to just go with his hat. In which case a Walbro 485 will future-proof you even more. It's only like $20 more, but it is big so don't plan on using it without the CJ hat unless you want to carve your OEM basket assembly like a thanksgiving turkey.

The new ID1050 are e85 compatible as well.

Inline filter and possibly regular would be necessary at that point.

I skipped the hat and stuck with Aero 340 but I'm shooting for 500whp not 600. In the middle of my tune right now so will have a better idea of my duty cycles in the coming week or so once the weathers martens up.

You're probably going to be running 2.75" piping with the turbo setup so 70mm throttle bodies would match up perfectly. I've considered going to a 3" charge pipe and 75mm TBs but going to play that by ear for now.

Are those headers long tube, or you need a down pipe with them as well? What's your current exhaust setup.

A lot of the K plus guys aren't running larger displacements, or rather they were and went back down to 3.7 (or 3.8 respectively for GTRs). The reasoning for this however I don't recall offhand.
