Here's what I have planned, for the new setup, but also have some unknowns that still need to filled in- (btw, my goal will ultimately be a pretty reliable 400hp car on e85 eventually, maybe not until I upgrade the snail)

Basic engine:
MAP stage 1 shortblock, with the BSE kit, stock crank, just their basic build, with a few exceptions.

RODS-eagle, the ones that come with all stage one builds. I've been told they should have no problem handling 600hp

Perfect I agree

PISTONS-wiesco, and this is one spot I would like input on. The stage one build comes with the option of an 8.3:1 Manley, or a 8.5:1 wiesco. After chatting with Bob, he had suggested going with a higher compression ratio, something like a 8.8:1, 9:1, or even a 9.5:1, due to my 16g/e85 combo. He said, that I would benifit from the extra compression on the smaller turbo and on corn juice. (the planned successor to the 16g, would be a fp3052 or something similar, keep that in mind) What are your thoughts, and what compression ratio would you recommend going with?

I like the 8.5 Wiseco's. But if you plan to make big power, I worry about standard Wiseco's as I've seen lots of cracking take place in the wrist pin area.

But really at 16g power levels, a stock build is more than capable!

HEAD(1g): There will be some mild port/polish work done, as well as a valve job and some cleaning of the bowls. I discussed a possible 1mm oversized
valves, but overall don't think I would benifit too much from it, so believe I will be sticking with stock valves (chime in if you have suggestions relating to valves). Springs/retainers, may see an upgrade, but then again, a 16g doesn't have the craziest top end, and won't be revving to the moon.

I would recommend a stock 2g head, done. In my opinion, they are a superior design than the 1G design.

CAMS: The car used to have hks264's, which have been sold. I don't want to throw a ton of money at cams, so those of you using a cheaper yet effective cam, please share some insight on some possible suggestions.

I'd say find a set of used HKS 272's. They should be affordable, and you're set for quite awhile.

TURBO: A ported, externally gated 16g (for now). I have one, which is why I'm going that route, and as mentioned before, plan to go bigger down the road.

FUEL SYSTEM: This is the biggest unknown for me. I currently have a walbro 255hp, on a stock fpr. I recently aquired FIC (Bosch) 1600cc injectors (overkill, but no need to upgrade), so those will be my injectors. My question is, is there any reason to use anything more than the one 255? I've been told in the past I may need a second pump, but recently have been told otherwise. I'll be putting a AFPR on as well.

one 255 should be all you need with a 16g, even with e85. stock FPR is fine, only thing that might be affected is idle situations.

EXHAUST: Have a full 3" N1 already, and will be using a MAP recirc o2 housing, paired with a tial mvs wastegate. Plan to pick up an Fp race manifold as well.

good

TUNING: DSMlink
