Now that I got 398 running well in mostly stock form, the next thought is of course more power. My target is 375-400 whp on pump gas over the next 2 years or so; nothing mind blowing but enough to get your attention. I intend this to be a DDable, and a weekend toy for track events and maybe some rallycross. I don't foresee drag racing in my future. I started reading How to Build Max-Performance Mitsubishi 4g63t Engines by RRE (although now I can't find the darn thing), and then I realized that book is over 10 years old! I've also been reading different threads which give good ideas, but not the end all be all and they rarely follow up with results.
Right now she sits mostly stock with notable upgrades being a small 16g turbo, rewired walbro 190hp, K&N, 2.25" exhaust, Greddy EBC.
The goal is acquire quality pieces as they become available at a decent price. Not trying to go bargain basement, and not trying to pay f' me prices to get it done tomorrow.
So I have two questions. Is my build sheet reasonable, and where do I start?
The Plan (since I have a block that needs to be machined anyways):
EMCLink - 600
At least a 4 bolt rear diff
3" exhaust
FMIC - EVO XIII/IX - 150-200+/-
3G MAF
2.3L with 9:1 compression
4g64 crank - 200
pistons - 600
con rods -
Cams - I was looking at 272/272 cams but don't know with larger displacement
850-1050cc Injectors
16/20g hybrid turbo
Tranny rebuild
My upgrade path will likely be in this order, as the first part of the list I can use with mildly upgraded motor in there now. I can do the latter part of the list with the block that's out of the car right now. I do live in CA, so smog is a thing. Attention, either from LEO's or others, is to be avoided.
Advice, hints, tricks, tips, and leads are all welcome. I am updating my build list with model/generation notes and approximate costs.
