I've already got all the boring stuff out of the way. Forged pistons/rods, BE oil pump, CSF radiator, coolant reroute, arp heads/mains, high flow fuel rail, brakes, wheels, tires, tapped oil pan, even fun aero bits, etc.. I'm looking at going big. (400whpish)
My shopping list for turbo parts sits as this:
BW6258 (still undecided)
Probably sticking with a fm/begi mani (still undecided)
Custom downpipe/exhaust by my exhaust shop
ID1000 Injectors
Walbro 255LPH-HP Fuel Pump
MS3x by Braineack
SS water and oil lines
Fab9 Stage 2 Intercooler
TS Kompact BOV
LS2 Coils
DIY Catch can
Various gauges such as AFR, water and oil temps, and boost.
Probably forgetting some things.
What do you guys think about this lil' list? What would you change? Upgrade parts? Downgrade Parts? I think I've got it pretty well planned, just want some voices on it.
First engine build for me (still in highschool), so bear with me.

Intercooler and piping, just do yourself and buy a Precision 600hp.
TSE 6758 is your only real option if you're going to be doing this nowadays.
Basically.....

You're going to eat 6 speed transmissions like some tasty banana nut bread.

Really interested in the TSE setup. Sav, any idea when the intercooler and piping will be included in the kit? Also, with this kind of power I would imagine 5-speeds would break every month or so. Would you guys recommend going 6-speed or rx-7 conversion, or something else?
5-speeds behind a 300+whp car will last about as long as a Kardashian marriage. At 400whp you may not even get off the dyno with it. We are working on a T5 swap right now that will handle the power, so for now, get a 6-speed and be nice to it.
For 400whp, you need the 6758. It's not quite as crisp and smooth as the 6258, but it's leagues better than any other turbo capable of making the power. The 6758 feels similar to a GT2860RS with better transient response above 3500rpm.

6-speed and be nice to it sounds good for now. All in all sounds like it will be about $5000 or so; give or take. Already $7000 into it making it as bulletproof as i can. Just spent $500 on paint a few minutes ago. Definitely a fantastic financial decision for an 18 year old.
I don't think I'm overlooking anything. I hope not.

I think 400 might be possible on the 6258, but you're gonna have to run ALLOFIT and the rest of your setup better be tip top.
I don't know if you drove/rode in a true 400whp BP Turbo Miata, but many people don't even understand how violent and ridiculous it is. There's a reason there are so few of them out there.
