Really just chasing my goal for the car which is killer torque to pull out of corner. Its a hard balance to find on a small motor. Hoping I am narrowing in having done the 35 then 28 now essentially a twinscroll 30. I can play with AR ratios to dial it in. I think I want to set a goal of 400 ft lbs. Crossing 500hp would be nice too, that would come first.

This kinda sounds like you need a variable turbo .. I know some newer 911's have those but they do present a challenge to tune and setup. I would imagine that'll give you great torque too.

Just my 2 cents

4 separate turbos, I don't know how many feet of intercooler piping and different stages of fuel ... and I'm over here trying to decide what color my center plaque will be.

This is some pretty insane fab work buddy!

Not sure how it would work on this platform but how about a quick spool valve?
I see a lot of supra guys having good experiences and showing good gains.

Quick Spool Valve are a curiosity for sure, little pricey for experiments. Then again that would skip the need for a second wastegate, kinda balance out there, mhmmmmm....

Fantastic build page! Love all the pics and beautiful fabrication. Keep up the great work!

Got around to making a manifold with the new Billet Tial V-band merge collector, still lots to do but at least it looks like something.

I hope I can inspire more people to follow suit. I'm only say 6 yrs into fabbing my own stuff, I learn something new every part. My first part was an up pipe for my STI.

love it. I have been self-fabbing for over 10 years, as much as i can. I totally over-utilize my machine shop at work lol. Can't talk my new boss into getting a TIG, (new job, my old job i had all the things!).
