That looks from the pictures to be the precision "dsm bolt on" turbine housing. Same housing that Buschur Racing's original turbokit had. I ran BR's manifold with a GT35R using the turbine housing pictured there. It was decent.
But it is absolutly 'NOT BOLT ON for the stock EVO8 manifold. ATP is the only company offering a bolt on garret turbo that uses the stock evo8 manifold.

worst case scenario: Just the turbo kit no aftermarket exhaust, stock cat, stock displacement. Full spool @ around 5500 rpms
My scenario: Full 3" Turbo back, no cat, 272 cams tuned for better spool up rather than higher top end. Full spool @ around 4600~4700 rpm

There are not very many bolt on turbo's for the evo because the evo is a reverse rotation setup.
As far as I know, you have the ATP turbos that have their proprietary turbine housings, then you have FP white rabbit, BR 20g, the TME.....and I think that just about covers it. Others have tried to make their own bolt on turbo (including a local turbo company here in town) with marginal results.
The problem lies with the reverse rotation, if this was a DSM there would be a ton of options.

Yes the stock turbo is a reverse rotation turbo, but the exhaust gases coming out of the exhaust manifold has no foward or reverse or as a matter of fact any rotation. The fact that your local turbo company had maginal results could be from many other factors such as improper housing design, wrong turbo sizing, and so on....
Also, DSM has been on the market for ALOT longer than Evo's have. So that 1 reason why there are more options for DSMs

The statement that you made " The problem lies with the reverse rotation " isn't quite right.

Couple this with the fact that the stock turbo is VERY efficient all around, and you have something that really needs no improvement.
Yes. I do argee that the stock turbo is efficient with-in the stock power range, but there are rooms for improvment.
What do you consider "any type of power worth the money"? I dynoed 228 whp on a dynojet AWD dyno on 91 oct when the car was stock. After the GT35R kit, injectors, SAFC, and 255 fuel pump I dynoed 372 WHP on the same dyno.
GT35R kit = $2500
injectors = $400
SAFC = $300
255 pump = $95
to the total is $3295
total whp gain is 144whp
That's like $22.18 per hp and this is on 91 oct. So for $3300 I gained 144whp doesn't seem so bad. And on race gas I gained 220WHP I think it's totally worth it.

one of the very few company's that make a 35R thats bolt on for evo's is ATP also you have to buy the down pipe. it cost around 1500 to 1750 depends where you get it from.

372whp on a dynojet with a 35R is kinda weak. car should be making well over 400whp. The atp kits are nice because they bolt to the stock manifold but they flow horrible and really arent that great when used with a 35r. The sharp bend and bottleneck of the ATP housing makes it not worth buying In my opinion.
O and the fact that the evo is reverse rotation is exactly why no turbos are made to be bolt on. the position of the exhaust housing in reference to the manifold is opposite of 99% of the turbos in existence so you need a manifold that emits gasses closer to the block so the offset part of the housing can be towards the front of the car
