Treadstone IS300 manifold 2jz-GE
Anyone else using the Treadstone GE manifold? I'm just wondering what the biggest turbo housings that will fit without touching the shock tower people have used is?
Was thinking of going s369, but borgs have massive housings. The way the turbo would sit I have a bad feeling that there is no chance it would fit.

I'm running it with a ebay copy of a TD06/25G, this a 4" inlet 2.5 out compressor housing and it has MAYBE 1/4" clearance cold side. This is similar to a GT35, almost 60mm inducer.
I think people who dream of running a big turbo and a spool valve with this like the GTE guys are going to have a nightmare.
The waste placement serves only to allow the crossover intake, and forces some tight restrictive bends with little room for a flex section if you want to reintegrate right at the downpipe. With my 4 inch ebay supra downpipe/midpipe i had to extensively modified to use with the Treadstone, it didnt leave room to exit with that 4" pipe, so gentle s-bend screamer pipe for now dumping right in front of where the downpipe meets midpipe.
Bottom line after all the hassle of grinding the mounting holes just to get it to bolt up, and having no option but to custom make ALL pipe work hot AND cold because of the manifold, i cant really recommend it.
I wish i had just swapped a GTE head on it, could have had off the shelf CHEAP options, minor modifications AND a path to big hp later. This manifold is best suited for sub 500hp setups, but is a hard way there.
It is quiet, shouldn't crack and does for better or worst have a oem look. I was happy that the radiated heat was MUCH less with the lower surface area than a tubular design and as i said much smoother sounding, hearing only intake and turbo it sounds like a jet getting ready for take off at spool and them whoosh!

This guy has a PT6266 right up against the shock tower so I guess that's the max you can go with this manifold.

So the 6870 uses the same housing for PT. If it's the SP cover. The 7675 come in a H cover which is 3" but so do all the smaller turbos. I guess the question now does a H cover fit or not. I know the SP does for sure which is what I'm guessing is on that 6262

I have a 6266 its tight, the 6466 has the same body as the 6266. I doubt the 6870 will fit on the tread stone. I believe 6466 is going to be the highest HP turbo for the GE treadstone manifold and not touch the shock tower.
