Got my 2 bold manifold and swapped it on to the mock up engine. It is exactly the same flange height as the 3 bolt 152T manifold. It will have the rear bolt in a difficult location so I'll use a stud threaded into the flange and a nut up above if it is a problem. Pix of course.

Does anybody know if a oem turbocharged 152 was stamped with a “T” in its ID pad, EG 152T instead of 152E or 152A?

For some reason I have one left-over, fubar 152T compressor housing and it still has that little ID plate on it. Is what you are looking for on that plate or perhaps cast onto the housing's surface?

How does the overall diameter of that T25 compressor (or exhaust) housing(s) compare to the original TRW turbo? Smaller, I imagine?

I was referring to the engine block pad where they also stamp the SN of the engine. I think the mock-up was once a 152T from the parts on it. The block is stamped 152E.

This GT turbo is smaller but will flow enough for 270 hp but has smaller in and out diameters than the OEM unit.

Sorry I misinterpreted your question. It's a good one - like to know the answer to that myself. I'd post this on the BB. There are a couple of people that still having running 152Ts.

Still mulling over the location for the turbo. I have sourced another GT turbo with journal bearings and no water required. It has better turbine flow capacity and still will support 250 hp. It is the gt2252.
Still however mounting it low like I have photographed has some drawbacks:
1) Being low exposes the turbo to water and other objects.
2) Tucking it in close to the block for space, will create some plumbing issues. The OEM manifold to turbo inlet is a tough angle. While doable, I will end up with having to preassemble the turbo and manifold prior to installing on to the engine. As well as requiring that the oil drain be plumbed into the pan with little drop.

I'll break out my 152 T exhaust manifold spacer (sorry Mark) and mount the manifold pointing up for mocking purposes. I wonder how bad repoping the spacer would be? probably SS or steel billet . Or find an extra one. If there are any members willing to part with one PM me.

I'll tinker with the options and see what makes the most sense.
