I wanted to post this separate from the other H1C threads so as to not hijack.
I found a fella on ebay who is selling NEW H1C turbo's - I had him look at the exhaust size housing, and verify that it had the smaller (compressor?) housing - it does, a 12 is stamped on the inside, so I assume that it is indeed the preferred 12cm2 for our engines as has been documented on this site.
I went ahead and placed the order, $300 later it shows up on my doorstep. When I opened the package, the exhaust side appears correct, but the intake side - where the air filter would be attached - is only 2.25 OD instead of the 3.00 like what came on my 4BT. I wasn't aware, and didn't think to ask about the front side of these.
After reviewing the H1C rebuild thread - it looks like I might be able to disassemble the intake housing of both and swap my old housing onto the new turbo. Does anyone know if the internals are all the same on the H1C turbos?
If anyone knows how to interpret the data plate info on the Holsets;
