As some of you may know, I'm working on that 7AGE build over in the Corolla forums. Reason I'm posting here is because I have a line on a CT-26 turbo from a neighbor's Gen 2 MR-2, in GREAT condition. For $100, it's hard to pass up. However, it IS a twin-entry turbo. I've seen custom equal-length single-entry turbo manifolds for the 7AGTE project built from a B16/B18 manifold and a 4AGE turbo flange, however given that the CT26 runs (apparently) 9 PSI stock and the engine's only been given a "that should hold up for 6-7 PSI" approval by the builder and also that it's twin-entry, is this something that I'm going to be able to bodge into place relatively easily? A couple questions:

1) Any way to decrease the boost?

2) I've heard that it 'runs out of boost' at around 5,500 RPMs...on a 2.0L engine. Will running it on a 1.8L engine let it pull up to around 7,200?

3) Twin-entry-- better to try and fabricate a twin-entry to single-entry adapter, then go with a B16/B18 manifold? Or would it be feasible to put a 4AGE flange on a 3SGTE downpipe?

4) Is there enough room in the engine compartment? =)

5) Generally, is this a good idea to try and shoehorn in or would I be better off looking for another turbo to begin with?

Thanks for your time.

because of the inexpensive price of the turbo your obviously saving $ but to build a turbo setup around that turbo might be a nightmare. that twin entry situation unless is a devided manifold will have all kiings of turbulance going into the turbo. i can tell you a million reasons why not to use that turbo. but for $100 is kinda hard to turn down. might wana use a eclipse turbo easy to get and will work best for a small hp 1.8

...Where for 'downpipe' above I mean manifold. Oops. I think the problem there, upon further consideration, is that the 3SGTE manifold wouldn't have the same exhaust port positioning that the 7AF and the 4AG head share, regardless of bolt patterning...right, the CT26 is right out.

So....did any vehicles have a Garrett T3 .50 trim (or reasonable equivalent) stock? If so, what year, make, and model would they be? A junkyard run may be in order.
