Re: TOY: CT26 adapting to 22RTE manifold

[Jeff Moskovitz <jeff_moskovitz@xxxxxxxxxxxxx>]

Hey Mike,

So you're gonna rebuild that motor before you bolt that big turbo on, 
right? ;-)

As for fitting the CT26 to the RTE exhaust manifold: no problem there, as 
long as there's enough back space to get the nuts on the studs.

Do make sure that the oil drain port on the turbo points within 15* of 
straight down. This might require rotating the center bearing section 
relative to the intake and compressor housings, and can be a pain if 
things are good and rusted together, as they usually are.

As far as sources for downpipe flanges go, you might also want to look at 
the CT26 turbos that were used on the MR2s, as I think they point in a 
different direction. May not be a better direction, but something worth 
looking at.

These folks (http://www.roadraceengineering.com/flangesandgaskets.htm) 
sell a weldable T3 outlet flange. You might also want to ask around on 
one of the Supra sites. I'm sure *someone* makes the flange you're 
looking for.

Hope this helps,

Jeff
