Re: TOY: CT26 adapting to 22RTE manifold

["Michael J. Fox" <michael.fox@xxxxxxxx>]

Hey Jeff,
The motor will be getting a rebuild over the next year. I also need to get 
the CT26 rebuilt as it has some play in the shaft. The MR2 CT26 is 
different somehow and I've heard isn't as good. But I will investigate to 
see if the cast elbow that bolts to the turbo is at a better angle on the 
MR2. I know that Greddy and a few other places make downpipes for Supra 
Turbos so they might be able to supply me with a flange also.

The RTE will be out tomorrow hopefully. Hey I found a good way to get a 2" 
lift for the 4Runner, pull the automatic transmission/transfer out!!!

I know there was some debate as to whether the turbo automatic and transfer 
case were integral or could be separated. Let me be the one to tell you 
they are ALL ONE unit and really suck pulling out by yourself.

I'll keep ya posted!!
