ct-26?

[Mr2Xer]

Does the ct-26 turbo for the old supra fit in the mr2 turbo? If so, does it bolt right in? Any other information on these turbos or the installation would be greatly appreciated.

Ok, I found out that the two turbo's are different in that the Mr2's is dual entry, and the supra's in single entry. The supra's is also less restrictive and can support more hp. It also doesn't fit the Mr2's elbow. Does anyone know how to install it, or someone who makes modified elbows that would allow it to fit?

You can swap the center sections and get a small upgrade. However the Supra's exhaust housing will not bolt the the MR2 elbow.

Well aron your kinda correct. Here is my description of my install. Its not too hard to do
