Don't know, but I just wanted to comment to show my respect for an 85 Celica. A friend had one that generation, absolute blast to drive.

There's a resto-mod place in Ava called Gary Rod and Chassis that specializes in 70's and 80's Japanese sports cars. They do some neat builds. They've got a facebook page.

Can't think it would be too bad to rebuild a Toyota engine of that era.
