First I want to acknowledge that my cams and caps are amazingly carmelized. I took them to work and ran them all through the parts washer but that didn't help matters at all. I'm going to have to take them to a machine shop and have them hot tanked to get them clean I suspect. I need to get the valve covers dipped too so I'll take them all in at once after I have the shim numbers.

Components needed are:

I refuse to believe that an MR2 doesn't want to be driven hard so I'm going to run with the theory that it's hungry for more ponies. After careful consideration I decided to attempt to sate it's hunger with a 1mz swap.
Now because of the fact that I've had 2 engines fail on me I knew I was going to need either a crate motor or one that
