I know exactly how to do it, like I said I don't have the money right now for the short block. I had an rx7 fd for 9years and did just about anything you could do to an fd by myself, so I do know what I doing, but yeah if someone could donate an engine please be my guest!

Phil,
I'm not sure how you would make everything work on the electrical end of things. But to get the engine to drop in, you'd probably have to use a renisis end plate if thats where the engine mount holes are. I haven't seen what a bare renisis block looks like so it's hard to say...I'm still a noob to the 8 world
