I have always loved the MR2 community for the time people take to share knowledge and make something like changing a timing belt or removing an engine seem feasible for the garage tinkerer. If you have the tools, space and know-how to remove your engine and do large maintenance items like a clutch and timing belt, this swap isn't too difficult. If you don't feel comfortable doing this yourself it would be wise to let professionals like Prime, ATS, TCS, etc. do the swap before you end up with a never-ending project.
And just a heads up, I'm not going to go into every detail here. I'm just going to cover some of the most common questions I've received through PM and address little hang ups that I encountered. I'm going to reference other sites for how-tos because I'm lazy. I'm also assuming you have the BGB for referencing torque values. I welcome additions, comments, criticism -- just post your addition or opinion on other methods for everyone's benefit.

Here is a post from Aaron at Lithia Toyota with some part numbers for maintenance items as well as a link to ToyoDIY. If you find a part number in ToyoDIY and it appears in Lithia's online parts catalog, I've found most times you can order it.

I started with a 91 Turbo. It's last state of modification was a built Gen2 project that I abandoned. I kept the LSD E153, ACT 6 puck clutch and lightweight flywheel, A2W IC and parted the rest of it out to fund the Gen4 swap. To me, the allure of this engine is that it's simply a newer model 3SGTE that gives a good bang for the buck if prices remain low. I had already sunk the expense of the intercooler, turbo kit and exhaust, so obviously those are additional expenses if you start from stock.
What I received, a 1998 ST215 with automatic 4wd transmission, engine harness and ECU. This seems to be the most common swap. It may be possible to swap cases with the FWD transmission, but I wouldn't know where to tell you to begin.
