4agze+turbo, = muchos grande hp Options

[FallenHero]

Let me through this out here: I've been thinking of findind an old 88-90 MR-2 with a 4agze. I want to do this to get the engine at LOW cost. I was thinking of re-building the engine with forged pistons and a JUN crankshaft. I would re-build the head, but I don't really see much of a need for major upgrades to it other than adjustable cam gears. (maybe cam shafts, but as far as porting goes, there isn't a place around here that could do it, so.... I'm rather limited.)

I plan to turbo it. I'd like to get the engine bullit proof if you get my drift. I'd heard it'd be better to build a 20v for a turbo application, but I would think a built early model 4agze would work just as well, and cost FAR less, especially if built properly.

Also, I've been reading up on assorted turbos, and was wondering if you guys could go over differences in turbo size, compressor size, etc. What is ideal for our smaller toyota engines? Also, I've seen many CT-26 turbos floating around, and was wondering where I would look for a re-build kit to make them worth while. I've been wearing e-bay out looking at turbos. All I see is T-4 this, and t-3 that. Sometimes TO-4 and t-3\t-4. I'm a bit confused on that part. Any input would be appreciated. Thanks
