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 Jon |

"A first major revision of the 4A-GZE was done in the 1990 model year solely for the front drive setup as MR2 gave way to the newer and larger 3S-GTE power plant. This second generation of 4A-GZE utilized the now commonly available Japanese market pump gasoline of 102 octane. Accordingly, the compression and boost was raised to produce the 165ps JIS figure. The compression was upped to 8.9:1. The newer engine also utilized the new 4A-GE block and bottom components based on the 90 and later Levin engines, comprising of stronger larger crank and rod journals as well as piston pin and used semi-forged coated pistons. The new 4A-GZE also featured the only DLI (distributor-less ignition) used on the 4A series and the AFM was replaced by the MAP system (latter probably due, more to cost of production, as MAP systems are much cheaper to manufacture)" lower compression on the earlier gen too... bonus! ![]() edit: just found this http://forums.toymods.org.au/index.php?t=m...l_view=&start=0 turbo AW11 running 20 psi on stock 4agze internals... 12.4 @ 118 mph |
