I'm with LokiRx7 on this one, the 4A-GZE would be a much better choice than a B18, just from a practicality standpoint. It'll go in with minimal modification--whereas a Honda would have to go in the engine bay backwards because the engine turns opposite direction. This means a Honda engine will need lots of fabrication--everything from the motor mounts to the axle shafts will have to be custom, to the extent it would probably be easier to weld the Honda's front suspension into the back of the MR2. I will say, the B18 is a lighter engine (148.1kg vs. 155kg 4age)--though I doubt if your car will still be lighter after all the fabrication you'll have to do. Also, if you can find a way to make the shift linkage work you've probably earned an honorary engineering degree. You know, now that I think about it--it would probably be easier to rework a B18 to spin clockwise than to re-orient the transmission and re-engineer the drivetrain. Might be issues with keeping the timing belt on, but I bet its been done.

I don't have any problem with Hondas, my other car is an Integra with a B18, and I'm very fond of it. It would easily beat my AW11 off the line, (it's got so much more torque at 1,000 rpms, it's not even funny) but my Two catches back up pretty quickly. Speedometers indicate the Integra has a higher top speed, but I've never buried the needle on either one of 'em.
