Nah, RHD is not only for mailmen, but for adventurous people as well.

I would seriously research the topic of Supras that swapped in built 3sgte's and see how they attained their high horsepower levels.

Also, be sure to check out some of the MR2 forums, because some people on there have high horsepower figures as well.

The AWD setup between the 205 and 185 are basically identical. You would need the 205's drive shaft to have the correct lenght, but the 205/185 rear diff assembly is identical. The ST185 and 205 trans are also interchangeable. The gear ratio's are different though so you'd want to decide which is more appealing to you. The 205's trans is slightly stronger with dual and triple syncro's.

Then for the 205 engine - block's are basically the same (though the 205 has an oil filter relocator and slightly lower compression). For 500+ HP, the stock pistons will need to be swapped anyways.

The 205 head is where the power is - better flow design from the throttle body through the exhaust. The 205's TB is 3" and the 185's is 2". BUT - if your looking for 500+ HP, neither will be good enough in its stock format. A Trueleo intake manifold, larger valves and ported / polished head will be a must. With that, it wont matter which head you use!

And when looking for that type of power, the stock ECU's wont cut it, so you'll need a standalone EMS. The stock fuel injectors wont be ale to flow enough either, and the stock CT20B turbo is only good for 300HP (the CT26 is only good for around 260).

So, in reality it doesn't matter which motor you use, because you'll be replacing most of it anyways!
