This is one of those threads that I wish I had been in on earlier because there are so many wrong things to do with an mr2 that it freaks me out. Anyway, here's everything I have learned in the past 6 years...

The stock ct26 is worthless over 16psi.

The stock ct26 is worthless under 16psi.

Upgrading the ct26 is almost always worthless unless you will only ever use the car as an auto-x car and will never want more than 225rwhp. If that's your goal, then it is decent.

Clipping the turbine on a stock ct26 is worthless in all cases, and only masks an inherent fault in the design of the crappy turbine.

The stock intercooler isn't that bad, but you need to upgrade the IC pipes and put a BIG fan on it. It will heatsoak quickly, but will flow enough air for over 300rwtq. If you do buy an aftermarket IC, half of the world will tell you to buy a Greddy, and the other half will tell you to get a Spearco. I have a greddy. It's like voting for a republican or a democrat, in the end it doesn't matter, America still rocks.

Anybody who tells you to put SPAL fans in your engine lid is retarted.

As mentioned earlier, the stock mr2 fuel rail is garbage and you will need a larger fuel rail to safely make more than around 300rwhp. For now, stick with a stock fuel system and keep the boost under 16psi. If you run more, set the base timing back a few degrees, and don't sue me when you blow it up anyway.

The ct20B is the best bolt-on turbo upgrade for the mr2, and will make plenty of power. It is good for any amount of boost you can run, but if you run too much, don't sue me when you blow your engine up.

If you blow your engine up, you will blow the number 3 cylinder, and it will probablly be a timing issue amplified by a lack of fuel in the nutso tvis intake manifold.

The TD-06 is the worst bolt-on turbo upgrade since you need to spend $3000 on the kit and an external wastegate just to make it control boost wihout spiking. Then a guy with a $600 t3/t4 will drive past you anyway.

The 1991 tranny is garbage, but if you treat it right and put some good redline tranny fluid it might last, but don't count on it.

The mr2 is an amazing car, but before you spend a dollar, find out exactly what you want the car to do, and focus exactly on that. You can spend $3000 to make 290rwhp, and $9000 to make 305rwhp. How bad do you ned 15 rwhp?

My comments will anger some...I apologize, but I've made most of those mistakes, so I learn from them.
