Welcome to TN

I got you message on my Car Domain Page. I have made a post in the General Discussion section of this forum to see if I can get a list of all the Toyota Models/years that utilize the 5sfe engine.
I agree with 93TURBOMR2, the 3sgte engine is really the best alternative for you. Bolts right in. Lots of aftermarket support for this engine and it's almost bullet proof with it's iron block. 300hp is very easy to get to.
Check out the MR2 section of this forum. Lots of guys there who know the MR2 inside and out..
