3sgte head on 2.2 - Toyota Nation Forum : Toyota Car and Truck Forums

could i put the 3sgte head on the 2.2 block and keep it all motor. i have been told the "g" heads flow a lot better. what kind of performance gains could i expect from doing this. or should i get the 3sgte head and turbo my engine. any input and info would be greatly appreciated

my car is a 1991 mr2

Pardon my ignorance, but I thought the 91 MR2 was a 3SGTE which means it IS turboed. Did that generation come with anything else?

it is a 1991 mr2 with the 5sfe which is a non turbo 2.2 liter

I'm not sure if you can lose the 't' in the 3sgte.... you might have better luck using the head of a 3sge? Or just doing a beams 3sge swap if you can find one.

the 3s-gte head flows more, but has cams setup for a turbo motor (low lift and duration, small overlap, I believe...). You could try a 3s-ge head instead. You will need standalone engine management or something to run they hybrid motor... so good luck!

I vote that you just do a turbo or a swap. (not that either of those is easy... but both have been done before)

I'll be darned. I never knew there was any option but the 3SGTE in the MR2. Hmm.
I haven't seen the 3SGE heads, but I wouldn't run the 3SGTE head without a turbo, they are friggin huge ports. Terrible velocity in a NA application. I think the turbo manifold will bolt onto the 5SFE head though, if you go that route.

Welcome to the board, this question has been asked a bunch of times, try doing a search for 5SGTE or 5SGE and you'll find some very good answers.
