So I hear that you can install this v6 motor (1MZFE) into an mr2, is this true? And if so would it be a better idea to place this motor into my mr2 instead of a 3SGTE? Would I even be able to turbo the V6 motor? Any info on this would be extremely appreciated. Thanx
It's been done. I guess it's a matter of choice. There is a ton of support for the 3sgte. You can do what many have done and easily get 350rwhp dependably.The stock block and internals are good to 400hp.
Of course, there are many possibilities with the V6 too. The V6 will be VERY tight. Just changing spark plugs will be a choir.
Do a search here and you can get much more details.
I seem to recall the 3VZFE also fits and is a popular swap.
Unless you've got a specific reason to go for the V6, I'd stick with the 3S-GTE.
These swaps are usually done into mk2 MR2s. If you have a mk1, you should probably just look into the 3S.
Actually , you're correct. The 3VZFe is the swap that guys are doing. But since both are V6's generally abour the same size, the one he mentioned will probably fit-with more modifications. And yeah, the MKII. I assumed thats what he was refering to.
It is possible but will be extremely difficult, especially in a MR2 engine bay. What experience do you have with building and swapping engines?
I'd say that the 3SGTE will get you where you need to go, especially coming from the NA SW20.
If you decide to stick with the 1mzfe, it has been done before with a TRD supercharger but I don't know about turboing it, especially if you want to go twin turbo.
I think that the 1mz is a great swap for the sw20 from a 5sfe- great torque and great power band to work with. But for those that go from a 3sgte to a 1mz, I don't think that it's worth the work considering the potential of the 3sgte.
if you want to do research on the potential of the 1mz, come check out the gen3/4 camry section and also solaraguy
On my last dyno, I maxed out my injectors at 255whp- supercharged at 7psi, which, on an mr2 with headers and their damn near non-existing exhaust piping, would probably be closer to 280whp. I installed new injectors and I'm estimating around 270whp right now with stock headers

a somthing i read about the block is better on the 2.2 and head of the gte is better giving best of boh worlds really.. If i were to do that would i have to change anything else considering i want to turbo it.
You'll need to do some work with the internals and choose a compression ratio. Some 5SFE blocks need to have water passages drilled out but that's something you can do yourself. The 3S head is already set up for the turbo. It will be much more complicated than just swapping in a 3SGTE because you'll need to open the motor.
The 5S block is stronger and bigger displacement than the 3S block.
What's your budget for this swap? Are you going to be doing the work yourself or paying a shop?
What is stronger about the 5sfe block? They are both iron.. The only differences are the displacement and the 5sfe does NOT have the water jacket outlets to service the 3sgte head. But like you said, you can use the 3sgte head gasket for a template and drill them to match.
I think firing order and stroke is different.
You can really build a beast this way.
Well my brother was going to help me with the swap but hes swamped with work and his own crap so ya it looks like im gonna have to pay a pretty penny and and have a shop do it for me.. do you how much it would probably run me if I were to take out the old motor and put a 1mz in and call it a day?
I really wish i could do it myself but that aint happening
Tinkering the 5sfe seems interesting too.. you think that would be as much work as an engine swap? O and right now im not considering a budget but doing research and trying to find an estimate.
