3SGTE Head

[Chose]

I was told somewhere that I can swap my 5SFE head for a 3SGTE head. Is that true? If so how much work am I lookin at, custom fabrication n crap?

I think you can swap the whole motor out and it will work with your 5SFE tranny, as for the heads alone... I doubt it, but I know little to nothing about either engine so maybe you can ask around on celica and MR2 forums etc. and see what's up.

5s block is not rev happy like 3s block...something about us having longer strokes than a 3s version one. from my celica knowledge: mating a stock 3SG head to a stock 5S bottom end will hurt compression because of the differences between the combustion chambers of the different heads and also cus of the piston design. you gain torque, but loose hp! so in other words not an easy swap..but is it worth it? some claim high revs are attainable, but to what extent are willing to test this yourself to see if compressions is ok..your call. I'd rather not if i were you!

At Toyotanation, theres been some heavy discussion about the 5SFE to 3SGTE Engine swaps. Only thing I can so far to understand though, its the whole engine and all the components plus using a MR2 transmission thats been converted for FF driving.

There's tons of talk about this at www.mr2oc.com

it will cost you alot of money because the 5sfe you have is very different from the mr2. few things will fit and few thing will not. i think you will also need to buy a stand alone ecu to operate this setup, which will cost you about 1500-2000 dollars and intensively tuning and headaches.

to directly drop in a 3sgte will be a better solution
