3sgte (2.2L) vs 5sfe 2.2 Options

[Random_Stranger]

Ok, I am looking at options here for upgrades and I wanted to know if there is even a difference in keeping the 5sfe 2.2 and maybe swapping the head for a 3sgte (Ofcourse turbos are going to be used) to have the 2.2L or is having a 3sgte doing the 2.2L any different? That's what I really would like to know.

I hope you're not considering this on the train of thought that 2.0 is a downgrade from 2.2. Because a stock 3S-GE or 3S-GTE will both have better power characteristics at any point in the rev range than your 5S-FE.

What your 5S-FE has gained from the extra 200cc, the 3S-GE has gained from high compression and your 3S-GTE has gained from having a very efficient quick spooling CT20b turbo which registers positive pressure from as low as 1500RPM.

No, he is strictly talking the bottom end.

The forged 2.4L 5sgte is a bit more expensive then the 2.0 or 2.2L 3sgte, but as far as motor builds go...it is isnt terrible. The only down side to the 2.4L 5sgte is that you will have to have ATS do the build, as they are the only company that I am aware of that offer this service. So since you have to have ATS do the build, you will get a motor back that is just as much plug and play to a 3sgte head, as a 3sgte bottom end would be.

And if you are putting this into your Mr2 or using anything but an AWD transmission, you wont need to spend the extra money to have the required block work done. If you are using an AWD transmission, you will need to either pay for the required block work to clear the transfer case, and the drilling and tapping of the block for 1 of the AWD support brackets.

Having a fully forged 2.4L 5sgte bottom end is as simple as dropping $3000

Hmmm... Thanks Jim, you are most helpful. I am going to research this 2.4 and look into this further... But I think I might be going this route for one of the MR2s... For the Celica, I might just stick with the 3sgte (when it comes time).
