can i put a 3sgte head into my 5sfe? im going to turbo it in may but i need to get the motor in better shape and need lots of new parts.

It's not a direct bolt up. It's possible with the right amount of money and fabrication. The 3sgte head is a 2.0l where the 5sfe is 2.2

you sure as hell can.

i started reading the link but got tired due to the numerous pages. i saw that ice said it should be a plug and play. is that the case or am i going to have to get it fabricated to fit?

its called a 5sgte. its not cheap or easy to do and you would need to invest a lot of money into it.

Yea... Ice put in over $20k US and is still having some issues with it.... It looks like a cool project though, and I have no doubt that his car will be kickin ass when its finished.

If you got tired from just reading about putting the GE head on a 5S block, then i wouldn't recommend you doing it haha.

if you do it right it can be a good project.... RACEENG.COM sells the pistons & rods set for the 5sGTE $$$ but without tuning you just get alot of more TRQ...

You can get more than enough hp out of your 5sfe with just the turbo. Have the 5sfe rebuilt, then slap the turbo on thier. It'll be fast enough to outrun most anything on the street like that. Just check some posts about turboing the 5sfe and see what people have done to get good numbers. btw, anything over 300hp in a FWD car (especially without LSD) is going to be more of a pain to drive than pleasure in most cases.

MR2OC thread titled How to put a 3SGTE head on a 5SFE block: http://www.mr2oc.com/showthread.php?t=864

First off Why!? Easy, the 5S block is actually stronger than the 3S, who woulda thunk it!

It says that some 5SFE blocks will bolt up to a 3SGTE head without problems, mostly 93+ 5SFE blocks, and you can tell if your block will bolt up to the head by getting the head gasket for your generations 3SGTE head and lay it on your 5SFE block, if all the holes line up right, you're in business if not well...
But if you drill out the coolant passages(About $200 USD if you take it to a machine shop) so they line up(this is common 5SGE practice)then you're back in business again

Seems like everyone over at MR2OC says once you have determined if/made your block will/to work you will need new pistons to bring up the compression ratio with pistons that are .5mm to big requiring you to bore out your block because with stock 5SFE pistons and the 3SGTE head you'll end up with a compression ratio of 8.65 to 1, now here's what I don't get, the 3SGTE has a stock CR of 8.5 to 1 so WHY do you need new pistons for a higher compression ratio if it's already higher than stock!? If the CR is low you can boost THAT much MORE, people pay big money for Low CR pistons, I just Don't Understand this logic, anyone else care to explain!?

Then after you have your head hooked up you can start bolting on all the manifolds and such you gotta decide about Engine Management. You can choose to go full EMS, a piggyback w/ 3SGTE ECU, or if you plan on running stock levels of boost(for a 3SGTE) you can actually just use the just the 3SGTE ECU because(according to MR2OC)the stock ECU is able to do all the calculations and can adjust itself for the extra .2L of displacement even if it dosen't know they exist.

a 5sge (the "g" and "f" are the head codes) is a nice thought, the heads do flow more air, but then u need to get better cams. and since there r no 5sfe cams out there that might be hard 2 do. the 5sfe is a much stronger block, its a one piece cast iron block, as the 3s is aluminum. but as stated b4 the 5s with boots is much better, the 5s already makes plenty of low ean TQ, just keep the 5s heads and boots around 6psi, any more and u will need 2 make fuel mods. i mean the 5s 6psi set up is good for around 250 hp and TQ. and u can turbo a 5s with only spending $1000 or so without tuning.

First off, there is NO such thing as a aluminum block 3S. Period.

Second, C:R differs depending which gen you get. 1st/3rd are 8.5:1. 2nd and I believe 4th are 8.8:1.
In the thread referenced, he's talking about raising C:R for a NA application, NOT turbo....

Third, while the 3rd gen 3SGTE has some early block problems, the 2nd gen and late 3rd gen blocks are no weaker than the 5SFE....
The main reason the 5S block is used is for the relatively large jump in displacement. More displ = more to spin the turbo, all others being equal.

Fourth, the stock 3SGTE cams are just fine for flow on the stock head.
Nothing wrong with getting better ones, but you don't "need to get better cams".

I don't know how comfortable I'd be spinning the 5S bottom end at stock rod:stroke, even with aftermarket rods [FYI the stock rods are forged, as are the stock pistons, at least on most 5S. The really early 5S might not be, but probably are.]. I'm sure others have done it, but I would rather get custom rods/pistons to address this if I was going to use the 3SGTE redline.

Honestly, if you are going to stick with less than say 300 hp for now, I would just turbo your 5SFE. At low levels the 5S actually has more overall potential than the 3S, assuming it's healthy. More displacement, higher C:R and a better torque curve make it that way.

thanks for all the info. i decided im just going to rebuild then engine colpletely and just boost it.
