GE head on FE internals - Toyota Nation Forum : Toyota Car and Truck Forums

djprefix · 07-06-2003, 02:45 PM

Hey, I was just wondering if it was possible to throw a 3sgte head onto a stock 3sfe short block. I heard the valves will hit the pistons due to the 50 degree valve angle opposed to the 22. Can anyone reliable get some confirmation on this?

Hotwheelharmer · 07-06-2003, 05:51 PM

No they wont hit the valves since the piston design is almost the same on both engines. And the valves are not 50 degrees in a G head they are 45.

Is there any reason why you cannot put GE head or cam on FE block?
And would it bring/lower torgue at any rpm? What things should be noticed in change?

Offtopic: Would 5S-FE pistons fit to 3S-FE, I would like to have 2.2l
3S-FE or 2.2l 3S-GE, or should i change crank or something?

Sorry about bad grammar. And thanks for the answers

ya, I am vary intrested in this too

Well if you want a 2.2L just get a 5sfe because that is what it is. That is the only difference on the 3sfe and 5sfe for the bottom end. The 3sfe has a 3.39" bore and stroke and the 5sfe has a 3.57" stroke and a 3.43" bore. You can either get the kit from Jun or somebody like that that makes a stroker kit for the 3sgte and drop it in but that is very pricey and hard to get. You can also put the 5sfe crank and rods and get custom pistons for you for the stoke bore or 20 over to give to about a 2.1L. As for the G head replacing an F head. It isn't as easy as just taking one head off and putting another one on. If you have a 3sfe you have to make sure you have the other parts from the engine like the intake manifold, wiring harness, all the sensors, throttle body, distributer and you don't have to change your bottom end internals but I highly recommend doing this anyways. As for putting a G head on a 5sfe block you have to get some machine work done if the block is 94 or newer. If the block is 93 or older I beleive it is a direct bolt in and again you have to have everything else as well. The only real way this stuff works is if you are willing to spend a lot of money and have a lot of devotion to it. If you don't have either of those just stick with what you have.

Yea, I plan on doing something different. Since there's no sensors in the intake manifold I'm plan on putting on a 3sgte head and intake manifold, then making an adapter for the 3sfe throttle body to fit onto the 3sgte intake manifold. I need to find out about fuel injectors though. Anyone have a pic of the 3sgte injector/intake manifold setup, like where the injectors mount into?

Yea you can put a GE head on an FE block. But the FE head is built for low end torque. The GE head is higher revving and will have more hp though.

Hotwheelharmer · 07-07-2003, 07:04 AM

Why the hell would you want to put the 3sfe throttle body on that. Why make things harder then they already. Just get the throttle body that came with the intake manifold and get the wiring harness for the G head. If you are putting on a G head you can't get around using the G head wiring harness. The F head computer wont read it right and will make the engine run like shit so just do the easy thing and get the wiring harness. Don't make things harder then they already are because you have already done that with a lot of other things.

One friend of mine said that his friend said, who is working for local Toyota dealer, that the only difference between 3S-FE and 3S-GE is cam. Will it make any difference, that we dont have EGR stuff etc here (-90/91) and allready have 128hp (94kW) in Camrys?

Btw..will 5S-FE fit in gen2 Camry? Sparesparts book says that there are 2.2l gen2. There are one in Finland. I haven't heard anything like that before. You just have to believe it.

Actually your friend is wrong. There is a lot more different then just the cams on a 3sfe and 3sge. The 3sge head has a lot better flow in the ports, has the valves in the combustion chamber at 45 degrees, the intake manifold is designed differently, the cams are true DOHC and the valves springs and lifter buckets are bigger. The 3sfe head has two cams with scissor gears in it, valves in the combustion chamber at 22 degrees, the flow sucks on the ports. As for the bottom end the 3sge has stronger material then the 3sfe but they are the same length and everything. As for a 5sfe in a 2nd gen I have never heard of it but they may have put a 5sfe in them outside of the us and canada. In the US and Canada they only came with the 3sfe or the 2vzfe. It will fit however since the motor mounts should be the same.

damn i knew that

Eqoistig · 07-09-2003, 12:43 AM

What about using FE cams but GE head? Littlebit low torque and better flow?

You can't change cams between heads.

Eqoistig · 07-09-2003, 07:02 AM

Why not? Not even with modifying? What should I do to 3S-FE if I want more HP&torqu? Nothing radical I mean? Turboing is not possible, it's too hard and expensive here. Can I do anything for engine, without re-chipping it?

Or if I change engine to 3S-GE, what could I do to increase low rpm torque?

Hotwheelharmer · 07-09-2003, 07:18 AM

Well as for the cams I don't know why you would want to put F cams in a G head because that would just screw up what you have. The torque from the F heads are built from the long intake runners and the flow of the heads very little of the torque for an F head ceoms from the cams. Infact a G head has bigger cams. As for getting more torque and horsepower really all you can do to notice a good amount of gain is to do more then the usual intake and exhaust stuff. If you want some good power I can build you a head if you want. You could gain up to 40-50 hp from the head I build depending on how much you are willing to spend. That is the story for anything cars "How fast you want to go depends on how much you are willing to spend." Just remember that when you think something is too much.
