3s-gte head on a 3s-fe motor Options

[samguglielmo]

Is it possible? According to the info I have read the only difference is the head. The block and internals are the same. Once again according to the numbers. Im also trying to find the right tranny to put in my 95 celica ST. Also does anyone know if a right hand car has an opposite shift pattern than left hand.

The head will work but you won't get the same performance because the compression will probably be lower. You will find a positive increase. Gonna have to change the ECU at the same time

all of these motor heads on this site and I can only get one reply.

Its been discussed MANY times, that is why no one wants to answer. Do a search on the topic

I've been here a while, and I've seen the 3sgte head discussed about being on a 5sfe block, but never on a 3sfe block. I know the 3sfe, and 5sfe engines are very similar. They'll be someone along here eventually who can answer this for you. This would be neat to do. Go buy a 3sfe out of a Camry and put a 3sgte head on it. Seems more practical to just get a 3sge, if that's what your going for. You said nothing about turbo, and this is in the NA forum, so I assume. If I were you, I might pm Kwanza. He seems to have a good knowledge of most of the engines. If he can't tell you, he'll probably be able to direct you to the right person. Check the celicatech website too. There's a bunch more innovations there than is here.

I already have a 3sfe in my celica it is a rhd from japan and they come factory with a 3sfe/4sfe motor. On this site this particular motor is not mentioned very often. I also plan to turbo this motor and and that is why I am wanting to try the 3sgte head on this motor.

I've never heard of a 4sfe. You had a right hand drive imported and it's not a 3sge or a 3sgte? Wow. Why did you do that? I'm going to half to see prove of this. It doesn't sound right at all. Easy way to check to see if it will fit or not is simply look at both head gaskets.

anyone????????????

A 3S block is a 3S block. There is no major difference between a 3SFE block and a 3SGE block besides some internal components. The head will bolt up to the block more or less, but you'll have to match up pistons...

Whats a rhd?
What kind of power bhp more with swapping the head do??
And if it doesnt give you an increase in bhp why do it?

rhd is Right Hand Drive. You can pick up some horsepower from doing this due to better design of head. The valve angles are more to the sides so it allows better flow but less effeciate burn. The 5s"f"e or 3s"f"e heads are more like signal cam than dual. It's not supposed to be that big of a gain unless your turboed, according to Kwanza. I think it would still help, it just wouldn't be worth the gain.

By the way, this is an old post. You need to do some searching on google and this site. Then you can contribute as well as ask questions.

On a 3S block you'll basically be building a 3SGE so it will be ok. On a 5S block (5SGE n/a)... waste of time due to the block's short-comings in the n/a power design.
