Hello all. It's been a while.

I have a question concerning parts for the first gen 3S-GE and the first gen 3S-GTE. This is more out of curiosity than anything else. If this has already been posted I appologize, I did do a search but couldnt find an answer to my question.


Parts for the 3S-GE are next to non-existant in terms of aftermarket, yet there is still a market for the 3S-GTE. Will parts for a 3S-GTE fit on a 3S-GE? Things like cam timming pulleys, cams, flywheel. Or are there just enough differences to prevent these from fitting.

Like I said, this is just more for curiosity. I realize that for the parts designed for the 3S-GTE to make power on a 3S-GE the engine would have to be modified to run a turbo (including internals, fuel delivery and such). Thanks in advance.

Cheers,
Berg

Yes the parts are interchangeable as far as I know, I'm running a Gen 3 3SGE and running a AASCO 9lbs flywheel for a 3SGTE. 2nd and 3rd gen cams are interchangeable and so are the cam pulleys.

Just to back that up, I'll agree.

I've been in the same boat with the rev2 GE motor, nothing much avaliable for it.

So I bought a second hand GTE head for a play / measure up, and cams / pulleys / valves / springs / collets / retainers etc are pretty much identical.

Can't guarantee it for the rev 1 or first gen GE motors, but i reakon theres a very good chance bits will swap across :)

And also I forgot, on the rev2 the clutch size is different I think- 225 on the GE and larger on the GTE I believe, so I'm not sure the flywheel will bolt across on the rev2.

Doesnt bother me because JUN flywheels are avaliable for the GE on your ebay.com anyway B)

Thanks for the info. I always suspected that the first gen engines where very similar. I thought I read somewhere that the 3S-GTE was simply a 3S-GE with different pistons, intake and exhaust, and fuel management (obviously). I remember it saying that the second gen is when the changes (like oil squirters) appeared. This could be wrong or I could be wrong, but thats why I'm asking here. Thanks again.

Well there maybe some changes in the internals (like the oil squirters) but many of the parts should be interchangeable.

I get a spooky feeling the rods are different in length...... but dont hold me to that. I'm sure i've heard of NA's running GTE pistons so I would assume the drop in CR would be created by either the rod length or a taller block, cos if GTE pistons work in a GE then the crown to pin distance must be the same or similar.

Yup the oil squirters are ony on the GTE, and the head castings are totally different- The inlet ports are gigantic on the GTE to let as much boost through as possible I presume. Even the prettier cam cover off a GTE wont fit a GE. But as I say the valve gear all seems the same.

Again all bove refer to rev2 motors.

No no no, the pistons are different from 3SGE to 3SGTE.

Looking up the specs on the net I found that the stroke of the engines are the same so it looks like KoreanJoey is correct about the pistons being the difference. As I live in Canada, I unfortunately only get to play with the first gen motors. I believe that I now have the answers I was looking for. Thanks guys!

glad your sorted mate :)

koreanjoey> are the rods the same? if so, are the pins the same diameter? IE will GTE rods fit a GE? hope so...........

I believe so.

Yeah, thanks again guys. I don't know if this knowledge would ever be put into practice, but my curiosity is definately satisfied.
