3s head

[gtpornstar]

Hey guys
Just wanted to know if a head from a 3sge is the same as a head from a 3sgte, understand it depends on which car for the intake and exhaust pleniums but are the heads themselves different ?

Got a head from a 3sgte 1990 toyota celica gt4 that has blown and looking to replace it, had over heated and the head guy looked at it and then said it had become too soft to plain etc.

Try PMing Adydas he was investigating this recently viewtopic.php?t=68723&highlight=

I still really want to know this myself, i have photos of my 3sge so if you photo this naffed 3sgte perhaps we could work this out together?

i used a 3sgte headgasget ( ok it blew and i still dont know why and thats why im asking the same question ) but it fits so the layout is about the same for cutouts, oil galliers etc..

bah i needed to reuse the old intake and exhaust manifolds so looks like a no go for me.

i would think itd be pretty unusual for toyota to change a head casting just coz they go turbo
having said that they use rather different heads on the manual and turbo altezza beams engine

[Eddy1612]

they are definitely different mate. ports are different.

If you try using other heads i.e similar heads or non turbo heads etc etc it will limit you on boost later etc

I have been through this man. Best thing to do is ring around the parts importers around nz. 3sgte heads are hard to find in good condition cos they all go soft.

MAKE SURE YOU GET THE HEAD TESTED BEFORE YOU BUY IT!!!


I checked numerous heads from wreckers before i actually found one that was fine which took my like a month to find!

i bought my head from a guy in Rotorua. i found him cos he had a 3sgte engine on trademe so i rang him up and asked if he had some heads. Luckly he did.

hopefully this helps
pm if you got more questions

I'd say '89-'92 MR2 & Celica 3SGE and 3SGTE heads would be different as the 3SGTE still uses T-VIS but when you consider that adydas uses both ST205 intake and exhaust manifolds on his ST202 3SGE then surely they'd be the same except for minute differences in cam profiles.

[Mr Revhead]

from my explorations on the EPC im fairly sure all the changes were date changes? and the only difference between turbo and non turbo was pistons...

but im not sure enough of my memory to say im definitely right! i AM sure the rods and cranks are the same

[gtpornstar]

i just need to get the car going for now, it wont see a lot of boost so dont mind if the intake or exhaust valve is smaller etc. Mechanic is getting impatient with me hehe

Mr Revhead - so any 1990 celica head would do the job ?
What year was the st185 shape ?

[Mr Revhead]

i THINK so. but i am not 100% sure

[MR2SIK]

speaking of ge vs gte heads, would cams from a ge fit a gte? I know someone who has some pretty aggressive cams out of a decently powered 3sge, and im able to get them for dirt cheap. If theyre compatible

[strx7]

yip they'll fit. The opening and closing timing might not be IDEAL for a turbo'd car but give them a whirl and see how they go. If you have some kinda of aftermarket ecu that is, if its still on std ecu i would pass.

I don't think they are the same, GTE engines of that generation had big ports and used TVIS. IIRC GE was a small port engine and didn't have T-VIS.

Gen III's shared the basic head design between GE & GTE but not Gen II.

true, hmm ok cool. Have to keep hunting for a head.

St185 was '89-'93 so if your car is an ST205 then these heads are NOT interchangeable.
Being a 1994 You will need a head from an ST202 SSII 3SGE Celica if you cannot find a genuine ST205 cylinder head.
ST202's pop up at pick a part so you might even find one there.

whoops sorry was thinking my supra, the celica is a 91 or 92 i think the st185 shape.
would you know if a non turbo head from the same shape would bolt up to the block and manifolds ?

[Twolitre]

Ahh ok I see that you have edited your initial post, in that case unfortunately you're pretty much stuck to finding another ST185 or same year SW20 3SGTE head.

Yeah I did.
so a 1990 toyota celica non turbo 3sge head will not work right ?

[Twolitre]

No, because the ports are different
