not many people bothered turboing a 3s-ge just because it was easyer, more cost effective to just drop in a 3S-GTE
the 3s-ge doesnt really have as strong of internals compared to the 3s-gte so you cant really boost it that much.
do some search's but you'll be lucky to find if anyone has done this conversion

the only differences are as follows gen and 2 na have no oil squirters ,but the gen 3 does and the comp is higher as well compared to the turbo version and they all have steel cranks ,and from gen 3 the blocks did change mainly in the turbo blocks as in stronger

I have thought about it, could run a very tidy setup I reckon, a few of the SR20DE guys have done SR20DE+T conversions, with awesome results. I think it would be a fair bit cheaper for people who dont have the skills to do a full conversion(I know I sure as hell dont).

The 3sge has same crank and rods from memory, im more after what sort of results people have had performance wise? Im not doing your run of the mill celica fwd conversion, this is a rwd format.

My Gen2 3SGE does NOT have oil squirters - I plan to fit them, but as it sits right now, it does NOT have oil squirters...
GTE intake ports are bigger than GE intake ports, and should have better static flow on a flow bench, but that doesn't necessarily imply better cylinder filling... port velocity, ultimate static flow, and cylinder filling are interdependent, but static flow is not necessarily the best cylinder filling...

Thats correct rob, the gen 2 doesnt have squirters but does have the machined face there ready to be drilled and tapped for them.
Pugho, thanks for your reply, much appreciated. Did you guys retune the ecu or did it still retain the standard n/a ecu??
Thanks

That's weird.. The gen2 3SGE's sold over here have the oil squirters in them.
(We are all talking about the MAP-based ACIS engine that came in the '90-'93 celica, right? Not the old TVIS AFM one..)
It also has knock detection. This is probably why a gen1 engine would not have lived thru it.
As our turbo installation was just a low budget one just to show that it can be done, we used the stock ECU with a valve connected to the MAP sensor to let the excess pressure out. Before we put in the valve, the ECU responded to the unexpected pressure by simply cutting the fuel as the boost reached something like 4-5psi. Don't remember exactly how much..

Pugho,
Mine is a jap import gen2 and has no oil squirters just the machined face for them. Any idea what your comp ratio was??? Also what Ron is your fuel??
I wonder if infact you guys got a non turboed 3SGTE engine?? just a thought!
Also anyone ever checked the comp ratio of a gen2 3SGE N/A engine. If so what did you get?

Not too sure about the comp ratio other than that it is more than 10:1.
The fuel is RON 98. We also have an ethanol based fuel that is 85% ethanol an 15% gasoline. It's RON rating is also 98 and we discovered that the engine was a bit stronger on this fuel.
The engine is not a non turboed 3SGTE.. The 2 gen GTE still had AFM and TVIS, this doesn't. We didn't have to import our engine. The 2gen 3SGE is widely available in sweden as it was the only engine sold in the celica gti for several years. We never got the 4AFE or 5SFE.
I'm talking about one of these:

What about rebuilding the NA with forged pistons, then you get the strong fresh bottom end with the correct compression ratio. Also will the NA manual gearbox cope?

Pugho,
yep thats the same as mine, interesting that you guys have oil squirters and mine doesnt, perhaps diffirent specs for diffirent countrys??
RA45,
thankyou, i think i may have meet you from central vic auto parts?? Is that you Glenn Booth?
Geordie, its a rwd setup and ill be doing a g/box conversion to something stronger at the same time.

Hmmmm, why not just go with the 3sgte then? If your going to start "improving" on the 3sge, I am pretty sure it would work out cheaper to just drop the other engine in.

Im doing a high comp, low boost setup
