GEN ? 3S-GE

i have a newer 3sge in my st162 celica, which im pretty sure is off an mr2. i was wondering if i could tell exactly how old it is, and what sort of generation it is.
if im still running the same aus stock ecu would it still have the stock 103kW at the crank power?
it still has tvis on it as well if thats any help to my question.
what sorta power should i expect from it, and should i be running higher octane fuel?

If it has TVIS then it's likely a 1st Gen 3S-GE off of an ST162. The SW20's (MR2's with 3S-GEs) have 2nd or 3rd Gen 3S-GE depending on the model (I think the GT limited ones had the 3rd Gen).
As for your power output if you actually do have a 2nd gen head (which is hard to tell without removing it to check the port sizes etc) then it will likely be limited (to an extent) by the 1st gen running gear that is still on it, so expect anything between 75-80kW at the front wheels.

Hehe, I've got one of these transpalants sitting in a ST162 in the shed too. there's no easy way of determining engine age, though you could try running the engine number if you can find a dealer who'll give you the time of day!

Dude,
You can tell by the Cam covers, or so I'm told.
Gen 1 has 2 seperate cam covers.
Others have 1 cover for both Cams.
Or post a photo here !
Cheers

so what does that mean for hp? would i notice any diff if i had the gen 1 ecu?
how could i tell what ecu i had?

also does having tvis make it a disadvantage or advantage or no difference to performance?

Matt,
you have a Gen 2 motor fitted with Gen 1 manifolds and ECU.The power gains that yeilds are difficult to tell, Gen 2 motor produces 117kw (14kw hike). HOWEVER there are three main differences from gen 1-2. Ecu mapping, Compression ratio and Inlet manifold design. Not having the intake and ecu from a gen 2 will starve it of top end power, the gen 1 manifold is aimed at producing low end torque. But, you do have added compression on your side.
SO! The theory of it is that you'll have better low end torque than a gen 2. You'll have better midrange torque than a Gen 1 (thanks to compression) but the top end power difference would most likely be minimal.
Cheers
Steve

so if i get a new ecu or a programmable piggyback system. i should get close to 117kW at the crank?
would it be worth trying to find a new intake manifold?

I believe unichip make a piggyback that that gets a gen 1 close to 117kw, Programmable ecu is always going to be the best performance upgrade on anything, but then of course youd have to factor in tuning and what not.
The problem with putting on the newer intake manifold is youd need to run the gen 2 wiring & ecu as well. this then becomes a significantly greater task if you plan to do the work yourself.
I would suggest a decent CAI setup and a set of extractors would be your best bet, a programmable ecu only if you have bigger plans for the car.

anyone have a rough estimate on how much a programmable ecu costs? what sorta gains i would expect from one, and what exactly did you mean by bigger plans for the car?

well theres heaps you can do to an engine to extract performance, to get the most of any modification it should be tuned to suit with a programmable ecu. You have to decide what kinda power youre chasing. If you wanna build a monster engine then it goes without saying that you need aftermarket management, if you want a nicely powered reliable motor in a non-turbo motor i would stick with the basics and be satisfied with the small power hike.

4th gen 3S-GE BEAMS (AKA red top) also came in the ST202 Celica SS-II and SS-III
