Identify engine revision Options

[ksporry]

Guys,
two questions really.
As said in a previous post I was thinking about installing a turbo on my celica. I have a 3S-GE engine, and others here stated that should be possible if it is a healthy engine. However, I understood that there are different types of 3S-GE engines around, so I was wondering how can I find out what mine is without disassembling half the engine and comparing ports etc.? Will the version be printed/stamped somewhere, and if so, where would I find that?

Also, I was wondering if I could use a CT26 turbo. I spotted one on ebay, new, and for a decent price (currently halfway through bidding though). are there any other turbo types I could use?

cool, that's a relief!
Have to say, not sure how you identified the oil cooler (I thought it was the smaller radiator in front of the main radiator; by the way, what's that second radiator for? For airco? I only saw one entry point, no exit point, and smaller piping than the main radiator). The filter is on the bottom of the sump.

By the way, I'm sure it snot as easy as 123 if I were to install a new manifold, with turbo and then into the intake.
I'm totally unfamiliar with tuning, so the less i need to do for that the better.
Wouldn't the ECU and fuel management computer manage all this based on the additional air going through the intake? If I were to do it this way, would it be an idea to install some sort of blow off valve (forgot the name of the type, but it woks on the vacuum from the head) between the turbo and intake to dump[ any air? I am aware that such a valve on its own wont be enough and I need to use the waste gate of the turbo as well to prevent compressor surge.

Anyway, tips are always welcome!
