Help me Identify this 3S-GTE?

[Saavedro88]

A local-to-me JDM importer has an engine that he states [list=]came from an ST205 (unknown what year, exactly), however when I went to look at it, it had an Air to Air intercooler, and writing on the ECU t[/list]hat says "92 Celica." On the other hand, it had the larger, 4 runner intake manifold, which was his argument for saying it "definitely came from an ST205."

Can anyone help me figure this out for sure? Is there a number on the block that I could reference? Thanks in advance!

Looks like a gen3 with a st185 intercooler

Any particular reason that swap would be done?

[Tecker185]

Wouldn’t make sense to do that to a st205 because it does not have the scoop to allow air to go threw. Possible it was swapped into the 92 celica like the writing states.

Here are some more photos they posted today.

Hmm. That's an interesting suggestion.

The two plugs by the ecu make me belive the motor came out of an st185. So its a gen3 that came out of a st185 is my guess.

[Saavedro88]

So it has a 185 Harness?

[Tecker185]

Its got a modified st185 harness to run the gen3.

Man. Doesn't sound like anything I want to mess with... Thanks!

As others have said, looks to be a 205 engine made to work in a 185. It definitely has a 185 trans attached to it which supports this.

What's the tell for that?
And what's the benefit of having either the 205 or 185 transmission versus the other? (Which one is better?)

There is a selector on the transfer-case on the st185 and not on the st205. The st205 trans is better.

I remember when I went to check out this motor. Had me pretty confused when I first looked at it because of the way the labeled it. It's definently a 3rd gen motor with a 185 transmission.
