engine identification

[spyderdrifter]

So I just installed an engine wire harness from a '95 GSX into my '95 GS-T. Had no issues putting it in, but my car still won't start. I've been reading around and found forums which talk about swaps to the CAS if a 1G 6-bolt is put into a 2G and by the description of the sensor swap with it, I think that may have been done to mine before I bought it. How do I find out if mine is a 6-bolt without removing the transmission to look at the flywheel? Is there any identification codes stamped on the block that I can research? I know there's certain apperance differences between the 1G & 2G engines and mine looks like it should be the 2G 7-bolt but now I'm not too sure it actually is. Thanks in advance.

Take some pics of the oil pan/ oil pump housing/ CAS and post them.

That's some handy info to know, thanks. With this info, are the oil pans interchangable between 6/7 bolt engines or only one or the other will fit?

First sentence from that link:

Top is an early 6bolt oilpan, bottom is a late 7bolt oilpan. There are 2 key differences between them

They can't be interchanged.
