how would one know this by looking at a motor.
is there a difference in serial numbers or any thing that can be picked up on easy?

How can you tell if a motor is a 7m-ge/t

For one thing if there's a turbo on it, than it's a GTE... 
lol
Is it just the engine out of the car? I'd look at the valve covers... I believe only the GTE only theres a part on the valve cover towards the front that sinks down for where the coil pack sits...
Check to see if there's 2 knock sensors, I think only the GTE's have 2 of them..
As far as serial numbers or anything like that... I don't know someone else I'm sure will chime in...

7mge has a distributor
7mge has a different intake manfiold than gte
7mge has no turbo(unless converted over to na-t
heres a link to a picture of a 7mge(with no turbo)

there are quiet a few different things from ge to gte

heres a 7mgte(jdm but pretty much the same as usdm besides jdm has no egr system)

Easiest way to tell when the engine is out... look for the oil drain port for the turbo. If it's not there, it's a non turbo block at least.
Drain port can be drilled. It's more trouble than it's generally worth, but it can be. If it's not there, it's definitely a GE block.
GTE uses 2 knock sensors, front and rear. The GE has one knock sensor in the middle. Even if someone went to the trouble to tap out the other 2 bosses, the center one would be tapped for a GE block. (There are 3 bosses on the block casting.)
The intake cam IS different, but you won't be able to tell that visually, and some people have put NA intake cams into their GTE engines, so it's not conclusive.
[opinion]The only really important difference is that the GE has 9.2:1 compression, and the GTE has 8.4:1 compression stock. The GTE has oil squirters inside as well, but thay's a less important distinction.[/opinion] This can be checked by pulling the #1 spark plug at #1 TDC and inspecting the piston top. If the piston is dished, they're GTE pistons. If it's flat/slightly domed then it's a GE piston. You can see the difference through the spark plug hole if you're paranoid enough.
The block and head castings are the same, the cranks are the same, (for the same years) just a few things drilled and tapped differently for the different electronics and sth.
I actually kind of figured that a low boost build below stock FCO) with the GE pistons would be a fun build. Lots more bottom end from the compression.
