Can you please help me identify my SR?

Can somebody please help my identify this SR?

 

[thisismatt]

93-99 blacktop I would assume, because of the fins on the front of the head

Definitely an S13 180SX Blacktop, but 94-98. Ive got the same engine in my 510.

Sweeeeet!!! Thank you! Now, here comes the really DUMB question? Is there a way to tell from "markings" or a stamp?

And maybe the dumbest question..... Is it a SR20DET? 🤦‍♂️

[paradime]

No shame in asking. There is a casting number on the exhaust side all the way to the back near the bell housing. It shows SR20 6 numbers with a W at the end. The numbers correspond with the car's VIN. The serial number on the block gives no indication whether it's a DE or DET though. With a turbo haring off the side it's pretty clear it's a DET.

Exhaust manifold looks after market. Maybe someone put it on with a turbo?

[thisismatt]

I imagine that's what he's asking. Could be an aftermarket turbo'd SR20DE. I don't know if any way to tell without opening it up

[paradime]

Yeah, it looks a bit Macgyver, definitely not stock. The DE has 10:1 compression though, so hopefully it's not a DE+T

 

No need to split it open though.

The turbo coolant lines on a DET comes off the steel coolant passage behind the thermostat, and returns at the front of the block. If it's a de+t, the coolant line would likely be tapped into the heater hoses or the throttle body coolant lines. 

The turbo oil feed on a DET comes off the side of the block under the exhaust manifold and returns towards the front of the block. A de+t would probably have an oil line running from the oil pressure sending unit around the back of the block.

Yeah the DE doesn't have any of the ports capped like the RB's.  So the water and oil wouldn't be coming out of the block.  Sam drilled the oil feed in his block so he wouldn't have to run a long oil line and could run a DET stainless line kit.  He said it was the worst job even and his block was disassembled on the work bench.  He had to get a super long drill but from work to make it all the way through.

Here are some better shots of the rear.

Do any of these other images "help" with identifying with WHAT I have?
