I'm getting ready to perform a head swap on my 98 200SX-SER, which by the way runs good. I am having machine work done on a 97 head (also from a 200SX-SER) and noticed different stampings between the 2 heads.

Below the distributor, the 98 head has 94Y 1R and on the 97 head in the same location it has 94Y 1L. These were not covered in the listing at the beginning.... anyone know what the difference might be??

I just purchased a 53J 8L, was told it is a 10:1 compression motor. It is a High-Port, and it is EGR-less......black channel on the VC

Hi all

My LHD Bluebird SSS-G was originally equipped with a 53J block, and a 53J 2R head

After that one died, was swapped with a JDM 53J block, 53J 2L head

Can't find any of those codes on the list nor the descriptions posted here

The brochure that came with the car when purchased new indicates 145 hp, 132lb-ft tq. Have to go back and check the CR

Any idea of the codes???

53J 2R, normal pistons, highport, egrless and gold/black Valve cover

Here is an interesting one....

This was a BlueBird motor, although now we are beginning to wonder exactly what the hell it is.

I don't know anything about the turbo.

The head has 53J 2L stamped on it. Its a highport with no EGR. Has sodium filled valves, purple injectors.

Here is the weird part...motor came with a burgundy valve cover with a black channel. It wasn't supposed to, at least going by the codes that I have found. It should have a silver or a red cover.

The only thing that I can think is that maybe the valve cover was swapped at some point??

Yes. It won't be for a while though.....the valve cover is in my friends car, and it will be in the shop for a while for the megasquirt install.

Its a darker red than I have before seen.
