engine id numbers

[sweatybetty]

is there any way to determine if the engine is correct for the car by the engine id number if the tag is missing. i guess what i mean is, for example, would car #'s hls3025000 through hls3026000 have engine # xxxxx through xxxxx?

im trying to be fairly certain that my car has the original engine, but there is no tag. did nissan use these engines in other cars or just the Z's?

 

thanks all    sb

About the only way you can check your engine # is to locate a couple of VIN's that closely bracket your VIN, then check their engine #'s if original.  If your engine # is bracketed by those others, it is likely the original engine.  Mind you - I said likely but not guaranteed.

At one time there was an online spreadsheet that folks could enter their details.  Unfortunately, that site is now gone.  Perhaps someone on this forum made a copy for reference.  Post your VIN to this thread and see if anything pops up.

Carl has about the best reference. www.zhome.com   Engines were not installed in sequential order, though.  Don't make that mistake.  They were installed in the other S30 models as well.

thanks for the link. it appears that i have a late 1970 L24. the # is 15770, which falls into that time frame.

Its always interesting hearing about what has happened to our cars over their long history.  Does your 1970 engine still have an E31 head like it originally would have come with?

Here is an interesting thread on the subject of early engine numbers:
