UPSMT280Z Posted May 3, 2010 Share Posted May 3, 2010 I now know that the turbo motor in the 83 i just bought is not the orig motor at least i dont think it is. the vin is JN1HZ04S5DX562626 and the head is a N42 engine id on the pas side of the block is L28 104455. The h in the vin i think means non turo car where a c would mean turbo. Any help with finding out what motor i do have. Quote Link to comment Share on other sites More sharing options...
jcub280 Posted May 3, 2010 Share Posted May 3, 2010 The h in the vin i think means non turo car where a c would mean turbo. Any help with finding out what motor i do have. When I ID a motor/car I just look it up in one of my handy books or check out these site Black Dragon - Page 7-8 if it does not go directly and for the engine I just do a search at this site and zcar.com and this is what I find. zcar.com motor ID Your car sounds to me like a n/a because of the H and the engine from before 81 due to the n42. Someone might be able to ID it better by using the numbers you listed. Quote Link to comment Share on other sites More sharing options...

19762802+2 Posted May 4, 2010 Share Posted May 4, 2010 The N42 head didn't come on the 83 so that has been swapped and most likely someone swapped a turbo engine into your car. the stamping on the block to tell if it is a N42 or F54 is near the left engine mount. I'm also confused why your so interested if it has been swapped, is there some reason? Quote Link to comment Share on other sites More sharing options...

I am interested because i bout the car thinking it was a turbo car with the intentions of getting running first and then swapping it into my 78 2880Z. I expected to have to do some work just trying to figure out if its gonna be way more than i thought. Were the N42 blocks and heads that were built as a turbo motor? The ecu in it may not even be a turbo ecu if so maybey go strait to a MS system. Just lost of questions popping up. Quote Link to comment Share on other sites More sharing options...

Did you find out from the previous owner if the car was running before in its current state? That would have answered your computer issue and a lot of other questions. The reason they would swap different heads on could be for lots of reasons such as different CRs. I think you should do some searching about Turbo engines most of what you want to know has been covered. Quote Link to comment Share on other sites More sharing options...

Ill try asking the guy i bought it from, but the reason he had the car was because he owns a tow yard and was asked to tow the car from a shop because the previous owner had what looks like the motor rebuilt all gaskets etc look new like the engine has never been run or run very little. He was asked to tow it because the ownwer didnt have the money to pay for the work and jst abandoned it Quote Link to comment Share on other sites More sharing options...
ArchetypeDatsun Posted May 5, 2010 Share Posted May 5, 2010 Just google your ecu number and take your time to look and match it up with your car. Me on the other hand when I bought my 83 turbo donor car already had a different ecu off a Z31 how I found out was googleing it and match up the number to a Z31 turbo Quote Link to comment Share on other sites More sharing options...
