l24 vs l28 wiring harness

[Limitless]

I've been searching for whether or not the l28 wiring harness is identical to that of the l24. Does anyone know? I was unable to obtain this information on any of the z forums, but I apologize in advanced if this question has been addressed already.

I am going to be replacing most of the electrical wiring once I finish working on the mechanical aspects of my 71 240z(numbers matching block). In the future I may wish to drop an l28/l28et in my zed, and that is why I ask whether or not I would need to redo all of the electrical from my existing l24 engine to do such a swap. I would like to prepare my self for the future by saving costs.

I am also still puzzled why the potential of the l24 engine is so much less than the l28. Is this due to the lack of parts or the fact that no one has put in the time researching how to build an l24? I understand displacement is a big issue, but are there any other big reasons for why I see l28's reaching up to 600 hp but no l24's in that range?

If anyone knows if the l28 swap is literally a drop in swap, no modifications necessary, please let me know. I would be really satisfied if I am able to achieve around 300hp with my l24 block without a legendary OS Giken head.

There are L24's out there that will wipe the street with an L28. Look into Robello Motors in Cali. They build L series motors to woop arse.

The 240Z and 280Z harness's are completely different animals. If you drop an L28 into your 240Z, just use the existing wiring. Unless you're gonna do the Fuel injection L28, then you'll need the ECU and the associated harness that goes with it.

The 600HP L28 is no longer an L28. It's likely been stroked, bored, crank swapped, Turbo's or is using an N.O.S. system. Displacement is key when building the L28's and the Turbo L28 from a 280ZX is a better designed and built block. Bigger casting and such.

I'm sure there are a few members who will add to this or correct me if I'm wrong but you get the Just of it.

Welcome by the way. Ever head North to Marysville, Let me know if you stop by and BS for a bit.

Thank you for your input Dave. I will be sure to contact you the next time I head to Marysville. Hopefully there will be some local z/Datsun meets once I finish making my Z a reliable daily driver(Might take a while).

I would be privileged to discuss about cars/life with you as I am sure you have a great wealth of knowledge in z cars. This is my first car project.
