810 gas to diesel conversion (same engine as Z, so i figure it belongs here)

[Vodkaboy]

First question: are there any parts on the 810's L24E engine that i might want to put on my '77 Z's L28 with bad EFI and a ticking lifter (like EFI parts, better manafolds, better sensors, computer, head, fuel pump, etc)... otherwise, how much could i sell this engine for intact, considering it has less than 6000 miles on it since it got rebuilt (new cam, head redone, new injectors, new bearings, oil pump, rods, rings, checked the crank to be within spec, new alternator, etc)

second set of questions:

what am i going to need to convert this to diesel... im assuming the diesel fuel pump (the in tank one), the starter, im going to need to swap flywheels (unless one is severly incompatable with the other) as the current diesel has a flexplate, and the maxima has a 4 speed. other than that, just filters, and the such, then its ready to get converted to grease/bio diesel... anything im missing?

info:

my Z (for thinking about engine bits to swap): '77 280Z with a bad EFI system, and i think some quirks in the ignition as well. ticking lifter, and whatever stock head it came with.

810: 1979 datsun 810 with the L24E, tons of new stuff all over the engine, body is painted olive drab with a brush and it shows, came with an extra fuel pump, EGR system, wiper motor (what can i sell these for?), but is an otherwise straight car (transmission and rear end are in good shape, so i will be keeping them in it).

engine: LD28 from a 1982 Nissan Maxima (same car as 810, basically), currently has a flexplate, not a flywheel. to be converted to grease in the near future...

With the exception lf the Air Flow Meter, the ECU, and the relays, the 79 L24E and the 77 L28E have basically the same fuel injection. Is your 810 a 2dr? If so, there are not many of them left. Why would you want to convert it to diesel? Anyway, I believe they both have N47 heads. I have a 78 280Z and a 79 810 2dr. To convert to diesel, you would need all of the fuel system components, including the tank, the diesel ecu, and relays, wiring harness, etc. I have never done or contemplated such a swap but I have seen enough 910 (Maxima) diesels in the junkyard to know that much of the componentry is different. Looks like a lot of work but anything is possible.

the 810 is a 5 door waggon, in fairly shitty shape (the SOB painted it olive drab with house paint and a brush). i want to convert it to diesel so i can run grease on it, partially for my senior project, and partially for free gas (the Z has bad EFI, and is geting 8 mpg, and puffing out black clouds of unburnt fuel at stops, i cant afford megasquirt if all my money goes into gas which just drips out the tailpipe)... I have already checked the Diesel ECU, and all it does is cycle the glowplugs, and even with my limited electronics knowledge, that isnt too hard to just make a switch for

also, would it be advisable to swap the injectors, ecu, AFM, and whatever other sensors (thermotime, etc) out of the maxima, into the Z, just because i know that they all work (the guy replaced them all about 6000 miles ago, and has recipts)... i know i could use the fuel reg and injectors, because my fuel pressure reg leaks every once in a while (right on top of my exhaust manafold no less), and i have no doubt that some of my injectors are hashed

i remember looking at a comparison between maxima N47, and ZX N47 heads before, and they looked staggeringly different (i think i saw it on hybridZ, two heads side by side), and have also heard that the maxima/810 heads will give a slight compression boost on a Z... are the cam profiles similer? if they are, ill probably swap straight accross for the lower mileage, recently reworked head/cam...

The N47 heads on my cars look similar. Maybe because I am comparing a 78 Z to a 79 810. The 810 AFM mounts horizontally and doesn't work when you stand it up vertically like the one ine a Z. There is also a warning on the 79 and up ECUs that states "This ECU should, under no circumstances, be installed on 1978 or earlier year models. Otherwise damage to the ECU might result." All the other stuff, Thermotime, Cold Start Valve, Temperature Sensor, Air Regulator, Fuel Pressure Regulator, are the same. I've never compared the injectors because I've yet to have any problems with them on either car. I haven't located any specs on the cam profile of the 810.
