  1. Actually, the Z24 pickup bolts right up to the KA24DE bottom end and everything fits properly! It's pretty amazing how similar these motors are in the bottom end; honestly I think that's the saving grace of even attempting a swap like this. Wife is credited for all the work though, I've never lifted a welding tool before. She's the one that did all that. (=
  2. Steer box swap was a bust -- the power steering had an entirely different set of links. So that sucks. But found a friend rebuilding a manual steering 720 so gave the box to him; not a total loss. On the other hand, the oil pan was a great success. It seals and it's beautiful after powder coating in a metallic version of Nissan Blue.
  3. Alright, slow updates but we're still working on it. As far as I can tell this may be the only KA into a 4WD 720 that's been done. The wife is going to have to kitbash the timing section of the KA oil pan to the rest of the Z24 pan. Thankfully the Z24 sump bolts perfectly to the truck KA and the Z24 pan bolts right on except for the timing area. So then we're going to cut each and weld them together to get one oil pan that will fit around the front diff and bolt to the KA. Pictures and walkthrough will come once we work through it. Other thing we're working on is swapping the lower section of the steering column and the steer box for a manual one -- keeping the top part to keep tilt steering. Using it as an opportunity to replace that old u joint while we're at it. Wouldn't bother otherwise but this simplifies the swap.
  4. We just pulled the z24 out of a 720, might have one for you. Not sure if it works, though: it wasn't connected when we got the truck.
  5. The KA has landed! Fresh off the slow boat from Jersey comes a 140k mile specimen...which doesn't look too horrible all in all. Mechanically it looks pretty complete. All the brackets are there, although the power steering pump's pulley is fragged, but we're not keeping that system either so that really doesn't matter. The a/c ompressor bracket is bent so we'll just have to use the Z24 bracket. No exhaust bits came with it, and the EGR pipe was chopped so we're kinda forced into getting the blockoff plates for it regardless. This also means having to find a header that will fit in the 720 without fouling against anything. Obligatory head casting and block serial number shots, because why not document Everything™ while we're here? The oil pan is definitely from a 2WD Frontier, so kitbashing a pan between the Z24 sump and the KA24DE mount has to happen. Unless by some miracle the 4WD KA24DE oil pan can fit around the 720's front diff, but just from looking at pics I doubt it can. Images can be found at https://imgur.com/a/QpuHdpa So, open questions raised by this: • What exhaust header can we use that will fit around the differential, steering shaft, etc? • That 'little' problem of the oil pan, so far I don't see any other 4WD D720 KA24DE swaps so I'm hoping I've just missed a thread and someone has done this
  6. Huh! Haven't and just ordered the unpowered steering kit. If it ends up being too stiff for the owner we may look into that, thank you for the pointer!
  7. Another decision made: Getting the manual steering rack and intermediate shaft so that we can avoid having to plumb power steering with the swap. Working on that today. Plus the motor will be here on Monday 7 December! Progress is being made. If anyone needs Z24 partout parts please contact me! We've got a whole Z24 we need to make go away and would rather not ditch it for scrap.
  8. So let me preface with: This is my partner's build, but he doesn't really do forums so I'll attempt to document it here. Vehicle: 1985 Datsun 720 King Cab 4WD Motor: 2002 Frontier KA24DE Wiring Harness/ECU: 2000 Frontier KA24DE We scored an entire Frontier wiring harness w/ manual ECU out of a 2000, everything forward of the taillight harness so we're sitting pretty there. So this all started with a desire to do an L28ET swap, but, well, we're not quite up to extending the frame rails. Which led us to a KA24DE. Looks, from reading the forums, pretty straight forward on a 2WD. On the 4WD, the oil pan is going to be a pain that requires custom fabrication so far as we can tell. Where we are right now: BHG Z24 out and torn down for inspection/parting out, KA24DE ordered and awaiting arrival via freight. Pictures so far: https://imgur.com/a/SNwOnS5

    Hey crew! We have a Z24 out of a 1985 Datsun 720 that suffered a catastrophic head gasket failure. Now we could probably fix it up but instead we're doing a KA24DE swap. We'll be keeping some sensors and other oddments for keeping the factory dash, but otherwise, any part of the motor from carb to block is available, buyer pays shipping. We'll be keeping the oil pan as a reference to use in our swap. Notable items available: • Carb + feedback computer • Intake manifold • Exhaust manifold • Head • Camshaft • Block • Crankshaft Other parts are available, just ask. Make an offer on part prices, we're aiming to be very reasonable. EDIT: Verified this died to BHG, photos of rotating assembly and head included.

  10. Haven't cracked open the top loader plate yet. Can it be gotten to through that?
  11. Hello! So I'm the proud owner of a 1985 Nissan (ne Datsun) 720 Pickup Deluxe 4x4 King Cab. Beautiful, beautiful truck. One minorly annoying thing is the 1/2 return springs are conspicuously weak. 5/R return springs are as strong as any new car I've driven, but 1/2 is just lazy. While this doesn't impact functionality greatly, it does rather mess with the way I drive. To be truthful, I rely on the return springs to line me up on 3rd gear when shifting up from 2nd. With it as weak as it is, I often hit the finger in between the 1 and 3 gates instead of actually hitting 3rd. I'm not seeing any repair kits that include return springs, though being it is a top loader I'm wonderin' if anyone else has experienced this and found a way to fix it short of a full gearbox teardown and finding a part for the return spring. Thanks! -Atma
