L26 engine replacement

Needing help resolving a problem....I have just inherited a saw bench operated by a 6 cylinder L26 engine and gearbox, but the engine seems seized....I haven't looked into what's wrong yet as I have no knowledge of these engines or gearboxes, but I'd like to know what would take its place if it's a boat anchor...

Almost any engine will do, so long as it is about the same size/power/torque.  These days, the smart thing to do would probably be to find an old Holden/Ford engine, or maybe an old other Nissan/Toyota of the same sort of vintage.  The reason is that anything much newer will be fuel injected, and then you need high pressure fuel pumps, the ECU, sensors, etc etc all working. Old carby/distributor engines are much simpler for this application.

If it were me though, I'd get an engine from a ute.  2.5 or 3L 4cyl fuel injected.

But see if you can oil the bores and get the old clunker turning first.

I am certainly going to try to get the original engine going as it will be easier than having to source a new one not knowing what sort of Nissan this engine came out of....

Thanks for responding

What other engines will this gearbox fit if I can't get it going and can't get another L26 ???

It would have come out of a 260Z or a 260C sedan, seeing as that's about the only cars that had them here in Australia.

Could you elaborate a little bit more for me please as I'm not familiar with anything Nissan...

Thanks for the input so far....much appreciated...at least I have that engine number you supplied..

Cheers

He's having a joke, because the RB26 is the distant descendant of the L26, and is the motor from the R32-4 GTRs and is the answer to every question (other than those questions to which the answer is LS1 or 2JZ).

Any Nissan L series engine will fit the box.  That's all the 6s and the 4s.  The 4s are a likely to be a little weak for the task.  There were also some other Nissan 4s, with bigger sizes that I think share the same block/box mounting pattern.  I think the Z series are like that, but I'm not enough of an old Nissan tragic to know or care.

I think if you have to change the engine, you would consider changing the gearbox too, because an old manual box for an old Ford/Holden/Nissan/Toyota shitter engine won't break the bank and will vastly open up your options.  To be honest, when you said the engine was running a sawbench, I did not even picture it with a gearbox.  I figured some direct flywheel attachment was in order.

If you really want to power it up, get a 3.8L V6 from an old Commodore, along with the manual box and the necessary fuel injection gear and make it turn the bench upside down on throttle crack!

I pulled the plugs out &  found cylinders 2 & 4 full of water...after blowing out the water I put a cap full of oil in all the cylinders then put tension on the crankshaft and tail shaft/drive shaft with 3 foot stilson and a  fence strainer because I don't have a chain block.... I'll see if anything happens.....

You might have to pull it apart and give it a prostitute's rebuild.

That's why I wanted another engine....I really don't want to rebuild an old engine....

I'd really like to find an old car still running for the engine...

But I don't know what car to chase down...

My 2 cents is anything with a carbie, I've seen a ton of waterpumps running on old 202 motors, hell some old diesel 4 cylinder engine would probably be better torque wise.

You could most likely pick up a old banger for a couple of hundred and then sell the L26 and not lose a cent in the process.

      R34 Skyline climate control unit transistor

      By sinn3r · Posted

      perhaps i should have mentioned, I plugged the unit in before i handed over to the electronics repair shop to see what damaged had been caused and the unit worked (ac controls, rear demister etc) bar the lights behind the lcd. i would assume that the diode was only to control lighting and didnt harm anything else i got the unit back from the electronics repair shop and all is well (to a point). The lights are back on and ac controls are working. im still paranoid as i beleive the repairer just put in any zener diode he could find and admitted asking chatgpt if its compatible   i do however have another issue... sometimes when i turn the ignition on, the climate control unit now goes through a diagnostics procedure which normally occurs when you disconnect and reconnect but this may be due to the below   to top everything off, and feel free to shoot me as im just about to do it myself anyway, while i was checking the newly repaired board by plugging in the climate control unit bare without the housing, i believe i may have shorted it on the headunit surround. Climate control unit still works but now the keyless entry doesnt work along with the dome light not turning on when you open the door. to add to this tricky situation, when you start the car and remove the key ( i have a turbo timer so car remains on) the keyless entry works. the dome light also works when you switch to the on position. fuses were checked and all ok ive deduced that the short somehow has messed with the smart entry control module as that is what controls the keyless entry and dome light on door opening   you guys wouldnt happen to have any experience with that topic lmao... im only laughing as its all i can do right now my self diagnosed adhd always gets me in a situation as i have no patience and want to get everything done in shortest amount of time as possible often ignoring crucial steps such as disconnecting battery when stuffing around with electronics or even placing a simple rag over the metallic headunit surround when placing a live pcb board on top of it   FML

      Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

      Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.
