My Datsun 620 - 2024 UPDATE What's Next??? 

Sr20 will be awesome for more longer road trips an abit more power will be alot more fun 🤩

Beautiful 620! I have a 77 King Cab here in the US and I'm doing a ground up restoration and channels like your really help keep the motivation going! You can get 18mm tall poly bump stops from Energy Suspension which fit the same thread pitch for the stock location - that will cure some of what ails you, suspension wise

Hell yeah man clean truck

great looking truck first thing i would do is a compression test on the engine mate

Trucks awesome I really like it , can’t believe how cheap the floor pans are !, shame to scrape that engine but if it’s giving you gyp all the time it’s definitely time dude that new engine looked like a monster 😂 thing will be a beast . Nice one I’m jealous I wish it was mine lol safe trip 👍

I FINALLY FOUND A GEM OF A 620!!! It's a 74' short box. So excited im getting it tomorow!

Rebuild the engine! Here in thailand there are loads of part availeble. Just put a j16 cranck in my j15 engine, higher compression. Keep it original i think. Loads of Thai 620s already run with sr20s

That SR looks like it was some late FWD version maybe from a Bluebird or Pulsar , Nissan wiring is very simple and mostly all the same with not much change between engine year versions. I wouldn't bother with the a aftermarket ECU as you will surely be able to find all the ECU pin outs etc online . It seems that they had the engine running no problem , A/C will just need a signal from the compressor clutch or cabin switch and you might need a speed signal that depending on year might have come from the ABS or just a sensor on the gearbox . You can just use a aftermarket electric drive for the older speedo to be driven that can be adjusted . There shouldn't really be too much that is needed to be wired outside the engine harness and for the labour price there I think it would be far cheaper than a aftermarket ECU and have good old Nissan reliability . Or you could take the loom back home and strip it down , extend the wiring for what is going to need to be ran to the original truck wiring in your sweet time . I would be finding the original throttle body to AFM rubber as there always built with a flexible section and the AFM are always rubber vibration pad mounted to the vehicle with Nissan's or the AFM is bolted on the air filter box that is rubber mounted , it won't last long with the engine vibrations from that stiff silicone hose they prop'ed up to start the engine up . Gearbox I wonder what is commonly used in Thailand as original SR RWD boxes are all mostly gone from the planet , If you can find a RWD bell housing there might be more Navara truck gearboxes over there that would require you just swapping a SR RWD bell housing on to the gearbox . Maybe the gearing would be more suited for the truck as well . Another mostly unknown bell housing pattern that is close are F series Honda that from memory we only had one bolt location to drilled to convert one to fit a SR gearbox bell housing to a F20C . So maybe whatever they use for F of K series RWD conversion in Thailand might be another option.

I have the same problem with front brakes on my 620. I think the 720 conversion is not plug and play so please if you do it lets us know how it went and is needed to make it work. :) I was thinking on getting adaptors made like in the USA and use D21 calipers and Isuzu rotors...

When my 620 arrives, I'm going drop spindles. It's a 79 so already has disc brakes
