84 B2000 Engine Swap Options
Hey wanted to ask since I'm buying a 84 Mazda b2000 and i wanted to swap it with something in the Mazda family, and was wondering if it would be a good idea to swap in the MZR 2.3 from the speed3, Or Should i look into other brands also like maybe a ford V8 if it deems not worth it

Go with a carbed 302.
If the parts are available for that engine, sure, you can turn that engine longitudinally and use it for rear wheel drive. That’s a big if, though. If it is a direct relative of the 2.3L that went in the 20001.5-2012 Rangers, then it could work.
Then, you have the engine controls. Your truck won’t have anywhere near the inputs required to run a newer engine properly. I mean, it can be done, but you will lots and lots of studying of wiring schematic and splicing to do.

How about something like the 2.6 Mazda engine from1986 or 1987 B Series. Oh wait, I see you are in the Republic of California and might have to research emission regulations for an engine swap.

yea im looking for options that pass CA ****ty smog checks but i have a few ideas on how to pass that since anycar before 90s and is obd1 has a lot more leeway but from what ive read so far a couple v8 options may be ok or maybe the 2.7 turbo that was mentioned earlier just would need alot of custom wiring which i think i can do luckily
