will my '90 engine work in a 92?

I have both but the 92 sidekick has bad compression and the 90 is too rusty but engine is good.

is it a 8valve engine, mixing 8v with 16v is very hard. radial diffs , and EFI.
the 90 is 8v. so if the 92 is 8v, swap long blocks.

Yes both are 8 valve

1.6L 90 in a 1992 car is great. (the engine number is on the lower left lower bell flange, G16Lxxxxx (L = the letter for year) G13 were used in 1989.....
USA, rules.....

just keep the old parts, intake manifold , and exh, man and all electronics the same. just replace , the long block, neat, (just block and head swapP
the 89 has unique parts,
throttle body, and injector and ISC, ECU.
and intake manifold and sensors.
