Will a 1989 suzuki engine interchange with a 1995 tracker?

Answer 1

Yes it should, with a bit of work. But first, is the car registered or do you intend to register it? In CA anyway, it is illegal to put an older engine in a newer car, and if you do and get caught you will not be able to register the car. It IS legal to put a newer engine in an older car, but technically then it must pass the smog rules of the newer engine, which means it could be problematic. But if you're looking at a pure off-roader that's something else. The reason I say "it should" is that Geo Tracker 1600cc engines were commonly swapped into Suzuki Samurai's to give them more power. Generally you would put an 8 valve Geo engine into a Samurai...if you had a 16 valve Geo you had more stuff you needed to bring over with it. SO: If your Geo Tracker has an 8 valve engine: The samurai engine should be able to reuse the same intake and exhaust manifolds. The bell housing of the transmission will probably not have "ears" in the right places to bolt onto the samurai block, so it will need modification. And there may be challenges with the starter too. I never made a tracker engine -> samurai body swap but had read a lot about it. Some folks sold an engine/transmission adapter plate, others talked about just having someone who could weld aluminum weld on new ears on the bell housing. Since the Geo is fuel injected, it uses an electronic fuel pump at much higher pressure than the carburatored samurai used. The Samurai "head" will have an eccentric off the camshaft to drive a rod out the side of the rear of the passenger side of the head to drive the mechanical fuel pump. But since you will be reusing the Geo manifold, fuel injector, and fuel pump you do not need the mechanical fuel pump off the samurai engine. So you could just unbolt the samura fuel pump, pull out the little rod or shaft, and then make a small trapizoidal shaped plate to bolt on in place of the fuel pump so oil does not pour out the fuel pump hole. IF you have a 16-valve Geo I would not consider using a Samurai engine....you would have to swap in the Samurai intake manifold and carb, and keep the mechanical fuel pump and disable or eliminate the stock geo one, and on and on. It would be a lot of work to have a much weaker engine.
