The engine bays are similar I'm led to believe, jsut different engine mounts and stuff. If you look in a gemini the gearstick is quite far foward and in a Chevette they are in the normal place. I'm not sure if the trans tunnels are the same or not tho. They also might run different X-Members.
I rekcon you could pick one for for about $30 on TradeMe.
DVLRCR: If its gonna be supercharged or turbo and it's already EFI, I wouldn't go trying to change it to carby. That's just silly.
Lowlancer vs Defcon vs Someone with a 2door Mk2 with a Pinto, oh yeah.
Meremere track day, oh baby!
Anyway, on topic. I know you are on HotGemini, and I gather you missed this thread:

Apparantly 65kw, but they are good engines. I've heard of 12 second 1/4s NA.
2.3 4ZD1 = 81kw
2.6 4ZE1 - 88kw but EFI so much more potential, a good few hundy HPs is not to shabby from one.
No, I said you could build the motor for $10 grand, but if he only has $10gs to spend on the entire car, then it's not gonna happen.
Saying that, they are very good engines, I have heard of at least 3 pushing around 600hp with no hassles.
the 4ZE1 would be my pick. 2.6 lt 4 cyc EFI. You can either use the gem or a rodeo gearbox and they prety much drop onto the standard mounts.
For 10 grand I rekcon you could turbo that, but only if the $10gs were for the engine alone. And this is not talking things like forged pistons (although you can buy them off the shelf in Aussie )
I rekcon just work the 2.6 NA it'd go like a dream.
Repco can get you ACL pistons. They are stock hypatec (or how ever you spell it) replacements, 30% stronger. They also come with ring.
Also, some cars offer a few types, high comp, etc.
Get an uno turbo engine and strap that puppy in there. My mate has one, they go unbelievably hard for what they are. Especially when you're hitting 20psi
