ca18de into a 1990 nissan urvan, possible??

[nissan urvan e24]

hey guys just wondering my vans got a z20s engine in it which is s***house, I want a bit more torque whilst going up hills or cruising for that matter, the z20s just doesn't cut the cake. my q is will a ca18de fit onto the vans bellhousing, keeping in mind these vans came out with the ltd vg30 engines, so the box will be able to handle a na engine, and secondly will i need to modify the engine mounts, or would a s13 cross member fit?? I hear all that is needed it a bigger bearing in the gearbox??

Ive looked at a ka24de, z22e and z24e, z18et, ca20e and theyre all very limited to purchase in new zealand where the ca18de is common.

the vg30's are really hard to find and expensive!! not willing to cop out too much money for this project.

Why not turbo the Z20S? You could probably run less than 7psi and not have to change anything else.

hey man thanks for your reply but the motor is a piece of s**t and wouldnt suit a turbo due to its bad porting and porting it would cost to much for what its worth, plus its carburated so ide need a kit of of an old z18et i assume which again i cant find. just after something that will do well in the van not too much power but not too little and the ca18de has what im looking for and is available. anyone out there that knows if this can be done?? cheers i appreciate any response.

We don't have that van, or that motor for that matter, here in the US, so most of us won't have any experience with it. There are some ppl from New Zealand on here though, so maybe they can chime in.

Also, the CA18DE doesn't really have a whole lot of low end power. Below 3K, this motor is pretty worthless. I'm not saying it won't work, you just need to be aware that you're gonna have to keep it wrapped up all the time to keep it making power.

What about a KA24DE? Do they have that motor there? It's got a lot more torque and I would think that it would move that van around a lot better than a CA18DE would.

Regardless, anything can be done w/enough money. If I had to guess, you'd have to build custom motor mounts, custom transmission adapter, completely redo the fuel system as yours is probably a return-less system, and the fuel pump and lines are probably all way too small. The wiring will have to be figured out from scratch since none of them are going to plug into anything on your chassis. The FSM (Factory Service Manual) is available for download in the stickies. Either that or you'd have to buy a standalone. IDK what clearance is like, but you'll probably have to fabricate a custom intake, and exhaust as well. Another thing to consider is the oil pan. I don't know anything about that chassis, but it's possible you'll have to modify the oil pan so that it will clear the sub-frame.

You can turbocharge any internal combustion engine. Even if the porting is bad. You'd only be running 5-7psi. That would yield you an easy 30-60whp, which should easily meet your goals. I'd be willing to bet money that it'd be way less work to build a custom turbo setup than it would be to get a CA18DE into that chassis.
