Exhaust manifold compatability?

Hey guys,
I have an 89 4wd with 22RE EFI. I have a cracked manifold and need to replace it. The question is. What is the difference in the manifold for an EFI or carb'd engine? Are they interchangeable?
Thanks

I guess the real down and dirty question is...
Is there any reason this will not go on my truck?

should fit. I'm pretty sure the difference is in the intake side, not the exhaust.

welcome to yotatech ...84 and older uses round exhaust ports and 85-95 uses pear shape ports and the 22r and 22re are pretty much them same

depends on where the O2 sensor is. You could use one that has a hole if you plug it, but if you need the hole and it doesn't have it, you will have to find a manifold that has the o2 hole.

Normally yes, but oddly enough the 22RTE turbo manifold uses round ports, while the head still has the pear shape. little bit of UFI

22r and 22re use same exhaust manifold.

you can get the gaskets at Napa. The manifold gasket is around $30 and the head pipe (2 on the manifold, 1 @ the cat) for a few bucks each.
