22r exaust manifold vs. 22re exaust manifold

darth brian · 02-06-2006, 11:46 PM

are the stock heads on the 22re bigger or wider than the stock exaust headers on the 22r? i could possible gram them from my brothers 4runner and put them on mine if its worth it

The only difference I know of is the shape of the exhaust ports, but I think I read that if you use the older style gasket everything will bolt up just fine... Since the parts are donors you should try it and let us know!!!

there are no differences between 22R and 22R-E ports as long as they're of the same generation(e.g., 81-84, or '85-95).

the manifolds may themselves be different, as most 22R-E engines had an O2 sensor on them.

im pretty sure 81-84 used round ports and the 85-95 used pear shaped ports

so i would be wasting my time putting an '87 manifold on my '85? got it

No, the 87 manifold should fit the 85.

The block/head change was 8/84. Late 84 and up are the same block and head, 22R or 2RE.

darth brian · 02-09-2006, 02:24 PM

yea im sure it will fit. the only thing is will it make a difference? different shape and/or wider pipes? thats a lot of work to just replace it with the exact same thing.

Elton · 02-09-2006, 05:20 PM

there all the same size

Did you ever change exhaust amnifolds?
I have a '94 "Truck" that seems to be getting noisier & noisier at manifold....thinking a header....I hear that exaust bolts are always coming loose. Would you agree about looseness?
Do you think the return pipe for EGR is also problematic as far as looseness?

kyle_22r · 02-18-2006, 10:20 AM

what return pipe? on a '94, the pipe on the manifold is the air injection system. the EGR is internal.

you've probably just got a plain old exhaust leak. yes, the studs often loosen up, break, or the nuts come off. personally, i like to use a remflex exhaust gasket, and ditch the factory nuts for a plate washer, lock washer, and a regular nut. i've never had problems with leaks or loosening up with this setup. the remflex gaskets are so thick that they can seal a warped/pitted flange in most cases. of course it comes at a price, about $25 for an '85-95 22R/22R-E, but i think the factory gasket actually might cost more.

So I just bought my donor truck...its has an 84 22r in it with an 87EFI conversion and exhaust, it all bolts right up so you should have no problems!!! hope that helps your decision!!

i think that on the late engines, the only real difference in exhaust manifolds was that some(mostly before the 90s) had the O2 sensor mounted on the manifold. my '91 just has an untapped boss, my O2 sensor is located down by the cat.
