yes. change out the engine, engine wiring harness, computer. the mounts between the 3 and 4 cylinder are 1.5" difference on the drivers side tranny mount. but the mounts are also different between auto and manual. you may need to make a spacer. remove flywheel, install spacer and torque converter

'95 is not an OBDII car. 98 is. That is a major difference!! Yes, parts will physically fit, but that's not where your challenges lie.

This swap is going to be more trouble than it is worth. Just find the right motor instead of trying to make this swap work.

Unless you really want the better power from the 16 valve engine compared to the 8 valve :deal

True. But as far as Metro work goes, this is "graduate level" stuff. Plus, he is talking about taking the 4/A out of a '95 and putting in a 3/5 from a '98...not an 8V-to-16V deal.

It would be easier to just find a 3/5 in the first place if for no other reason than the mentioned OBDII issue. Unless the car taking the 3/5 is a sedan?

Were it me doing the swap, I'd try to find a '95-ish powertrain to swap in. I think it would be a lot easier?

" 98 metro 3 cylinder stick if I take that engine out will it go into my 95 metro that has a 4 cylinder automatic"

complete engine wiring harness and computer from the 98 3. install in the 95.
keep the upsteam 02 sensor for the 98, down stream sensor just secure to the firewall so it just reads "clean air" computer will be happy

FTFY JM :thumb
granted i think the 3 cylinder has more low end torque than the 4 cylinder does

he never mentioned swapping the tranny's, just the engines.

Soooo...a '95 3-cylinder automatic? Wow. I couldn't imagine anything more gutless, and I drive a Metro!

Yeah, that would be miserable. That's why they never built them that way. And 35 mpg would be the most you'd ever see, long highway trip at 50 mph.

If roughly 30% (or more) less is more, then it does. :hmm

you misunderstand.

the cylinders have more low end torque at low rpms than the 4 cylinders....once the 4 cylinders get a few rpm they quickly produce more torque.
the 3 cylinders feel like a tractor starting out, 4 cylinders feel more like a regular car....no low end punch, but lots of higher rpm punch

I understood perfectly that you believe it has more low end torque. What I am skeptical about is whether or not this is actually true.

Maybe the heavier weight, not comparing equal final drive/tire combinations or engines with equal compression/performance etc. can make it seem that way, but I would love to see a torque curve that shows the 1.3L torque curve having less torque on the bottom end.

It's pretty much the same engine but with an extra cylinder to produce torque and hp with for a very small weight increase. It has 33% more cylinders, produces just under 30% more max torque - so what would explain it having less torque on the bottom end? Are the cams a drastically different profile or the ECMs that different in their fuel mapping to limit the torque it produces at low rpm?

While I realize it's not impossible, I'm just interested in actual data and/or facts to support your assertion.
