Cam swap

Hey wats up group how hard it is to remove cam?? And is it convenient I out klze cams on a klde engine?? Any advice is appreciated

You have to take the intake off, which isn't that bad but if you've never done it it can be a pain. You also have to take the timing belt off, which is always a pain. I'd say depending on mechanical ability, familiarity, it could take anywhere from 1 hour to 6 hours.

Hard part is also the cam gears that are attached to it and thus will effect your timing.

Experienced KL worker can do in a hour I think, inexperienced 2-3. If all is stuck more

It is a time consuming affair to remove all four. All belts,valve covers, intake manifold, air cleaner, distributor & plug wires must be removed. The little aluminum camshaft hold-down caps MUST be installed exactly the way they were removed. NEVER get cam journal caps mixed up!

You will not get enough power gain to justify swapping just a kl31 cam set in. Its not worth the time unless you have the intake manifold, ecu re-map, and port-match at least. Still better to have the whole kl31 engine.

Ok so is not with swapping the cams than?? Cus I have 2 probes as of now one of em has the klze and it broke down on me im not sure what happened I just got tired of putting money into it cus I had some bills to pay have another probe I was thinking of building with the parts of the klze I've done plenty of work on my car but I hear cams are difficult to remove or install sonic wanted an opinion
but if fits not worth it o well
Reason why I wanted to do this is because the other probe I have is not running right now but was told by the the previous owner that the engine had been rebuild with aftermarket pistons so I thought adding klze cams would be a good gain???

(This was done w/ an AO6 ecu per interpret, not sure what that is but imagine it allowed them to control fuel curve at least)

Which KLZE do you have in the other car? You might find that it's just the distributor that's screwing you up in the other car.

If you have a curve neck ZE, then the cams in it are the same as the ones in the KLDE engine. Only the straight neck ZE has the KL31 cams.

If the ZE engine is actually toast...then swapping over the cams and intake manifold will make more power throughout the rev range, even without having port matching nor proper VRIS RPM opening times.

I got the straight neck ze and nah I don't think it was distribuitor, so what do u guys think, should I swap em?? And I'd
