My KLZE Festiva Build Thread

hybrid axles would definately make the swap easier but it hasn't been that difficult so far

On a side note, where i got the probe tranny there is 2, KL-DE engines, so once i get the probe transmission ready to accept the 323 axles i'll be looking to bring one of the KL's home with me :evil4:

<--- I suscribe!!

When i do the swap I plan on using the k8 trans and making some hybrid axles.

I'm going to be bringing both the diffs into my work tomorrow to get the diff pins out and make the attempt to swap the spider gears, i messed with them just a little bit today, without pulling the diff pin i can pull two spider gears out (the ones the axles go into) and the teeth are even different between the 323 and probe gears, they just have a different slope to them

Another thing that looks like it will be different is the diff pin thickness, which i can see will be another road block to swapping the spider gears, since the thicker diff pin from the probe tranny probably won't fit in the 323 spider gears. If thats the way it ends up i'll just take the 323 gears and have them machined out to fit the probe diff pin

The one thing i'm really learning with this project is all the parts look identical until you try to mix-match them, then you see the differences

youll probly need to take it to a machine shop and have it drilled off

Thats what i'm thinking too, which is why its the last resort

Click for awesome.

So, am I right in guessing that the implications if this doesn't work are that one would have to adapt the Probe parts or get custom axles? If one can shorten axles, what is to stop one from making half and half axles? (Half Probe, half 323)

Well i hit a bit of a road block today, i was going to re-assemble the probe tranny with the 323 diff and when i set the diff in place and re-installed the gear shafts, i checked the play between the ring gear and the gear shaft and it feels like too much play, so next i will tear down the spider gears and see how well they interchange

As a last resort i'll probably just swap the ring gears, but that looks like it could be a challenge all in itself

iirc most of the difference is in the heads and intakes. You really don't have to worry about breaking axles. The transmissions are the real weak point. The 4wd g series go up around 250hp the 2wd aren't as bad but they don't like alot of torque. Theres alot of threads on clubprotege and fordlaser about strengthening them.

thanks for that tidbit, i'll be sure to check out clubprotege/fordlaser for that info

KL-D/ZE Different parts:

Intake
Heads
Camshafts
Domed Pistons (ZE) causing higher compression
JDM ZE has no EGR system
Non integrated coil on the distributor (ZE)
ZE is OBDI

I'm still looking for a specification sheet, but what I'm finding is that the best setup for a strong, reliable KL motor is to use:

DE Block and internals
ZE complete heads and intake
DE valve retainers as the ZE tends to drop valves... frequently

I'll pull some info from performanceprobe and post it up for both our benefits and anyone else who is reading this.

[Damkid]

They do use an entirely different transmission. I can't remember the code right now, but it's not anything that would mate. You would have to adapt the Contours hubs etc. I don't think it makes much more power than the KL-DE either.

I'm reading on performanceprobe right now (wading through it is more like it), but besides compression, what are the differences between the DE and ZE? Since I'm planning on running boost with it as well, I would be at an early advantage with the DE, would I not. Then I could just build a lower compression block when I'm ready to really put some PSI to it. I'm guessing the heads have different flow geometry too?

I'm not too sure on the internal differences between the DE and ZE except the HP numbers and i beleive the intakes are slightly different
