In Australia you get a 2ltr v6 in some 323's (Astana /Potashes) I believe it to be a KFZE or similar, it has a very different intake to the ZE and the O3 and the K8.
Ok now to the question.. Dose any one know much about this motor.. <p> <p>I put a KLZE into my MX6, and now im fitting the O3 into the 323.
What im wondering is if any one knows things like are the fuel pumps up to supplying the 2.5 ?
Should I swap over the manifold from the KFZE (2ltr) to the KLO3 (2.5)? The internal diameter appears to be the same but the make up is quite different, like the VIRS chambers and over all shape/design..
I could ramble on and on, but dose any one have any experience with this motor swap?.
Thanks..

I just had a closer look @ the Astana..
I found the ecu sockets to be the same but different to the mx6 one.. <p>323 ecu
<p>mx6 ecu
<p>There was an extra unused socket on the kf ecu , but the remaining 3 went in perfectly to the o3s ecu, (I hope the pins are the same..)<p>The problem I think is going to be the VAF/MAF.. Who knows any thing about this?
You see the maf on the 323 has 4 wires just like the VAf setup on the mx6, but they are different colors and have a different plug on the end.. does any one know if all I have to do is splice the o3 s plug onto the other (I have a spare) and if so what is the color code/mach up? <p> <p>Or do you think im going to have to get a MX6 loom and swap it all over; including the dizzy (the dizzy is different as well) <p>and yea, it was night time so gi-me a break on the pics..

i am to putting a kf-ze into my 91 protege, and the fuel pumps yes they will hold but i would still change them to something better like i know a guy who did the same swap in a 91 protege and he's running the supra tt fuel pump, besides that everything else is fine and will hold up

Why would you swap a 170hp KFZE for a 170hp KL03?

2.5l has more torque, and moer horse power in the lower RPMs, the 2.0 has less torque and not much H.P. in the lower RPMs.

because at the time of purchasing the engine i only paid 400 for the kf-ze and the kl-03 was going for 900 so hey i went with what i could afford
