easyBob: Nice post man!


In regards to "RECOMMENDATIONS(as in "not required") BEFORE INSTALLATION: 10) Complete reseal



Now I understand the IM gaskets are going to be different, I'm just wondering if there are any other differences? POssibly a completely different gasket kit for the ZE? (Different O-rings, seals, gaskets etc...) And where is the best place to purchase?
Thanks

[easyBob]

Most of the stuff I used I got from Ford. The only things I didn't get where the IM gaskets. I bought some spacers and sealed them up.

Things like piston rings and more complex stuff I didn't touch. Basiclly just new head gaskets and bolts....

Someone on here got a shop to do the reseal for them, can't remember thier name though. As for kits, I think there is one for the 03, but not for the ZE that I know of.

Ok, I'm still a little confused about the VAF, Disty and PCM/ECU

First off are the PCM and ECU different things, if so, what is the difference?

Also, why use the MX-3 VAF? Isn't there a J-spec VAF that works with the J-Spec ECU? Or is the MX-3 basically the same thing?

Also, if I swapp over my distributer, will that cause problems since the J-spec uses something different?

The reason I ask all this is because I'm in the market for a ZE motor, and one place will sell me the motor with the J-Spec disty. Should I go for this over swapping mine? Mine is actually broken, so I would have to replace it anyway.

Ok thats all for now, sorry I sound like a newbie, but hey I gotta ask...

I'm not the electrical expert here, but I believe they are the same thing, just different names. The Haynes used the PCM (Powertrain Control Module I think), so that's what I use.

Also, why use the MX-3 VAF? Isn't there a J-spec VAF that works with the J-Spec ECU? Or is the MX-3 basically the same thing?

They send the same signal to the PCM, so yeah, they're the same.

Also, if I swapp over my distributer, will that cause problems since the J-spec uses something different?

That, I'm not sure about. I know that some people switch back over to the j-spec one when they get MSD stuff, but I haven't done any of that, so I'm not sure.

I thought I would add my experiences, because I am probably one of the few people running a j-spec ZE with it's original ECU, wiring loom, VAF, and probably lots of other little bits.

Here's my story, I bought a front cut from Japan. From what I can figure it is an approximately 1993 MX6. Could have been a 626 I suppose, wouldn't know. It did have leather steering wheel and gearstick knob, climate control, 5spd manual (no LSD) and no cruise control.





So then I jammed it in my VW



I even tried drowning the motor, but the ZE loved it


Now, all my part numbers are as follows;
Model : EGE5B
Chassis #: GE5B-102239
Engine #: KL232729

ECU: KL36
EGI
KL31 18 811 C
079700-3613
2Z KL36D 12V

TB: KL30
195900-3611 3M26

VAF: JE50

Little ECU sticker=>


Now, I have a perfectly smooth idle, a smooth power delivery curve, pulls all the way to redline without flattening out in power.

I cannot find any set screw in the rear rocker cover which I could possibly unscrew to cause a vacuum leak.

I made new intake gaskets from gasket paper, because the ZE ports are different to the 03/DE ports. The ZE valve cover gaskets are definitely the same as the 03/DE gaskets.

A lot of people said I would have oiling problems from running the engine south-north, but I can say I haven't had any, even when it is at extreme angles offroad.

Hopefully someone finds that info helpful. There are a heap more pics and info on my website.

Nope, the KL31 and KL36 ECU's will work just fine with the standard KLDE distributor.



You will need the complete ignition system from the ZE in order to use the ZE's distributor.

Or you'll have to convert to an MSD ignition and coil (or similar brand) and use the ZE distributor.

ok so i'm new on this. I just found out about this motor and still don't know anything about it. I Have the I4 and want to put one of these motors in it. I found a site that has the motor and sells it for 1700 with the computer. is that good. and would it be worth it

[ODIN]

putting the klze into the I4 mx6 is TOO HARD. Major headache. Best thing to do is buy a v6 mx6 with a blown engine or buy a normal v6 mx6 and convert that

[Baja Wes]

My friend has just purchased an automatic MX6 front cut.

His chassis number is GE5B-100475, so it is an automatic 4WS MX6 chassis number.

His big ECU number is;
KL36
EGI
KL31 18 881B

And the little number is;
2Z KL36C

So basically we both have very early 4WS MX6 front cuts, one an auto, one a manual, and we both have KL36 ECU's.

I'm preparing a detailed guide to chassis numbers and cars with the ZE as well.

Just wondering, what does a ZE run the 1/4 in if you keep it near stock?

I believe over in Japan they ran ~15.1 in a comperably weighted car.. not overly impressive but about a half second faster than us here and remember that's on higher octane gas than we can get at the pump here in the US.

However, here, people who do swaps with it stock I would imagine running about a 15.0 or 15.1 on pump 93 octane. I assume that based on a lot of people having run their ZE swaps with just intake an exhaust pulling a 14.8 to 14.9.

Easybob...Would there be any difference in the swap of a KLZE with a 93 Mystere V6? Would I need more than just the engine and ECU???
