Not much of one, really; just swap the engine harness which pops through the firewall, and plugs into the ECU. It also has a few plugs by the dash to supply signals (and the OBD-II diagnostics connector) to some of the interior stuff like gauge cluster, etc.

The only PITA part would be removing the two nuts on the firewall that hold the harness in place IF the engine is still installed; I did it with the engine out, so no biggie.

We'll see if she runs next week, I'm still waiting on alot of parts to come in (brake rotors and pads, intake elbow, some other things), and just got my exhaust rewelded to handle the SS headers. I'm also still in the process of replacing control arms, swaybar hardware, SS brake lines, not to mention finishing up the ZE swap.

As a last note, you do NOT need MS to run your goddamn engine! What a friggin' joke, everyone that has one seemingly needs to justify their purchase by pushing it on everyone else. The stock ECU (even a '97) will run it just fine, you will lose a little bit of power because VRIS will be off, and your CEL will be on unless you install the EGR valve. But, it will work, and reliably so.

The OBD-I swap and an EPROM will allow you to get rid of both the CEL from EGR and correct the VRIS, without the expense and constant "tuning" of MS. I have nothing against MS, but let's be honest folks, it's not for everybody! Most people want to put their car together and drive it, not tweak it constantly.

Sweet. Thanks a LOT. I didn't want to get MS. If I was going to do a ZE swap I would just swap the harness since I would need the motor out anyways. Thnaks a lot for the info, I don't want to mess with MS if I don't HAVE to.

Let me know if your car runs, I would like to know of any problems or anything.

Also, willing to tell me how much you payed for the motor, ecu, ect.

Please people, more info and suggestions

the Greddy SP2 with the hotshot combo is sweet.. I actually ran a boosted MR-2 a few days ago, and the guy pulled me over after we ran ( no i didn't win.. MR2 had a JDM swap running 8psi).. He told me my car sounded pretty pissed off.. if you want.. go to streetfire.net.. type in klze.. you will find a vid of me running a KL03 6 in texas.. it sounds pretty mean from the inside.. don't know what it sounds like outside cuz i never let ANYONE drive my car!

So tell me why would you bother swapping a motor like the KLZE without trying to get the full potential out of it?? Joker.. talk to ZE powered MX6.. he has got a 96 m edititon with the JDM swap.

**JoKeR6** · 1-5-07, 10:19

can't find it t_dubb

**JoKeR6** · 1-5-07, 10:24

what would be the difference in putting the obd-I harness and MS, wouldn't it be the same as a 93?

**t_dubb** · 1-5-07, 10:37

Here it is.. not a very long vid, and it was nighttime in Dallas when we took it.. this is me pulling on a KL03 from a 60mph roll..

You gotta draw the line somewhere....I promise YOU aren't getting the full potential out of YOUR motor, MS or not. There is ALWAYS something you can do to get more power.

Alot of people swap in a ZE because the stock motor blew, I guess they shouldn't "bother" because they won't get the "full potential" even though it's already an upgrade over stock.

Point is, it will run fine on the stock harness and ECU. If he wants to MS it, great, he'll probably get 10 more HP out of it. If not, you make it seem like it just won't work at all. This is simply not true.

His original question was, "What do I NEED to install a ZE" not "what do you think I should get to get more power."

As for the OBD-I harness, you can then put in an OBD-I ECU with a ZE EPROM and not have to hassle with "tuning" it.

Cool, thats what I want, not to have to tune it, that is a PITA and I know NOTHING about it and want it to be reliable. And say 10HP doesn't mean [shizzle] to me. Honestly, I want to have a quick DD, I mean for the $ and the work for MS 10hp isn't that inviting.

I never said you will get the full potential, because that will never happen without the J-Spec ECU. Talk to mx6dave.. he did a ZE swap and if i'm not mistaken, he is running a slower time in the 1/4 now than when he had his KL03 slapped in. Like I said I'm not the ZE genius, but I do know that OBDII can cause problems when doing a ZE swap.

Joker6 - did u get to check the vid?

**JoKeR6** · 1-5-07, 18:33

well I dunno who is a ZE genius, wish they would post here, haha. If I will run a slower time with a ZE forget it then. Hmmm. I think we need more opinions

**t_dubb** · 1-5-07, 18:45

check the vid, look at the comparison.. IF that vid isn't enough to get you interested in getting a ZE, then I don't know what to tell u bro. It satisfies me well, especially for a DD.

If he ran slower, something else is wrong. Plenty (if not MOST) people who get a ZE run it with the stock ECU and have no problems. Their cars are most certainly faster than stock.

As for the ECU, that's why I recommended the OBD-I harness, ECU, and an EPROM. Perhaps you didn't see it.

The biggest point is you can always do the ECU or MS LATER, you don't NEED IT to make it work. I don't know why this is even being debated; that's not an "opinion," that's "fact."

**t_dubb** · 1-5-07, 19:47

Ok dog.. I was never debating anything.. I think I've owned a mx-6 long enough and read enough threads on this site to get a general idea of how the KLZE works in OBDI and OBDII cars. To each its own man...
