Will I need anything for the swap besides these items that are included when i buy the engine?
»Motor
»Engine Wiring Harness
»All required Cables
»ECU
»Distributor
»Complete Intake Manifold
»Alternator
»A/C Power Steering Pump
»All Brackets and Sensors

you wont need
»Engine Wiring Harness
»All required Cables
»Alternator
»A/C Power Steering Pump
»All Brackets and Sensors
»Distributor
the ones on your current klde will be compatable..

but "Complete Intake Manifold" whell most just go CAI..

theJspec ECU and VAF are a nice optional extra...
look ere..

Question is, do you have the I4 model or the V6?. If its the I4, put it in the too hard basket.

**Si[xXx]er** · 1-29-04, 11:49

Yeah, if you have the i4, you really "cant" do the swap. It can be done, but it would be way cheaper and less work to sell your car and buy an LS with the 03 in it already. You can also check out this link here:

The search function is your new best friend. There is tons of info on this site on the ZE, so take a look around, search, and you will find.

I was planning on using a V6 mX6 for my swap, i know the I4 swap would be way too much trouble. What is a CAI? And where would I find a j spec VAF? The motor I am buying already comes with the Jspec ECU.

**Si[xXx]er** · 1-29-04, 16:35

CAI is a cold air intake, you need one because the stock airbox setup on the ZE is different than the 03. As far as the vaf, I have no idea, sorry I can't be of more help in that regard.

If you run across any other acronyms on the site that you are unsure as to their meaning, check this out:

Most of the most common ones are in there.

if you are going to do an engine swap dont go to the v6 go to the 1.8jspec the v6 doesnt have alot of internal engine mods, and the max power is bout 380hp 312 torqu, 1,8 is about 400 w/o bottle

**Si[xXx]er** · 2-16-04, 19:35

Ummm, what 1.8 jspec engine are u talking about? An I4? If you have really deep pockets and you want that much power you can rebuild a KLDE, or a KLZE to handle massive boost and get just as much power. But three main quesitons still remain, which engine do you have right now, how much money do you have to spend, and how fast do you want to go?

im sure he knows this...but the guy above him seems to be talking about swapping the 2.5L v6 mx6 motor for the j-spec 1.8L v6...which seems kinda weird...

The klze is a bolt up motor to a 2.5L (KLDE/KL03) a-spec mx6. Everything works fine. If you want to make it run 100% that's a different story. You need to correct fuel flow, and VRIS. some people get fuel regulators, and MSD swithces to correct these...
the KLZE eprome chip is for sale in the bulk buy section at the top of the main page. Im not sure if the emprom chip requires the j-spec VAF. but it fixes the problem as far as i know

If it does require the VAF, just get one from a mx3 V6, they are the exact same.

hope we have helped you any. By the way, there is a KLZE FAQ thread, search for it...actually i believe it is a sticky thread for "2nd gen performance"

**sethbobbob** · 11-27-05, 11:44

did the klze myself
just turbo you kl03
I'm changing my pistons and boosting my klze next month

**mx6145** · 11-30-06, 13:15

so may i ask why is it so hard to swap the i4 with the klze n e answers? cuz my friend wants to do it to his 6 i4

**1<stockMx6** · 11-30-06, 13:26

Cause you have to replace basically everything under the hood. From the wiring harness to the exhaust setup. Even the engine mounts are different and located in different locations if memory serves correct.

**mx6145** · 12-5-06, 0:23

hmm... i dont think the engine mounts are different hmm.. im know the exaust will need to be redone and yes the wiring harnes needs to be switched i guess it will be an alright little challenge i try to post pics whenever we do it

**Trent** · 12-5-06, 0:28

as for the exhaust, all you need to change is the factory midpipe. the midpipe on the v6 is slightly shorter if memory serves. The engine will come with a new y-pipe, but i'm not sure how the muffler for the i4 would sound with the v6.

there are more parts that have to be swapped than you probably realize. Most people who do this recommend that you have a v6 parts car to pick apart as needed. I have owned both an i4 and a v6, and I can attest to the fact that they are very very different under the hood.
