I did the swap myself...total cost including all new parts was around 3000.

Josh, you dont need the V6 axels. The inline4 axels fit just fine, except that they are thinner... but the 2.0l turbo guys dont seem to be braking the 2.0l axels, so they should do fine on the 2.5l. Well they seem to be holding pretty good on my KLZE

Possible? Anything is possible.

If your question is, "does it fit with relative ease (such as a KLZE swap)?", the answer is definately no.

if fabricating motor mounts and axles is one of your specialties then a 1gen swap would be easy

[FL_2G_Mx6]

ill prob end up goin to the junk yard or somethin and gettin the motor and tranny and rebuildin it and then pay someone to do it i would jus go ahead and throw a turbo on my 2nd gen but i wanna make sure the motor will be able to handle the turbo and not blow up on me

[FL_2G_Mx6]

come on dont tell me im the first to think of this i know atleast one person has attempted to do this if someone has done this e-mail me please lemme know how it worked and how much it costs

[mm2587]

oh its been done before, actually I believe it was an Fe-dohc (fe3) but its not easy and very, very expensive.

[FL_2G_Mx6]

o yea well lemme know some good sites to find jdm motors cuz my boy was tellin me they make a turbo jdm motor for it and i wanna check it out

[lorenzoOKC]

yeah i want to buy the klze motor i have the i4 which tranny would you recommand the j-spec or the a-spec

[Ms.OwnYoAss]

do you have to get a v6's computer?

[devious6]

sell your i4 and buy a v6 youll spend way more to put in a v6

Since there are all the I4-V6 threads that are posted all the time I figure its about time to sticky one with all the needed information. Here is a list of EVERYTHING you will need to do for this swap.
Before you EVER consider this swap, make it easier on yourself and buy a donor car( V6 MTX GT). You can find one cheap with a decent motor but maybe a trashed body.

Prepping to remove motor

1. Unbolt the exhuast from the header ([2] 17mm nuts)
2. Remove header ([8] 12mm bolts [2] 12mm nuts)
3. Remove hood ([4] 12mm bolts)
4. Unbolt front motor mount from crossmember ([2] 17mm nuts)
5. Unbolt lower tranny mount from crossmember ([2] 14mm nuts)
6. Remove subframe support and crossmember ([8] 17mm Bolts and [2] 17mm nuts)
7. Remove "chair" bracket from rear "transmission" mount and transmission ([3] 17mm Bolts and [1] 17mm nut attached to mount through bolt)
8. Remove rear "transmission" mount ([2] 17mm nuts [1] 17mm bolt)
9. Unplug all electrical connectors from engine wiring harness.
10. Remove A/C compressor hoses ([2] 12mm Bolts)
11. Remove power streering pump hose ([2] 12mm Bolts) ([1] 10mm bolt on Valve Cover)
12. Remove passenger side and drivers side axels ([2] 1 1/4 Hub Nuts)
13. Attach engine hoist to engine hooks
14. Remove passenger side motor mount ([1] 17mm Bolt)
15. Remove drivers side motor mount ([3] 17mm nuts and [2] 17mm bolt)

Motor/Transaxle removal

1. Remove the 2.0L motor and transmission.
2. Remove the main engine harness (you must remove drivers side fender, harness goes through frame infront of the door)
3. Unplug all engine harness connections under the dash
4. Remove the interior dash
( Note: does not HAVE to be done, but makes things easier. If you are a 2.0L ATX swapping to a 2.5L MTX then you MUST remove dash to install pedals)
5. Unbolt ECU harness from ECU (10mm bolt)
6. Unbolt the ECU
7. Remove the ECU harness (harness that goes through the firewall held inplace by a large rubber dust boot)

Repeat all previous removal steps on the donor car

All 2.0L and 2.5L motor mounts are interchangeable EXCEPT Automatic model front mounts are not compatible on Manuals)

Repeat all removal steps in reverse to install the new V6 motor and transmission

That was on probetalk.com, you just copy/paste all of this. And guess what? It not all and some of the thing mention here are not to do or change. I've done a I4 to V6 KLZE swap in my drive way with my father and it not that complex. A LOT of [shizzle] are behind said like: buy a LS or Damn this swap is [fizzle]ing impossible or to expensive dont even try to do it. Guess what...it all bull [shizzle]. Of course doing all this by yourself is not that easy but compare to someone who want to change V6 KLDE to V6 KLZE, it not a lot more job to do. In fact...it praticly the same except for 2 or 3 things to change. In my case, doing all this with a donor car that a buy 1300can give me at the end 300$ and more by selling part on the second car. And im really happy with my klze now and paying I4 insurence
