    BMW 3 Seires 2JZDET Swap Insight

    I'm new here and I'm trying to get a little information on how difficult this swap might be in a mid 90's to late 90's 3 series BMW. The deciding factor, I think, is if I can find any information on splicing the ecu in. If anyone has any insight, I would appreciate it.

    (Flame suit on for not finding much in the search)

    No need for a flame suit.

    Are you trying to do this swap on your own? This swap has been completed into E36's successfully.

    um. 2JZGTE? Or a SR20DET?

    I think there are people who have done both..at least I know the 2JZ has. The SR20 only makes 200hp so I dono why someone would throw that in.

    2jz swap. I have the resources and know how to do it myself so I think it will just be me and a friend working on the build. I like the 2jz, they are just so easy to make high power on. I'm fine with a dyno queen if it comes to that ha ha. They make a mount swap kit, so that shouldn't be a problem, my main concern is wiring. I could figure it out, but I would prefer not to ha ha.

    Thanks for the non-flame. Im used to Nasioc (Subaru site) where the flaming is intolerable.

    If you are using the 2JZ wouldn't you just put the harness and engine in and bolt the ecu down inside the engine bay or to the passenger floorboard? I don't see why you would have to splice anything.

    What do you consider easier? Piecing together a bunch of random parts and trying to tune it, or swapping an entire engine and harness that already have tuning and hardware figured out?

    The engine itself can't tune itself ,You must tune it

    Huh? Usually people buy preset tunes, or go to a dyno and have somebody else tune it. The 2JZ has tuning hardware already figured out. I'm not sure what is out there for the S52.

    Being that the 2JZ was built for boost, you would basically swap it in with its own harness and then modify it as if you owned a 4th gen Supra.

    If I do this I swill do a full engine/ tranny/ harness/ ecu swap. Im not concerned with mounting the ecu (I had bad wording), but splicing the Supra ECU with the BMW wiring such as gauge cluster, etc. I am pretty proficient in tuning so that is not a problem. I will probably use a AEM EMS if I can get my hands on it for that year/model ECU package.

    I'm also concerned with modifying the stock clutch assemby to handle the 6 speed. Are the BMW slave cylinders pretty hardy?

    I've only done same manufacturer swaps with engines near the same year so I've never tried splicing in a different gauge cluster. Let us know if you find any info!

    Will do. Im interested in the BMW swap at this point, but if I can't find much information and don't feel like figuring it out, I'm going to go with a Lexus IS300. If I do decide to do it, I will definitely do a write-up.

    We have a guy here who just completed this swap into an E39 but he had E-shift performance do it. You might want to look at his thread in the S62 section.

    I have seen some SLEEPER is300 setups. Like 600whp while appearing stock. (except tires) And it is the easier car to swap a 2JZ-GTE into, or even turbo the 2JZ-GE that comes with it!

    Thanks guys. Yeah, the IS300 would be easier, but I like a challenge too ha ha. I'll check the thread out.

    Good stuff, but why were you post whoring the other day? E-mail me administrator@bimmerboost.com to discuss getting your limitation removed.

    I think I've made my final decision. I will be getting an E36 vert and dropping in a 2jzget w/ a w58 5 speed tranny. I found a couple of places that I can buy motor mount adapters, converted driveshaft, and ecu harness adapter if I need it.

    Good luck with it, that is going to be a hell of a build. Not easy at all though...

    Make sure you update us on how this progresses.

    Ask this question in the S50/M50 engine section.
