    I'd use the probes loom, I see no reason to splice it in, as it just runs from the engine back into the firewall to the ECU.



  • awsome thanks alot . ill start looking for a good donor car tomorrow.
    do you know anything about what i will need to turbo it (better pistons,cams,etc)or will i just need to buy a turbo kit?
    cheers

    100% no idea bud.. My mechanical is done by some ex RAF turned fork lift truck engineers from work.



  • cheers anyway . ill do a lil research



  • You have OBD2 loom.

    Well to be 100% correct in the UK the MX-3 never received a proper OBD2 loom with a proper OBD2 diagnostics connector. For some reason in the UK they kept with the OBD1 style diagnostics port in the engine bay.

    Basically in the uk you have the pre 1994 loom and post 1994 loom.

    The pre 1994 loom is plug and play, the post 1994 loom is not.

    If you have airbags and an immobiliser chip on your key its the post 1994 loom.

    –--

    All the info I gave you was for putting in a KLZE not a KLDE.


    If you plan on going turbo talk to MARCO on here he will steer you in the right direction as he's the most experienced.

    But if your going turbo you can probably keep your stock loom and as you will need to run megasquirt anyway to get it running decently. (run this buy MARCO)


    KLDE swap. (I'm no expert on this as never done so check what i'm saying against other sources)

    This is completely different to the KLZE swap.

    The problem with the KLZE is that the only ECU you can get to run them is only compatible with the pre 1994 loom so you pretty much have to use that loom if you want to go with a KLZE.

    But with a KLDE you don't have that problem as there are OBD2 ecu's for the KLDE. So you should be able to keep your loom and just run the KLDE ecu as long as its from an OBD2 car and use the KL02 VAF from the same car.

    Again run this by other people as I've never looked into KLDE's much.

    You need to check that the ECU will fit your loom as thats the part i'm not sure off. As said before in the uk the MX-3 never got a proper OBD2 connector, but I don't know if the uk probe and MX-6 did??


    I'd only consider a KLDE swap if your are 100% committed to going turbo, otherwise i'd go for a ZE.

    Also you have to ask yourself do you want it to be a daily driver?



  • im planning on using it about 3-4 days a week untill i turbo it , then it will become my "toy".
    i might upgrade the probe engine a bit , use some of the kl-ze bits aswell(manafold,etc) .
    ill have a chat with marco after i have the kl-de block in and running (one step at a time lol)
    might have to join a probe forum to see how they upgrade the engine the best ways.
    ill compare the probes loom plugs with mine to see if there all the same aswell



  • The main plugs will be the same shape, but that doesn't mean the wires go to the same placee.

    You need to get hold of the pinouts to be sure.



  • (just a passing comment)
    an mx3 is not the best of cars to use for delivery driving lol .



  • Hey, some advice from my experience :)

    Sounds like you're taking the right route, get the DE running well first.

    DEs take a turbo very well. I wouldn't bother upgrading rods or pistons etc unless you're going seriously over 300bhp, which is pretty hilarious fun in an mx3! Over that you get into gearbox problems, which would get very expensive. Stay under 300 and you can have a very quick car for not much money.

    Clutch wise I strongly recommend using a OEM daikin/exedy pressure plate and the ACT 6 puck from the old RX7. Holds the power no problem and very streetable.

    Fill your engine mounts at minimum with windscreen adhesive. The AWR engine mounts are very good though.

    Hopefully you can weld, as the ebay turbo hot pipes may require tweaking. For the money though they're amazing! Your cross member will require notching for the pipes too.

    Keep an eye out for a good wastegate like TiAL or turbosmart. I'd recommend 5-7psi to start. 5 is actually a really fun level, but boost is addictive ;)

    I ran an ebay t3t4, they're a bit hit and miss. Mine got smokey.

    There's lots of info on probetalk about boosting the KL. Megasquirt is the default/obvious engine management choice for KL builders, plenty of base maps online too. Though haltech, sds etc have been used too.



  • i can see why you have a mod squod star lol. golden advice and greatly apreciate it. im not the best with cars but i have mate whos done loads of engine swaps(but mostly vauxhall) like his 3.0 v6 corsa and 2.0 turbo nova etc . i will try and get all the parts you have recommended



  • next question
    wet float bearing vs ball bearing turbos . whitch one is best ?
    if im not mistaken bb turbos spool faster but apart from that is there much diffrence?
