    Engine Swap Info

    Hey guys, new to the site, but not to proteges....i'm a member at protegeclub.com and toprotege.com....anyways...

    I've got a 1992 Mazda Protege SE with the SOHC. I've got 300K on the engine and it's basically dead because of reasons which are too detailed to get into...

    i've been looking at the KLZE swap but i am thinking it will be too much money for me right now...i'm a student and i'm already in debt right now....anyways..i've come across a bpt and need to know what kind of changes will need to be made to my car to make it work....

    ..i've heard that the BPT has great potential....I'm thinking maybe look at the BPT and use my stock ecu for now.... i can always upgrade it later....and just find a tranny from a GT or Escort .... could i use the same clutch from the AWD tranny?

    A stock engine is gonna cost around $300 - 400 dollars anyways....so spend a few more bucks ($455 for the BPT ) and then say $350 for the tranny and around $400 on the install and few parts (cap, rotor, plugs, wires, filters, fluids,etc...) and i'm looking around say $1500 for a BPT...a lot better than over $3000 for KLZE with near same results....

    I'm in need of a new engine in about 2-3 weeks so i have to decide if i should go with the turbo or not...

    any input would be great

    Hmmmmm...didn't think about intercooler....that's something that could cost.. and the wiring ...i don't know

    Here is a link to the engine i 'm looking at...

    1.8 BPT

    "It doesn't look as if the piping or intercooler are there...HOw much would an intercooler and piping run?"

    *correction* It looks as if some piping from the turbo is there....i don't know if it is for the intercooler or not....

    Now.....if i decided to go BPT.....would it bolt right in to existing mounts? and would the tranny bolt in as well?

    Do i require the fuel pump to be upgraded....or is that something that can wait a little while..?

      You need to understand that the motor will most likely not sell for only $400 as there are 2 days left in the auction. Also, unless you are close and want to pick it up, shipping will be another $200-$300. Piping and intercooler are not included. You can get a decent intercooler from a Ford Probe for around $50 on Ebay. I even have one that I could let you have if you're interested. You can also look into a Starion intercooler but that would be a bit more expensive ~ $150. You will also need the piping which will be another $50-$100 depending on the intercooler you get. The motor will bolt right up but the tranny is useless as it is AWD. You will need to upgrade the fuel pump eventually if you want to run higher boost. When you add it all up, it'll definately be more than $1500.........

        I know not to expect the bpt for $500 but i'm looking at just ideas right now....

        HYPATHETACALLY...if i got the engine.....say $800... good....now new tranny and clutch from DOHC Protege or Escort...fuel pump can wait....till january... now i need intercooler and piping.....and to extend the wiring.... is that basically it?


        approximate costs:

        Engine - $800
        Tranny (used) - $200-300
        Clutch - $200
        Intercooler $150
        Piping $100
        Install (engine and intercooler) $500
        Basic Items (Cap & rotor, Plugs
        & wires, filters, fluids) $100
        --------------------------------------------------------
        TOTAL Estimated Cost $2050 CDN

        Does this sound a bit more realistic?

        I can do a fuel pump later on when i start working again (January) and i can upgrade the ECU when i find one... but other than that....it's a bolt in? No extra mounts, or cutting or relocating?

        My machanic is good...all payment under the table...he is a family friend... I will probubly help him in two evenings... to do it...

        Is there much else to know?

        or am i under estimating the job?

          Yeah, that's a bit more realistic but you're not including the Gtx Ecu, which is the biggest investment at around $500. You can probably run the car off an LX ecu, but boost will be very low and you'll probably need an AFC, which is about $200 from Ebay. In the long run, you'll need to get a fuel pump ($100), BOV ($55), Boost controller (manual- $70), gauges ($100) and I am sure that there are other things that I am forgetting at the moment. Add all of that and you'll be close to what it costs to properly run a fairly well boosted Gtx motor.

            from Protegeclub...








            read all those, come back with specific questions



            if you're on a budget, maybe look at a US market Probe GT or Mazda MX-6. Both these came with the KLDE, the 165 hp/165 lb-ft version of the KL. A lot cheaper.

            For trannies, ANY of the K series trannies will work. The MX-3 has the shortest gears, and the 626 has a long 5th. A hybrid would be optimal, and has been done, but not for your budget right this second.

            For the ECU, the oem MX-3 one will work, but isn't the best. Find a JDM KL-ZE ECU. The VAF that the MX-3 uses is the IDENTICAL part number as the KLZE piece, so don't worry about it.

            you'll need axles from a MX-3, and the lower crossmember, and motor mounts, but other than that....it fits into ANY BG series car.


            Basically, find a wrecked MX-6 v6 as a parts car....and sell off the stuff you don't want.

            Personally, I like the KL over the BP. But that's an opinion. Make your own given the facts.

                not a bad idea when you consider 125hp vs 165

                      Well, in relationship to the above posts, it's the name of the company in Canada that'll do the KLZE engine swaps into our cars.

                            Well...I've done some figuring and made a few calls... i think that due to my budget a BPT isn't in the works

                            ...BUT... I can afford to do a straight SOHC to DOHC swap...and i've even found a motor.... I'm curious as to what parts i will need off of the car i'm taking the motor out of....Which of these parts do i need to keep from my SOHC and which do i need from the DOHC:

                            Drive Axels?
                            Motor Mounts?
                            ECU?
                            Wiring Harness?
                            Clutch?
                            Tranny?
                            Fuel Pump?


                            On my SOHC my tranny and clutch and driveaxels are all brand new so if i can use them great...if not..i'll sell them....but i was wondering most of all about the SOHC Tranny...I would like to keep the longer gears of the SOHC for my DOHC Engine...but i don't know if it will a) Fit? or b) Handle the power? Anyways....if anyone has done the switch and has some advise or instructions or hints or found any problems that i would come across while doing the swap...please let me know....i'm looking to do the swap in 2 weeks...

                            thanx

                              good advise.... i bought a new clutch a month before i lost my licence so the clutch it new.....but it's a cheap clutch....will it stand up to the power and torque?

                              so i can use my SOHC tranny then ...for sure?

                              my flywheel is good too..and drive axels are new.....so if i can get away with that ...great...i'd love to have the long gears with the strong powerband...

                              the flywheel mounts to the DOHC fine...with no mods?

                              and what about the wiring harness and the ecu...are they the same SOHC to DOHC?

                              As well...what do you think the torque loss would be if i used the SOHC tranny with the DOHC motor?
