Engine Swaps

    I'm putting a 95 Dodge Dakota engine in my 92 Dodge Dakota what wiring harness should I use 95 or 92? and what other problems will I find? :confuse:
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 56,784
    You'll probably have to use the '95 harness and computer. I don't see how you can avoid this. You have a job on your hands, too. Always use everything from the donor vehicle in an engine swap unless of course they are identical cars. Even then....

    Hey everyone, im new here and have a quick question...has anyone ever taken a 3800 motor from a newer (90+) car and put it in a rear wheel drive car? If so how much did it involve?

  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 56,784
    Here's a guy that is putting one in a Toyota truck. He also gives you an idea of costs and labor involved.

    thanks for the reply...the 3800 im talking about though is the SFI series I out of a 92 Pontiac though, but i think the trans's may still bolt up to both so ill use some of that advice i think. Thanks for your help!

    How about an LS67? (Did I get that # right? The SC engine?)

    I have a 1985 Camaro with a 2.8L V6 and 4-speeed automatic. I would like to replace the engine and transmission with a 5.0L V8 and TH350 from a 1976 Camaro that I also have. I know I can purchase a B&M conversion kit for mounting the transmission.

    What other issues will I encounter? I know the radiator and supports will have to be obtained for use with a V8, but I don't know the differences between the 305 V8 from 1976 versus 1985. Which car should I use the power steering pump from? How about the belt driven versus electric fan for the cooling? Also, the 1976 car does not have A/C, and I am debating whether or not to remove it from the 1985 car also.

    The 1976 engine has a mechanical fuel pump, but I believe the newer ones had electric pumps back in the tank. Can the electric pump feed the mechanical one?

    Also, the emission equipment will be totally removed. What about the computer in the 1985 car?

    Well this is going to be a lot of work, and since I don't think many people have done this, you should really search out a "pioneer" who has gone before you and ask them what they ran into.

    One snag I can think of is that your car will be totally illegal regarding your state's emissions laws. You aren't allowed to "downgrade" a car by installing an older engine, and you '85 falls under all '85 laws, not '76 laws.

    I think you're pretty much stuck with using the accessories off the '85 but I doubt everything is going to bolt up to the '76 block so you'll be doing a lot of fabricating on this job.

    ANY engine can be put in ANY car with time and money.

    I'm wondering if you wouldn't really be better off finding an '85 V-8 car and building it up to the way you like it.

    I originally wanted to restore the '76 car (given to me by a relative), but the frame is too rusted out in the back. It has very low mileage (about 60K). I got the '85 car really cheap on ebay, and it was local. Currently, there are no emission laws in my state for cars this age, so I don't have to worry about that.

    Since my setup will be using a 305 V8 with vacuum advance and TH350 with vacuum modulator, are there things I will want to disconnect with the ECM? Not sure how much it controlled on '85 models.

    Also, I do not believe that my block should be any different than a newer one, so the motor mounts and the accessory brackets should be the same. Please let me know if you know differently.

    I plan to use the alternator on the '76 engine, and I was also going to use the power steering pump from that car also, and reconnect the hoses to the '85 steering gearbox. Do you agree with this?

    If I install headers, should I install them before putting the 305 into the '85 car?
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 56,784
    Well I think you'll have to rewire the entire '85 car. None of this stuff is going to work with your '76 engine and transmission, which will be controlled mostly mechanically I presume. So you'll have to figure out the charging and ignition systems based on how the '76 used to work.

    The blocks might be the "same" but I'm sure not all accessories go in the same holes...if you are lucky you'll find the right holes, but GM was always switching alternators from the left side to the right, or pumps this way and that.

    I'd use only the '85 steering components complete unless you are going to swap in the '76 complete post and box. You can get into very weird stuff by using a box from one car and a ram and steering arms from another....they aren't engineered to work together.

    The way you are doing things is kind of backwards I think...swapping an ancient technology into a more modern car...most folks these days are doing the opposite, which is a lot easier in some's easier to upgrade on old car than to downgrade a modern one.

    does that make sense? Hope so.

    Yes it does, unfortunately, and now I am getting cold feet about this. I think I will put the cars side by side and see how the routing to all the devices compares. I will also try to get some pictures of how the 305 V8 looked in a 1985 car. Thanks for your candor.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 56,784
    Well I don't wish to discourage you, just encourage you to plan ahead and take the time to do your homework before you jump in. From my own experience, I recall how discouraging it was to get into a project and slowly come to the realization that I was in over my head, and that I couldn't go forward and couldn't back up.

    it's not good to find yourself without options. When it comes to engine swaps, information is the best tool in your toolbox. You can save DAYS...of knuckle-busting work by planning your method of attack.

  • i have a 05 jetta gli 1.8t. its not fast enough 4 me. i was wontin to turn the turbo boost up but i dont kno how to. i know i should get the chip but i dont want to void the w. anybody know how to turn the boost up, please let me know. and if you have any other ideas how to make if faster let me know!
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 56,784
    You need a boost controller, there's no other safe way to do this. You have to know what's going on because not only the amount of boost but the duration of boost is critical. And I don't see any way around the warranty either. My advice is if you want to go fast, do it right and don't try to play both ends...either give up the warranty or give up the idea of making this car fast==you can't really have it both ways and feel good about what you are doing for yourself or the car, IMO.

  • I'm researching a project that I am working on and hope somebody who has done it or somebody who is pretty familiar with Fieros can give me some information. I've got a 1988 SE nothback that is going to be the victim of a transplant. I aquired a TPI 305 from an IROC-Z28 Camaro and have located a kit to install it(The V8 Archie Kit). The kit uses the stock fiero transmission (which is strongly advised that you strengthen). My question is about making that transmission (its an automatic) capable of handling more power. I have been told that there are newer transmissions that would bolt directly on to the fiero with little or no modification. But which ones? From which vehicles? Thanks in advance for any questions comments concerns or complaints.
  • :confuse: Anybody have any insight to the fiero transmissions? It may be easier just to grab a Northstar out of a caddy in a salvage yard. Its common to do that with this type of engine swap, but I was hoping to maintain the stock transmission and axel setup. That would really save me from having to custom fabricate more mounting brackets generally make the process smoother. That also raises the question of having the ECU to control the tranny... Any help?

    I bought an 85 S15 Jimmy and I am looking to restore it but I'm wanting to get away from the 2.8L that is currently in it. What I'd like to know is could I squeeze a 5.7L or 4.3L? If any has done this or knows of anyone who has let me know. Thanxs!!!
  • greg48336greg48336 Posts: 4
    Since the engine and tranmission are the "old" style, they obviously will not require signals from the '85 ECM. How can I find out what the ECM controlled in 1985 besides engine and transmission features, assuming I need to keep it in the car at all? I do plan to rewire the engine compartment of the car, or at least strip out what I no longer need there.

    Also, I need to try to find the wiring diagram for the '85 V6 car, so that I can label the wires as I disconnect them. Any ideas of a source for this?
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 56,784
    Damn....there is a website that carries wiring diagrams but I just can't think of it. I just e-mailed you the address of one of our visiting techs and he might know.

    Hey all, looking to do an engine swap on a '95 Eclipse. I was told that the 2.5 Avenger engine would fit ... but I'm not so sure how much I trust that particular source since he was the one trying to sell me the Avenger engine. Anyway, long story short: anyone heard of this before? Or does anyone know of any other simple engine swaps?
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 56,784
    I'll tell you my rule of thumb on these kinds of "unusual" engine swaps. I would NEVER attempt this without talking to a "pioneer", that is, someone who has gone before you and done the exact swap. This will probably require you expanded your search beyond these boards but check in with us and maybe somebody knows something more.

    A person can put just about any engine into any car with enough time and money but I sincerely doubt this is your plan, and I also doubt that we are talking about a "bolt in" kind of deal.

    Maybe you need to do a 2-step investigation, can you even put the Mitsu V-6 in your car and how much trouble is that? (I assume you have a base 4 cylinder engine in your car) ....then you can maybe figure what Dodge has done to the Avenger set up to change it from the normal Mitsubishi V-6 installation.

    Also, not to be discouraging I hope, your car isn't worth a lot of money so anything you spend on the car will not be recovered when you sell it.

    I have a '96 escort and want to do a engine swap. what is the biggest(most powerfull) engine that will fit without alot of custom work?
  • I own a 1984 533i BMW with a quirky motor and trans that's going out. But I also have access to a 1995 5 series motor and trans with all accessories for $700. I was wondering how hard a swap would be to put the '95 motor/trans in my '84. Will it fit without too many mods?
    Thanks for any help you can give me.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 56,784
    I think it would be a daunting engineering task and you still wouldn't have a car worth very much when you were done. You'd be much better off just rebuilding your stock engine and if you wish doing some exhaust and cylinder head work to it for extra power if you want it. A '95 motor would need all its computer controls to say nothing of all the mechanical modifications. You don't want this kind of Franken-car.

    Hey fellas, i got a 94 nissan altima. Have no clue about this kinda thing. Was hopin for some suggestions I could look into for an engine swap. Want real good acceleration from 1-60. Any suggestions would be great.
  • bumpybumpy Posts: 4,435
    There are a few different ways you can go.

    Turbo the KA24DE. You'll need to find someplace with a good reputation to do this, since the engine will need internal work and tuning.

    Swap in an SR20DET from a U13 Bluebird SSS (Japanese Altima). You'll want the whole front clip to get the radiator, motor mounts, and other parts; and you'll need the tranny from an SE-R or G20 since the Bluebird AWD tranny won't fit in the Altima.

    Swap in an SR20VE. You'd still need the Bluebird clip for parts, but you might be able to get a clip less motor and tranny. Add the VVL motor and SE-R or G20 tranny.

    Altima swaps are fairly uncommon since most Nissan performance of that vintage goes toward the 240SX (rear wheel drive), Sentra (lighter and smaller), or G20 (already has an SR20).
