    MX32 Cressida Engine Conversion

    Ok, so I have an 80 Cressida that has 95000 original miles now and Iím looking to go with something more modern in the engine bay. Donít get me wrong, I have enjoyed the 4ME and it still runs strong, but it just is a dog for power most of the time and can be thirsty.
    I have been driving the 80 Cressida model since I was 15 and am 40 now and just ready for a change in performance and parts availability.
    I currently live in Utah and am looking for any recommends on shops that do conversions and do them right and what is an ideal engine set up. I want something I can drive for a distance and not have much worry.

    Option 2 is I pull the 4ME and take it to have it freshen up and same with the trans and just live with the blah performance.
    Love to hear what you all think and suggestions on shops that are in the surrounding states.
    Thanks,
    Erik

    i can respect that you know your limitations and you don't want to jump into swapping an engine when you know you'd be in over your head. not everyone has the natural mechanical ability to handle something like this, although if you have enough time and patience, it's not something that would be impossible to learn as you go and do yourself.

    i don't know of any shops in your area, but i do know that the 2jz-GE has been installed in the x3 chassis at least a few times. there's at least some knowledge available, and possibly some parts that cater to this specific scenario. check out a couple of the build threads in this section for other users that have completed their swap; Lloyd's is the first that comes to mind.

    i think that would be the best all-around choice from an availability and cost/benefit perspective, especially if your main gripes about the 4m come down to reliability, smoothness and economy.

    I have built street rods and have done a lot with british cars, but its just lack of a shop to work in anymore and the time. To be honest the 4me has never let me down and out of the 25 years of owning one I have had to do one head gasket. My current one is just tired and the seals are all dried up. It is time to go through the whole engine or get something modern. I guess I could sell it and go with something a bit more common and such, but I would sure miss all the good times and its cool looks.

    i have a 4m in the wagon i'm hoping to have pulled soon. it looks cool so i'll probably pressure wash it, drain it and pull the crap off of it, put it back together and build a display stand out of pallet wood. it doesn't belong in the car because:

    - it starts like shit if at all.
    - it gets horrible mileage.
    - it doesn't make enough power to keep up with modern cars.
    - it's expensive to keep maintained.

    even if i went through the engine at great expense of time and money, none of those issues would be resolved, just slightly improved upon. i'd rather spend that money - or less - and have something i can actually appreciate from the driver seat with the hood closed instead of standing in front of the parked car with the hood open.

    but don't let me detract from your enthusiasm in keeping it original, there's no problem with it as long as you can live with the obvious compromises.

    Ha, I get what you mean and yeah I am in front of the car often making adjustments here and there to the engine. Lucky for me I am a little OCD when it comes to my cars and I'm sure it drives those around me nuts. I really do just want to convert it at this point, I just don't want it apart for a long period of time. That is why I'm in search of those that have the time and want some extra money to do it.

    Thanks for the replies though and I really get what your saying.

    Does the 7mge require much in the way of engine mounts and trans?

    Hey, I resemble that remark! You haven't lived life if you haven't passed a chain of cars on a two lane road with a 4M...and Toyoglide! Better yet, make it a 2M! :shock:

    Kidding aside, 2JZGE's are now so readily available at relatively inexpensive prices (including whole cars). Seems the best route today for a good driver without investing too much.

    as far as i'm aware the 7m will bolt up to the stock engine mounts.. unsure on the gearbox mounts as it depends what gearbox you are going to put behind it. 7m's are definitely the cheaper way of doing a engine conversion.. and can still make decent power if you were to go down the turbo route in the long run.

    i would never recommend using a 7m. i'd stick with the 4m over it any day. especially one that's been cracked open.

    i'm not pulling the whole "BHG!" excuse out of my ass, but there's a laundry list of other issues with that engine that make it not worth pursuing. i picked up a whole ls400 donor car last weekend and i've started my swap. no looking back!
