    I've considered a few swaps lately and I think the 7MGE seems to be the best. 2jz and 1jz are too expensive and the turbo 7M's are a bit harder to find than the N/A ones were I come from. I've located a local 7mge with a recent rebuild as well as a transmission both for $750. My goal is to have about 200whp. I like this route because the 7mge is suppose to still be fairly good on gas. I may also turbo the engine later on in my trucks life. Any input or ideas???

    Thanks
    Paul

    Go 1uz. Only 650, comes with a transmission, you'll more power and its lighter. They are great motors and the fitment will be easier. The 7mge will be a waste of your time, trust me on this.

    I've been considering the same thing, but I haven't been able to find out much info as far as how complicated the swap can be. I myself want to go turbo however. I've found a few on the net for around $900. Maybe your thread can help us both out.

    If you guys have a bunch of questions about doing a swap. Just give me a call, I'd be more then happy to help you guys (209) 250-1165

    Doing a engine swap is not that hard. If you are going from a Carb-to-efi, you'll need to combine your stock harness with the new engines harness. Sean @ MyJZswap.com can do that and save you the headache and time. You'll need new mounts, possibly fab them but, If you are local (or willing to ship your vehicle) check out this thread as this is something you might be interested in.

    Also you'll need the driveshaft modified, and re-route/ make new lines to whatever is needing to be connected to the new motor. Pretty straight forward just takes patients and time.

    I think i'm going to buy the rebuilt 7mge and just mate it to my stock 5spd with a supra bell housing. When the 7mge was rebuilt, it was rebuilt with future boost in mind so the lower comp and forgies should work quite well if and when i decide to boost. Once I complete this swap (hopefully for 700$) im probably going to slowly start locating the required parts to boost my 7m. (possibly from a complete wrecked supra). Including the supra tranny.

    Any input or ideas would be greatly appreciated!

    Thats basically the route I want to take. Only I was going to use a 5M head and pistons (different valve notches) on the 7M block to be able to carb it. Since the 5M can use the pickups stock ignition system fired from the supra dizzy. Since 5Ms still used a simple ignition, not crank triggered like the 7M. Although the 7M head has much more potential.

    if your gonna take the time to do the 7M swap, spend the extra money and get a 7M-GTE. You wont regret it i promise! :D

    Arent 5m mounts on a 7M motor make it bolt into 22R perches?


    One more question, What are the sump configurations availible? Front for supra? Mid or rear on anything else?

    I asked before and would like to be sure, but are 5m,6m and 7m bellhousing patterns the same?

    I know little on the strait 6's...

    Bellhousing patterns of those are the same. But I am unsure about the pattern of the older motors than that.

    The cressidas were the only other USDM vehicles toyota offered with those motors. From what I remember, the cressi has a different pan. I don't know which one you'd need. 78 Back frames a mid sump works I believe.

    The bores are the same, stroke is different. Thats where the difference from 2.8l to 3.0l occurs. You can use a 5M head and pistons on a 7M block for a "stroked 5M". They are a popular combo for the increased torque. Toyota did that combo and called it the 6M, but not many if any were sold in the US. 5M head is a DOHC 12-valve setup, and run a distributor triggered ignition. The 7M head is a DOHC 24-valve setup, and run a crank triggered ignition.

    In my case, I want an all motor setup with carbs. I like carbs. I can tune them well. I don't want to redesign the chassis to hold and plant the power a turbo has. Plus they require a new fuel pump in the tank, and more wiring. Plus, how often do you see a triple carb 5M swap? :D

    OK need to clear up some issues. I've got more than 1 cressida and have done a little (HA (sarcasm)) work with the engines. also have a 5M-GE(T), 7MGE, and 2JZGE sitting in my garage.
    -the 5m, 6m, 7m head/piston stuff is correct except toyota only used the 6M a year or two and only on MKII celica supras in japan only.
    -BOTH engines ignition systems are triggered by the distributor (as are some early NA 2JZ motors. that distributor is actually identical to a 7M one, I've got both) However the signal rotor is different between the 5M and 7M/2JZ
    -all M series engines have the same bellhousing pattern.
    -M oil pans are available in mid and front sump configurations.

    I'd Suggest a 5M. first and foremost, the exhaust note sounds better from the 2 valve head. then theres the fact that a properly broken in 5M will outrun a 7M, I've seen it happen more than once. If you're going turbo, you can use either a thicker MHG to lower compression or 7M shorter rods.

    I built my spare 7M motor at school (which I now consider stupid for a couple reasons) and was considering putting it in my 91 but after some measuring the crank pulley will exist at the same location as the radiator...slight problem ya? so I think I'm gonna put that in the cressida and put the 2JZ in the truck. I'm planning on using the front sump version.

    I'm pretty sure the 5M mounts won't work with the truck, the angle where it mounts to the body is MUCH steeper on the truck

    I'm in the same boat as you except I want a 7mgte but the more I read about the 1uzfe the more sounds like it would be a better swap but have no idea what I would need to make it work in a 22re 2wd truck. 275 ft lbs of torque stock doesn't sound too bad and you can get the motors in 300-400 range
