    Question 5MGE into MA61 (changed from 7MGE)

    I need your help guys, I'm trying to weigh up whether it is worth getting an old 7M, re-doing the head/gasket, replacing a few other misc things and using that or whether I should grab a 2J and shove that in their instead. It will be for my MA61 supra.

    I can get the 7M conversion done by an acquaintance for $2k if I supply engine (~$500 but then I need more for re-doing head and other things). 2J might cost me $1200 with ecu/loom but then I'd need more things like a W58? I'm not after massive power or anything turbo, but I would like a bit more than the crusty SOHC 5ME puts out

    Tell me the pros and cons and which way you think I should go and remember, it's always on a tight budget. Thanks guys

    Don't get a 7MGE as their head issue is not worth solving. The amount of money you spend on the 7 to fix the ongoing head problems is far better being spent on the 2J

    Its only an ongoing problem if its not fixed properly the first time at which point you must question said workmanship on the car. .

    Depends on your driving style really do you like an engine with a punch in the guts off idle, or do you prefer to rev it out .

    That being said, the 2jzge is a newer motor, has more power out of the box so you are really only ever playing catch up with the 7mge. They still aren't a bad engine though.
    If in doubt power out

    This is me. I own an MA61. With a 7m, I still own an MA61 I like to keep it within the family.

    Go the 2JZGE. Aside from a smidge more bottom end, the 2JZ owns and only has more potential. If your car is a manual, all you'll need is a clutch/bellhousing/flywheel etc. Yes it will cost more, but it will be a better result.

    2JZ-GE. Do eeeeeeeet.

    I was in the same situation. I could go 7m and not worry about engine mounts, bellhousings, etc. But I realised that the 2jz is a newer motor, and once I got it sorted, if I want to go turbo.... 1jzgte or 2jzgte are not too hard to swap. Also aftermarket parts availability is slightly better. Even oem parts availability is better.

    wayne just pulled 137rwkw out of his 2jzge and that is factory with bolt ons!!!

    Want to make that power from a 7m and you need to open the thing up with some serious work!

    Here is my website when i did the conversion a few years ago:

    go the 2j!

    from economical point of view i think they are more fuel efficient too, so you would make up for the extra cost in the long run.

    Before microleb I got 10L per 100km on the 7m on city driving too. Post microleb it gets 12-13L per 100kms, but I think I sink the boot abit more and it could do with some fuel being taken out.

    The microleb economy should own factory economy if its tuned right.

    Problem is you CANNOT tune that on the dyno.
    You need to do it on the road.

    i think the 2jz is the go. where's the poll

    sure the 7m would be easier to do, but the 2jz has similar or better economy with more power. nuff said

    Going by the parts on this page, http://www.geocities.com/ifli4u/project2j.html , it will prob cost me $3000 and that's just parts and using my W57. I have a heavy duty clutch and new slave cylinder, would prob replace the master though just incase. Anyways, 3k plus 2k for the actual labour itself is a lot more than I have right now If it's gonna happen it would probably have to happen a lot further down the track when I can have a second run about car and have the MA61 off the road for a lot longer.

    so why don't YOU do some/most/all the labour? it wouldn't be that hard if you can weld, undo bolts, and use your noggin good
