R154 Bellhousings

[ToranaJudd]

How do i find out the difference between a 7mgte bellhousing and a 1jzgte bellhousing assuming a r154 gearbox is used?

Is there distinct external features or just bolt pattern differences?

Cheers, Judd.

Also, Can i determine this by the R154 gearbox that came off the bellhousing?

Stampings, marking etc etc?

Cheers, Judd.

Toyota has ahabit of casting numbers on things, have a good look all over bellhousing and you will probably/may find engine series cast on to bellhousing.

M series R154 bellhousing is 196mm long
JZ series R154 bellhousing is 171mm long
Both M and JZ series input shafts protrude 190mm from the bellhousing to gearbox mating surface
So without a measuring tape and purely by the naked eye, if the input shaft protrudes past the bellhousing to engine mating surface it's from a JZ series engine and if it doesn't protrude, it's from a M series engine.
Also looking from the front of the bellhousing, M series has starter in about the 1 o'clock position and JZ series in about the 2 o'clock position.

R154 boxes from about 1995 onwards will have a remote shifter as well.
