The 2 main differences are; 1, that it doesn't need a gasket, so you can take it off and on as many time as you want, haha. 2, that you can clock the entire turbocharger on the manifold so you can position it exactly where you want it, no need to cut and weld the flange, etc. Plus it's just...
For any Supra owners in Alberta, feel free to stop by the Alberta Supra Owners Club forum, it's relatively active for such a small userbase.

The 1JZ R154 flywheel is exactly the same as a 7M R154 flywheel, just with the JZ bolt pattern instead of the 7M.
None of the W58 flywheels are the same.

Yeah, looks like Toyota was more consistent on the 7M than on some other engines. I've checked a few years of the TSRM and they're all the same.
They still do it weird on the 7M though, haha.
You'll need to get the numbers from the crank and rods to figure out what rod bearings you need...
toy fanatic78's specs are for a 7M I think. I assume you're looking for JZ values.
You didn't specify 1JZ or 2JZ, so here are the 2JZ values, I'd be surprised if the 1JZ is different.
Cam Caps: 14 ft/lbs.
Oil Pump: 15 ft/lbs.
Harmonic Balancer: 239 ft/lbs.
Water Pump: 15 ft/lbs.

Toyota has used more than 1 numbering system in the past, depending on what year you have.
What numbers are stamped on the block and/or crank (whatever is applicable)?
Jeff
The pressure relief valves are actually in the bolts, not the nozzles themselves. The bolts should be replaced.
The Supra in Japan never came with the 7M-GE. It had the 7M-GTE from the get go, squirter nozzles were added at the same time the 7M-GTE made it's debut here in North America. Same...
I've never seen a 7M spontaneously develop rod knock. Every single time it happens it's one of 2 things: low on oil, or coolant mixed with the oil.
Both of those are caused by owner negligence.
Jeff
What are you talking about? That wasn't the first time, that was basically the last time, F1 was in the USA for years and years before that happened.
If I'm thinking about the same time you are anyways, which I probably am.
