Hello Ian,
I have machined the late 7M block and wile they are being machined you can see the differences. My machinist praises the JZ blocks and wonders why the the 7M was not made like it.
The rods on the 7M are weak. When I had my 7M it was a good rebuilt. one of the rods opened up...
HP and torque on the yellow boxes are with low compression on two cylinders. HP and torque in the green are with a helthy engine. Same mods two different engines. The lower HP engine had detonated and took two cylinders with it. faulty fuel pump is to blame. No torque claims are stupid. I drive...

The biggest give away that it is an Aristo ECU, is that plug that is cut from the harness. The plug is always part of the engine harness on Supra engine harnesses. and that ECU is from a Aristo like most have said.
The Main reasons why companies dont make Anything for our cars is this attitude. If it's a replica and it looks close to the original is ok to use. The chinese are good at R&D (Reserch & Duplicate) and that is the easy way to make a buck of some poor kid. When the car is on fire due to a fuel...
I have to add my few cents in this one, because I see alot of oil talk all over the place on this forum, and I was waiting on someone to mention this oil. I ran this oil on my last 1jz for almost 150,000 miles. I blew the engine do to overboosting. But I have pictures of the engine bearings...
