The twin-turbo 1JZ-GTE. Although rated at Japan's self-imposed maximum rating of 280 hp (206 kW), this was probably quite conservative. A later unit (with VVT-i and a single turbo) probably produced well more than 300 hp (221 kW). Torque was rated at 278 ft·lbf (376 N·m) at 2400 rpm.

378= 278.76lb/ft
376= 277.29lb/ft

I'm a little suprised at how low the tq comes on. Makes the 1jz even better imho.

oh no im not looking for the torque spec on the performance of the motor. im looking for torque specs for torqueing down the bolts. like torqueing down the bolts that holds the cams, torque spec for intake and exhaust manifold.....etc.

oh... ill look it up on alldata tommorow if you want. Not sure how close I will get, might only be able to get the torque sp[ecs for the 2jz-ge and the 2jz-gte. Hopefully they wont be different.

thanks. let me know when you get the specs.

I was looking over it the 2jzge and 2jzgte have diofferent torques fro some parts.

I tried to link to it but apperantly i cant link outside.

I'll have to go in tommorow, take screenshots and then upload them 1 by 1 into imageshack. May take awhile.

What are you looking to torque down specifically? Do you have a torque wrench to measure the torque being applied to the bolt you are tightening?

blaznsc4

yes i have all the necessary torque wrenches ranging from 50 ft.lbs to 300 ft.lbs and 10 in.lbs to 100in.lbs specifically camshaft bolts that hold down the cams, cam gear bolts, crankpully, etc.
