Just dyno'd the 1JZ!
Just dyno'd the Lexus. Made 263 horsepower & 275 pound-feet of torque. Only modification was a "test" pipe.
One interesting note. I left the stock fuel pump in place, based on a calc I came up with a while back on fuel requirements for my 7s. Sure enough, the AFR was in the 10s at 5800 and above. Looks like the stock fuel pump is sufficient for the 1JZ. Should be good for more boost too, considering that high rpms are more taxing to an injector than boost. I'm not advocating a stock pump at 14 psi, but 12 should be safe. We'll find out in a little bit here.

As for the dyno im so excited considering a stock RX-7 only makes about 250hp and your really pushing your luck on a stock 13b at 14psi. Also is there any tuning done on the dyno on the stock 1jz?

The "test pipe" was a one-off pipe made by a friend. Those numbers are at stock boost. I don't have any vids yet, but as soon as I get a new battery for my camcorder, I'll get some up.
