Hi this is probably for giant tomatoe but basically i have fitted a 264 9mm lift cam on the intake and seen a 10 rwhp increase in the mid range but the top end stayed at 206 rwhp, i am wondering what would be a suitable profile and lift to match this on the exhaust side.

The exhaust cam is a different story. There isn't an off-the-shelf aftermarket exhaust cam for the 2jz-ge that has the distributor gear. You'll need a regrind for the NA motor plus springs, retainers, and lash caps.

If you find an aftermarket cam with a distributor gear, however, let me know. ;)

Zohair and myself are trying to get Crower to make some cams for the GE. We'd like to get a large quantity made so we'll have them. We're thinking 256, 264, 272, and 280's. I myself would be using the 280's on my All Motor Project. As far as lift goes, 10mm would be the most.

Who did you go with? If you went with Crower, then they will be fine. Just have to get a valve adjustment.

I'd use exactly the 264 9mm profile on the exhaust cam. I wouldn't go for more than 9mm lift with an unported head - the head flows don't improve much after 0.200" (5mm) lift in the exhaust port so you're just wasting your time. However, if you were ever to port your head, you would definitely reap the benefits of the 264 9mm cam.

Here are the port flows for the 2JZGE head - feel free to print this and show your cam grinder Mos. I think they would be better qualified to give you this sort of advice than me.

Flows were done at 10" water vacuum.
