Hi all, I am looking to get a set of the JUN 288/11.35 cams for my RB26. Anybody have a dyno sheet of these? Or any JUN cams vs. HKS or Tomei or Greddy cams?

TIA

tomei cams are the best of the lot that you listed, get either tomei or apexi.my car idles like stock with the tomei 260/8.8mm lift cams not too shabby of an increase over the stock 232/7.8mm stuff.

I always wondered what the specs on the stock cams were.

You have those in a 20 don't you? How/where did you notice the difference?

JUN is definitely good stuff... maybe check the aussie forums since they have a greater # of RB26's than we do...

im retarded but the correct cam specs are 240/7.8 for intake and exhaust on the rb20det.http://www.tomei-p.co.jp/_2003....html

rbsileighty - im not really sure where i gained or lost power with the cams because i threw on a big nasty turbo at the same time..........

i really need to tweak my cams timing tho because my spool time sucks absoloute ***, but its also proly due to leaky rings.....

Thank you, everybody, for the replies.

The car is at Alamo Autosports.

I have used Tomei cams before. And I know both Tomei and JUN are REALLY good. Both companies have done their research and development, so they make some bad a$$ stuff. But the JUN are way cheaper, so I'd rather go that route. Most probably I am putting a GT42R turbo on it, so I am not really concerned with the spoolup, just topend. Car should be build to rev to 11.5-12K rpms. So a nasty powerband from 5500 to 12000 should not feel that bad, especially on 18x12 wheels on the back.

Also, sorry for my mistake in the title, it is RB26, not 25.
