I have heard of an rb30 twin cam but still looks like an 30. Can u explain how this is different. Pretty interesting

the whole head and rocker cover is different. even to look at: http://www.skylinesaustralia.com/forums/uploads/monthly_10_2011/post-88683-0-39415800-1319598653.jpg

would love to see this thing with a set of itb's and open velocity stacks!!

its very simple. a TWIN cam has 2 cams....

I Made up a ITB kit off RB26 but the tuner said for a track car it would go out of tune, and they are a bitch to keep running perfectly pretty much. ITB are more for show on these than reliability in track conditions

itll only go out of tune if theyre poorly linked together, theyre much less complicated compared to say triple weber carbs seeing as theyre just a butterfly, maybe a couple vaccum ports, and something to link each set together. if each butterfly stop is set the same, and opens the same amount, theres not much that can go wrong. he probably just didnt want to tune it. theyre a bit more work to tune, have to use map or tps, and you'll lose some low rpm drivability without an IAC setup.

wheres it make its power? got a dyno sheet?

the top of the engine looks NOTHING like a single cam RB30, and alot like twin cam RB20/RB25.

Ps, love the twin throttle-body set up you have done to it. reminds me of a real Walky, LOL

Itb's would make a massive difference and are not just for show on a track car!!
