Cams For Rb20

[RB ONEVIA]

ok so im in the market for some cams for my RB20 can anyone recomend any? im chasing around 250rwkws. car will have 040, 600cc, E8, 3071, 3" turbo back and 3" highflowcat and fmic. what lift and durations and lifts should i be looking at? i was looking at 264 with 11mm??

Holy jebus!

Let's pick a random number out of the sky on that one lol. Who does a 264 x 11mm lift?

Put a set of pon cams in it. I made 260rwkw with them and they were great in the midrange

Pon cams = 256 x 8.5mm lift

[RB ONEVIA]

i was told to go 256 or 264 with maximum lift so with 264 around 11mm lift. i dont know thats why i was asking. so far the closest i found were 264 10.25mm.

That sort of lift cams may beed to relieve the head for clearance. They also sound like Procams which means you need new valves springs and solid lifters....so thats a lot of money for a head.

3lit3 32 ... any credible before / after dyno runs with the cams on teh same dyno / tuner?

Thats alotta lift......I was looking around 9mm lift 264 duration myself in HKS......hunting 300rwkw

the tomei 260/8.9mm cams have worked a treat against my 20 w/ a gt30r on the side.

Got a dyno sheet??? would be good to see how they effect the power/torque curve and where boost comes in at

Dyno was a dynamics at a place called Dyno Source but they have closed now. Dr Drift was the tuner and we did the car over a 5 or 6 episode. Replacing parts as they ran out of room to make power. It was an experiment to see the max hp from each item. 233rwkw before cams, 260 after cams and 1psi less boost plus 2 deg less timing. I didn't get a print out of the last 260 run because the guy that owns dyno source kicked us out coz his wife just went into labour. Dr Drift is a member on here so you can ask him if you need credible evidence.

[Dr_Drift]

What he said is true..

Credible - That's incredible

So you needed two degrees less timing with larger duration camshafts??? Did you advance the crap out of it or something?
