Tomei Poncams Cams

[tiels32]

I'm looking at buying some 256 tomei cams for my series 1 rb25det. I've found some for $909 delivered. Is this a good price? Anyone know of anywhere cheaper? Can u buy them over the counter anywhere in Adelaide?

On a second note my engine builder said i should try 256 inlet cam with a the next size up exhaust cam say like a 264. I gonna be running a 2540 turbo so i not aiming for huge power but apparently running slightly bigger exhaust cam helps earlier spool up. I believe to if i go bigger than the 256 cams i would have to fit heavier valve springs, is this true?

I appreciate any input

It would be cheaper to buy a better matched and more modern turbo than the 2540 that to install cams. You will probably save money, get better drivability and make more usuable power.

^ Agreed. 2540 is not the best choice, certainly better out there. A 2530 would be a better choice, and you certainly won't need to change cams for that

anyone else wanna confirm smaller intake larger exhaust cams will help with spool up down low - mid

yeah i've been thinking about the 2540. I've got it on my rb20 atm. 220rwkw but i'm definetely sick of the lag. Love the way it comes on but only happens at about 4100rpm. Upgrading to rb25 shortly so cheap options just to bolt on the 2540 and i'm half curious to see just how it goes on 25. But i have thought of getting a 3071 or 3076. Would a 3071 be more responsive than the 2540? I didn't realise 2540's had such a bad name for themselves before i got it.

A 2530 will make the same power but with better response - hence the 2540 is not the best choice really.

They are just a mismatched turbo

A member here who was in adelaide at the time (is now in WA?) steve, had an rb25 running the 256/264 setup with a 3037s. Search here there is a massive thread on the power he made (321 rwkw?) and how responsive i think it was.
