Valvetrain for Rb25det

[BlockHead]

Does anyone have any suggestions on valvetrain upgrades for the RB25DET, I was looking at like tomei cams, but I dont know what would be a good choice cuz we dont have the rb25det here in the states. The duration I want on cams is 264 intake and 272 exhaust. Any suggestions or advice would be appreciated.

Well I didnt even know it had VVT till yesterday. Is it recommended to keep VVT or get rid of it?

Hi Guys, we used the 256 Tomei Poncams in an R34 GTT RB25DET, they work brilliantly, made 250 rwkw with its turbo hi flowed by GCG. Around 25 rwkw increase in the mid range and 15 rwkw increase in max power over the standard cams. They even increased the off boost power. It's a really nice multi purpose set up, road, circuit and drag.

Hope that helps

Are they 256 PROCAMS for both inlet and exhaust?
