I replaced my stock RB25DET cams to a set of 260 degree/10.25 lift Tomei Procams and Tomei Cam pulleys.
My car got worst and even with dyno and road tuning im very disappointed with the upcome of the cams.
A few tuners were scratching heads on this particular set of cams. The power is okay from first few ks RPM.
It flattens out after 4200rpm @ 270whp and kept a straight power curve line after that.
One of the tuner said, my VTC is giving the problem and i got the VTC replaced. Later on, they were saying my
spark plugs and i got it replaced too. Till now no one is able to to figure out why and i replaced back my old cams.
After figuring out why... Im giving another try on the cams. I special order the Tomei Valve Springs (10.25mm)
and a set of Tomei Solid Lifters. I'll see whats the upcome after those parts are being installed. Kinda regretted
getting the cams but im not giving up.
Just wondering has anyone tried Procams or is it just mine that is giving problems? Need some input here.
Anyway im running a HKS GT2540, PFC, Walbro 255, Sard 550cc, Nismo reg and internals are dead stock!
Thanks!
