Hey guys,
Currently running a rb26/30 combo in a rwd r34 gtt. currently makes 308rwkw on 20psi with a gt35r/82 and OEM rb26 cams. my aim is to crack the 400kw mark.
Some have suggested my setup suffering from valvefloat and some have said i need bigger cams. Nengun have listed some Procam + Adj Pulleys however id like to know what cams will drop straight in, and what cams will need work to fit?
Also a few questions
- I understand Pro cams need new valve springs regardless of if they need it or not?
- And what are the differences between Pro-cams and Pon-cams.
Basically im not very informed when it comes to what makes a good cam choice, so any help much appreciated. the car is a 90% weekend street car with the occasional drag strip night.
cheers
