he guys got 2 questions for you all regarding cams. I have a full built bottom end in my gtr with cp pistons, eagle rod's ect and all the other good gear and i have n1 turbos. Here is the thing the bloke that built the motor and the prevouse owner decided to leave the cams and head stock and it hasnt been retuned since the build. My question is What sort of power and responce can i expect from the stock cams at a maxium relieable power. With all other supporting mods like injectors fuel pump pfc ect. And what is invlove in fitting say 260 degree 9.15mm lift pon cams like do i have to replace the valve springs and replace the lifters or can i get away with springs and reshiming the lifters in it and will it be worth it to spend the extra coin to do this like will it improve responce on the street.
And question 2 how much power / flow can the stock dump pipes handle as the exhuast that is on the car currently is 2.5 inch front pipes high flow cat and 3 inch cat back. and once again will this make a huge differance with the n1 turbos or will they do untill both turbo's upgraded
cheers scottie
