Hey all sau'ers...
Im currently upgrading my r34gtt rb25det neo, with bolt on mods.
I will be using a hks 2835 pro s as well as all supporting mods.
Now ive spoken with my tuner and he recommend for tomei poncams thats i use 252 degree 9.15mm lift as i will prodominantly be driving on road (mind you its my weekender toy) and the odd track day a few times a year.
Ok well im NOT looking to fry my engine, so i dont want to be sitting off the rev limiter and high rpm's as ive been told will tend to fail a lot faster and in turn cause engine failure.
Although contradictory to all that, i want to be able to get a fat torque range throughout the mids and have minimal lag with the hks 2835 pro s but as well keep some power up top for when needed. (eg qaurter mile runs etc)
now my concern/enquiry is even though my tuner has recommended 252 9.15mm lift poncams i have also heard that 260 9.15mm poncams work a treat...now im not 100% certain which would be more beneficial to my application, as ive said above i am mainly wanting to minimise lag, keep the torque and maximise the mid range and not have to rev the hell out of the engine to only make power in the higher rpm's which in turn would cause more wear and tear and failure in the long run. (alot faster that is)
what is your opinion on all this?? (obviously from experiences)
from what ive read....sydneykid tends to have a great understand of cams and how they may/can benefit an engine so im hoping he may make an appearance to this thread.
any help would be much appreciated.
thanks, Bass.
