Hey guys. Im in the process of finding a set of tomei PROCAMS.
My mechanic and I have been talking at length about choosing the correct sized cam for my application, and Im sure he is probably reading this too
We have narrowed it down to the 260 range. I have been advised to go 260-9.25mm lift. The reason for this, while my engine was being built we had another engine being built to basically the same specs as mine, however this one had 270-10.25mm cams. This engine had suffered valve spring issues (springs unable to cope with the lift- thats all i can recall), and recently after its final tune it broke one of its springs. Luckily no major damage was done to the engine. So if i play it safe and go the 9.25's we shouldn't run into this problem.
So, my question; Can i safely run the 260 10.25mm lift cams? Can anyone vouch for the tomei type B 10.25mm springs as being bulletproof?
Or Should I just make it easy for myself, play it safe and go the 9.25mm lift cams to give me a safety margin?
Engine is powered by a gt3582, and I don't have a specific ''Purpose'' for the car, its not a dedicated drift bitch, track whore etc. The head is going solid, ported etc etc.
Would like to make 550rwhp, anything more would be a bonus, but I doubt the turbo will make it further than that.
