20 Valve Camshafts

[DeftAnesthetik]

anyone know the specs on the stock camshafts that come with a 20v ST? going to be upgrading here right away but would like to know where i am starting to see where i will finish. also any recomended setups? i am running NA with stock ECU and want to keep it that way. seeing alot of guys running different profiles for intake and exhaust what is the advantage there? this question is probably on the board somewhere but using the seach function was no help to me today thanks in advance

Check club 4ag under camshaft specs. I believe they are there.

since the stock 20V motors are prety well set up from factory.. i hope you know what you are doing

its a bit different to a 16V where you whack on quads and bigger cams and a bit more compression.... the 20V has that already...

going pretty mild on this for a while, only want to change the cams and valve springs, i have no intention of cracking the head off the block until i have to... and when that happens it will be a total rebuild that will probably end up as a twincharged setup which of course will contain more aftermarket/custom parts that i care to think about right now. it looks like i can go as far as 264 duration w/9mm lift (intake side) and still keep the VVT and stock ecu, what should i pair this with for the exhaust? looking to keep the power band the same just move it up.

we have a selection of cams that are proven to work in these engines. sticking with the factory ECU is a real hassle however. most of our experience is with race versions using motec etc. email me if you want to buy a set or see us www.roadandtrack.net.au

Duration on the 20v is around 240-250degrees
lift about 7.3mm - 7.9mm

i would have to do some digging to get the exact numbers for you.
