    Hi,


    I'm currently rebuilding my head to accept some skunk 2 stage 2 pro cams. I know these will work better with a higher compression so I'm wondering how much my head can be skimmed to raise it a bit?


    Thanks, Tom

    Ok mate may give them a bell.


    Where are they located?

    Id say it depends on what pistons you are using and what the piston-to-deck height will be.

    I had 5thou taken off.Don't take off too much or you'll have valves meeting pistons!

    to get the sort of compression that these cams will work best with you should really go with new pistons with a range of 11:1 cr on a b16. i have seen countless dyno sheets for these and they seem to work very well with the 1.8+l's but only produce good figures on 1.6's with great compression.

    The compression increase through skimming will be barely worth talking about.


    Remember that unless you fit larger valves, theres not much point in getting cams with a higher lift than an EK9 or DC2 cam. (As Valve head diameter x 0.25 = distance the valve should open to acheive max flow, anymore won't increase the flow any further).


    More aggressive quientening ramps fair do's

    Ok thanks for the advise everyone. I got the cams at a price I couldn't really refuse though so I may as well give them a go. I may swap them out for a set of ITR or something at a later date if I don't get on with them.
