Andrew, what does that L20 cam run like in your L20b with respect to
driveability and rev range?
As my L20b gets closer to turbo power one thing I have to consider is cam
specs. I am unsure whether to chuck in a C cam (or other factory cam) for
the time being or jump straight to a turbo grind cam. At the moment it has a
Datrally mild grind cam in it. Your grind sounds promising! What did it cost
to grind?
The L20b is just stock at the moment. Before the turbo it wouldn't really
rev too madly over 6000.
Would your grind be suitable? or have any recommendations?
thanks in advance!
zac
