9.15mm Camshafts

[tacker]

a quick question do you need to machine the head to run 9.15mm lift cams on a GTR?

no. direct fit and can use standard springs

Cheers, better start looking around then :-)

Or for around $260 get some Performance Springs from Performance Wholesale, handle up to 11mm of lift- very cheap, good quility, I have them in my RB25 and bought some for my 26/30buildup as well

Food for thought

you might need some shims and you ought to get some new cam bearing studs/bolts but, otherwise no clearance issues if you are reffering to the tomei ones.
