thread showing the manifold for sale
http://www.nissansilvia.co.uk/vbb/sh...?t=4757&page=4 Gripos cam sale thread http://www.nissansilvia.co.uk/vbb/showthread.php?t=4730 sorry, your bearings wont help me with this rebuild. from memory the stock cam is something like 248deg, 8.8 lift and the Piper is 268 and 10.5mm or similar. the std cams so soft that almost as soon as the engine starts to make good power from the turbo, the cam starts to restrict with little lift and low duration. Your call, but personally without a decent cam the numbers might be there but the power wont be able to be exploited imho. I run the Autosprint cam currently, in fact mine was the first one that Geoff created using my engine spec as the basis. In real terms the Piper or Autosprint will give the improved performance in the range of boosted rpm.
