cheers for the replys ,i was looking at the oil setup today and noted that the turbo oil pipe comes from the oil pressure sender on a t, ithe pipe is 5mm internal diameter ,i am going to change this to 3mm to see if this improves the tickover pressure of 11psi there should still be plenty of oil going to the turbo ,my last turbo ran quite happily on a 3mm pipe , as for the the high revs i will change the pickup pipe position when i change the oil this w/e and see how that goes , ihave been told that my car is pulling about 300bhp so it is a bit vicious on accelaration
cheers jon
