From all my research it would seam it will fit, I have noticed a difference and there is an overal hole in the bottom of the GTR pump just before the lip for the sump, on the GTS pump there is a smaller round hole just off center?

reason I ask is just fitted GTR pump to GTS and oil pressure is low at idle .5 bar and not as high as it should be at further RPMs ie 3000 rpm 3bar, should be 4bar, on old pump idle was 1bar/1.5bar?? any ideas people or we thinking the gasket has broke??

also am i correct in saying the back plate screws of oil pump should be 5NM tight with loctight?

regards
Rob

Well its all sorted, turned out to be the front oil seal and the oil pump gasket had moved during assembly, a point that may be of use is tha I used the oil seal off a Rover its made by FAI Auto Parts part number OS775, and fits perfectly
