R32 Gtr - Oil Pump Collar

Duncan by the time you come in for an engine change the race will be over. What you need is 3 gtr's so when you break 1 you just slide into the next car and keep going...

Ivan Tighe Engineering in Wacol stock the crank collars. $90 each made from high tensile chrome-moly. You need to get the nose of the crank ground down and shrink fit the collar on.

Do NOT use grub screws to lock it in place- all you are doing is removing the interference fit. The only thing needed to hold the sleeve in place is the crank being 0.05mm larger in diameter than the hole inside the collar. The interference fit is a highly under-rated way of transmitting force which people stuff up due to bad machining/surface finish.
