I am reassembling the engine of my ‘92 GTO VR4. I have found evidence that the engine in this car is from a 1993 onward car, because:
-It has the later model oil pump
-It has the four bolt engine
-It has the forged crank shaft
I need an oil pump because the clearances on the current one are outside the limits listed in the manuals, and the relief valve was severely scored and seized. I am looking online for a new pump, and have come across huge price differences. Evil Empire Performance charges 360 pounds for an oil pump, but I have found ones on eBay for 70 dollars. (New, and the same model as far as I can tell)
Can someone give me some advice?
