ok on the refferance page this is what it states "AE86's "reserve pressure" oil cooler block should be removed as it's pressure retention spring can drop the oil pressure. Use and aftermarket "positive feed" oil block and larger aftermarket oil cooler for best results. VVT thrives on the high oil pressure to move quickly in and out of position so never do anything to drop the pressure in the 20V."
so my question is can i use the factory gts oil cooler with an aftermarket sandwich plate?????
