Hi guys. Haven't posted yet but I have some questions as to the power limits of the drive train. I was originally just going to do a Twin Turbo swap and call it a day but got the bug for much more power. I am going to be building my N/A motor into a twin turbo motor (complete bottom end rebuild and so on) making around 500hp or more. I'd like to know what the trans, driveshaft, diff and rear axles are capable of holding in terms of power. I'd also like to know if it is recommended to upgrade the oil pump and pan and the rear diff mounts. Pic of my car for attention.
