Thanks for that. Will search for BTR4 speed kits. Dont think I have seen any yet. But have since found out that someone does a kit for the nissan 5spd (still want auto though), but should fit the Nissan 4spd auto also. As for the RB30DET motor, it has been done before. Using a RB30 GQ gearbox (same as 300zx). But not really wanting a smaller motor. Have been in 4.2turbo utes and like the way this size motor works. So belive the 4lt BA XR6T would be perfect. Good torque, reliable good HP. Was going to go for 300rwkw. But think 220-250rwkw, will spin the wheels fast enough. There is a guy from melb also looking at putting one into a 99 GU wagon (current shape patrol).
