Hi, We make a conversion to turn the original VCT cam gears into adjustable ones. They enable customers to retrofit a BA engine into another vehicle without having to use the OE ECU - all you need is a AU cable throttle body , an aftermarket ECU and you are golden. Sprocket conversion kit is $450.00/pr. Cheers, Brad Atomic PS: We can make any camshaft you desire however the cost is prohibitive. Please call me personally if you wish to discuss in further detail - 02 9705 0998
