thanks guys for the quick reply, lol to the stealing of the engine in the middle of the night, its interesting that u can actually swap the dohc engine of the ba to an au, like wouldnt that throw off everything, like the transmission will still only expect the (soz if im incorrect) 140 kw's of the au compared to the higher power of the ba, would u need to tune it and wipe the
ecu? also what about bonnet's, will a ba or eb bonnet fit onto an au1? and as soon as i get my au ill register, i got a mate with an eb and i could borrow his bonnet to get an au over the pits if it doesnt have a bonnet (at least untill i buy my own), thanks guys for your help Derek
