hi there, i have a vl commodore with an rb30e, i only got it because nissan make great engines. anyways, i am very interested in a twin cam head conversion, as you have done. i have came across an rb25det head, can i use this, even though it is from a turbo? how much did your conversion cost, being the head, labour and gaskets etc, ? i am very keen to do this conversion, but i have a moderate budget. would i need a new computer and efi system? sorry about so many questions, i have been trying to contact someone about this for 6 months but to no avail..
your help is much appreciated,
luke l
