rb25 head

[kunifa]

i was just curuous as to how much it would cost in total to but an rb25 head on my n/a vl. How much would it cost to just buy the head roughly and how much would it cost to do it all???

Seen them around for about $900
Head, rocket cover, turbo, manifolds ect
not sure on the costs to put it on do a search on google and you will find heaps of info

There is allot of work involved because although it bolts on I don't think all the water jackets line up exactly but I could be wrong. You will need a custom made cam belt and the RB25 ecu to run the dohc head.

should be able to pick up the head with manifolds for about a grand. turbo or non turbo? the non turbo head will bolt on with no modifications at all. but u have to mount an extra stud in the front of the block to hold the second timing belt tentioner.

if u are looking at the turbo head their is an oil gallery in the face of the head that feeds the variable cam timing assembly. there is no corresponding oil feed from the block. so the hole must be welded up, faced and a fitting tapped into the gallery on the side of the head. then u gotta get a high pressure hose to go from any point in the main oil gallery in the block to the fitting in the head.

if u are keeen to do a turbo conversion your best bet is to buy a non turbo rb25 head and bolt the turbo manifols and turbo on. the oil and water lines for the 25 and 30 motors are the same.

make sure that your motor is a series 2 if u plan on doing a turbo conversion because the series one block does not have a threaded hole to screw in a fitting for the turbo oil return.
