right, first things first, i have a nismo n1 oil pump and due to the block being from a old r32 a new crank collar has to be fitted, the old collar does not fit deep enough into the pump, and after alot of research, it would be better to fit one, because i have read up on the pump failing after a short period of time! i am waiting to get my hands on a new collar at the moment, so this will have to wait! i will also get it crack tested and balanced with a tripple plate clutch! i cleaned the block with thinners and sprayed it silver,( i like things to look new)! i will change the rod and main bearings to acl since the cranks is out, and have also bee advised by someone (cal) to change the rod bolts to arp as well! also the pistons and rods will be balenced!

the head! the head has been pressure tested to start with and results were ok, i have ported the head using the standard abrasives deluxe kit which is really handy around the valve guides due to the small area you have to work with, i have marked out the area with gaskets for material to be removed, i have made the centre parts into knife edges on both exhaust and intake side, the exhaust side was finished to a mirror finish and the intake side to a 80grit finish, next is to get bronze valve guides fitted, i understand that the valve seats need to be cut to make them fit exactly due to new guides, i have asked for 3 angle valve seats to be cut because i can gain more power by changing the seats,new valve seals were also purchased!

porting and polishing makes a huge difference. just had it done myself.
what turbo set up are you running to achieve the magic 600hp?
