Hi all,
So at the moment i am currently building my first 25/30, really my first engine and i'm needing some advice.
i have gone with cp pistons, Manley rods, i will be running gtr n1 oil pump fitted with oil collar. with a cometic head gasket, all arp studs and acl king bearings.
compression is sitting low 8 cant remember exact 8.1. head is rb25det as well
so my question would be, what oil restrictors are people running?if any at all? needing to know this asap
and i'm also looking at changing valve springs and maybe cams, im wanting to keep the hydraulic lifters, unless someone can convince me otherwise.
what cams and valve springs should i run or could i just run standard cams and different valve springs with higher seat pressure?
overall looking to get anywhere from 500-650 hp
Thanks
