cool. n1 pistons are cheap. about 80 each.
use sr20 bigend bearings from acl. (there identical,im not sure they have the 25/26 bearings on file) about 80 bucks for 16 shells.
use rb30 mains (acl) about 60 bucks (two sets,explained later)
the n1 piston uses better rings but is still prone to breaking. a friend told me a stock pistion can take about 3 seconds of detonation an n1 can take 4 hehe
use a 5 dollar oil restrictor (tomie)
use a genuin cambelt.(cheaper than aftermarket)
the gasket set is a bit pricy but un avoidable.
dont bother with a steel head gasket. (mines oem and pushing 450hp atw.)
one thing worth getting is a n1 harmonic balancer.
dont get arp studs. (unless your getting it line bored and torqueplate honed.)
use tomie rod bolts. (arp use the vg30 ones and there to short.)
set it up 2.5 thou on the mains and 1.6-1.8 thou on the bigends. use the groved block side maines on both sides of the crank. but you will have to get the girdle notched to suit the bearing retaining notch on the other side.
or you could not bother lol.
get the crank grub screwd so you can clean it properly.
