nissan which would have been 2500-2900$. so i figured up the cost of forged pistons 600$, h-beam forged rods (450$), and the machine work and came up w/about 2100$ including having my heads reworked. i just had to decide between all forged internals and lighter forged pistons for the quik rev, vs. new stock. wasnt a very hard decision. oh and the pistons are coated too :)
