2.6 Kenne Bell

I'll definitely be getting arp2000 bolts.

How about pistons?

Will be probably be aiming for manley, diamond, cp, or even eagle pistons. From my research I want stainless steel rings. For 600-650rwhp, what compression would I want on 93octane?

Most of the pistons made are pretty good imo. I prefer the ones made from 4032 alloy vs 2618. Mostly because it doesn't expand as much and allows for tighter clearances. My current motor has uncoated 2618 Diamonds and a ptb of .003". It's not noisy.

Probably the best buy out there for 4032 are Mahle. The are coated and have skirt coating, come with rings, and cost under $600 new. For 2618 pistons I think Wiseco is one of the better buys because they are skirt coated and come with rings. Manley also offers a good piston for the price.

I don't think Eagle makes pistons. I like higher compression. Some don't. With a stock stroke, stock bore you will max compression out at 11:1. I wouldn't go any lower than stock compression. I have in the past and lost hp when compared with the same blower on the stock motor and stock compression. Why stainless rings?

Read that stainless rings hold way better under boost than moly.

I have a 2.4 Kenne Bell and I make 436hp at around 7lb of boost.
