pistons and rods....
 

would you use in a 89mm h23vtec build? i plan to boost also.

Well, any of the big brands out there will work. It just really depends on what your goals are, power wise. It is highly recommended to use flat "dished" pistons on turbo applications to squeeze in more volume of air. Look into forged internal upgrades since they proven to be stronger than cast. These are my choices for brands, in order of my preference:

PISTONS:
-Wiseco (ceramic coated)
-CP
-Arias
-JE

RODS:
-Manley/Full-Race
-Pauter
-Crower
-Eagle H-beam

Bearings:
-ACL
-OEM

Head Studs:
-Golden Eagle
-AEBS
-ARP

Be advised that some companies only offer certain sizes on pistons. So, it may prevent you from picking the company that you really like. When it comes ordering pistons, talk to a representative instead of buying directly online. There are a few reason why. For one, not all turbo pistons are flat dished. Second, your crank stroke and rods must be taken into consideration to target the compression that you want. For example, I had to "mill" my head 20 thousandth just to achieve a 9.2:1 compression. When the current combination I have and NO head milling, I would've end up with a 8.1:1 (... or something really low) compression.

Goodluck. If you need more technical assistance, I would contact Earl from Honda-Tech. He is a superb guy to deal with and will work with you to achieve your goal at the same time, give you great deals! Or just let me know and I'll get you in touch with Terry (Boostfed) at Honda-Tech since Earl gets busy sometimes.

i want to achieve 500hp on boost. i would like to get 9.1 compression. but im looking at going 2.4L or 89mm bore. do they make pistons for the H that big?

yes. look into JE and CP. They have the widest variety.

im thinking crower rods and je pistons.

Not a bad combo. Get ready to shell out a lot of $$$ of this project bro. I dropped in almost $10K on mine and still not finish...

Make sure that you continously research. I'm not gonna lie, H-T has the most technical info that you can get. The Force Induction forum there is by far, the best I've ever seen. All the big name guys are there too.....
