I've done quite a bit of reading about building the engines but I'm still lost. Basically my goal is to boost my JDM H22 motor 8-9 psi. I want to run it maybe like 6 daily. Basically, I need forged pistons, rings and darton sleeves(bore?). The pistons will lower the comp to 9 to 1. How much will I be looking at and if I can get a shopping list of parts, I will really appreciate it. Thanks.

forged pistons $500ish if you run shelfs - go with CP 9.0:1 pistons and wiseco rings

rods $300-600 (i recommend crower billets)

dartons $ 900ish sleeve and install

Then you will spend roughly another 500 on OEM parts such as new gaskets, seals, bearings, etc, etc.

There are a ton of other things I highly recommend such as larger injectors, custom turbo set-up, hondata, etc.

damn... I had no idea it would cost that much for an engine build. Thanks for the info.

if there arent too many miles on the motor you dont need any of that **** to run 8-9 psi and 6 psi daily. just get a good fuel system and a good tune on it.

That is true. I would not go over 8psi though, H series piston rings are very weak and prone to breaking under heavy load. Invest in a hondata, fine tune your motor, and you will be safe pushing 8psi all day long given that you do a cylinder leakdown test and yield good numbers.
