i am wanting to know if someone can tell me what i should go with im wanting to run forged pistons and rods and i don't know what ratio pistons i need because im running boost.can someone please help me the pistons i need have to be bored over 20 i just dont know what to look for.....im running a h23a1 with a h22 head if that helps

 

Has the block been sleeved? What type of fuel and power are you aiming for?

 

You have to sleeve the block if you want to run forged pistons. There's a GREAT turbo prelude thread in the FAQ link stickied at the top of the fourm. Also most pistons won't be in a .020" over bore, they're usually listed in millimeters since that's what the block was designed in. Example, 88.5mm pistons would be 1step oversize.

Search is your friend...... 9:1 is a good compression ratio. I run mine a little higher, but as long as you're not over 10:1 and you've got a good tuner and fuel management system you're good. Plan on spending the majority of your money on your fuel system and tuning. If you don't have the coin, WAIT till you do. You can thank me later when you dont blow it up. Anything you've thought of, we've all done 100 times over.... read the threads, listen to the people that have been around.

 

so what size injectors would you recomend

 

That is based on the expected power output and type of fuel used. If you search on here, or google, you will find charts allowing you to determine how much injector you need.

 

I always tell everyone to buy Injector Dynamics 1000cc injectors. You will never buy another injector again. They're great injectors for 300hp all the way up to over 800hp. If you keep upgrading your goals, injectors need upgraded too, may as well get ones that work across a wide range and save the money.

Again, plan on spending the majority of your money on your fuel system and tuning.

Any good tuner would recommend you do the same thing.

Do a little more research before you bite off more than you can chew. You'll spend around 7-10k by the time you have a properly built motor, fuel system, turbo system, driveline and tuning. Depending on if you buy parts new or used, or have friends in the industry etc.
