Can you try to be more clear on what you want. And 400hp doing what? Justsleeving will not get you there what is your total plan

 

i am getting the head ported polished i want to put about 20 bl boost new intake new clutch under drive gears and mabe a little nitro and a few small things what ever i need to get the 400whp i can find everything i need except pistons and rod ot go with my sleeved pistons i am not getting it bored so it will have to bee smaller pistins
is there any place i can get them or get them custom made

Your totally lost 20 lbs of boost you mean. And a new intake? I sure hope your talking about intake manifold. You do not sleeve pistons. You have the block sleeved. Do months no years of research before purchasing anything

 

i know that you sleeve the block cylinders i am wanting 8-1 or 8-1/2 compression ratio just trying to find pistons and rods the right size from not boring block

I can tell already you have no idea what is involved and your getting in over your head. If your sleeving the block then it should not be an issue to bore it at the machine shop. Have them get the pistons you need. Also 8:1 even 8.5:1 is to low espically for only trying to reach 400hp. Again you need to do years of research, then once you think you have it down search another year after that then repost. See you in 10years

 

400whp out of a B20A5?

even if you knew what you were talking about, good luck!
