    looking for roughly 6-8lbs boost, without changing pistons and rings or cams, wanna spend that later with b16 head.

    Why don't you just wait until you are ready to do the vtec conversion to boost it?

    Stock sleeves on the B20 suck.

    you will be lucky to get 5 psi out of that block, for more than 10 passes like george said the b20 sleeves suck

    Based on the research I have done, the stock sleeves on a B20 will only hold about 4-6psi from a T4 60 trim turbo with a modest tune. Granted, these numbers can be used loosely as you see fit, but if you plan to make any kind of power out of that motor, at the very least you need to resleeve it.

    :disgust1:

    if you replace the rods, rod bolts, and pistons and its tuned well they can take some boost. there are plenty of people making 300hp on stock sleeve b20s. i know of one that makes over 400whp with stock sleeves, and for 6 months and counting.

    you guys keep talking about the sleeves....
    from all the research i have done and from what ive personally seen, the weak link is the rod bolts. the stock sleeves are prone to getting hot becuase they are thin, but if the engine is tuned well they can handle a bit of pressure.

    this subject interests me a lot because i am currently planning a build of my b20z bottom end :D

    How many times must I say this? PSI is completely irrelevant UNTIL you select a turbo size. I wish everyone on this board would understand that. It'd solve a lot of problems more quickly.

    To the OP: Stock B20 internals would make me nervous above 200whp especially if it is a DD. Build it right, or don't do it at all.

    that was just my point.v dont really have a need for more than 200hp, damn speed cameras get you if your 10mph over posted, gets exspensive having a lead foot.

    You should be alright on stock internals then. Has the bottom end ever been opened up?
