    Boosting H22A good or bad?

    I have been against boosting a VTEC motor in the first place, but then I got thinking: There has got to be a safe way to boost my H22A without tearing something up. I know I would have to get lower pistons to lower CR and all that jazz. I was also wondering if anyone has done it to theirs. I know the F series is a better choice in the realm of boosting. Very simliar to boosted D series vs NA B series. Any advice would be sweet. TIA

    IMHO, there is always a "safe" way to do something... but engines that were not designed to take the burdon of forced induction will not handle it without the slightest chance of f***ing something up.

    and... as we all know, boost is an addiction. you could probably run it at like .5 bar safely, but you'll want to try and push it up to .75 bar, 1 bar, etc etc till something blows... at least i know that i would... and probably end up with a really big paperweight

    of course if you threw enough money at it, you could run 1.5 bar, but then there's just more money to be thrown away SOULD something go wrong. (can you tell i've been contemplating boost myself lol)

      Its a tough choice really. I may just stick to N/A since that's what it was built for in the first place. There is a way to get some power out of it that way too...ah soooo many choices, blah....

          Whats vtec got anything to do with it? Vtec engines are better to boost for street cars over non vtec any day. non vtec cam lobes are huge all time(not stock bs), cause shit idle, shit gasmilage,Wont last as long. Vtec is great for boosted street driven cars. So what was the vtec part about? But other than that, I would not boost an H. just gonna cause probs, atleast my friend here has, he boosted the stock engine 130k miles or so, lasted 2-3months... rebuilt it all 100% stock, dont ask me why, ran low boost again around 7psi from a t3/t04e 57 trim, and broke again within 2months. F22 ftw. But im sure you can boost an h22 no problems...but ive yet to see it myself.

            edit- ^^^ VTEC motors have higher compression. And supposedly lower compression non-VTEC motors are safer for boost. Hence why everyone gets low compression forged pistons for high-boost

            From owning a turbo Integra right now, I have some good information lol.

            I've been boosting 5psi untuned for 4,000miles now, on a stock non-VTEC B18B1. It is an awesome feeling, but with an H22A, I honestly wouldn't turbo it. I've just bought a TypeS H22A for my Integra, and i'm planning on leaving it to basic bolt-ons.

            With the H22, it depends on how far you want to take your power to. If you want too much power, then you need to get forged pistons and everything, and isn't there something wack about the H22, and it doesn't like forged pistons without re-sleeving the block and some stuff. Something like that.

            But if all you want is less than 8psi, then it should be able to handle that boost.
