Yeah, show me a similar setup using a stock type r head with stock itr cams that makes 50-100whp more than this and a better powerband

Or just get real cams

no i would rather get the head that can flow the air that real cams would need. plus revving past 7k on an ls is always a crap shoot even on a built head, its not meant to be revved high just by the design.

Jcushing

care to show me one ounce of proof?

i take my p75 head over 7k every day...

look im the first one to point out the disadvantages if non vtec motors but i just get sick of people spouting off bullshit that they are basically making up. if you want to rev a non vtec head to 10k you can it just needs some mechanical work to be done. not many people rev that high though on the street and in street form they work just fine to 8k. they have the same port shape as a b16 head and can be ported to flow ALOT better than stock. they can also accept oversized intake valves even up to 33mm. ---- my b20 non vtec head im putting on in a couple weeks has 33mm intake valves stock.

people dont mess with non-vtec cause its just easier to bolt on a BETTER vtec head on but it doesnt mean you cant use non vtec.

Exactly.

Eh, it seems to be that it's more of a OMFG VTAAAKKKK hype. I'm not saying a vtec head is bad, it will be better than an ls head no matter what. I'm just saying that people shouldn't think the LS head is ----, since people can make just as much power on it.

beerbongskickass

Stock for stock there is no comparison... Vtec head > LS head. To get an LS head working as well as a vtec head you will have to drop a bunch of money into it. It's just easiser to bolt the vtec head on. For most of us that is all you need. Look at the people here at HMT that have dynoed there LS motors, ---- I made more power than they did. Drop a vtec head on and you got a good 50whp more right out of the box.

USS

Yup, I'm agreeing with you.

Stock for stock, vtec is better. There's no question about that. If you're going all out and building it, I would say go LS, port it, big cams and be different.

LS, love the torque, and with some ecent cams you should be doing pretty good.

what makes me laugh is people like you. Have you tooke the time to look @ a LS head? Have you seen how the rocker system works? LS's use floating rockers, there is really nothing securing them to the head. if you take off the cams they just fall out. Not only that they are prone to breaking.I work on a 11 second LS crx everyweekend, we are tired of the rockers breaking from revving it to 7.5k so we are sending them out to be cryo treated. Bottom line the head is not designed to rev high, should you could spin it high but like i said its a crap shoot.
