Damn it, you newbies really need to do some research before you make stupid posts, like this one.

what you are talking about is called a frankenstein. there are different kinds of these the one you mentioned is a ls/vtec, as for companies that make vtec heads i dont know of any but i dont know half as much as some of the regulars on this forum but unfortunately they will only tell you that your stupid because you asked that question. to learn more just do a search or ask me ill help you all i can.

Well, I agree with the other members...please do some research before you post. Although, I am sitting here procrastinating from homework so I think I'll try to answer to the best of my current ability.

VTEC heads on a B18B = LS/VTEC (whoa, huh?). A B18B has 140hp/130tq. With a VTEC head, your LS/VTEC should have 175-195hp depending on the set up. I would reccomend the B16 head because of its cost and simply because it flows better..allows more air - CFM. The GSR head doesn't flow as well because it doesn't allow as much air as a B16 head does. The ITR head is the same as the B16 head, only it's mildly ported by Honda themselves. I hope you know that in order to do LS/VTEC, a head isn't gonna be it for you, not only will you need a VTEC head, you'll need to relocate the dowel pins, plug the oil supply hole which is included in an oil line kit that is specifically for LS/B20/VTEC conversions..[$75-125.]

As far as the question in regards to the companies making "the best" heads...maybe you're thinking about something like JUN..they don't "make" heads, they just do the machine work/install internals.

Hope that helps..it's comin from a girl so I may be a lil sketchy..lol

People say the B16 heads flow better than GSR heads but it isn't true.



From alaniz, building the fastest all motor hondas anywhere. The difference of a few CFM here and there can easily be atributed to casting differences.

Thanks for the information, Boosted, but hey at least I said the b16 head was a bit cheaper? Anyway, did you read the bottom..it's comin from a girl and I may be a lil sketchy Well, I didn't think it was that bad of a post. Thanks

also i would go with a b18a, bottom end, because it is open deck, and b18b is closed deck, just incase you want to turbo down the road!!!!!!!!!!!!

WFT...No Honda has a closed deck sherlock...and if the deck was closed...that would be better, it would create a stronger block around the cylinder chamber, so it wouldn't flex and crack under high boost...this is why you re-sleeve the deck, since the open deck honda desgin is weak....IF it had a close deck, it would be much more turbo friendly. BTW, the 92+ B18A1 is very similer to the B18B1, basically only 2 HP off. Now the 90-91 B18A1 isn't close. But no Honda has a "closed deck." I know plently of Nissan engines that come with boost have closed decks, but no hondas do. Even then, a closed deck is more turbo-friendly than an open deck, so what you said makes no sense on any level.

You're from Southern Oregon, right? I'm from Portland. Do you ever come to PDX?

And your post wasn't far off. I am not calling boosted331 a lier but as far as I have seen numbers wise, you were right. The B16A head flows 5.25% better. I see his chart shows different, but I have seen charts showing what that, so take what you will. I know me and several others have had this disscussion with him before about the flow of the heads. Either way, the B16A has a bigger combustion chamber over the GSR, 42.7cc to 41.6cc, which is one of the reasons it is the prefered head.

Hey good job, its so great to know that girls arent just getting paid by, looking pretty, im glad to hear that you , know TECH talk, the import casting scene is starving for import females, with beauty also, there is a show that comes on speed vision called, Import tuners, in a recent 5 sec. interview in louisiana, one of the casting guides, asked if their were any females around this place that had any knowlege of imports, sadly to say the answer was NO, I asked Y and he said, SON the import scene is starving for knowlegeable import tunetts, So keep up the good work, and keep acurate info in that lil head of yours, lots of peeps on this site know their stuff, this is a great site, to sharpen your pencil,,,, sorry for running off the subject!!!!!!!!!!!!

Look dippo..i have an LS too...A 97 B18B1 sitting in my car in the gargage...had it in there forever. I know the LS motor....NO HONDA MOTOR WAS A TRUELY CLOSED DECK........like you find the boosted Nissan's, etc. I don't give a shit what you think you saw...the B18B1 does not come from the factory with a closed deck....don't think so? Go start a thread and ask.

Also, a block guard really isn't worth much on a boosted app. It's a cheap fix, and really not a whole lot better. Lot's of engine builders call them worthless. You want to build up the short block? Re-sleeve it. Use AEBS or Darton Sleeves. They are a true wet-sleeve desgin, close off the top of the deck, but leave the water0jackets around the cyliders for cooling....and...they can handle upwards of 55psi....trust me...you wanna boost that LS much past 12psi (which you better know your shit to do, it's gotta be in prefect tune), then your gonna wanna change the rods, pistons..etc. You want high boost....re-sleeve. The LS does have a stronger block than other B-series motors, but it is not a "closed deck"...per say...sorry to burst your bubble.
