calling all ls/vtec and b20vtec turbo
I'm doing a research on ls and b20 turbo vtecs on which head is better for low, mid, and highend power. if all possible, please show your dyno numbers with motor setups. Please back up your arguements with facts your options are no use to me. let's keep it clean.

Re: calling all ls/vtec and b20vtec turbo (500hpsi)
IF you want real answers from people that would know. i suggest talking to the "head" guys around on this site
ED's racing heads and Headgames are 2 that i recomend
b18c gsr head is a better platform to start off with

i run a b16 head with gsr cams. and the gsr head isnt the beter head, thats why honda used the b16 head for type r's.

probley because the gsr all ready has welded combustion chambers so it is probley a little more solid to start with. but they do spend a grip on getting them built/ported. I would rather have a b16 head.

Re: calling all ls/vtec and b20vtec turbo (dumpeDc2)
they don't have a welded chamber already and if we were to think in those terms wouldn't the R head be better for turbo because of the lower compression?
The GSR head makes a lot more power in a turbo app. it has a better intake runner design and a real nice short turn radius compared to the R on the exhaust side, the injector is in a better location and there is room to make the combustion chamber shaped the way I want it. (MY OPINION)
Just because they put something on the Type R doesn't mean there is nothing better in a different application. The GSR head will **** all over a Type R head on a turbo car any day of the week....As it was already pointed out this is why all the people in Hot Rod class run this head!

can you explain more why you would rather want a b16 vs a b18? Show dyno to back up your argument if all possible.

can you back this statement? I have seen many turbo ls/vtech using b16's out run ls/vtec b18.

Re: calling all ls/vtec and b20vtec turbo (500hpsi)
yea I can back the statement up, I port heads for a living and the some of my customers are really fast. I wouldn't say something just to say it, nor do I have the time to look up old dyno sheets. Go to the races (NHRA OR NOPI) any Pro class turbo Honda will be running a GSR.
Monkey see monkey do if Gary Gardella runs one so should you.

So, a daily driven turbo ls/vtec consumer wanted a to know which is a better app. for the street and with some weekend races, what would you recommend. Wouldn't a b16 also raise a compression slightly vs. the b18?

no, the combustion chamber on the gsr head is smaller. the gsr head would raise it a bit.

Stock piston/rod B18A block
Stock vavletrain B16A2 head
15 psi
For a shitty comparison, when the head was on my stock piston/rod B16A2 block at 10 psi it made 251whp and 186 tq untuned. From talking to others with an LS/VTEC, most run a GS-R head. I'm pretty sure using a stock GS-R head will give a slightly higher comp. ratio with an LS block.

what head combo are you using? however, great numbers.

most of them are probably running the gsr head because most of them run gsr motors and because there is no need to swap it out when your going to spend $5,000 on head work anyway, but in the stock form the b16a head makes better power. and that's why gsr guys swap them out and make the poor mans type r (gsr bottom end w/ b16 head). And if you run a b16 head you can always get a used type r intake manifold for cheap and have way better efficiency than that shitty gsr manifold.
