B16 block with gsr head???

- Thu May 06, 2010 3:36 am #192048 Alright so here's what's goin on I have a jdm b16 block but no b16 head cuz I couldn't get ahold of one but I managed to get a gsr head... So I was wondering if it would be a good idea to put the gsr head on the b16 block... And also if I could use b16 cams on the gsr head???

- Thu May 06, 2010 12:33 pm #192112 it will work to bolt up, you prob wont see alot of power difference, the gsr head will raise your compression slightly, but it shouldnt hurt anything, id recomend getting a single stage intake manifold for your setup and you should be fine... however you would probally be better off with b16 cams to fit that engines power band charistics.... hope that helps :thumb:

- Thu May 06, 2010 2:44 pm #192129 yea b16 cams work fine, and the gsr head has a smaller combustion chamber, it will raise your compression, thats a fact :wink: it will probally put a jdm b16 at like 10.8to1 +/-

- Thu May 06, 2010 9:54 pm #192226 dude im like 99% sure that gsr heads have bigger combustion chambers and would lower compression on a b16. thats why motor builders put b16 heads on lsv and b20v for more compression.

my buddies b20v had a b16 head on it and the pistons smacked thge valves instantly when fired, so we put a gsr head on it and walllaaa it runs fine.

also i believe the gsr cams are an "upgrade" to b16 cams when they are installed in a b16 head.

like i said im 99.99% sure this is correct but i wanna hear what others have to say

- Fri May 07, 2010 12:52 pm #192348 well you sir are incorrect about the head thing, a b16 head is higher compression for a lsv or b20v because they come with a ls head from the factory not a gsr... and if you ever have had the 2 side by side the difference in the combustion chamber is obvious, the b16 has a more open and rounded chamber, making it the better head for a NA build because you can squeeze more of a dome on the piston up into the chamber, a gsr head has a flat, closed combustion chamber, making it the better head choice for a FI build... All i have ever really had has been a B series, and i know the parts pretty well...

(and if i didnt know this from experience or just general knowledge, go to any compression calculator and it will show the gsr head giving more compression)

LS 45.0cc
B16A 42.7cc
GSR 41.6cc <- smaller = more compressoin :thumb:

http://ariaspistons.com/products/acurahonda.html use this link, it gives compression specs for a LS & b20 with each type of head :wink:

and the gsr cams are bigger than the b16 from the factory, but they are ground for a 1.8L with a talller deck, more torque and a dual stage intake manifold, things a b16 was never ment to have, a gsr makes more torque than a b16 due to the stroke and rod length and the geometry in the bottom end... and the gsr cams were ground to match that bottom end and its dual stage intake runner, the lsa, and duration is off for what a b16 needs, as it is a higher reving lower torque engine, thats why i recomend keeping the cams matched to the bottom end rather than the head...

i will say i used gsr cams in my lsv with a b16 head, but it was only because i didnt have a single stage intake for my gsr head at the time, and i used the gsr cams because i wanted better low end, and a ls is alot more torque than a b16....

and for your freinds b20v the head could have been shaved, or if piston to valve clearence wasnt checked, and you said that engine was a high compression engine in another thread... so valve clearence is a must...

anywho i guess you learn somehting new everyday lol.
