im currently working on my 95 gsr.
i have a stock b16a2 block
and im using a b18c1 head.
the stock compression ratio of the b16a2 block is 10.4.1
i know that using a gsr head will give me a little more compression
you know what compression is going to be with this set up.
i believe between 10.6-10.8
not sure

 

do a search for "compression calculator", this site is AWESOME!

 

c-speedracing.com they have the compression calculator there works good.

 

http://www.zealautowerks.com is better.

 

nope. the b16a2 block is 10.1 comp and a gsr head wont raise it at all. if u put a b16 head on a gsr block then it will raise it.

Actually, the p72 (GSR) head has smaller combustion chambers than the PR3 (b16a) head and will thus RAISE the compression.

 

man you dont know what you r talking about.
gsr head will raise my cr
the b16a block stock comression is 10.2
with the gsr head it will be 10.4

If all your doing is putting a B18C1 head on a B16A2 (USDM) shortblock. Then yes, you will have 10.44:1 compression.

But why do you have a B16 motor in a GSR?????

 

no crap why does a teggy have a B16?? sell that peice (the b16 block) and find a gsr or ls block... then have even more powa!! but like they SAID i dont know why people thing b16 have more compression... i remember the days when people put b16 heads on gsr and thought it would be so much faster LOL... good times

 

first of all the car is an 95 gsr 4 door.
heavy as hell.
i took the block and i installed on my 00 si.
now im using the b16a2 block in the integra and im going to be using the gsr head because the car is an obd1.

that was dumb

 

went from a 1.8 liter to a 1.6 liter...good job..hope you like the mad torque your going to get! lol.

 

i guess you just wanted to make your si faster right??? well you should just see if you can sell the b16 block or even trade on a b18.. or better b20
