this has prob been covered before but i searched a little bit and cant find anything

i have a B18C1 block
with a B16A head

do i use a b16 headgasket and a gsr timing belt?

i am currently trying to put on a b16 timing belt and it seems too tight to fit

03EM2guy

and the B18C1 block has been bored .20 over so i believe that is now 81.5mm

so with the B16A head still stock ..would the headgasket be different? what headgasket?

civic timing belt: 14400-P2T-004 BELT, TIMING (124RU26 D-130)
gsr timing belt: 14400-P72-014 BELT, TIMING (126RU26)
im assuming that the 124 and 126 is the number of teeth

since the single cam shows BELT, TIMING (104RU24 GB-333) which would be 104 teeth.

makes sense?


head gasket


honda civic: 12251-P30-014 GASKET, CYLINDER HEAD (NIPPON LEAKLESS)
GSR : 12251-P30-014 GASKET, CYLINDER HEAD (NIPPON LEAKLESS)


seems to be same.

i used a 99 civic si and 99 gsr hatch for reference



the stock headgasket is overbored. when i measured mine it red 81.6 so that was enough for the overbore

thanks man good info!

this should be in the faq

ok i got another ?

my b16 head/cams ..completely stock

the intake cam cap on the cam gear end where there are 2 12mm bolts and 2 10mm bolts
well the 10mm bolt on the side closer to the other cam is broke off at the bottom

how soon do i need to get this fixed? like before i crank it? or like just before i run it hard....?

id assume sooner the better, its not there for decoration...

generally speaking, if that bolt is broken, you'll be more prone to oil leaks there. So many people improperly torque those bolts too, 12mm = 20ft lbs, 10mm = 86 inch pounds...big difference.

lol im guilty of that as well. thank god i didnt break any of them.

i didnt know untill i got a torque wrench to find out how much is 7.2lbf and its not very much at all

I'm doing a poorman type r motor as well. I'm getting ready to send it to the machine shop to get bored/honed/hot tanked etc... but I was told that since im running the gsr block that i need to use the gsr timing belt. Since it's using the gsr oil/water pump and all b series cam gears are the same number of teeth, so the gsr timing belt must be using because the b16 is slightly too small

yes gsr/itr belt. the b18/b20s have a taller deck. (b16b is included in that too)
