head cc of each below :
B16a/b B18C-R 42.70
B18B 45.00
B18C1 (SiR-GSR) 41.60

as you can see its bad idea to put a typeR/B16a head on a B18c non type R cause you will drop the compression ,unless of course you want to go turbo

about the gearbox ratio check them www.nofear.cu.cc (Honda Bseries info)

Hi guys!
I need to know if there is any specific difference between honda civic reborn 2007/2008/2009/2010 and 2011 models? also I have heard some rumours about civic reborn that its engine seizes in water? even if water is not too much? some ppl still say that civic 2005 is the best car and better than reborn ..

Thanks mate. Now it will be much easier to compare :blinx: i will want to lower my 9 without destrot the ballance. Not sure if apply skunk2 progressive ( 6 kg F an R) or Eibach. Spoon lowers not so much.

not to sound like a pick sod, but

"In order to increase the power output by 15 hp, and the max RPM by 200RPM, the engine goes through many upgrades."

Well as far as i know the B16A(2) found in the SiR/SiRII's redlines at 8.2K where as the 6B tops at 8.6K - isnt that 400rpm ?

Picky i know ;)
they never had shitty b16a2 in japan so there comparing it against the b16a
