i have heard to many debates over this.what is the real difference between a b18a/b18b pump,b16 pump,b18c1 pump and the type r pump.i have heard high volume high oil pressure and such.whatis the actual flow numbers.how many extra pounds of pressure.homany more quarts per hour does it push.i tried a search and found nothing.interesting note though.the type r pump is stamped p72>wtf?

I cant tell you numbers, but I can tell you that ALL obd2 b series oil pumps are the same
meaning, "itr pumps" arent anything special

SCIVIC94

cool.anyone know if obd 1 and 2 are the same?any other opinions.

pdiggitydogg

vtec obd1 and 2 are the same (to my knowledge)
obd1 ls pumps flow less

SCIVIC94

ok that was my big thing.i have an obd1 ls.i was looking at typer pumps but cant justify paying typer money if it is not worth it.thanks

SCIVIC94

is obd2 ls different then the vtec?
