JDM motors only says b18C, USDM motors says b18C5.

correct.

[Chris N]

b18c = jdm gsr
b18c = jdm itr

b18c1 (gsr) and b18c5 (itr) are what they are called in the us.

you can't tell which is which with jdm itr and gsr without doing more homework. jdm gsr does NOT use the usdm gsr dual runner intake manifold i dont think, so that doesn't help clear things up either...

also on my jdm itr motor there is a green paint mark behind the distributor. From what i'm told this is where the engineers tagged the heads for ITR use.

Really? If true thats a cool little piece of info.

i think you will find the JDM SIR as its known is labled b18c4 where as the JDM ITR are labled up b18c

No sir, confirmed... Green paint by the dizzy.

PR3-x where X= 1-4.

Same head casting as the B16...

No BS there, Green paint- OE. Orange paint- OE replacement (sometimes)

no...


B18C4 is the engine code that came on the motors in the MB6 and MC2 Civic's in this country, the SiR's were B18C's too, the ITR motor was called the B18C Spec-R, but obviously that couldn't be written on the motor, so B18C it was....

i stand corrected and my mate has been ripped off, his SIR is a b18c4.........................i sence trouble
