B18

[panda[cRx]]

no i am almost 100% sure the JDM type r has just B18C printed, no number after it
no idea what u saw ?_?

panda, u are correct and it was stamped B18c

well i just had a look at my baby sittin in the garage (its been a while)
but yeah, mine is b18c1 with just b18c stamped.

i'm guessing it must be same deal with b18c1 (jap vtir)

[tanghy]

c1 is not jap vtir
c1 = american GSR

[OLM-02R]

b18c1 is USDM GSR engine...thats wat i got on mine...

[panda[cRx]]

hmmm then wtf is jap vtir? lolz
i honestly dont mind as not goin for high compression *wink-wink, nudge nudge*

[tanghy]

jap engines have no # after the C
if it is a SiR engine it will have dual intake manfiold
if it is a type R it will have a single intake

um, if that is a picture of your engine number - that is not a B18C1

it is a B18C

i really dont understand how you could think that that is a B18C1

[Civic Type R]

all JDM engines have no number after the C.
JDM VTiR = SiR and Type R are all B18C on the block. As Tangy said, the noticable difference in with the intake runners and the Type R has Spec R on the blue Vin tag.
O .. and the stock Type R has a red valve cover too.
