Block of b18

[VT3C]

type R or b16 is PR3

but there must be SOME stamping to diferentiate between Type R and B16 heads.. yes they're the same head, but one has had mild port n polish and not to mention cams and valvetrain upgrades..

Ahh but the Japs are sneaky. Just the same as there engines. All there B16a's are stamped b16a, all B18C's are B18C. None of thie C2, C5 or C7 just JDM efficiency.

Smartypants not talking about BLOCK stampings.. talking about HEAD stampings.. the bit that says B16A/B18C.D16Y8 is the BLOCK yo !!

I know that.

Im just saying they could use the same head stampings on both HEADS. Because they use the same block stampings on both BLOCKS. ie VTi-R and Type R blocks are called C2 and C7 but in JDM land they are Both plain old C's. Could use the same method when stamping both B16a and Type R B18 Heads.

Actually it says on the FRONT of the block (exhaust side) "PR3/4"

however I'm pretty sure it is also stamped with something else on the intake side.. I vaguely recall it saying P30 either on the underside of the IM or the Block under the IM.. but not sure

hmm so it would be hard to tell the jdm b18c is from a sir or a type r then?
coz i found one for sale and not sure if its a sir or type r
