How to tell

[dciisir]

Hi All,

I am just wondering if there is a way to tell whether an engine is a JDM ITR engine or just a JDM GSR engine ? Let's assume the obvious has been changed. Things like valve cover, intake manifold and headers. I searched ebay and found that all the JDM B series engines have a starting number of B18C regardless of whether it was from an ITR or GSR.

arent they both p72 aswell?

The block stamping will only have B18C for the JDM engine.

If it comes with a PR3 head =Type R
If it comes with a P72 head = SiRG

The number right after it will determine what country its for/ from, ex:

B18C1 (GSR) / B18C5 (R)= USA

B18C2 (VTiR) / B18C7 (R)= AU

pr3 = top radiator hose is closer to the intake manifold side of engine.
p72 = top radiator hose is closer to exhaust manifold.
