How can you tell if the motor is from a integra type r or integra siR ?

 

the intake manifold and or valve cover in most cases

 

both valve covers are red and the engine has b18C stamped on it, and owner claims it is a jdm integra type r motor, how would i know it is not a jdm integra sir motor? How else besides by the intake manifold, also how by the intake manifold?

Look at the head to see if it says P72 or PR3. If it still has the header heat shield, you might have to take it off because it gets in the way.

The ITR and GSR intake manifolds look very different from each other. Search for pictures.

 

ok i see the diff, thanks everyone!

 

I would think (before buying) a compression test would answer a few important things.

It would help the potential buyer determine the health of the motor, but it certainly won't be useful for differentiating between the relatively minor compression ratio differences of the two motors.

 

An SiR IM wont fit on an ITR head so if it has the stock SiR IM then it'll be an SiR motor and vice versa.

 

a gsr with skunk2 manifold would still get u fooled. look for the p72 stamp on the head
