Is This Motor a B18c-R ?
I recently purchased what was supposed to be a 96 Spec JDM B18C- R. I am positive the head is an ITR, but the back of the block is stamped p72 (1-1) and the engine code is B18C. After scrubbing the whole engine down so I could read all the codes I noticed that this block may be a JDM GsR. If someone could help me identify this I would appreciate it.

i do not want to believe that the seller (not announcing his name yet) scammed me, but we both need proof that this is or is not an ITR motor. If somebody can prove to me that this is an ITR motor I would appreciate it. If you do have a 96- 97 spec ITR motor please post your casting marks, especially on the back of the block next to where the transmission bolts to.

there is no way to tell without taking the motor apart...if it has an itr crank you can pull the oil pan to get a look at the crank....pr3 is just a b16 head...p3-X meaning there is pr3- 1-4 and 1 through 4 is just the casting number....the casting number does not mean it is or is not a type-r head. only way to tell if it is a type-r head is to look at the intake ports and see if they are rough or smooth about 2-3 inches up from the valve. normal b16 heads are rough casting from the valve all the back. of course this still isnt 100% accurate way to check.

complete bullshit, all itr motors are built on p72 blocks. if you are hell bent on finding out you have to either use a fiber scope in a spark plug hole to look for the dome or pull the head. that's likely a 96-97 itr engine. some of you lames who are posting have no clue what you're talking about and you know it !
you could also pull the valve cover and inspect the cams, look for the yellow and blue springs and see what you find.
also, early jdm itr engines had no port work. they were made as cast. late 96 and 97 were hand finished and 98+ were cnc

It should say p73 on the block no?
Never had a itr myself but all my LS were stamped pr-4(pr-4 pistons), b16 1st gens were stamped pr-3 (pr-3 pistons), b16 2nd gens were stamped p30(p30 pistons). etc etc.
If this applys to his block then he's looking at gsr slugs inside, but hey like I said I've never been lucky enough to own a R engine
I agree I fiber scope would clear up any confusion

all JDM Gsr/ITR engines are stamped p-72 (1-1) on the back. Steve at HMotors helped me identify it. The intake side of the head has a smooth polished finish along with the correct casting marks. You can tell the motor has never been internally modified. There is not one leak and all parts are OEM. I just got scared when I saw p-72 considering thats what my GsR engines casting says on the back. The guy I bought it from got it from H motors also and it is infact a 96-97 spec ITR

Aren't the blocks stamped with what piston is inside?
