B18C Type-r or Gs-r?
 

With the block stamped B18C how can i figure out what year, or which exact engine i have? From what ive read B18C is either type r or gsr, is there any indicator that would distinguish my engine between the two, without doing a compression test?

B18C1 is gsr
B18C5 is usdm type r

yeah i've searched there, B18C is type-r and gs-r and they do not have further information to distinguish between them, thanks though.

Im talking about the B18C.

My engine has B18C5 stamped on it, so if it has B18C stamped on it, it's most likely not a type R engine

B18C means its a B-series 1.8 liter.
B18C is a JDM Type R
B18C1 is a USDM GSR motor
B18C5 is a USDM Type R motor

says B18C is the SiR, wikipedia says jdm type-r, and many other places list it as jdm type-r and jdm gs-r, so who is correct?

I'm gonna trust wiki.

All jdm gsr's and type r's are stamped with B18C. The one way to tell which engine you have is by the cylinder head or the trans. If the engine swap is complete and has not been put together from random parts. The intake manifolds are a quick way to tell or the groves on the intake cam shaft by the distributor. The trans if its an R trans it will be stamped on the front LSD unless it has been cleaned off. You can remove your axles to see if the dif is open aswell. Hope this helps!
