I am planning to purchase a Type R motor, but I don't want to get scammed. I have been doing my research, but unable to find anything related. How do I tell the difference between a JDM GS-R motor and a JDM Type R motor (besides the valve cover)? I know that the engine code should be B18C (top) and either starting with a 1 or a 2 (bottom). Thanks for the help

 

jdm type r motors come with different trannys, J4D for 96 spec and N3E for 98.
jdm gsr motors come with the S and Y series

 

the easiest way to spot a visual difference (so long as it hasn't been changed) is the intake manifold on the GSR. search it up and you can see how different it is compared to an ITR.

also, ITR heads should have a little bit of green paint just behind the distributor area (if it hasn't faded off)...

search for pics dood. there's tons on HT

*edit - i'm bored at work so here are pics for you since i used to have a JDM GSR

GSR - note the design of the intake manifold


ITR

ITR motors have PR3 stamped heads, GSR motors have P72 stamped heads
