Re: $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$

b18c1 usdm gsr and jdm sir-g b18c5 jdm type-R and usdm type_R......

not exactly, JDM motors are not stamped w/ a head code so yes a JDM ITR motor will only read, B18C but so will the JDM teg SiR-G which like eg86b16a2 said is a GS-R in america

you will probably be fine but when you get your engine, if you suspect that you may have a recieved another engine like a B18c1 w/ a ITR intake exhaust and red valve cover, you can always check the tops of the pistons should read P73-00 where the GS-R(SiR-G) would read P27-00 and USDM pistons are the same except they have lower comp and read -A0 instead of -00

My engine is Jspec ITR rebuilt by JUN Japan and it says B18C.....need proof just give me your email address and I can snap a pic and email it yo you.

nobody is saying otherwise...

Re: Re: B18C and B18C5? Type R motor

the jdm b18c1 has 180 hp, and is not a type r motor. All ITR motors are b18c5's, and differ with hp between usdm and jdm.

yeah but like we said, no head code stamp on JDM engines so it just says B18 on both
