Does anyone know if there's any difference between USDM and JDM B18C1 cams? I bought a used set that I'm trying to sell, but eveyone keeps asking me if they're JDM. If there is a difference, is there anyway to tell which ones I have?

I did a quick search, but couldn't find anything other than the CTR intake, GSR exhaust cam combo.

Thanks in advace.

 

as far as ive seen there is only one make of GSR cam, USDM and JDM are the same.

 

Can anyone else confirm this?

 

I'm with notstock 93 on this one....

Although there were 2 versions of US B18C cams (94-95 & 96-01), but I dont think the cam profile changed between the 2 versions.

JDM B18C cams more than likely have the same cam profile as US B18C1 cams, but then again they might not...because the JDM B18C puts out 180ps which is mainly due to ecu programming, higher compression pistnos and possibly a change in cam profile. I don't know for sure on the cam profile tho. I'm sure if they are different its notthing to squabble and be **** about. If someone wants to make more power they should look into getting type-R or better cam, know what I'm sayin?

 

they are the same cam jdm and usa, a friend of mine has some jdm gsr cams and i compared them too the us cams and are the same
