Does anyone know the block code for a JDM Integra Type-R. Is it just a B18C or a B18C-R??? I know there is a JDM GS-R motor with the block code B18C so I thought that the Type-R would be different.

 

i believe it's just b18c.

 

Yup.

 

so what's the difference between the B18C and the B18C5 ??? thought both USDM and JDM blocks were the same on the Type-R's

 

i think they just code it so that u can identify which country they are for... otherwise they are the same thing

 

On the block it's stamped B18C in Japan. Officially it's known as the B18C XX(Insert either 96 or 98) Spec R. B18C5 is the USDM designate, B18C6 the UK and B18C7 the Australian. All of them have slight variations in power production I believe.
