Hi All,

I have a B18c1 OBD2 block and want to use a ITR/B16 head that's compatible.

I'm looking to purchase just the cast but need to know what to explicitly ask for PR3-x?

Or is there even a difference in OBD1 vs OBD2 PR3 heads?

Thanks!

 

doesn't matter head-wise. the difference is between intake manifolds. i would just stay away from obd-0 heads, being they're extremely old.

 

Thanks for the info! This is exactly what I needed.

 

But isn't a pr3 itr head slightly ported?

 

I will answer yes, but being I'm a super-noob it's from what i've read from others.

My question was specific to the OBD stuff. So I think he omitted all the non OBD related info.
