I was at a local junk yard this morning and I found a b18b head in good condition, I was wondering if I could swap this in my b18a?? I dont expect any big power gains....but stuff to cosider is: The head has less milleage than my b18a, I can benefit from the intake cam and the intake manifold differences and somebody told me I can still run obd0...is this true?? or can I just convert it to obd1 with just the head swap and the right ecu?? Also I will try to install a 96 type r oil pump in the b18a, has anyone ran into any issues when doing these??

 

help guys

It will make very little to no difference. The b18b1 has slightly bigger intake ports but that is about it.

 

Instead of swapping the head and having to deal with a new head gasket and head studs, just buy a $160 Blox Type R replica manifold for your LS, and change cams to your head from the B1.

Don't expect huge gains, you probably won't even feel it.

The difference in oil pumps is a small washer that ups the oil pressure. After 1996, all LS/GS/RS/SE/GSR/ITR oil pumps are the same.



Notice part #12, the little washer. The 95 and older models had that for less oil pressure in the B18-non vtec motors. After 1996, ALL Integra models had the "Type R" (they're all the same) oil pumps.

Endyn sells modified oil pumps.. they're ported and shimmed.
