I’m about to do a b20 into my 90 gs and was just wondering a few things. This car will be my daily driver, non-vtec, with simple I\h\e, maybe an IM later. That’s as far as I want to go with it. Now, I know that there are different compression ratios, and I will get the high comp engine. What I"m wondering is if there is a significant difference between the p8r heads and the more common heads for what I want to do? Basically, I’m not sure if the engine i’m getting has the p8r on it, so should I still go ahead with the swap or keep looking.
the p8r head flows better from what I understand, they are also very hard to come across and only came on select JDM b20’s. Im sure someone will correct me if im wrong.
