I'm in the US, New York to be exact. I'm an SCCA racer, we run a rear wheel drive tube frame Sentra powered by an A series engine and a tub framed 1200 of course this car also uses an A
series. Both of these cars compete in the SCCA GT5 class. Before we switched to the Nissans we ran a Civic 1200 that had an adjustable cam pully. Believe me a small change in cam timing can
result in good power gains as well as getting the power where you want it.

I'll try to get more info on the E series head swap. The guys that are doing this run in the sports racer class. They are formula cars with envolope type bodies. All of these engines are
dry sumped and use a belt driven oil pump. I don't know if they run a cam in the block or not, I also don't know how they get oil to the cam in the head, I don't remember any external lines
but I'll try to find out.

Let me know when you build the belt drive
