yeah it would be fun to take my SOHC engine and beat a DOHC engine. I was just wondering if anyone had done this...because the way that I see it is this. By the time I buy an H22a, it's going to be like $1500-2000 and for that much, I could buy/build a turbo setup for my F22. Plus then I would have to build up the internals of the H22 and buy a turbo setup for it. So, for about 1/2 the money it would take to build up the H22, I could build up my F22. Plus I'm on a tight budget so the F22 is a better option in that respect too.
