@Hockeyclark thank for your reply clark. yeah im a newbie here 🙂 my first post was an introducing myself post anyways. I actually do not like blowthrough carbs even with raising fuel pressure system carbs might act badly.and i believe efi needs crank sensor minimum. is there a cheap way for me to put a crank sensor in? fuel pressure water temp AFR are the easy ones my problem and concern is with crank and camshaft sensors. If i go preturbo carb i am thinking about putting the turbo as close to the head possible and put the carb directly on it.because exhaust and intake manifolds are in the same side runs will be VERY short. The unresponsiveness and lag freaks me out too that is the only reason i havent done it yet. will the close proximity between carb-turbo-head reduce the lag?
