I'm gonna be buying a b16 in a month or so and just doing some research on it at the moment. I found a pretty good deal at hmotorsonline and have been looking at what kinds of things I would like to do with it. I found a head package from gude that basically has the head ported and polished upgraded valve train new cams and throttle body for $1500 and is supposed to be around a 55hp gain. Now the question I have is could I do something like this to this motor without doing anything to the low end? It isnt a rebuilt motor its just supposed to be low milage. I'm a little hesitant to go all out because this is just gonna be for street mainly maybe play around during the summer with some weekend racing. The main reason im hesitant to do the low end is from what i've been reading I will have to balance the motor which sounds pretty expensive. If I could get away with just a mild upgrade like type r pistons or something of that nature I would do it as long as I didn't have to pay out the ass for machine work. Any advice would be much appreciated.
