Well I already have the JDM d15b SOHC vtec-e int he car. I just dont know if i want to boost it or drop a b16 in. It honestly feels faster then my stock b18. My car has 4-1 header, intake, a non fart can muffler, sway bars, adjustable springs, lower and uper front poly control arms and rear lower poly control arms, yahanika motor mounts And i have been considering a edelbrock manifold. Does anyone else here have the d15b? you ever put it up against a B16? I hear lots of good and bad about BOTH motors lol I also have a zc tranny in my car. i dont want to switch to a b16 if its going to slow me down or be like the same
