Go b18b (2,000 to 3,000)with a turbo(2,500 to 3,000) 500 left for other stuff , better setup than b16a turbo, and stay away from Nitrous i had it on my car an it is really addicting and the bottle fills will cost you more in the end than buying a turbo kit right now.
My buddy has a 89 dx hatch with a stripped interior and a zc with a couple mods. Walks pretty much everything around here. He ran a 14.6 on borrowed drag radials at the strip. Car only weighs about 1500-1700 lbs but still street legal and a daily driver. Want pictures just ask me.
