hi new to site but not to hondas.
what do you think i should do. boost my d or swap.i want a d.d but don't know much about swaps or turbos. i know that d series are great for boost.
my ride: 97 civic ex
my mods: 02 si wheels, 99-00 si stanley tails, ctr headlights, i/h/e, catback,high flow cat. new cap& rotor.here is a couple of pics.

 

I'd wait until I could afford a K-series K24(from a TSX) or K20a2 or K20z1 (from a RSX). Otherwise I research research research research. Then talk to a lot of honda lovers and the Mechanically inclined. Ask what they did and what they wish they hadn't done to there cars.

What do you want to do with your civic? Example of set ups: quick daily driver, Circuit racer, Drag racer, show car, or noise violater.

 

Boost the D. There are plenty of guys making a lot of power on D series motors. A set of Vitara pistons and tuner toys rods make for a cheap built motor that could handle 350 whp reliably. If you just want a low boost setup, a small snail will wake that engine up tremendously. Check out some of the setups here, on honda-tech, hmt, etc. This guy has a good build going. He is the guy to ask about this kind of thing.
