I own a 1993 Honda Civic LX 4 Door. I have a D15B7 Engine in it, with an HP Racing 4-2-1 Header, No Name short-ram intake w/ K&N Filter, and APC 9.3mm Spark Plug wires.

I have always been a fan of SOHC Engines. I guess because every else wants a DOHC Vtec, and I have always wanted to build up a SOHC engine, but I dont really know how. Currently I have an estimated 115hp(I know its not alot, but it gets me from A to B).

My Question is what else can I do to my engine to increase the Hp and Tq? I am plan'n on add'n a High-flow catalatic converter and an HP Racing Cat-back Exhaust. I dont really want to tear the engine appart right yet, because I wont have a car to get to work and school in so I guess my real question here should be what other mods can I do to get some Hp out of my engine w/o having to take it apart and replace all the internals?

I hope that I've made some sense

 

I have a ported intake manifold and a big bore throttle body for your motor. The gains are usually 7-9 hp. email me at polarbeartuning@yahoo.com if intrested. I also have a cam grind that works well with the d15b motor.

 

mini-me will be the best HP gain for you...20-30hp gain.

min-me is basically a d16z6 vtec head on the d15 block. It doesnt appear to be a ton of work...there are a few write ups on the boards....check'em out.
