need some advice for D15b

[jbluesi]

i have alot of questions that need some answering. I have a d15b in my 92 hatch, i was wondering what parts i could put on it to give it some more go. Is there any internals from the regular si that would fit, like springs / valves / retainers cams ? I have an msd ignition and underdrive pullies on the way, header and plug wires comming soon, i was wondering, i heard alot of negative stuff about underdrive pullies, are they worth it or should i sell them when they arrive ?? i heard also that i should leave my crank pulley alone, and i have bosch platium 4 plugs in it now, are ngk iridium better

it helped, but i could still use some advice on the other bolt ons, are they even worth it ?

intake, header, exhaust, and chipped ecu on a mini-me. That would be a good set up, i dont know about the head internals and all that stuff but maybe you can get pistons out of another engine that will raise your compression ratio(dont know out of which engine, ask around), then youll need to use premium gas depending how high your compression is but youll be making a nice amount of power N/A.
-mini me
-I/H/E
-chipped ecu

i have put headers, cat back, better plugs, wires, fuel pump, annd cold air intake on my 92 hatch with a d15b and i havent seen too much improvement in the power out put of it, i have decided to swap in a sir motor once i get back from iraq. imho the d15b wouldnt be worth the money to fix

I just bought a 92 civic dx hb, It has a d15b engine and-- has an Si sohc head on it (d16), it all fits just perfectly nothing else needed. It hasent had anything done to the ecu (but I dont know much yet).
But as of now I know some things you can do to your d15b --
Si head, header, cat back exhaust (large), cold air intake. I would say next would be get a hotter spark- plugs and wires.
