I have the same engine in a 93 Four Door, You are gonna hear a lot of people telling you to swap the engine, The D1b7 is not a high performing engine, however with some bolt ons you can have some fun. I am currently doing an engine dress up on mine then I am lookin at puttin a header on it with a better exhaust system than the make shift one I have now lol. If you don't know a lot about engines you may want to find some people that currently work on hondas, hang out and get dirty toolin' on some cars it is the only way you will learn. There is an option to slap a Z6 head on the d15 block to make your honda a vtec and then you can look at goin even faster. It is all about how serious you are. Do you have pictures of your car that you can post? And what do you want out of your car?
