So i bought this car for 1000 bucks. I bought it because is drove awesome, I think it has a rebuilt engine or the top end atleast because it drives smooth, no ticks in the engine or anything. The body has 300k miles on it. Anyways, I want to make the car faster. I can do all work by myself with the proper steps. Im not knowledgable on the engine codes, D-series, B-Series etc... I looked it up and the engine the DX has is the D15A2 which doesnt have much horsepower at all. Without swapping the entire engine out for another one, what can I do to the stock engine it has in it? I also want a website or a book that will tell me everything there is to know about Hondas and the engines, swaps, specifications, etc... so I can learn about it all. Is there such things? Like a Honda Guidebook or something like that? Excuse my lack of knowledge, I've always just fixed cars, Ive never suped them up, or swapped angines so I dont know what engine fits in what and if it doesnt fit, what to modify. Hopefully Im not confusing anyone. But thank you for reading this post.
