Hey,

i just bought a '99 prelude and its automatic but i still want to make it a powerful car and i wanted to know what things i could do to make it quicker  

AEM V2 intake,Greddy Evo2 exhaust, high flow-cat,Dc 4-2-1 headers, run u about a G but its a start  

how much hp should that bring me up too?  

Depending on how ur car runs n how good the engine is It'll give u a boost about 50-75hp range  

thats a big hunk of *** u will not gain anything near 50-75 hp. i dont know what glue uve been sniffing but every one know h22's dont respond will to simple bolt on's u might get 20 hp (MIGHT if ur lucky) but dont get me wrong it will change ur dyno curve completely and ur lets say 225hp will hit a hell of a lot stronger  but u wont be geting huge numbers for a h22 with a full exh. and intake  

well tytank7 im still going to go ahead with waht ludeh22a said because u havent given any advice on what i could do but also im planning on getting a chip for it. but if u could give some helpful input that would be good.  

Well i have the same car N honestly after i installed the exhaust n intake was alot quicker n ofcourse I said it was a start...mine still has more mods in it n ur still gonna have to get it tuned
