In a standard 98 EX you get 127 hp. Is it possible to modify it without too much cost to get the 160 hp the SI is rated for? Thanks -- Doug

u could get an air intake or a cold air intake they add up on HP. i think like 7 to 15 horses it depends on which kind u get. then u could get a sport muffler and take out the factory muffler and factory silencer and add straight pipe from your catalitic converter to the sport muffler.<br>that all i did and i can keep up w/ Si's<br>and mines an 1998 EX.<br>hope i could help <br>RiK<br>aka<br>BONES

You could add alot of things to get the HP you want.... the mod chip will give you another 10 HP or so, headers - another 7-10 HP, intake (cold air or ram air) another 7-10 HP, exhaust system (I prefer the TCS) another 10-15 HP... <br><br>also, you can get the Si mods... different pistons (bore and stroke) and heads.... <br><br>a better suspension and short shifter will make your EX handle better and shift better....<br><br>hope this helps...<br>AC

You definitely cannot use any of the internal motor parts from and SI including the pistons, Also on your car the headers will give you like 3hp a cold air intake will give you like 7hp and exhaust maybe 3hp and a mod chip will give you practically nothing since all the chip does is re map your air and fuel curves but since you didn't really modify your car that much in the first place the stock ecu will be able to handle your new mods perfectly
