xtra power for a 91 2.5 L

I,m looking for headers,a new air filter,and any other ideas to up my horse power.its a 91 2wheel drive 2.5 L and a 5 speed manual.any and all help is appreciated.also I'm on a low buget

v8 is the only option :P

i have a friend that has a 2.5L bored .060 with a header, catback, computer chip, intake, and a list of high performance goodies. he has invested way more in the engine than he could have upgraded to a V6 or V8 for. his truck runs pretty good but not worth the money. save your money are do an engine swap.

swap for a v 8, 350 or 386, local junk dealers are your best bet, if your good buy one and rebuild it
