dose any one know of any engine upgrades that would work for my 94 3.0 v6 shadow?

52mm throttle body from 3.3 with one of the vacum ports sealed off, colder thermostat to make the engine run cooler ( get an 180 degree), Bosch platinum plugs, a K&N Mustang 5.0 cone air filter hooked to the throttle body, advance your timing about 12 degrees (MUST RUN 93 OCTANE GAS ALWAYS IF YOU DO THIS!!!). These are a few that come to mind, and should bring you to knocking on the 200 horse power door.....GOOD LUCK!! Let me know how it goes!!

I got a set of BRAND new ported, polished, and decked heads for sale. 500 bucks worth of work done from J-B Machine shop here in Maryland.

hello, you sugested the possible power upgrade for the dodge shadow , about how much would that cost me to do?
