Just bought my first Tacoma. 2002 TRD Supercharged crew cab 188k miles. It has a burnt exhaust valve on #3. I have it torn down already. Planning on all new exhaust valves, timing belt/water pump, new gaskets and supercharger rebuild. As far as I know, a burnt valve is typically caused by a lean condition, which makes sense with a supercharged engine. Do they make bigger injectors for this engine to eliminate this problem? I would like to put it back together better than before but I guess it ran for 16 years like that so another 16 is acceptable.
