If by bolt-ons you are referring to intake/header/exhaust, underdrive pulley, spark plug wires, etc. then you're looking at around 110 whp max. with the right choice in parts, but that's about as far as you will go. With an MP3 ECU you might even get as far as 120 whp but even that's pushing it.
My MP3 had the following mods....
AEM Short Ram Intake
Sparkco Plug Wires
2.5" Hydro Bent Cat-Back Exhaust
TB Coolant Bypass
AWR A/T F & R Motor Mounts
and it pulled 116.7whp and 122.6ft/lbs on a dynojet so i think 130-140 with more mods such as header, test pipe, mandrel bent exhaust, and underdrive pulleys would be obtainable, then if you wanted to get into some mods such as swapping a mp3 intake mani and porting it out, adjustable cam gears and some sort of engine management im sure u could see 150whp easy. the adjustable cam gears and engine management would net your largest gains.
