i wanted to do some mods to my 92 dodge stealth. The engine has 175k miles. Does it have too many miles to do some mods to it? Or should I just buy another stealth/VR-4 engine and have it replaced and then do some mods to it? I was thinking on buying a new stealth/3000gt but it will cost too much money. Would it just be cheaper to buy an engine by itself and putting it on my car? The reason why I want to keep the car it's because the body is in good condition and it is pearl white.
