The Mitsubishi Eclipse stands out as one of the most modification friendly applications out there. These cars were introduced in 1990 with the AWD GSX and FWD GS-T models. They have been known to produce massive amounts of horsepower with their 4G63 power plant and are the perfect application for a very fast street or race car. The aftermarket support for these cars is among the largest in the industry and Eclipse owners can literally replace almost every part on the car with a aftermarket version. JSC Speed carries a large selection of performance parts for the 4G63. We have everything from intakes and exhausts to camshafts and engine internals. We can provide you with anything you need to make your Eclipse into a monster!
