  1. Jasper Performance Engines Rebuild

    MKIII (1986.5-1992)
    Today a friend of mine recommended sending my engine in to Jasper Performance Group for a rebuild. He claims they can make a 7M-GE gain 50hp more than stock form for a price of $3k plus parts, with a 3 year 100k mile warranty included. It sounds too good to be true. Does anyone have experience...
