Jim so far with 7 lbs of boost it has, but with 14 it took out the CV joints the second time I took it out. I hope it holds up thats why I dropped the boost, the input shaft on the VW transaxle is a little on the skinny side. I just drove it 2300 miles without any problems so if I continue to be kind to it, it should last.
Jack is right the NA motor will be plenty for a light car, my Vanagon is pretty heavy, I think 4200-4400 lbs.
Oh I have a 5 speed transaxle for the subie if anyone needs one, its good shape but it would be impossible to flip the ring and pinion in it or I would have used it. As Jack said it would be perfect for mid engine car. Its the all wheel drive model but all you have to do is pin the rear output and it would work great.
