Thanks guys.
The beauty of building a bastard Porsche from a Superbeetle is there's no sacrificing the value of the car when you deviate from it's stock equipment, like there could be with a pre-'68 model. Beetles with front struts were always VW's red-headed stepchildren that got laughed at even by the Type 3 guys, so there's no more shame in modding one than there is in outright ownership of one.
So much of the 924's chassis, and by extension, 931/944/951/968 came from a VW 1303S that it makes a Super the perfect platform from which to start building a fun, and fast air cooled car for a fraction of the cost of extracting similar performance from a 911. Many of the brake, and suspension parts that I used were ones that a 944 owner would replace in order to upgrade their car, so the prices for the core parts are very reasonable.
The engine cost is another matter if you decide to build a Type 4. You'll spend that money you saved on the brakes and stuff, but it's nice to have 100 lbs of torque at 2200 rpm, and a 5 speed to make that torque available anytime.
