My 850 wagon is the replacement for my C5 Corvette six speed roadster, so leaving this thing compleatly stock is out of the question. It is still in the planning stages, but I have in mind something like the orange 850 in the uTube video. The thought has crossed my mind to put a 300hp R six speed setup in the car, but unless one falls in my lap, that won't happen. It may become more practical soon when the new Volvo 227hp six speed coupes start to hit the bone yards with their drivetrains on the block.
These cars should respond well to some simple hotrod tricks like K&N filter and free flow exaust. Lowerd racing springs, good shocks, heavy duty sway bars, bigger brakes and fat tires should make a huge difference, even with the stock motor. We will see how it goes.
