Walt I have not idea how many twin turbos are running around out there, but it must be a bunch since it is the only currently advertised kit and has been for some time. One of the problems with the kit is that it requires moving the alternator to the top of the engine and this means removing the intake air tube. Thus, air is sucked into the existing "air box" right at the filter, sans intake tube. Result? HOT air. The intake is now directed toward the bottom of the car (read exhaust manifold). An intake unit that would bring in colder air would be a big plus. Add a K&N filter and a stainless housing and I think you would have a hit. Just another suggestion - - I bet you are getting plenty of them. Dick Ryan VIN 16867 __________________________________________________ Do You Yahoo!? Get personalized email addresses from Yahoo!
