Go for it if you're in for the adventure. Most people who want to convert don't realize the things that are absulutely necessary for the conversion however?

Depending on how much power you want to make, this can include larger injectors, and ofcourse fuel management, timing control etc. After that you'll still need all the "custom" plumbing for the turbocharger (oil/antifreeze feed and drains). This is ofcoruse not to mention the need for custom exhaust plumbing to and from the turbo, againf or the intake, to and from the turbo. This assumes you'll let the turbo hang from the exhaust which is OK but you'll need either a very short, or a very, very strong manifold. Stainless stell is advisable to use for the exhaust manifold for durability and longetivity reasons, which is expensive and hard to work with. Ofcourse there'll be a lot of vibrations and there needs to be slack left in for expansion/contraction of parts. Or reliability/longetivity will suffer.

I will go so far to mention that if/when you do have a problem with your turbo conversion it'll be YOUR problem, and you won't be able to get much help from places like this board, or the PCA or Porsche publications like excellence, etc. Ofcousre you still need to adequately shield certain parts from heat.

If you have an earlier 944, when this is all said and done you will have a waterpump that moves less coolant, a smaller capacity oil pump, smaller oil galleries etc. Need I mention no oil cooler, and smaller radiator regardless of the year of your 944. Most 944 turbos come with strengthened gearboxes, mine has a transaxle cooler also, this is not to mention several stronger/improved suspension parts, clutch etc. to cope w/the power. Ofcourse your brakes/suspension as they are now will, if you plan to drive your car hard, need to be taken care of also.

This is an opinion ofcourse, and there's more than one way of doing things...
