Make sure you buy ALL of these other parts too:
After all, why re-invent the wheel when it's already been done before. At a minimum, you'll need the following 951 parts to convert a 944NA to Turbo:
$900 - headers
$300 - crossover pipe
$200 - turbo wastegate & dump pipe
$400 - KKK turbo K26/6
$250 - turbo coolant-pump, piping and coolant tank
$500 - turbo/engine-mount, oil-plumbing and oil-pan
$500 - exhaust downpipe, catalytic-section & cat-back
$600 - airbox & air-flow meter (AFM) & J-pipe
$500 - intercooler & pipes
$300 - intake-manifold & throttle-body
$100 - Turbo injectors
$300 - Turbo head
$350 - Turbo cam
$500 - Turbo forged pistons for lower 8:1 compression
$250 - Turbo forged con-rods
$700 - Turbo DME/KLR computers
$100 - Turbo wiring harness
Eventually, you'll have bought the entire package piecemeal as the 944NA parts wear out, and quickly too... Within a year, you'll need:
$1000 - Turbo complete brake package
$900 - Turbo suspension
$1500 - Turbo rebuilt transmission (don't ask how much a new one is)
Here's photo of what happens to a 944NA tranny after it's been used in a 951 for a year:
Ok, so you can save a little by leaving off the really unnessecary stuff like the front nose-panel, rear wing/valance and those little side-skirts.... But then again, wouldn't you really want people to know that you have a Turbo?
