Are you just putting together a nice road car or are you going to track the car? If the latter, then you need to form a plan and get lots of advice (if you haven't already). It will save you a lot of money, time, and heartache...believe me.
Where did you pick up your 924 Carrera GT Head Lights? I would like to buy a set to save on weight and look 100X better. Your car is beautiful. Thanks.
Hmm, well I'm not so versed on the n/a but exhaust, chips would be a start and there are different cam options too. The easiest way to make it go faster is also to lighten it, but I don't know what your intentions are with the car. Best to go to some of the 944 na sites. Sorry I can't help further.
saw the description of your car, awesome. Im a porsche newbie, just got a 944 88 NA 5speed manual, a couple months ago. What would be some relatively cheap performance upgrades you would consider in such a vehicle. I have access to Porsche experienced mechanics and have the service manuals too.
