    1989 highly modified 951.
  1. Even for cars as recent as the 996 Porsche recommend 20w/50 in their owner's manuals. Using M1 anything, let alone 0w/40 is a definite NO in older cars inc 951s.
  2. On a track like that, or any track really, you should be using at least a 20w/50. We use a 25w/60 on the track. I would not use that brand either. Look for something that contains high ZDDPs. Use the internet to read about these. Very important on our era of cars.
  3. You can fit 18x9 / 18x10's provided you get the right offsets. For the early models with lower offset you will have a really nice deep dished wheel, but will possibly need to have them custom made. Don't forget things like size of brake rotor and calipers, lowering, neg camber can all have an effect on wheels too. Best to go to an expert for advice. If you're going to track the car, don't buy some wheels just because they're cheap. A wheel failure can be really bad on the track...really bad.
  4. http://www.customengineeredperformance.com/ Try Dave McGrath. I know he's doing something about this for his own car and will be looking at selling these as well. I'm looking at getting some too. http://allporscheracing.com/WBody.html Also try Mike at IFC. His kits are meant to be the best fit and finish out there, but not sure how race oriented they are. Definitely nice for street though.
  5. 0W40 would be catastrophic for our cars unless you're in the arctic circle. 20w50 is perfect. We use 25w60 for the track.
  6. Can't be done for $8k unless you do all the work yourself and even then you will have to do so many connected mods as stated like suspension and brakes. To get 450whp reliably almost certainly requires a greater capacity than 2.5L. You'll need a bigger turbo, probably a GT35r and what about the ems? Look to spend double that and more. With all due respect you'd be better off posting this question on Rennlist. Sorry. You'd be better off re-evaluating your goals and starting off in a class that you don't need such power. Have you driven or been in a 951 with even 300whp? That's surprisingly fast. 450whp is rocketship fast and requires some level of skill to drive as well. No disrespect intended.
  7. You need closer to a 60et on the backs. Spacer will only make it worse. You're not going to be able to fit them unless you do some bodywork. Sorry.
