I tried searching and just kept coming up with dyno reults and impressions. I want to know when installing cams (GSC 272, 264) if I should replace the timing belt, tensioner, etc. I'll be picking up new injectors, fuel pump, cam gears and head studs. Just want to know what stock parts to replace basically. Thanks.

 

I don't think you have to replace any of the stock parts. Some people will probably tell you it's a good idea to replace the belts.

 

It really depends on how many miles you have on the car. Over 20,000 and I would probably replace the tensioner. If the car is still somewhat new, then you shouldn't have to replace anything.
