Camshaft

17th September 2012, 21:40

Thinking about camming my car as I was talking to someone at work who said the tappets are fucked in my engine. Apparently you need to take the camshaft out to change them so I thought while it's out I might aswell replace it with a better one. Also got told a new one might come with new tappets and stuff too.

I'm new to modifying engines, furthest I've gone is 4-2-1 manifold straight through pipe and back box, all supersprint, and an induction kit, so just breather mods.

I've just seen this http://www.saxperience.com/forum/sho...d.php?t=434969 posted but I was thinking more like these http://www.kamracing.co.uk/citroen/c...camshafts.html the top ones.

I drive a Saxo VTR 02, is mine a none roller or roller? Also Silver top or Blacktop?

Also seen as I'm new to it I don't know good makes of camshaft or bad. Also looking to remap it once it's fitted.

Any help would be much appreciated, thankyou for your time.

What's the difference with the black top and silver top? And what's a roller rocker?

Thanks mate

Black top is the earlier VTR, using a conventional rocker arms and harder valve springs.
the later silvertop had roller rockers and softer valve springs available in 90bhp and later 98 bhp.
The 98 silvertops got a different inlet port design too. Softer valve springs as standard means the valves have a tendency to float at higher revs, but they are easily enough to change if you are going to be pulling the head off anyway to swap the cam.
Black top setup is usually the one people pick for if they are into getting performance from an 8v

So why do people chose to modify blacktops over the silver. Is there more of a perfomance gain or just easier to do?
