Title: Camshafts
Post by: LoneWolf on May 27, 2008, 03:38:16 am: is a 1.5 N/A diesel camshaft different to a 1.6TD camshaft?

Now, that's just going by part numbers. I've been told you can run just about any ca in any model. So, mechanical cam can be run in a hydro head.

I'm currently running a 1.9 TDI cam in my 1987 1.6NA. It works fine in terms of idling, but it seems to be light in the torque dept (high lift, short duration, vs. less lift and longer duration).

So, I guess the bottom line is, try whatever you like. I don't think it will do damage, except for changes in power, torque or economy.

Please correct me if I'm wrong out there.

I can't confirm or deny this though. Turn the engine over by hand a few times first to be safe.
