Hi..

The question is this..
I´m thinkinig of replacing my cams with the cams from the C5 engine because I´ll get them cheap from a friend!

But! Do I also have to replace the vaultssprings/vaults and more?
Or can I just mount the cams and drive?
Does the stock C1 vaultsprings/vaults handle the power of the C5 cams or will the engine fail???

 

you do not have to replace the valve springs. i would suggest a pair of cam sprockets so that you can fine tune the cams.

 

So the C1 vaultsprings can handle the power from the C5 cams without failing?

 

You can get R intake valvesprings, and move your existing intake springs to the exhaust side.

 

Clabbe, hows the weather in Stockholm right now? I'm going to Uppsala in a couple weeks.

Sorry for the thread hijaking.h:

 

Sun is shining!

 

I deleted a few of the offtopic posts. Let's try and keep it clean.

ITR cams will be OK with stock valvesprings if you use the stock GSR redline, not ITR redline.

 

So I shouldn´t rev the engine pass the GS-R redline?
But that would be almost impossible!
