I'm interested in getting a Stage 3 camshaft put into my 4L EL Ghia from the blokes at CMS.
But...
I'm not sure if it will be a straight swap of camshafts.

The "Stage 2 Cam and Head Package" contains:
Quote:
"CMS Stage 2 Head & cam package is a great intro for your i6 performance upgrades, defiantly a great “bang for buck’’ deal, guaranteed increase in torque & power.
What you get is....

Fully serviced head
New heavy duty valve springs
Oversize exhaust valves Ports deburred (only)
Reground stage 2 cam & shims
New vernier cam gear

Inlet & exhaust mods are recommended as part of your upgrades, this package is also ECU friendly and has a near stock idle.......a proven performer!"


Now, I'm very certain that is what I have.

But, being power thirsty and a stereotypical teenager, I yearn for more power and a lumpier idle, so I'd like the Stage 3 CMS Camshaft.

The thing that points me in the "No mate, it won't run... dcikhead" direction is that the Stage 3 Cam and Head Package says:
Quote:
"CMS Stage 3 Head & cam package is one of our biggest sellers. The huge gains due to its specific porting make this a favourite and is still great value for money & a must have in unlocking that extra hp!

What you get is....

Fully serviced head
New heavy duty valve springs
Oversize exhaust valves
Minor & specific Porting
Reground stage 3 cam& shims
New vernier cam gear

Inlet & exhaust mods are recommended as part of your upgrades, this package is also ECU friendly & has a lopy idle, ISC & TPS mods are required.......a proven performer!"


Am I in over my head (pun) or can it be done without too much hassle?


TL;DR:
Can a Stage 3 CMS Cam fit into a Stage 2 CMS Head?

yes, you can run the cms3 cam in the cms2 head no worries.. the cms 2 head already has decent valve springs to handle the 3 cam..
not an auto friendly cam though..

wont idle well in gear and will not perform untill around 2800 rpm, almost like having lag without having a turbo..lol

would work real well with a high stall or much shorter diff gears like 3.9:1
