s12 mk1 and mk2 engine

Sure it came from a 1.8 turbo, but works with my motor; more than 2 months i ran with it .

I even saw CA20E with mechanical valve system.

OK, well what cam has it got?

I can tell you now the CA20 cam is crap. The CA18 cam in the CA20 head still isn't at its best, unless you use the different ratio rockers from the CA18.

Francais :

Quelle cam a t'il ?

Je peux te dire maintenant que le CA20 cam c'est de la merde. Le CA18 cam dans la tete du CA20n'est toujours pas la meilleure solution, a moins que tu utilises un ratio different du CA18

Yep thats a CA20 head all turbo s12's came with adjustable tappets.

Can I go 10 psi with it?

Yes but using a CA18 cam and rockers would be best.

Oui mais ca serait mieux d'utiliser un CA18 cam et rockers
