Thinking of going for a gsr induction and cams upgrade pretty soon...who manufactures fast road/rally cams or would be willing to re-profile cams for the 1.6 16v stilo?
Do C&B do them?

As I told you on PM.. CB cams are the best not regrinds and built specifically for the engine..its just hassle getting hold of them..
why would a manifold render a cam change useless?
its all too technical for me to understand fully, i was in the middle of a conversation between a group of tuners and exhaust makers the other night, and this is what they was all talking about, i will try and get them to explain it too me in a way i can remember and type
do you intend to fit a 4 branch manifold in the future? if so then off the shelf cams will be no good for you.
there is a 1.6 stilo gsr kit in classifieds
Sorry but that is wrong. As a change of cams will allow the engine to breathe better, if you then change the restrictive air intake and change to a 4 into 2 into 1 exhaust manifold it will make better use of the cams as the air is able to get into the engine faster and it is also able to get rid of the waste gasses better as well. the cam timing might need to be altered slightly by use of a vernier pulley to make best use of the better breathing and also some time on a rolling road so that it can be set up properly.
You will never get very good results with an aftermarket of the shelf cam and an aftermarket off the shelf manifold. This is fact.
why would you want to mess about with vernier pulleys and stuff when you can just get a cam machined right in the first place to match a manifold that is also right

So off the shelf cams are designed to give more performance and keep the engines reliabilty.
No not designed to suit the manifold it is just there to get he exhaust gas out, the performance cam is designed to get more of the exhaust gas out by holding the valve open longer. They may well be tested on an engine with a cast manifold and show good gains. When you then change the manifold to a free flowing tubular one that is designed to give a good comprimise between power and torque by using a 4-2-1 design the engine will be able to breathe a lot more efficiently if tied in with a good freeflow air filter thus producing more power and torque.
Any way i think i have now said the same thing enough now so i bid you all good night. :bang:
And please lock this post
Ps: For the initial poster get the C & B Cams as they are ace then get a nice SS manifold when you can and a remap your car will go so much better if you do. and remember to upgrade your bake pads as well since you will be going faster
you obviously have no idea who oldschool is, or what he does
