Installing a set of camshafts

[thehunterooo]

So my new plan is to have my header, underdrive pulley with my new gatorback belt, and rabbit's set of coilover installed over spring break in the middle of march, along with the CF hood that I will do myself.

If we are able to get a group buy on them or if i can get a set some how (camshafts), what will have to be done to install them? Will I be better off doing the timing belt then as well? Should I also look at replacing the valves with some better made one? I was going to call the shop and see what they think but I wanted to ask you guys and rabbit, I am not sure how a camshaft install would go for the aveo, or what you would have to do/time it takes to install them?

you might have to pull the engine out to be able to install the camshafts

[petrified.rabbit]

you do the camshafts, with the timing belt to eliminate over lap (have to take the pulleys off with the timing belt and cams).

you take the valve cover off, and then you take the cam caps off, and pull the cams out. i would probably suggest pulling the spark plugs, since you would be pulling all the valves in.. make sure your timing is perfect on them when you put it back together.

if you do it, you might need better springs, which you could probably find through the shop that makes the cam.
there are quite a few shops that do this if you dont mind regrind (nothing wrong with them really, best bet for the money).

Yeah, I forgot about the springs and retainers as well, does not seem to difficult then, a lot less work then what I thought, so it would only take a few hours if everything comes out right and goes back in right?

Any way, if you really want to make good use of a new camshaft you will need a custom programing of your ECU, not worth it if you ask me...

[thehunterooo]

Xaio did it without it at first, if it will run right with them in then I will worry about it at a later time, I wish there was other ecu tuning options besides piggybacks but that is what I am going to have to use. No one even wants to buy underdrive pulleys

[MatLax]

Just waiting a bit for money before I buy mine :P

Depending on what you up the duration to.. The computer can adjust.

All cams do (generically) is change the amounts of air able to be feed into the engine at what rpm, as long as you dont go beyond the sensors acceptable Limits, the fueling will be added to match. Also if the chip we've been talking about works, then that will multiply the power from the cams.

Ideally you'd want to optimize ignition timing too, but thats not a huge deal. You might have a bit of retard that isn't needed. However, I'm not 100% sure how most modern ECUs attempt to optimize timing vs using the knock sensor. I imagine they have to set timing they try to hit and if the knock sensor activates it backs timing off.

That also corssed my mind as well, if that chip is added, the power would increase a lot more.
