How and what do you need to do to upgrade a camshaft? I'm not going big, just stage 2. I was woundering if i could do it myself with the right tools?

 

with the right tools you can do it, its basically a timing belt job, while you are at it, change the cam seal and check the condition of the crank seal and waterpump, and adjust your valves after that

 

dont forget about changing valve springs, retainers, and valve keepers

 

will you need to do it on a stage 2 cam....

 

generally on stage 2 cams, they recommmend you replace valve springs and retainers

 

they said on the web-sit that you dont need replace anything, is that true or not? and if it is, would i be better of with a stage 2 or 3, if i have to change everything any way?

 

jesus, just cause its a bigger cam doesnt mean its what you want. Say a stage 4, you would end up loosing 10 hp in your daily driving rpm.

Save yur money, get a stage 1, its all you need/want in a daily driver. Power can be made else where and you keep the driveability.

 

and what web site is this?

 

the crower web site

 

generally, if the cam is mild (i.e. Type R, or stage 1 aftermarket) you dont need to change the valve train, just dont rev it much past stock rev limit, i'd say 8500 would be okay.

If you have a bigger set of cams, you need the upgraded valve train to handle the aggressive lift and to prevent spring binding, and most importantly, to handle the higher revs where you'll be making power.

I have personally seen 2 stock block b16s revving to 10,000, although not daily, but occasionally. I've also seen a kid with a b16a SiR1 chip his ECU, rev the engine to about 9800 with stock cams & valvetrain, and a retainer broke, dropped a valve into the cylinder, and completely destroyed the block and head. The block isnt the weak point, the valvetrain is.

If you want piece of mind, upgrade the valve train and have nothing to worry about. but if you're on a budget, a stage 1 or type r cam set should be fine with stock valvetrain.

 

thanks for the advice....i'll probably replace the valve train..it would be a great piece of mind.

 

does anybody know if there are any specifications or anything that i have to know when replacing these parts?
I wana do the swaps myself, i cant afford to take it to a full blown mechanic to do it, they charge too much.
