good or bad?

why cant one use aftermarket cams with a turbo system?

 

you could

 

even a stage II cam?

 

you could use them, but why when stock cams already work very good with boost. money is better spent elsewhere if you want more power.

 

I was curious about the cam question too. Alot of People were switching to GSR cams for there turbo apps.

I agree though they are making great power why upgrade them.

i already have skunk2 stage 2 cams.

someone told me to get rid of them and go back stock cams if i am going boost.
just wanted to know why

..if your going boost use type R cams. there proven to work well.
then if u want more power get a bigger turbo and turn up the boost.

 

should i take out the skunk2 stage II cams and put in the stock cams?
or it can work with a turbo?

 

compare them to ITR specs, and if they are similar, then i would run them.

If u have to rev higher to gain the power, then i wouldnt hesistate to do so, but thats me.

 

yea t he type-r make good power but there are so many cams out there that will work better. it just hasn't been nailed down yet its all abt the set up. you just gotta go out and experiment and for the price you pay for some type-r's i would just spend a tad more and get aftermarket. but since you already have cams just leave them in there, get some cam gears and play with them while your on the dyno to get the best power out of them

 

tune the cams before the turbo?
or after

The stage 2 cams are meant for an all-motor application. This means that they have a longer duration (in simple terms, they hold the valves open longer). There is longer valve overlap (time in which both the intake, and exhaust valves are open), which can be bad on a forced induction application. Ideally, a turbo-charged motor would run cams that open the valves higher, but with less overlap. I think stock GS-R cams or ITR cams are a good candidate for boost, but getting into stage 2 N/A cams may be pushing it. Ultimately, with a good tune any set of cams can be made to work... but the GS-R cams are typically going to provide the better power-band. Good luck on your build.

 

thanks meng, thats was the answer i was looking for.

 

I would use the skunk cams if u allready have it, the overlap can be reduced with adjustable camgears.

also remember that if using an equal lenght or top mount mani he could take very good advantage of those cams. now if he was to use a log manifold then yes you are correct. but the equal lenght cam make very good power with big N/A cams and can also improve midrange and top end. and sometimes it does help with spool time.

Another good point. How would topend power be at a high boost level, with the turbo heaving air straight through both open valevs? I know there is no absolute answer here, as each motor combination is going to yield different results. I enjoy discussions like these.

 

it would help cause it fills the cylinders with all new fresh air. because regardless of how long the valves stays open the turbo is going to push as hard as it needs to in order to keep the boost at the desired level. and also have to agree with you that every motor comb. will be defferent so its all abt getting to know what works with your specific mods
