I would like to know this, now I have a SC 50 .63ar who can push on the top-end, and my head and my engine could be rev at 8500-9000 ( maybe more but I want to be realistic ). So do I have to change my cam or it will be ok ... I heard or read many story on this so I just want to make this clear and many D owner would like to know this ....

And if I should change I would like to have a cam who keep a good idle too ....

Thank Mat

 

pleaaaasssse

 

I am sure that your turbo will make power as far as you want it to within reason. The things your going to start running into is valve springs retainers and valves are going to be an issue. And if you are going rev that hight with a motor that doesnt stock. You will need rod bolts head studs ect.....Look into the all motor section. They know everything about 9800 rpm ect....As far as the cam is concerned i think it may break if revved too high.

 

my head is fully built ... spring, retainer, valves... my engine too ... I just want to know if my cam is designed to produce power in this rpm range ...

 

i think u'd need a better cam to make power that high on a d series but that just my opinion...

 

ok but I need more than just an opinion ..... I need people who tried this before...

 

If its a stock cam then no.

 

mmmh ok thank ...

 

You dont NEED a cam. Your turbo will continue to make power aftermarket cam or no. From the basic specs im sure your turbo is going to pull well into the 9k range. If you did change cams, you would see a benefit even if it stoped making power at 8200-8500 rpms. The stock cam is by no means designed for the rpm range your shootin for, or forced induction for that matter. It will work, but eventually you'll want to upgrade just to get the power.

 

ok this is what I was thinking the cam will *follow* the turbo loll

 

waste of money, it makes like 10whp

 

eheh thank to tell me this if it is really true... anyway... many good whp have been made on stock Honda cam ...

 

Are you guys stupid???
You don't NEED an aftermarket cam to make power to 9000. BUT and I do mean a big BUT, if you want to make more power at 9000 then go with an aftermarket cam.
For example a stock cam with valve springs and retainers done might give you, let's say a 10hp gain at 9000, but an aftermarket cam with higher lift and low duration would probably give a 20hp gain.

But the answer you are looking for is no BUT you could upgrade

 

ok thank ....
