Hello EvoM!
I'm planning to buy GSC S2 cams which will runs with stock evo 9 turbo.
I research some posts, and did not get a quite answer.
Do you guys recommend buying GSC stage 1 valve springs, or is it okay to run S2 cams with stock valve springs ?
Thanks!!!

 

you should get upgraded springs with those cams as they do have pretty aggressive lift.

 

Thanks for input!!!


What do you guys recommand for valve springs and retainers ?

 

I have the S2s and I used the gsc beehive springs.

 

Yes, do them.

Spend the extra few bucks and get the best:

I'm running S2's on stock valvetrain.

 

Then my post goes for you too

But seriously..in the upper RPMs I would imagine you're going to experience some valve float on stock springs.

 

Well I spoke to 2 turners and they said that because im on the stock turbo and run out of steam before redline, there is no reason to move the redline. So the stock vavletrain is good for now.

 

I'd do upgraded springs at a minimum. If you do not want to do springs I'd go with S1 cams. Springs are less than $200, may as well do it right.

 

Upgrade to GSC single beehive springs anyway.

They are not that much more expensive compared to having to install them separately down the road if you upgrade further. Do it right, or do it twice...up to you

Although, you are on the stock turbo, it is recommended to upgrade the springs, especially the S2s because they have quite a big lift. You will take more advantage of the cams with upgraded springs, especially if you upgrade further down the road. Good luck

 

Just for my imput can anyone show me pics of the difference between teh stock springs and the beehive ones? I have gcs stage 2's and I would like to see the difference between the stock springs and the aftermarket ones.

 

they look almost exactly the same. The difference is in the spring tension in lbs.

 

me personally am gonna run the s2s with the GSC beehive springs and titanium retainers i figured might as well spend a little extra to make sure that its strong and safe

 

According to inputs, I should get the GSC beehive springs at least.

 

well taken from GSC power division website, they said "or can be run at the stock revlimit and factory boost on the stock spring"

so given that, i went ahead and got the beehive/ti retainers because im already paying to get cams installed, and the valve springs are right there, shops dont charge but a lil more to do the valve springs too. so, again what most people said and is true, do it right the first time.

ur getting cams, i doubt ur gonna stay with stock boost and rev limit... i thought i was but that was bull$hit, i had the tuner up the boost and stretch the redline. lol

i would suggest u get it and it'll be safe to up the boost down the road. rather than be worried about valve float.
