Putting in springs not the same as just replacing cams. So its not a while your in there thing. Yea u can add compressed air to cylinder and replace springs but if u lose that air for some reason and valve drops head will have to come off

 

On briancrower.com it even shows oem springs ok. Ill consider it at this point. Lol. Cams not in yet. Won't get them in untill I get fmic in and $ for tune which could be june but ill be sure to post results and what is actually done.

 

wana see the results of your set up. hope you can get at least 20 whp on the new cams maybe more. should feel a pull through the entire rpm range.

 

That's true, but also RPM depends on the rest of your drive train, not simply just cams. Your bottom end won't be able to keep up.

That's true, but to me it's kind of like turbo and manifold. They're not the same task, but they're related enough that if I'm replacing the turbo, I'll tackle the manifold as well (assuming end goal was to replace both).

But yeah, dropping a valve isn't ever fun :P

What cams are you planning to use?

 

I have the bc 272 on the way but wont put them in untill have rest of $ for tune and fmic I have enough time to decide if I use springs or not . Again its a dd and I have built a few evos more 8s and 9s tho mine would be the first x I touch. I have built other cars such as 600 plus hp chevy camaro with cam , springs push rods injectors and supercharger then they went and got meth put in and 700hp later car still runs good but is way to much for dd. Im looking to in crease hp but wanna be reasonable for dd.and replacing mainfold while doing turbo still not same as doing valve springs while doing cam.... turbo and manifold would more be like replacing timing chain while ur doing cams . Either way the cam is not that big to where the bottom end wont be able to keep up .

 

Thoughts on kelford stage 2 cams for a 2.2 bore build with bigger turbo? Stage 3 cams a better option?

 

if you are planning on building and doing bigger turbo later cams will be worth it I saw kelford c cams with springs and retainers.
If you are planning on keeping the stock turbo on the set up cams are not worth it cams move your power band and stock turbo falls on its face after 6k so cams not worth it on a stock turbo.

If you dead set on cams on stock turbo and no plans to go bigger turbo at all I say s1 cams

 

I plan on building my motor before upgrading my turbo. Don't plan on staying with the stock turbo forever. Basically my question is if stage 3's would be overkill for say a gtx3582r/76r

 

Why ask if you are just going to argue the points made? In building a couple Evos and other cars like you say you have, I'm sure you know that springs and retainers are a good idea with any aftermarket cam. I understand they are not the same job but if you aren't worried about labor because you know how to do it, why not do the springs and retainers? Not that much extra for peace of mind. If you are worried about it being your dd then just keep it stock. The more you do the less reliable and reasonable it gets.

 

So its been some time. Did you get around to installing the cams, if so how do you like them? I was going to go with the BC 272 w.springs for my kit im working on that will be a FBO ETS w.Tomei CBE and the GTX3576r. The 272 will be perfect for that turbo to answer an earlier question even though its a bit old. I heard some bad reviews though for the BC cams and that Kels are easier and better. I just dont like their B kit with 270/260 and then their C has 278/272, They need to make a middle B.2 kit with 270/272.

 

For 750whp would you choose tmp cams or GSC S2? Fully built everything... Beehive springs, Titanium Retainers 1mm over
