I am in a grind of which cams to get and what are the difference between theses cams. i was wondering if anyone could help me out and tell me how much HP they gained with one of these sets of cams. I am not looking into upgrading the valve train so that is why Ive chosen these. Thanks in advance!

 

HKS 280s. The before/after is awesome, and you could run them for 100k miles on the stock valvetrain w/o any worries.

 

thank you very much^^^^ I was leaning more towards those.

 

i was under the impression that with any 280 cam it is recomended that your upgrade the valvetrain anyway? this is great news if I am wrong. and +1 on the HKS cams I have been in a car before and after and the difference is awesome. idle sounds mean but isnt to crazy for the street. gl in w.e you decide to go with and let us know the results!

 

u shoudl really look into KELFORD 272's the best out right now for street/strip use. i am on hks 272's and im thinking of switching to those

 

I know but they are a little out of my price range. Im trying to find some used cams... I was laid off in Dec. and really dont have much cash to play with, the reason i am getting cams is because im getting my timing belt service done and it will be cheaper to throw them in while they are doing that!

 

Thanks for the INFO, depending on which cams i get ill definitely be posting up before and after!

 

my car runs fp4rs on stock valvetrain and she runs great

good power and sound

 

if u want ill sell u my hks 272's lol so i can do the kelfords lol

 

i really want 280s lol how low for the 272s

 

how much HP did you put down

 

Anyone else??

 

I would go with the FP FP4r's those are supposed to be better then HKS cams. I think the have a slightly more aggressive valve lift. But I would also suggest GSC S1's they have more aggressive valve lift like the Fp cams and you don't have to run the crazy duration. Remember duration is not the key to HP. Both are drop in cams so you should be happy with those. I'm currently running HKS 272's which are going to be swapped out for Kelford 272's in anticipation of my FP red turbo install. I think the GSC S1 would be the best choice for your needs. My buddy Petey Turbo runs them on his 05 and I know on race gas he made like 400whp. Now he is running e-85 and he is making about the same HP but 430 of tq. Can't go wrong with that.

 

I run the Comp 280's. I chose them over the HKS because they have a higher lift and more duration. In essence, they are just a more aggressive cam.

 

My research into cams has also led me to the understanding that once you move up to a 272 or higher type cam then upgraded valvetrain (springs/retainers) becomes a must. It is physically possible to run 280's with stock valvetrain, but it is not in your best interest for longterm reliability and durability of your valvetrain/head. Don't forget a failure up there that drops a valve into a piston can cost you entire motor and turbo!

It's defn smart to save up and do 272/280 with springs retainers, rather than risking a half assed shortcut that could bite you later!
