He has an Evo lV though. Do those other manufacturers have cams for his car?

tzoyi

thank you for the answers,my tuner said me to buy 272 cams but i dont know,which is better? are the 280 little laggy?

They both have the same lift. As for lag, you won't be able to feel the difference if there is any.

I had 272's had and now 280's, no difference in lag.

tzoyi

thank you,what different did you see when you change your cams and which is better?

What ever you decide to do please buy a cam that will actually give you a good power band and not 20 hp over stock. Idk much about the hks 280s but if there like the 272s there a joke. I would buy GSC cams or Kelfords.

^Agreed, but he has a evo lV (4).

tzoyi, I can't really give you any difference as in numbers, as I never dynoed my car when I had the 272's.

I made 373whp with the hks 280's.
Stock block, stock head, stock IM/ tb, stock fmic, stock licp. lX turbo
Injen Intake, uicp, 3" Full tbe, fic 1250 inj. 92 oct. 24psi

And 444whp with the above parts + fp black and tubular ex mani, o2 dump.
92 oct. 29psi.

Both with conservative tunes.

I think You should have no problems with the 280's making decent power with the mods you have already. You have better parts than I do. LOL

ok,thank you for the help,i will think it because i am about gsc s2 and hks 280..

Cool, If I were to do it all over I would probably go with the gsc s2. It's just that with the 280's I didn't have to change springs. But you have a built head and if they make the gsc s2 for your engine, that would be your best choice.
Good luck

HLS 264/272/280 is old design
GSC S2,Kelfrod,HKS 274/278,Tomei,JUN etc all outperform HKS 264/272/280
