I would agree that if they are in good shape that is a pretty good price. The HKS 280's do not require upgrading the valvetrain according to HKS, but they def. are more aggressive than the BC280's....so the valvetrain upgrade is your call, for the price your paying for the cams might as well throw the springs and retainers in and be done.

The car will idle lopey and there will be no denying you have cams with the HKS280's.....It seems they work well on stock turbo cars, do a search for "HKS 280" and start reading

I'm saying Crower says to put springs and retainers in for 280's...if the HKS is more aggressive, I would not feel good about putting HKS in without doing the same.

 

do you go to the bally's by shv mall? what time do you go, i've seen a guy with a white RS VIII there, but never anything else.

 

Yes I go there I've yet to bring my evo there though. I'm driving the silver eclipse till I sell it and keeping my evo in the garage. My friend steve has a silver VIII there. Maybe thats the one you've seen. I go monday wednesday friday at 315 and tuesday thursday at 930am.

 

Well Ty, seeing as i am in FL right now i am unable to go. I can't wait to come back and tear it up though.

Thoughts on me buying a Motorcycle guys?


Steve

 

With all the cam talk, how about the GSC S2's for a larger turbo?

On a side note, I broke down and bought a set of BS RE-O1R's Got a pretty good deal too.

The Dunlop Direzza's are on backorder until May. That's what the Goodyear rep told us today.

Does anyone in Pittsburgh have a road force balancer?

 

Pretty sure Day Audi in monroeville has one!

 

Really? That's good to know. I never even thought about it till I was talkin with a coworker today. I've had such problems with balancing in the past.

 

GSC S2's are recommended for big turbos

 

Thanks Travis... lol Read my quote, lol.

 

Well now that I have read it 15 times trying to figure it out - I see you were questioning the recommendation of using them, not if they can actually be used.

Sorry - miss interpreted that, downfall of communication through reading/writing

 

Yeah man hope you're having a good time down there. Hopefully by the time you get back the weather will be a little nicer. What kinda motorcycle you looking at? Personally I like the Honda CBRs the best.

 

can I use BC springs and retainers with the hks cams?

 

I would consider, going with the Buschur Racing Supertech Dual Valvespring , Titanium Retainer set.

This will allow you to upgrade to any cam you could dream of running , and has 10k+ rev potential

 

Is this for an VIII or IX?
