i've seen a few people on the board saying they've ran hks 280's on a stock valvetrain shifting at the stock redline and nothing bad happening. i have the opertunity to get a set of revolver 280's from a friend minus the springs and retainers is it ok to put them on the car with out the springs and retians as long as i shift at stock redline? any answers are greatly appreciated.

 

bump.....

 

i think you should get some supertech , since you have the cams out ....

 

are you sure they are revolver 280s???? i dont think revolver ever made 280s

i have the 262-264 revolvers....

 

No way at all. HKS 280s have 10.8mm lift on the intake side and 10.2mm lift on the exhaust side. The revolvers have 11.4 or 11.5 on both the intake and exhaust sides. I wouldn't even let the car idle with Revolvers on stock springs and retainers.

 

you are right sir. thanks for pointing out my mistake. they are 262-264 cams. are they safe to install without the springs and retainers?

 

anyone?

 

bump

 

dont even try to run these cams with the stock springs you will have a blown motor before you know it.

Upgraded valve springs required

 

thanks for the info so what springs should i look at? and how much should i expect to pay to get them installed?

 

well if you dont want the revolver you can run hks 272's on stock springs, BR makes some you can run on stock springs, GSC s1's can have stock springs. You can look it up and see which ones require new springs. Also take into fact about how much you want to build up your car. Install is a few hours. I think like 2 or 3 i have been told.

 

Revolver sells their springs with the cams as a complete package. Realistically, you should be looking at theirs as they are made specifically for their cams. Noramlly, the whole package goes for $770 shipped. I'd contact them for purchasing info for the springs and retainers.

 

its is not the durations ie that make the 280s not able to run on stock valve train its the lift. hks cams for evos suck. there isnt enough lift. and yest with revolver 280s YOU HAVE TO run uprgraded springs

 

iirc you don't want to run the revolver springs and retainers. there was an issue with the springs.

you do need upgraded springs and retainers.

 

Revolver isn't even in business and hasn't been for some time. Not to mention the QC issues with those springs anyway. Even the cams have QC issues.


OP, the inexpensive option would be the supertech dual kit.
