Valve Springs?

[16secGA]

Does anyone know if someone makes custom aftermarket Valve springs? Preferrably Titanium. I'm going to add N20 to my car and a Turbo further along down the road. I would like to upgrade my Springs in at the same time I add the NOS and then again when I rebuild and add the turbo.
Thanks

I know it sounds funny but JcWhiney is starting to carry sport compact parts. Im pretty sure i saw valve springs in there for sport compact.

Yea but not for Grand Am's those guys are getting into the import scene also! Or is it pretty much the same on a four cylinder regardless if its Honduh, Pontiac, Chevy, Toyota as long as its a four with dohc would they fit?

[wileys_farm]

No it wont fit. Different models of import and american cars valve spings wont swap over. The valve springs have a certian height, tension, and circumfrance of your vehicle usually different than another make/model. You could get lucky by finding the same thing but its a long shot. Have you checked the dealer for your valve springs?

Yea but
1) They will be way overpriced
2) they are stock springs and not performance

I am adding a 50 shot of nos and I don't really want stock springs unless its theres no aftermarket springs whatsoever. Thanks for the help. I want to see if the Nissan SR20DE springs are the same. The nissan motor is similar to mine. Same liter displacement and same HP.

Another idea to try is your local machine shop. Around here the machine shop orders high performance springs for heads on request. They might be able to get you some or even tell you who to check with.

Is this a joke?

Titanium valve springs?

If I had your money, I'd burn mine!

Titanium valve springs are WAAYYY overkill for that engine!

There's no reason to go to titanium valve springs unless you're turning that engine CONSISTENTLY over 10,000 and making over 1000 horsepower. That's basically Pro Stock drag racing (and faster) stuff. And the price will not only knock your socks off but will strangle you with them.

Check out Manley or K-Motion (or any camshaft manufacturer like Crane, Comp Cams, Lunati) for an excellent selection of valve springs. Their catalogues list them by inside diameter, outside diameter, free height, seat pressure at installed height and coil bind height. I guarantee you'll find a decent double spring that will more than accommodate whatever you've thrown at that engine.

Besides, if you're not running into valve float, you don't need a stronger spring -- you're just wasting energy and money.

Side note: the reason most valve springs fail is they are overheated. Ceramic coated springs (again available from cam manufacturers, Manley and K-Motion) will last indefinitely. If those are too pricey, fabricate an under-valve-cover oiling system to assist them.

The circle track guys run this type of valve cover to let their steel springs last 500 miles at 8000 rpm. Comp Cams makes them for small and big block Chevrolets, so you can look at them and get some ideas for your own.

I got my springs from Jegs and they rate at 10,000 rpm and they are not titanium. If you do go with the super duty springs you will have to put bigger keepers,hardend valves, and probably a cam that can take the extra load.

Whoa, really? So thats what Titanium is for Pro Mod? Then why the Fizuck do so many Sport Compact companies make them for the new Gen cars? Um besides the Engine has 96K on it and A 50 shot of NOS may Kill the Valve springs. And that is on the bottom of my to do list.

the springs are problably already dead. A fresh set will liven up the performance of any engine....

Something else I already knew.
