Performance Valve Springs

[RamblinDMC]

Does anyone know where I can get performance valve springs? I'm looking for stiffer valve springs similar to the type used on the Alpine A610

Thanks!

Why? If you are trying to do it to reduce valve float, it is not a problem unless you are trying to increase the redline but you will have bigger problems than valve float. Stiffer springs will also cause more cam wear. If you are running a very "aggressive" cam you might want stiffer springs but then you should consider rollers not tappets. Hard to improve the PRV without doing a whole lot to it. It is a very well balanced and engineered motor in stock form. You will find it difficult to get a lot of aftermarket performance parts in the US for it. A big reason most who want more performance will just do an engine swap. A really good engine rebuilder may be able to match up some springs from some other motor that could fit.

I'm getting rid of KJet in favor of a Porsche Style ITB setup. I will be running a more aggressive cam. However I'm not aware of rollers for PRV valvetrains.

Once my build has a bit more progress, I'll be making a thread about it here. It's something that's never been done to a PRV in a DeLorean before.

Thanks!
