I have a 1992 Se-R and I was wondering if someone could tell me how Titanium Valve Springs could change my life? What benefits could I get from them? For that matter does anybody make them for my car?

Lighter valve train components raise the natural harmonic frequency which reduces valve float.
JWT has them. They run about $550 and by themselves are worth about 2 hp.
They are also illegal in IT if you think you still may be interested in racing there.

There are Ti spring retainers.

DOH!! I knew that. I meant retainers. Thanks Mike. Brain fart.

with the Ti retainers, you could also get some upgraded valve springs. If you are running a turbo motor springs would allow you to rev higher and make more use of the turbo power at high rpm.
though you would probable have to do the whole valve train.....
engines reving to 9000rpm is a beautiful thing
i know in the spec, among other engines, that hp goes down when nearing the very top end of the rev range. Would more effective valvetrain component move that drop to say your mention of 9000rpm? just curious. If the injectors could keep up, whats holding it back at 6grand for example.
I dont know what you mean about holding it back at six grand. On some N/A engines that have been converted to turbo ( ie KA24DE) , the turbo is capable of producing additional power beyond the stock redline. In such a case installing an upgraded valvetrain and thus raising the redline can make use of that power that would otherwise go unused when you bounce off the redline. Hope that clears things up.

so in that situation for example, lets say for arguments sake i wanted to hit 15,000rpm. Which stock components would need to be replaced, in order, from 6,000rpm and up. I hope that made sense im jsut curious to what holds it back.
From the top of my head...
Valve springs, retainers, valves, destroke the engine massively, get much lighter pistons, superb bearings, the best oil in the world, and $$$$$$$$$$$$$$$$$$
im jsut curious to what holds it back.
