i have a 2001 honda prelude base.... I bent all my valves... so now I have to get all new valves... is it worth getting performance valves on a completely stock motor? or should I just go ahead and get oem honda valves? will my car have any noticeable performance gains if i put performance valves in it, for example manly or skunk2, when the rest of the motor is completely stock? and if i get performance valves... should i get all performance valvetrain? what are the pros and cons of this situation? i would really appreciate some advice... my car is sitting at honda right now... and they wont warranty it... so i have to get my car out of there real soon... so i gotta make up my mind what i wanna do with it... thanks alot in advance guys

 

by the way.... what is the best type of performance valve that i can get for my money??

 

anybody? i need help guys

 

We aren't all on all the time.

On a stock motor, you won't see much of a difference. If you plan on upgrading the head later (or now), I would consider aftermarket valves, since you have to replace them anyway Aftermarket will probably be about the same price as OEM anyway.

Performance valves are lighter and stronger, and typically nitrided to reduce friction.

Be aware, chances are your Honda dealership will not install aftermarket parts.

 

Aftermarket valves that are lighter and stronger than stock will help you out, but you're not going to feel much performance from them. Lightening valvetrain components allows them to redline higher before. To a degree Basically, its less mass that your spring has to compensate for. There's some flow pattern differences too, but its nothing terribly noticable in a stock head. Like qtiger said, you'll see more benefits when and if you do headwork. While you have the valves out is also a good time to upgrade the retainers and springs if you've got the cash.:thumbup:

 

You will also need stainless valves for high compression motors, and those running high cylinder temps thanks too lots of boost or nitrous.

 

someone was telling me that upgrading valve springs on a stock motor is not worth it cuz the springs are stiffer and they are putting more stress on the motor because it isnt worked up at all... i dont know if that is true... and also... what kind of performance valves and springs/retainers do u recommend to be the best bang for the buck?? thanks

 

Crowers. :thumbup: You've got the benefit of having a big company support them too. The Eibach valvesprings are schweet, but not worth the 500 dollar price tag unless you're running a superhigh lift cam.

 

I'm going to be running Skunk2s soon, but the only real reason I picked their springs is because I'm going to use their cams. :dunno: Figure might as well.

Springs and retainers are pretty much universally fine as long as they are a decent name. Skunk2, Crower, Portflow, Toda, Jun, Spoon, etc, etc, etc.

 

If I end up replacing mine while I've got my head apart, it'll be for the same reason. I'm still crossing my fingers that Crower will start making roller cams and use their needlebearings in followers in addition to their rockerarms. :thumbup: If not, I've got a pair of 411T's calling my name.
