Uprated valve springs


Recommended Posts

Yeah, I'm sure you know what you're doing, but is tougher springs necessary for your application?



It's only really needed if you're intending on exceeding the stock limiter greatly. Since our engines rev high anyway....



Don't throw money into "Uprated" parts when you are not going to be using them.

What I remember or readed, was the turbo modell springs stiffer than n/a, is there any info about that? Not helping You Gainzy, but maybe some n/a guy like me...

I would need them to what I want to run as the stock one's will be too tired. We shall see.

is there head/machine work that needs to be done to support uprated valve springs?---think i've heard this in the past

Hence why I said you need the spec sheet so you can get the correct base pressure. Otherwise they could wear out the cam lobes then you end up with no surface area to push the valve down, then end up with a missfire.
