Should I Be Replacing Valve Springs?

Featured Replies

As the topic states, I haven't driven my GTR in nearly 8 months - flywheel issues, but that's another story.

What's the opinion on the standard valve springs? Will they be an issue seeings as some of them have been compressed for so long? eg. Possibility of valve float at high RPM.

Fresh motor (3000kms) but std. springs.

You should have no dramas as they won't be byond their elastic limit.

What RPM are you planning?

Not sure what Ben's set the limiter at, but when I stuffed the flywheel, it spun around to 8500rpm, before I could get onto the clutch. I spin it to around 7500rpm when I'm on the gas.

Stock cams...?

If yes, I doubt there'd be an issue.

They work OK even with larger Poncams.

Just ask Ben, very few people seem to know more about these things than him. :cool:
