I have a question about what type of valves springs to use, with 00-01 ITR (CTR) cams. I plan to use this with a turbo setup down the road too and dont plan to do the work over. I looked around and havent found the specific to my question. I saw some guy with a set of Skunk2 valves and he has the Tuner and Pro series. I was going to get the Pro, but he said it not needed. SO I would like a second opionion....
Oh yea, what type of valves do you guys recommended too? (Also, plan to get a full port and polish and plan taking to 9k-10k RPM)

I mean there is a lot of aftermarket valve trains you could run.

The best in many people's eyes is Ferrea. But Toda also makes a great system.

You can use your stock valvetrain, if your keeping your stock redline. Other than that I would invest in springs/retainers.

 

for the price and the quality, Supertech is a great choice.

If you have read the whole post, I said....TURBO Setup. Thanks for the info though.

what the hell does a turbo set-up have to do with stock redlines and valve train? You do know what a valve train does right?

A wise man once told me that when dealing with boost- you have to consider that your boost pressure will make it harder for your intake valves to close. Running upgraded springs, even with a stock redline, is not a bad idea.

You are very correct sir, but upon reading the OP's response to his comment, it was clear he didn't know what he was talking about.

While it is smart to upgrade the valve train with any modifications really, a mild build and boost you can run safely on a stock valve train.

um... Added pressure on the backside of the valve during boost....thats all.

a 30mm valve has ~ 1.09563263 sq in of surface area

at 15lbs of boost thats taking 16.4344895lbs of pressure to hold the air back......
a 35mm valve (h22 intake) needs ~ 22.3691662lbs to hold the air back.

that extra 22lbs is taken from the seat pressure.... so you tell me if its important

 

So with all that being said, this goes back to my orginial question.....if I order a set of valve springs which would you guys recommended....I dont want to go all out with the top-end of one manufactors and knowing I could have use the lesser one for the same results. ie...Skunk2 Pro Series or Tuner

 

Ferrea, Toda...I also believe Manley and supertech make valves springs and have gotten good reviews.

When you're revving to 8000rpm, how long is your valve closed for?

 

I was seen a lot of people using Ferrea Valves, and not a many complainces either and they run pretty cheap too. But what type of valves springs, I like the Skunk2 but dont know what to choice, Pro or Tuner?

 

Ferrea makes everything you need at great quality.....get some 6000 series valves. They also make the best valve springs and TI (titanium) retainers or among the best.

 

I havent heard about their springs or retainers, I got to check that out.

 

I've used Ferrea, Skunk2 and Supertech with no issues

 

I use ferrea and they are the ish I would like to be able to afford a toda valve train lol!!

 

I am in Japan, and TODA seems to be expensive, even here. For the prices I have seen them.
