What are ideal springs and retainers for a turbo setup? I've searched and all I can find are the super tech ones on EBay and 949racing.com are they any good?

 

What redline?

 

They offer a dual valve setup that allows you to rev up to 9k

 

Wow. You can read the brochure.

I feel like a few more mods other then those valve springs enable a safe 9k redline.

 

Like an ECU? OP's sig states he's on stock ECU..

 

Well, I know my setup was able to spin to 10.3K without float, but that was tested due to user/revlimit error, will hopefully never happen again.

Springs is part of the valvetrain, which never should be handled as a complete system.
Cheap Ti retainers, no thanks (my custom steels one were not cheap though...)

 

Not on stock ecu anymore I gotta update that lol

 

So no one is running super tech springs? Is anyone on built head at all? Super tech also has 1 mm bigger valves coated in black nitride that seem to be alright. Does anyone have any experience with these items?

 

Holy Hell

 

Right?

Could we possibly be provided with less information to digest in order to better guide OP?

I think not.

 

Nope. Nobody here is running any form of "built" head. Those +1 mm valves sound cool....that must be a brand new product that just hit the market. No.....wait.....I just did a 10 second search and found out they have been on the market about 10 years.


Kids these days.


Reading is fundamental.

 

As much as I would love to sell you a wicked built head that flows 25%+ more than your current head and will rev ~1500rpm higher, it's not a good place to spend money until you've got a built bottom end and a good tubular manifold to match it. Headwork is fruit from the very top of the performance/cost tree.

 

I have a built bottom end, all I'm asking is if people use super tech if not what are they using to build their heads?

 

Still not the necessary information. How much boost? What turbo? Power? Desired RPM?

 

Right now I have a small eBay t3 turbo with 1000cc injectors and walbro fuel pump and a mild tune on emanate ultimate making 220 at 10lbs of boost, but eventually I want a bigger setup and I want the motor to handle 300-400 HP on a full tune

 

That's cool.

So what is this thread about?

 

Valve spring, retainers, honda like redlines.

 

Putting CTR springs in my GSR head with ITR cams let me spin to 9200rpms. It was awesome.

 

Aw man you have my supertech springs in my vvt head with stock cams beat by 700 rpms.
