Performance Valve Springs

[Piggaz]

Buy them. Job done.

Don't muck around with jap junk. A flaccid dick would push a valve down harder than one of those "jap springs".

Thats interesting - cause i was looking at a set of the Tomei type A for rb25. So no good then?

[Piggaz]

With a jap cam, prob would be fine. Their ramp rates are mild.

Custom agro cam, no good.

Or if the valve seats have been cut they don't work either

[AngryRB]

I was told by the engine builder/shop that reconditioned my neo head to use performance valve springs at a minimum with new retainers, said he's rebuild some engines cause the retainer cracked..

For everyone. Supertech don't do a spring for the neo.

Only way to use supertech valve springs is to change valves as well. Straight from Jim at the only supplier in Australia.

Been using Tomei A springs with 270/10.8 procams for 10 years around 400awkw 25psi zero problems.

Ive had performance springs fail once in an engine. SBF at 9300rpm. Thats about it. I personally run them in my tractor with 40psi and havnt had a drama. Its like every other item on the market. If wrongly installed or abused, failure is imminent

LOL. I hear you. Just like all the posts saying not to use Tomei/HKS/Jap when none offer NEO springs either

I am going Perforance Valve springs and retainers simply because I am hoping they aren't any worse than new std OE NEO RB25DET springs.

If I could afford Ferrea (Part no. S10078 dual springs and require their Ti retainers to be used) I would hand over the cash, but given my engine is only running small 252 Tomei cams the main reason for wanting springs is boost is expected to be up around 26-28psi and revs around 8,800-9,000rpm and guess std springs may not be the greatest at those revs, boost and expected power at that level

Been watching this thread. Been using stock neo springs in mates car, 260 ponnies, 32psi and no issue atm

but building a 25/30 so was just going to get the performance spring and retainer set .

Not sure what everyone is going on about in this thread but, i have only ever seen the performance springs and double ferreas for sale for neo's.

Ive used the preformance springs in sohc rb30s with no problems

cheers

I'm only going to be running 22psi with a gtx3582r.

Interesting.

[iruvyouskyrine]

Posting to follow. Running 25/30 Neo and wanting to push 25+ psi through with a Hypergear SS2 on a completely standard Neo head.

Well spoken with the manufacturer of performance springs direct. Has Never had bad feed back about the springs and told me they even supply to some top end car manufacturers.

I think I will give them a go

[jet_r31]

Spoke with them this arvo. They where spinning their engine ove 8500 rpm.

So with that turbo those revs they kind of speek for themselves.
