HD valve springs.

EDXR6T · 09-04-2007, 06:42 PM

Hi all

Just wondering what a good set of HD valve springs is going to set me back for a AU 6?

And where would be the best place to get them, will Repco or Burson be able to get them for me.

Any help would be appreciated.

Cheers.

Go with the springs your cam grinder recomends! Crow would be a good start for cams and springs.

the springs i have are used on saloon cars and will run anycam you can throw at em, they are double springs straight shaped not conical like standard ones. A forum member supplied them for me.

i might be wrong, but if you want the stiffest crow springs you have to do some modification to the head for them to fit. (what i have been told). not that i am a fan of JMM, but they supposedly have some good AU valve springs... something i might be looking into soon

yeah my head has been fully done, theres something different on my head as well my valves needed machining to fit the valve springs im sure, i just got a Vernier gear yet to fit it i got it for 160.

What exactly need's to be machined on the valves??

Plus where did you buy your Vernier gear from joe?

I would prefere not to get a set of spring that JJM have there name on as I recon there price would be exploded to somthing I wouldent pay.

Il give them a call and see what they can let a set go for.

i think the tops of the valves where machined down a little, i think they were around the $175 mark but its fitting which costs hundreds cos its all labour. I got my vernier of a foum member also.
See you'll ring JMM and they come up with a different theory on their product and why its so good bla bla etc

The JMM springs are 30 buks each by there website which equalls $360 for the set of 12 lol, then you problly need there Au retainers which are $135 so your looking at 5hundgy already, plus 300 for fitment plus vernier 180 your looking at close to a 1000 buks

: Yer screw that...:P

Would E-series spring and retainers work?

As long as the diamiter of inside the retainer fit's over the AU valve's and alowes room for the collets to sit in properly I cant see why they wouldent work.

I havent messured it up but AU springs and E-series look about the same size length wize not sure about depth tho the AU's look a little bit smaller at the widest point.

I might have a crack at it tomorrow and see if it wont work, it will be a quike fix till I can find some AU HD springs that are suited to the cam's specs.

All the work wIll be doing by me, so I dont have to worry about laboure.

OED666 · 09-04-2007, 10:38 PM

i already have a vernier wheel... and fitment can go jump. ummm, retainers... i'll check that out...

JoesAu · 09-04-2007, 10:47 PM

What cam is it?? how much lift?? the au springs are stronger and more firmer than Eseries. Ring Crow tommorow you'll have em the next day or that day if u pik up for under 200
