Enjuku Racing Presents: Brian Crower Valve Spring and Retainer Kits for SR20DET! - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Enjuku Racing · 07-25-2006, 10:19 AM

Brand new from Brian Crower, Inc - Valvespring and titanium retainer kits for your SR20DET.

BC's description:
"Designed for high rpm, BC valve springs are wound from only the highest grade, super clean, chrome silicone alloy and feature proprietary processing procedures for consistent pressures. BC titanium retainers are CNC machined from 6AL4V round bar titanium to exacting tolerances."

Here are the specs on them:
-Seat: 1.550" @ 90 lbs
-Open: 1.025" @ 220 lbs
-Coil Bind: 0.910"
-And of course no machine work required

As you can see, compared to the very popular Comp Cams and Ferrea valve springs, these are have a higher advertised seat and open pressure. Compare below.

-Comp's seat pressure is 75 lbs, open load is 189 lbs.
-Ferrea's seat pressure is 80lbs, open load is 195lbs.

So what does this mean in lamen's terms? Higher rpm's and less chance of deadly valve float, since everyone knows these SR valve and rocker assemblies like to party out like New Year's Eve.

These BC kits are quality, performance minded, affordable kits with excellent specs. Be the first cool kid on the block to have them and still have enough money to take you and your friend out for drinks after the install.

Do we have these things on stock? Yeppers - 20 sets good.

Pricing is as follows:
$220 shipped per set (included springs AND retainers)

Payment options:
PayPal to [email protected]
Credit Card via 407-673-1320

Please make sure to include you are from Zilvia in the notes if paying via PayPal and we'll get these shipped out ASAP. Please post or email if you have any other questions. Check out our site and look in the New Parts section or www.briancrower.com and take a look at what else they offer. We are updating the site routinely as more stuff becomes available. If you see something else you like, I can get that for you too.

Keep an eye out for upcoming specials on more BC stuff as it becomes available.

Thanks guys!

I noticed they have developped a 2.35L stroker kit for the S13 SR20DET..have any case studies or competition cars running with it?

I've had quite a bit of inquiry about the advertised springs rate of the Brian Crower spring vs. Ferrea Dual spring, i.e. how can a single spring be so close to a dual spring setup? Because of this we went ahead and did a side by side test of the two on our own time. Needless to say we were VERY surprised at the result. What you are looking at below is the rate of the spring in pounds @ different compression heights. I'll let the numbers speak for themselves.

Rate @ 1.550"
Brian Crower = 80lbs
Ferrea Dual = 90lbs

Rate @ 1.339
Brian Crower = 140lbs
Ferrea Dual = 140lbs

Rate @ 1.200
Brian Crower = 175lbs
Ferrea Dual = 175lbs

Now the importance of these numbers isn't how close these to the 'advertised' pressures, as every spring rate tester will be a little bit different. What you want to note is A-B test of diff springs on SAME tester, which is exactly what we did. Regardless, these BC springs showed us they are even better than we had initially thought. Right now we feel these are the best bang for the buck hands down.

We have 13 sets of these left.

I got mine today and will test them in the next few days... so far they look like a quality product. I can't wait to try them out. I'll even have the weights of the titanium retainers vs stock units. Should make for interesting reading.

how do we order at the special price?

Teddy,
I am looking into upgrading my S14 SR head. I would like to include these in my build, but I would like some guidance on the rest of the parts- cams, valves, etc for a drift setup.

sideview_180sx · 08-02-2006, 06:54 PM

there is no real drift setup, high rpm. that's it. road racing, drag racing, drifting, all use high rpm. this includes cams, they all help the motor breathe better, its up to you how you put it to use.

Healtoeae86 · 01-30-2007, 02:19 PM

Do you know if they make 87mm pistons in 9.0 comp for stock sr20det?

I see that they have pistons for their stroker, just banking on the chance they might make them for stock SR's. Also could you PM me a price on that and rods for a sr20det?

Thanks!

projectdrifter · 02-04-2007, 01:55 PM
