So, I'm almost finished with re-hosing my rats nest. i was able to salvage all of the solenoids on it, except one. I've got an e-mail sent to Ray at Malloy to get a price on a new stock one, I figured it would be the easiest, since I'm not changing anything else.

But are there any other replacements out there that are a simple plug-and-play type replacement?

 

IMO, I would just use stock replacements. However:

If it's boost you're concerned about, I'd change the 2 turbo control solenoids, the charge control solenoid, and charge relief solenoid. New from Mazda. If you're running at all above 10psi, also install a pressure regulator on the pressure tank. That should keep you free of solenoid trouble for another 100k.

And change the check valves if you haven't got new ones handy.

 

Thanks for the info, guys. As far as the check valves go. . .I should be able to get those from any auto parts store, right? I don't necessarily need the Mazda valves? Any check valve of the same diameter should work. . . and they're sold at places like discount or advance??

I'm the check valve guy . PM'd you with more info.

Thanks for the PM Dale. . .I'm placing my order right after I finish writing this post. Also had a good time surfing around your site. I'll definitely do the fuel pump rewire while the car is apart. Good info!

 

What type of Pressure Regulator and which hose to install it on?

Thanks,
Jeremy

 

The best replacement is to use the 96+ soolenoids that came with the famous black box.They work flawlessly at 18 psi.The catch is that the connectors are slightly different,they need modification.

 

Anybody know of a cheap pressure regulator that can be used on the pressure chamber? Also I want a vacuum regulator to only allow -13 psi and no more to my BOV?

I'm not sure about regulating pressure so any help i could get would be greatly appreciated.

In my opinion this is the best solenoid replacement

 

No such thing as negative psi bud.

 

WHAT'S THE NOTATION inHg? Whatever it equates to the same thing. It's a vacuum and the math works out to the same thing.

 

You don't need to limit the vacuum side of the system; it is, in effect, self-limiting. The max you can typically generate with an engine will be about -16 to -18 in. of hg (inches of mercury) which is about -8psi.

 

yeah the problem I'm having is that my GReddy BOV is open at idle. I can't adjust the screw enough to get it to close at idle. It opens at -13 of hg. My idle is pulling -17. When I'm idling the valve is open, when I blip the throttle, it closes.

I was thinking that I could limit the vacuum in the line and keep it closed at idle.

The thing I'm really worried about is the 15+ psi I'm running prematurely wearing out my solenoids. They're brand new and I'd like them to last a while.

Has anybody used a pressure regulator that they like on their pressure tank?

Thanks,
Jeremy

 

searched around. wth is a pressure regulator gonna do to the pressure tank?

 

The turbo control solenoid on the pressure side will stick if it's subjected to too much pressure. Most will stick around 12-15psi. As you can tell, that's not good for people running above stock boost. The simple answer is to put a very small regulator on the pressure tank to keep the solenoid line pressure at 8-10psi.

wheres a good place to find a pressure regulator?

 

Not to thread hijack, but did you use the email add. for ray thats in the FAQ? I emailed him last week with that address, and I havent gotten a response yet....

 

It is, but Ray doesn't really correspond that way. You need to call him on the phone. If he already has your info, he can/will take orders that way but its best to call him on the phone.

 

I figured as much. I guess I will try to give him a call later this week.

Anyone know what hours he keeps there?



*edit* Sorry again for the thread hijack!!
