Ok I went to the Mazda dealership today in search of the wastegate solenoid just to price it to see if I wanted to purchase it. What I found out was that for one: you just don't ask them to look up the "wastegate solenoid", you have to look at over 400 not so precise diagrams.(j/k) The second thing that I found was that when we did find one with a part number on it, they told me that I had to buy both the turbo control and wastegate solenoid together. I didn't mind this as long as it was reasonable. (I have gotten a couple things as bargin basement prices from the dealership because I know a couple of the guys) So once we found it they got me a price and it ended up being $175 for the two and I was floored, but should have expected as much.

This leads me to ask where can you get any solenoids for our car cheaper? I mean everybody is going to have it to deal with because our cars are almost 10 years old.

By the way if you need a part number on anything in the intake, turbo, or rats nest and most of the actuators and solenoids I have them because he let me keep all the little diagrams we printed off.

You probably already know this, but you can find them used here very often. All the single turbo guys often have these available.

I plan to post pics of how to repair the solenoids. Typically you just break the nipples off which leaves the solenoid functional but unusable since you can no longer connect the hoses. I have very carefully cut the nipples off flush and then opened the holes up slightly with a drill bit. You must be very careful not to drill too deeply or you will ruin the seat inside the valve. With the holes opened up I epoxied short lengths of aluminum tubing to create new "nipples". These work perfectly and if your solenoid is already broken, you have nothing to lose.

I suppose you could just stuff tubing inside the hole without enlarging it, but this leaves a smaller inside diameter than stock and I was concerned that this may effect operation.

What type of epoxy did you use? 5 minute, 30 minute, metal, etc? I used a 30 minutes epoxy on the nipples before and they still work great. I thought I used the same epoxy on my air box and it just cooked and ended up cracking (time for an aftermarket intake).

I think I'll get some of that epoxy they use on engine blocks for the next nipple problem. That stuff sticks!!!

You can buy them brand new for $99 delivered - or you used to be able to. Check with Malloy Mazda or Mazdaformance.com

If you race you can get them at lower cost through Mazda Comp.

And I can sell you a nice used set (tested to spec) for $50. ;-)

Never heard of anyone using aftermarket. Not to say it can't be done.

I'm doing the non-seq. job myself, and broke two solenoids. You just may be getting a PM

Just let me know what you need I have all the numbers right at my fingertips. Or at least in my RX7 folder that has all the work I have had done to my car in it. Man that thing is getting thick. I might have to move over to a filing cabinet to keep all the papers in. Let me know.

My solenoids do click but according to the manual I should be able to blow air through the air pipes when I connect 12V to the solenoid. I can't get any air through either the wastegate control or the pre-turbo control or whatever the 2nd solenoid is called. Is this likely do be me doing something wrong or are they both bad? It's a simple enough test so I can't really see how I could be getting it wrong.

My car definitely doesn't boost right on primary and I've noticed a lag when the secondary comes on, which is consistent with my solenoid tests I believe.

If you need some solenoids let me know I did a single conversion a few months ago and have all of my solenoids and will sell them to you cheap.

Peter Paul Solenoid Valves in New Britain, Connecticut makes stainless-steel valves with viton seals. I looked into them briefly, but not too seriously.

I'm sure they're not cheap, but neither are the Mazda ones...
