Looking for a quick answer to the best set-up of a EBC on my s362sxe install. The s362-sxe kit is the dual set-up wastegate kit from Turbosource.

I am setting the car up with a Mac Valve and 12lb spring rates on the external wastegates. My setup is a 3.5" exhaust manifold to a Mid-pipe etc,,,

Question is I have seen several connection methods and I want to do this once and only once.

Can any one speak to the difference in connection methods below. I have seen option 2,2 utilized on the forums. But never option 2.3.

1. Please let me know what's recommended and why?
2. ​I am assuming method 2.3 has no fail-safe in the event of valve failure?
3. Also would it make a difference if I used the MAC valve or an older Greddy Valve?

I am looking to set high boost at no more than 16 lbs.





Thanks

Since noone had answered i will start with asking, What EBC are you going to be using? I have Greddy versiin 2.
2.2 is the way it works for me. I have not seen the 2.3
1) Allows you to increase boost pass the spring presure in the waste gate for almost double. Other 4 ports had been said to increase even more, i am not sure on that one though.
Depending on the Boost controller it will limit boost in a overboosting situation.
It allows you to control boost sooner. You can make boost sooner in the rpms.

2) never seen it.

3) 3 port solenoid is good. I have seen a lot of plepole using them.

 

Appreciated. I am using the Greddy Type-S ebc.

 

The 2.3 method is described in the Turbosmart GenV wastegate manual.

I just hadn’t seen anyone using this setup.

 

Do the Tial gates operate differently than the Turbosmart units? I run the EFR 3 port solenoid with dual Tial gates in a different set up. One port on the solenoid to atmospheric, the other is mated to the turbo, and the other line is T'd to one port on each wastegate while the second wastegate hole is vented to the atmosphere. Seems to work really well for me with my Haltech.

 

They work the same way. The bottom goes to the presure/turbo and the top to the boost controller.
I think it depends on the solenoid to what port where is to be connected to.
The boost controller is going to hold the wastegate close to give you more boost using the top port on the wastegate.
Just to give an example..:
Here is how Greddy external wastegate are connected per their manual.

 

Interesting so I am assuming no one is using the 2.3 method above?

 

The 2.2 method is typically the way it's done with a 3 port solenoid. It generally gives good control and allows for about double the spring pressure. Also if you want, you can put a switch on the power side and turn the solenoid off to just run spring pressure. Kind of a "valet mode" if you will.
I can't say I've ever seen the 2.3 version. Hopefully someone will be able to enlighten us on this approach.

 

After some diging, I found this old thread.
https://www.rx7club.com/single-turbo...-21psi-862100/
Arghx shared good insite to the 2.3 set up.

 

I wouldn't do the 2.3 unless you're trying to run a lot of boost with a weak spring, which is kind of a turbo 4 banger thing.

 

Just to clarify, I have been successfully using the 2.2 method. The 2.3 method was suggested to me but I was hesitant because I had not seen that method on any forum write ups. Besides I will be running limited boost at 16 lbs max.

 

Thanks for bringing that post back up. I read through it before but missed post #12 references from arghx.

 

Got it! Btw thanks on those related write-ups.
