How To Go Non Seqential???
Does anyone have the HOW TO: NON SEQUENTIAL
I have done a search but...The ones that came up were insufficent...
Let me know if you have a more detailed version of the "poormans set-up" or an even better more detailed version...
Also, Im using a PFC to control boost
Thanks

2. Take the blow off valve and charge relief valve off
3. Disconnect the vacuum line to the charge relief valve and cap it at the upper manifold.
4. T into the blow off valve´s vacuum line, and run a new line to the old charge releif valve.
5. Remove all vacuum lines to the charge control valve on the rear of the Y pipe. This should dissable the butterfly in the Y... keeping it open always. Besure to cap all the removed vacuum lines to the manifold and Y pipe.
6. Jack up the car, support it with jack stands, and take off the front passenger side tire (this makes it tons easier to get under and out of the car.)
7. Remove the head sheilding to the under neath of the turbo (should be 5-6 10mm nuts and bolts)
8. Remove the keeper pin from the actuator rod and seperate the rod from the door mechanism. Wire the door open. I ran a wire around the actuator around the door lever and back about 3 times. (tip: with the car off, the door is closed. to open it, it should be rotated towards the front of the car)
9. Remove the vacuum lines to the Turbo Pre Control actuator, remove the rod to the door, and wire it open. Make sure to cap all loose lines.
10. Leave the direct pressure line (the one with the restrictor) on the Wastegate actuator.
11. Resinstall all your intake hoses, make sure it is all tightened, and take it for a spin around the block

Is there a big diference between non sequential an stock. I'm just wondering if its worth it. I may begoing single turbo in the future. What kind of power gains can I expect w/ non sequential stock twins?

I think this is what you are looking for:

Someone suggested this to me in order to fix my boost problem I'm having with my car. I haven't had the time to do the actual conversion, but I plan to do it at some point.

The power with non-sequential is felt in the midrange 4K-6K rpms. You have around 25-30 more hp in that "powerband" since both turbos are spooling. High end power is the same and low end power is not as responsive as with sequentials set-up. Overall, it acts like a small single turbo getting full boost by 4K rpms. Very smooth power all the way to redline. If you like the very low power and the "kick in the pants" of the second turbo at 4500 rpms then stay sequential. If you want a hassle free turbo system with smooth predictable power then non-sequential is for you. Overall, the power is a tradeoff of midrange and lower but if you are racing - I'd say non-sequential is better but getting around town and auto-crossing the sequential system is better.

Has anyone tried this does it work? I have been thinking of going non seqential. But most of what I read is saying that you have to take the turbos off cut the flap out. I am going to go single over the winter I hope so I do not feel like pulling the turbos of now.. What you guys think is the best way.

If you're going single in the winter, I'd say leave it seq for now, you've only got a few months. But if you want a taste of single now, it only takes about an hour for an inexperienced person (i.e., me) to do the non-seq.
To any and all who attempt: beware! I did this on the stock ECU, and according to Dave at KDR it was what blew my motor. He said my engine may have been on its last legs anyway, but here was his diagnosis. The ECU expects a dip in boost to 8 psi at 4500 rpm, and cuts back fuel to acount for it. In non-seq mode, there is no dip, but the ECU still supplies less fuel, so it runs lean. He said that was more than likely what blew my motor. The Power FC will do the same unless tuned.
I'm not saying your motor will blow, because many people have successfully run non-seq on the stock ECU. But mine did, within a week after I performed the conversion. Just be careful

Thank you for the input 911gt2 I will keep that in mind.
The real reason I am thinking of doing the conversion is Iam in the process of getting a new ecu most likely the new haltech e6x which to my understanding will not control the stock seq setup...

Ryan was shown this modification by 7sins. Ryan showed it to me and on down the ladder this one goes.
I know that one of the PFS customers has Ryans/Danny's site all fucked up so I don't think that he has that how to anymore.
The link above is geared more towards the full non sequential conversion as opposed to the jerry-rigged way. If you have the twins non sequential is the way to go if you work on your car alot. Simplifies the system so much even I actually rember where all my lines go.
