I know that some of you on this forum have switched to non-seq. My question is how does it perform and how hard is it to do? I don't drag race my car but I drive it at track events. Is non-seq better for this or is it best to stay stock.

depends, you will have to pull the turbos off the car as well as the lower/upper intake manifolds and the exhuast manifold.



You'll have to buy some block off plates, and get rid of a bunch of vacuum lines. There is a complete write up on the mod on Scud's site, if you need the link, i'll post it..

there is another way to do it that is much easier. I'm not saying how well it works, but here is the link on how to...

Lost Time

The easier way on Rikki's site takes about an hour to do and is realitively simple. You won't gain much in doing it the complete way and it will not be easily returned to sequential. Whether you'll like it, is entirely dependent upon your driving style. For most, the sequential system will probably be the most user-friendly and preferred.

The upside to nonsequential is you will have no more boost spikes and boost creep is basically eliminated also. The poormans nonsequential doesn't take much longer than 30 min or so. 1 hour tops. The longer route can have some small benifits but you have to cut out the wastegate flapper then you can't go back to stock with out replacing the exhaust manifold.You can also take out about 80% of the vacum hoses in the system and most of the solinoids aswell. So obviously tracking down vacum leaks gets way easier. Also it cleans up the engine bay quite a bit.



The downside is you get some lag. I have driven Ryans car often enough and the lag is minimal in my opinion. The car will also be a little bit louder but thats always goo IMO.





It's up to you, I like both. Sequential is money but the non sequential is nice also.

I have been non-seq for about 3 months now and I like it. turbo does not start coming on untill 3500 and full boost at 4k but when it comes on it throws you back. I can do the mod now in 40 min tops. I have done it 3 times now. its cake.

The WORKING sequential system is definitely money. However, if you've done everything to your 7 and are starting to experience either boost creep or boost spike transition, then I would suggest going non-sequential.



I like it ALOT. Makes trouble shooting a breeze and my engine bay is cleaner now :bigok:

r_xplicit

yeah, it's 'money' to put it in someone else's words......



i like it, i have however, not figured out why i am only getting 6-7 psi of boost since the nest removal though....



any ideas....i think that it might be intake air related...

I just bought my car and it had been changed to non-sequential. I don't plan to go back 'cause I'm missing lots of stuff (I'm not sure what) and the lag time isn't too bad.

BUT - there are a bunch of solinoids doing nothing and just sitting under the intake manifold, and it looks like ****. Can I get rid of these?

Practically you can rip everything out, i'll post a picture of my engine bay soon, so that you can see the simplistic nature of non-seq
