a speed shop in panama city just opened and i stopped to check it out. I talked to the owner and he suggested that i let him rework my vacuum hoses . no big deal right !!! Well he wants to eliminate 75% of the vacuum hoses and all of the solenoids and run the car on both turbos all the time . I need the vacuum hoses done but im not sure on that kind of modification .Have any of you ever heard of doing such a thing ? Ive had 5 of these 3rd gens over the past 9 years and ive never heard of that kind of work being done to anyones car . Let me know what you think. thanks greg

 

Ummm..... I think what you're talking about is the non-seq converstion. There are a ton of posts about it here. Check 'em out. Tom

 

yep

 

well he could be talking about the turbo simplification, i did that and then only had 28 hose left and a total of 4 solenoids and no more rack, but i still ran with it seq setup.

 

How does that simplification work out? Does it run the same? Downsides?

 

Do a search for non sequential!!! There is a ton of info out there on it.

 

But he is talking about "running both turbos all the time". Sequential means the primary comes on then the secondary comes on to assist the primary. They both run at that point in time however at the beginning it is just the primary boosting and therefore they are not both running at the same time.

 

Thanks for gettin' my back tt. That's kind of funny, as I just replied to a clutch question with a quote of yours

Tom

 

 

dude ditch the pressure regulator solenoid you dont need it

mike

 

There is a huge difference between non-sequential and the simplification of the turbos. I would stay sequential if I was to stay with the stock turbos.

 

Hmm... i've never heard of "simplifying", sounds good, but are there any downsides, how does it work??
The thought of getting rid of a couple of hoses sounds appealing..

but you still have a huge chunk of metal sitting in your manifold restricting flow......"dontcha know"?

poor man - not same performance....

 

jspec that pic is funny as ****!! does anyone know the increase in performance going non sequential? (ie horsepower, 1/4 mile time torque etc) i couldnt find that answer. thanks

 

there is [u]NO[/i] performance increase that comes with non-sequential!!!!!!!!!!!!! ALL it does is insanely increase the lag!!! there's still all the restriction, etc. (unless you modify the manifold), but even then not much.

Don't do it, you'll regret it...

 

much easier to launch
no transition "fun" when in the middle of a corner
less low end power, more midrange, same top end

 

my car has a dp mp catback intake and a pettit unlimited ecu with new turbos .So!!! would this mod be benificial???

 

Non-sequential is more for cars with "all the bolt-ons" and a streetport. It is like running a single turbo. Nobody complains about the lag of a single turbo. If you ride in a properly tuned non-sequential car at 15 psi you'll soil your panties. When my primary turbo was working correctly (will be again in 3 weeks ) I had full boost by 3200 rpms. Sequential is better for constant city driving. Non-sequential has smoother boost patterns - any of you NS bashers care to line them up from a stop or highway roll and take shot. You'll pull a 1/2 car at first, I'll sling past you - I've been in both a well-tuned sequential and non-sequential car. Non-sequential is a faster car overall period.
