Sequential boost problem. Thinking about going NON. Advise??
 

I discovoered the reason my secondary turbo isnt engaging is becuase the selenoid next to the secondary BOV, the one mounted on the Y pipe is broken. A piece of it broke off, and now the secondary turbo doesnt engage.
Anyway, by eliminating it i could go to Non sequential i think. Thats what i was told anyway. What else do i have to do to go NON?? is this a good idea? how long does the process take??

search bro, noones gonna answer this cos there is tons and tons of info on here for this, just search

Shell out the cash for the solenoid. Going non or single defeats the purpose of having an FD. If I wanted something like that, I would have bought a WRX. Just my opinion. Some guys love single and non sequential.

You've obviously never driven a single turbo rx7. I agree non seq sucks

Going non-sequential because you have to replace a single easily accessible solenoid?

IF you know the cause and were happy before, just fix the problem. IF the cause is unknown, or you weren't happy beforehand, just go nonsequential. Myself included, every FD owner I've converted a car for was ecstatic about the results and said they'd never look back, especially once I explained that they now had 4 vacuum hoses under the intake instead of 74.

yeah, i think i will just fix it. It is really easy to get to, i just thought id see if anyone liked the non sequential setup. I know ive heard of a lot of ppl doing it, but appearantly the sequential works better.
Anyway, would mazda sell me one??

You must be talking about the charge control valve actuator?

i think so yes. its the one next to the secondary BOV right? mounted on the Y pipe

Yes, that is an actuator, not a solenoid. IT should be easy to find, and if you can't get one, I can probably dig one up for you for a few bucks.

I would really appreciate that man. PMing you now

So anyone else have anything? Ive heard some good things about 1/4 mile times with non sequential setups. Is this true??

Hey man....I have done the full non-sequential setup already and love the results. However if you need that part I have all of my parts in a box and I know that I have the valve or solenoid that you need. Take a picture and post the part that you need I can easily have it handy for you in a couple of days. Just let me know!

There are small power advantages to the FULL non-sequential conversion, due to small areas of cleaning up the airflow. People can pull just as fast of times at the strip with sequential.

People always seem to get so worked up about this, the facts are: in hard driving, you will almost always be above 4500 rpm, either in road racing or drag racing. Auto-x is the only type of aggressive driving where you will be below 4500 rpm. The advantage of seq is that you actually have good throttle response in town driving and on the highway without having to be revving at 3500+ rpm all the time. The advantage of non-seq is that it is a much more reliable and consistent setup, but then the car is less fun to drive in "normal" driving.

Hey Kris,

Ask Art why he purchased another manifold (because he hated non-seq and is going back to seq). ;)

Another advantage of nonsequential **COULD** be increased gas mileage, if you can keep yourself out of boost. For instance, on a sequential car, you have a low end surging feeling at the least application of throttle. Nonseq. gets rid of this surge, and makes the car a bit more hesitant to boost. IT's easier to drive, more linear, predictable, and more like driving a standard single turbo car, like an FC.

I'm the only FD owner I know, so I haven't had the pleasure. I don't like single turbo cars. Not to mention I don't need the gobs of power a big single provides. I don't think I'm up to it as far as my driving ability goes. I'm no Andretti and I know it.
