Is there any advantage switching from sequential to non sequential? If so, how do you do it.

im still working on my conversion... but the way i see is no more transition period combined with a much cleaner engine bay. it really is much more simplified. the reason its taking me so long is i dont have that much time to devote to it and im really finnicky about things so ive taken time to really do things right. Plus i see the added benefit that if something goes wrong i dont have to spend weeks diagnosing the problem.

this link here seems to be the best reference so far.

Power wise there isnt really a difference takes a little longer for the turbo's to spool and they both hit at once, kind of like having a single. You wont really notice a difference driving around town, but when you get one it you will. Also free's up more room in the engine bay and makes the car easier to work on. And my personal favorite NO More Rats Nest, you'll only have like 6 vaccume lines. It really all boils down to prefrence, and if you have the time, patients, and money to do it. Hope that helps.

The only advantage is that it is easier to troubleshoot since there are less vacuum lines and solenoids.

The disadvantage is much less torque and power under 4000 RPMs and not being able to pass smog.

Besides a cleaner setup under the UIM there is a power increase if:

If you do the seq conversion 100% instead of the normal 80% like most due, you will make more power past 4000 rpm due to less exhaust back pressure. This requires using a Dremel or die grinder on the exhaust manifold and turbo housing ports.

Then if you bump the boost up to at lease 15psi, you will make more power across the whole rpm band than the stock engine.
350whp non-seq is always stronger than any stock engine! Then the low rpm turbo lag is a mute point.

There have been many discussions on this in the FD forum. Go find them!
