What are the benefits of non-seq? Do you really get more HP? You guys that are running non-seq, do you like it?

From what I hear, runnin' non-seq. has no real advantage in horsepower. If you think about it, the same amout of air is being forced into the motor, just at a the same time now, rather than at different times. One advantage of runnin' non-seq. is that it simplifies the rast nest (vacuum hoses). If you run non-seq., you will get a little lag. It all depends on when you want your power. If you want it up front, stay seq. If you want top end, go non-seq.

less clutter under the hood and easier to work with from what I gathered...

I've had 17 FDs, 14 of them were running/driving cars. I've never had a problem with seq other than a hose popping off the top of the pressure tank.

Non-seq only real advantage is under hood appearances. It does ditch a lot of hoses, actuators and solenoids.

I am into road racing so smooth managable power is the key.

Try to simple poor mans and see if you like it.

i just got my car converted today!
1. you get better gas mileage cause your turbos arent spooling up at 2,300rpms
2. NO turbo trans
3.Less worries about Seq failure
4. a good chance of a better 1/4 mile "depending on mods"
5.Helps you get ready for a single turbo by removing all those cables and learning how the lag feels

i tried the poor mans non-sequential and tried it out for a week. i didnt really notice a huge difference in the top end and i missed the quickness of spooling with the sequentials on city streets, so i went back. now i have my AVC-R diled in so good my transition is almost seamless. i would leave them sequential especialy if you dont have problems with them currently. go single if you want lag and tons of top end.

i would say, just leave it as is and when u get seq problem then go with non-seq....

regardless of seq or non seq...after all at 4500rpm and above you are running twin turbo.

Didn't notice a difference in the quickness of spooling, just had to shift to get into the powerband. Daily driving is better in my opinion. If you want the power, just keep the car where the power is...a bit higher in the band for NS.

no boost spikes with no seq, correcto?

TracyRX7

I've read in a few places on the forum that some people have gone non-seq and have made both turbos spool around 2,600-2,800 range. This would probably be bad for a daily driver since you'll be heating stuff up more and running both turbos a lot but may be very nice for autocrossing

All of the stuff I can find just mentions its possible not anything about a howto and I'm years away from figuring out how to do stuff like that on my own.

Keep in mind that "spool" and have "full boost" are two different things.


The difference is the power you have down below 4500 rpms, you just move that to the around around 4500 rpms. It's not more or less power with the "poor-mans conversion" just a difference on where the power is located. With the FULL conversion, the flapper doors are removed which can result in less restriction thus a little better flow (which can add some power).
