i heard 3500 too, a lot of people that i have talked to say that they would go back to sequential if they could because they missed the immediate power that sequential gives you. If you go non you have to wait till 3500 to get thrown back in your seat.

It all depends on how you're set up. If you do the full non-sequential the correct way it ranges between 3200-3500, if you do poor mans it's full from 4000-4300.

with my mods at full-non-seq. I see full boost at 3k-3.2k rpm. trust me I found out the scary way today. I was looking for a boost leak and I found it. took the car for a spin and the freak MAP sensor hose came off. Scare the SH*T out of me.

I honestly don't know why so people have issues with the added lag of non-sequential. I drove sequentially for two years at 12psi and enjoyed it. However, I've been driving for a year non-sequential, I see full boost by 3800 and I have absolutely no complaints. I'm very happy with my decision.

I wouldnt do it without a completely open exhaust and intake tho.

My car with full non-sequential starts making positive pressure at about 2300 rpm and gets 10 psi by about 3600 rpm.
If you think full boost by 3500 rpm is laggy then you really don't have any choice but to stay with the stock sequential set up. Full boost by 3500 rpm is very quick and you still have 4500 rpm of power band. It isn't like a large single that gets 10 psi by 5000, giving you only 3000 rpm of power.

it doesn't make more power but it gets rid of the complexity of the seq. system and the small dip on power at 4500 rpm from transition. I also notice I get better gas milage. I don't get spikes either. Oh and another thing I notice last night, with my Greddy Profec B (original one), I get to full boost faster, I hit my 12 psi at 3500 rpm the the hose came off. I just recommend find some one with the full non-seq convertion and take a ride. You be the judge if YOU like it or not.

i still cant decide....this decision has bothered me for a long time....
i used to have a skyline R33 with a HKS GT2835,and the full boost comes up at around 3500-4000 rpm.it is simple and soomth,but the low rpm power output really sucks~
im thinking maybe the revy nature can fill the lag up.
how long does it take to get to 3500rpm with a full non setup?

I have never tested that since when I'm going to boost it am doing 2500 rpm already. I actually don't have a place where I can floor it out of the hole here since that would be out of a intersection and the roads are pretty bad there. The one time I did I had traction issues so that pretty much make me be a little more conservative on how I boost. I have the sharp setting on my boost controller at about 1/3 the way up and boost still come to sudden.

gfelber sounds like you've got a really nice set up. I am running non-seq and I love it. When it's raining I can drive all day and never get into boost. When its dry I break traction at 70mph in third at about 4200rpm which my seq stock set up only dreamt of. I start to see boost at about 22-2500rpm and Im full on by 32-3500rpm which is only a second in any gear. It still does smoky burnouts in first, infact from a dead stop letting off the clutch(9'5lb flywheel) at about 1500rpm with in 100 ft or so im breaking traction. So yes I'm extremely happy with my set up.
Oh btw most of the time i only see 7psi b/c I over ported the wastegate. I don't have a boost controller yet and was worring about spiking when i did the mod. On cooler days I'll hit the 10 psi mark.
I do think the flywheel is part of the success i've had with this.

I had the full non seq done on my second Rx7 and regular seq on my 1st. I like the non seq better because the power is much more linear, with the seq it would pull a little, then pause then both would hit at 4500. With the non seq you wait a little until about 3500 and it would hit hard and pull all the way to redline. I found it easier to drive/race, and i liked the smooth power better. Im now going with a T78, so i will have a little more lag but a lot more pull!

The seq setup never gave me the feeling of how a turbo car should feel with the lag at 4500rpm. By 4500rpm the car should be screaming and getting more powerful. I would take the 3K lag over the 4500rpm drop in power anyday, especially when you can compensate for that by just learning to downshift and feather the clutch. To each their own though, but you might be surprised after you ride in a non seq how different it feels.
