BNR in parrallel
The BNR in parallel I take it is the same as the seq running non seq? If this is true then what kind of lag do they have? I need new turbos and need help in deciding what i realy want. I want more power than stock but dont realy want to compromise spool up time. I would like to eventualy get 375-400 RWHP keeping it totaly streetable. With the BNR is better to run them seq or non seq to get rid of the vacume mess? Thanks the input any info will help, I just dont want to wast my time or money on something I dont realy want.

Yes, parallel=non-seq. Which way you choose is up to you.
See this thread for lots of good non-seq lag info. https://www.rx7club.com/forum/showth...hreadid=212299 It seems that you can get full boost by 3500-3800 rpm with a dp, mp, cat-back.
The BNR stage 3's should be able to hit your goal of 400 rwhp, but it'll take some tuning to get it done right. GoodfellaFD3S has stage 3's non-seq, you should talk to him for lag specifics.

As far as running them non-seq or seq, it depends on when you want your boost. There is lag, as with any single turbo setup. You just need to think if that's something you want. Some people don't mind, some people do.

I'm the guy who bought kwikrx7's (Barry's) car. The seq. BNR2 setup is really nice. I've got a dyno sheet from KDR of the car putting down 366 hp at the wheel. KDR claims that dyno session was off by 15-20 hp at the wheel because of a bad diff. in the car (it's since been replaced). The setup has 15psi at 2800 rpm and pulls nicely from 2000 on up. It's nice not having to downshift from 5th gear on the expressways when you're changing lanes in everyday traffic.

The BNR 2s are much better run sequentially IMO - I had an old set of BNR 2s with the 2nd gen compressor wheels setup FULL non-seq and had full boost by around 4500 rpms - I did have a bad diff at the time so this might have contributed to the lag. Had the turbos sent back to Bryan and he put in new compressor wheels designed for tip speed - had Dave at KDR them up seq and they felt great - they definitely provided more low-end torque and overall power than the stockers
