I'm a little confused on why anybody would get BNR stage 3's and run them non-sequentially as opposed to getting a single turbo? The benefits of keeping the twins are obvious (no lag) but it comes with the headache of the rats nest. So why if you're planning on experiencing lag do you not just go with a single turbo or run the BNR's sequentially?

 

I am no pro here but i will take a wack at it
Its more how the bnr's put the power down (non seq) ya there is a lil lag but its a smooth pull and u can keep traction where most single set ups there is no traction once boost hits in lower gears

 

It may work for those that have visual inspections

 

I agree with the OP , In all honesty .. The Rats nest isnt even that complicated . Its just a bit of piping if you study the rats nest diagram its Not even that hard to figure it out .

i've diagnosed , fixed , redone my rats nest a couple of times nad have had perfectly working twins for 4 years . aslong as the rats nest goes .

I just went single this winter . Because of Heat , and If I could I'd go back twins I miss the instance response of the sequential twins .

as for why run them None sequential ?? I dont know ,... the little extra power you gain is not worth the loss of low end torque .

 

It is all up to the individual's preferences. A properly setup single turbo car can have no more or even less "lag" than a twin turbo car. The main benefit of the BNRs are the ability to keep sequential and emissions, a better chance at passing a visual inspection, and significantly lower cost. Non-sequential twins trade a little response for simplicity and slightly better flow if the conversion is properly performed.

 

This. Smog *****. I'd love to cool off and clean up my engine bay.

 

+2 on the smog *****.

Another reason that the installation is simpler to use the BNR's as they can easily be swapped in using existing components. But you'd better have an ECU and depending on your boost level also injector work. At a minimum with a single you need an exhaust manifold, wastegate, DP, IC hot air pipe, intake, injectors, fuel pump, and an ECU.

Remember this is just bare minimum as most people (if not all) would have full exhaust, IC upgrade, ect...
