Reverting non-sequential to sequential?!?!
Reverting non-sequential to sequential?!?!
I was wondering how I could go about converting back to sequential? Purchased BNR twins that have been modded & I'd like to try to get them sequential again. How would I go about that, if it's even possible?
I attempted to search, but couldn't find anything.
Thanks!

Just reverting the turbos back? Do you have pics of the turbos? Then I could tell you exactly whats needed, but most likely the pre control flapper was removed entirely by Brian which would make it a costly reversion.
Going to a single small turbo when have been the best alternative. Should have done more research and analysis.
You would need all the solenoids, tanks, one way valves, actuators, and wiring.
Very expensive to go back to the inferior system.

Nick and I are building his engine - the car is a sequential car, he just got some used BNR's that were set up for non-sequential.
Spoke with Bryan at BNR, I am sending him a spare secondary turbine housing for him to machine to accept the upgraded BNR turbo cartridge. According to Bryan all BNR turbos use the same machining, so going back to sequential or vice versa you're good.
The problem is the flapper door for the precontrol has been removed and the hole plugged or welded shut. So, I have the machine work done on the spare, then when the used BNR's show up, unbolt the old turbine housing, bolt on the new one, and done. Also, the precontrol actuator will need to be added back on.
