Why Single Turbo
As a novice, I understand that all 1993, 94, 95 RX-7 FDs imported to USA had Twin Turbos. I see discussions of single turbo RX-7s. Are the twins being replaced by a single? Is one of the original turbos being disabled? What is the reason and benefit of the Single Turbo?

When your stock turbo system starts spitting oil everywhere you are forced to make a decision of sticking with the twins or going to a single turbo. The twins don't do well at high elevation and the single turbo set up is much simpler, so I went with single turbo set up. The only issue going single turbo is the cost of doing so. you basically need to beef up a ton of items on the car when you go single if you are going to run more power. fuel system, clutch, intake, intercooler, turbo and everything with the turbo, ecu, brakes, etc, etc.
it is a large commitment. Most single turbo's spool well with new technology ones and also produce more power with new compressor technology/machining/designs.

Usually when guys change to a single it is because of one thing..you can squeeze more power out of the car.
The downfall of this is the cost and part that need to be addressed when doing so.
You can't slap a Bigger single turbo on the engine and expect it to run with the stock ecu.
All the fuel and ECU issues along with the Turbo setup itself must be acquired to get the engine to properly support the new stuff.
Upgraded BNR Turbos can be installed to replace the stock configuration...I am not sure however if they require changes to the fuel though.
The outcome of this mod will put a smile on your face but a dent in your budget,so if you are satisfied with stock then don't let someone tell you it's NO GOOD and to "upgrade".
They don't control your bank account..you do!
By the way you should be able to find research on the difference of Sequential and non-sequential systems in the 3rd gen tech section.

Thanks folks for the good inputs. Now that I understand the concept of single turbos, I think I'll stay with the stock twins until I have a problem.
