The small one builds boost quickly while the other covers the top end. One benefit of two turbos is to have a small and large one in sequence (aka sequential turbos). Notice how it takes a bit to get going but then blasts off:

Larger turbos take a bit longer to spool up and build boost, but they will pull strong in the upper RPM's. However, they don't build as much boost at higher RPM's. Smaller turbos spool quicker, so they build boost at a lower RPM. And the exhaust tone is MUCH different from stock twins to aftermarket single Of course when you get into things like newer turbos like Precisions billet line of turbos, is when things really start to change.īut a properly working sequential twins on an FD is way too much fun to ignore. (All in, you can have a great 350-450hp setup for about $8k, and be dead reliable for daily driving on a well maintained engine) For either of these kits, its not uncommon to make an easy 400hp with very little needed for supporting mods, short of some fuel upgrades, ignition amplifier and aftermarket ECU for tuning. Older turbo setups from Apexi's RX-6 Isamu kit or Greddy's TD04-18G kit offer quick spool, cooler engine bay temps, and higher potential for power production. The bad parts about having the OEM or BNR twins, is that they retain a lot of heat simply due to how physically small they are and the rotaries hotter exhaust temperatures.įor the FD, most people have noted that simply going to a small single turbo setup, is far more efficient at making power, while still retaining low-end drivability. Mazda took Porsche's cues with their sequential twin-turbo setup from the 959 (as did Toyota with a similarly configure sequential twin turbo setup on the MKIV Supra) All the benefits of sequential, but none of the frustration of troubleshooting the many solenoids and vacuum hoses and such.
