FD3S RX7 - BNR Stage III Twin Turbo Upgrade - £2450
We are proud to announce Lightning Dynamics are now supplying BNR Stage 3 Twin Turbo Kits as a complete package.
These are a direct bolt on with no modifications required to engine or running gear.
These can be used at stock boost levels but we advise Uprated Fueling, Intake & Exhaust together with our Uprated Solenoids System for maximum efficiency and power gains.
Delivery Time for Turbocharger packs is currently 6-10 weeks  


The new BNR Stage 3's have many improvements over the factory HT12 turbochargers. The factory HT12's are not rebuildable in most cases. The stage 3's however are not remanufactured turbochargers. They have new CHRA's (Center Housing Rotating Assemblies) and the factory end housings are machined to fit the new CHRA's. The Stage 3's are not rebuilt or remanufactured.
The turbine wheels have larger inducer and exducer measurements over stock giving the turbine wheels more leverage to push the larger, more efficient compressor wheels while decreasing backpressure in the turbine housings. The turbine wheels have more blades giving it even more leverage than before and also the wheel casting is much thicker than stock. In an event of a blown apex seal, the turbine wheel (more than likely) will survive, unlike the stock turbine wheels in the stock twins or the 99 spec twins which are a very thin cast that will be heavily damaged. Apex seal damage will cause slow spool, inadequate boost, and lack of power. The shafts in the stage 3's are 1/4" in diameter compared to 5mm in diameter like the stock/99 spec twins. Also the shaft has left hand thread shaft nuts which eliminate the issues of shaft nuts shooting off like the stock turbos have a tendency to do under high boost. It can lead to engine failure if cases are bad enough.
The thrust bearings are upgraded to 360 degrees for proper lubrication of the rotating assemblies up to 180K rpm! This means you can run a tremendous amount of boost without killing thrust bearings. The stock thrust bearings are 270 degree bearings which aren't reliable to run over 15 psi of boost. 360 bearings are standard on BNR Stage 3's.
The stage 3 comes with an adjustable wastegate actuator. This allows you to turn up or down the boost mechanically w/o an electronic or manual boost controller. The adjustable actuator can also make the boost controllers more effective because you are working them less to turn up the boost.
The stage 3's can be ran sequential or in non sequential forms. When sets are ordered, please include complete Y pipe for modifications. Extra charges will be given to customers who want a full non sequential conversion. A one year warranty goes along with each set of BNR Stage 3's. We have an additional core charge for turbocharger purchases.

With the BNR Turbo's, we advise the use of our Solenoid System. Our System is specifically Designed & Built to be used In conjunction with the BNR Twins for HIGH PSI applications.
