Pair of NRE Mirror Image 61mm Turbos
Have a pair of Nelson Racing mirror image 61mm turbos with about 10 dyno pulls on them. These are a symmetrical pair [left hand / right hand rotation] T4 base with twin scroll turbine housing and polished compressor housings. We purchased one pair for initial dyno testing, and they proved a bit to big for our application.
These made well over 720hp and 35psi boost running on a single scroll, and sounded wicked on both ends. See video. They are a water cooled cartridge, and would be perfect for a 1000-1500 hp gas or alcohol application. Paid $5500 for the pair. Asking $4000 OBO https://cimg0.ibsrv.net/gimg/www.off...356d94646b.jpg https://cimg2.ibsrv.net/gimg/www.off...f320e3c9c1.jpg |

Ya miss that part about fitting 1000-1500hp builds? These are basically two GT40xx's, in left / right hand rotation.We stepped down to a single bullseye S476/87 cause 400ci spinning 4k couldn't get these into the power map.
The exhaust housing are cast to accept spool valves. They performed decent for us with single scroll blocked, but opened up they need a bunch of CFM. https://cimg5.ibsrv.net/gimg/www.off...d81e079fec.jpg |
