t6 means you can mount the exhaust housing at a different position when you put it back on. the compressor can also be "reclocked". one thing to do is contact a turbo company with measurements from both wheels and the housing #'s. they may be able to tell you more on how it will fit your application. for instance my turbo has a 4 inch input on the compressor and 3'' outlet. if you just run it, keep tabs on how fast the turbo is running by the sound. if it spools too fast in rpm, it can be damaged. tom
