Compressor is actually billet aluminum. The exhaust turbine is titanium aluminide material. Technically if you did a billet titanium compressor wheel though you can make the fins very thin and pretty light.

 

gotcha

 

any updates on your decision? i have a similar set up like you and have a standard facing JDL t4 kit and im wondering if i made the right decision on the turbo. i currently have a 6266 1.00 a/r. i don't have access to e85, so im trying to get 550 or 600whp on 91oct with the fastest spool possible.

 

Well some things have come up that have forced me to re-evaluate how much money is going into this. I've decided to keep the turbo setup and more then likely upgrade the turbo and either use it (turning down the boost) or get a smaller turbo after all).

My motor is more trashed then I originally thought so I'm having to build a new short block. Most of my money is going into that now.
