I had a Super16G on my 2G like 3 years ago. It was a POS. The hardware was junk and the studs provided stripped regularly. The adapter place was a complete POS. The spacer to move the manifold away from the block was genius....lets add a SECOND exhaust gasket for possible leaks. I regularly got stomped by similar cars with the more responsive small 16G. The only place that 10CM is going to help is maybe really high boost levels, and RPM's. I never realized the benefts of it on my car. The turbo itself worked fine. It's just not right for these cars. I wish I had kept the e-mails I have back and forth with Mr. Hahn and his POS hardware. The long studs stripped out in the turbo to mani adapter plate....yeah he charged me for new ones when it was clearly a design fault. Hahn sucks.
That's just my opinion though....
