Ed I emailed him my number last night and he replied saying he was going to call me today sometime.
Once the exhaust wheel is damaged at all you can't use them, the turbo would just flog itself to death. The exhaust measures the same as the CT12A off a 1J so you may be able to get the turbine and shaft out of one of them and fit the bigger compressor wheel to it. Or, I'm lead to believe that the steel exhaust wheel off a starlet will fit but I don't know how true that is. Both turbo's were originally rear ones which only do anything over someting like 4000rpm and look brand new. I chipped the wheel fitting the front exhaust housing to it in an attempt to make a complete set.
