The stock specs on the Syclone turbo is smaller that the turbo size you suggested.
A Td06 Mitsubishi stock type turbo will work fine, dont need to spin it as fast to make 12-14 psi.

That is why I suggested a small turbine housing to get fast boost responce, he is not looking to make a track car w/high boost.
Previous post.
BTW,
Snowman is looking for a daily driver,good mileage,boost quickly,low boost all on his stock longblock.
He has a manual trans.His engine is a 250, not a 292,this makes a difference.He wants it to hit full boost close to 2000 RPM.
His engine is not going to turn high rpm for now & needs a combo to work w/what he has now.
