This turbo started as a Garrett GT 4202 We clipped the wheel and machined the plug for the wheel to insert 1/8" into the plug (per the scheid rules) the plug is tig welded on the cover in 3 places but can be removed without damage. It has never been ran we went with the gtx 42 instead. I have the 1.01 housing and the 1.15 housing you choose witch housing you want.
