hi guys i have a 91 capri xr2 and i replaced the CHRA on the turbo a while back trouble is when it cam back the compressor wheel on it was too big ,...so me being a retired ase tech i figured i could port out the housing on the cold side to match it with my dremel ,... well i did it and its been running for like a year but it just does not have the boost that it once had and i know its my porting job which is good in the fact that i made it work but the clearances i thing MAYBE A LITTLE TOO MUCH LOLOL so if i measure the wheel with a digital caliper can someone tell me what housing i can use or what should i do to get the proper boost out of it??? i have an extra housing i think its a vj 11 not sure but anyway let me know and thanks in advance
