i have a big garrett TV7512, i was told when i got it it was a GT42. and it look similar. so i wanted to know if i can buy the GT42 T4 rear housing and the nicer looking GT42 front housing with the V-band on it. since i want to run my piping with a V-band anyway...

this damn thing is huge though. anyone run any of the TV series Garrett turbos. I seen a bunch of V8 guys run them.

here some pics...

 

ok, trying to answer my own question here. but still need help i think.

i measured the inducer and exducer of the turbine and compressor. did the math and got a turbine trim of 77 (hot side). and a compressor trim of 56 (cold side). GT42 crompressors are a trim of 56, so if its the same diameter where it v-bands to the center cartridge, then i can swap the front housing. but i havnt seen any turbine housings that fit a 77 trim. i called the guys at Tial for there very nice GT42 turbine housing. he siad it would have to be a 84 trim to fit.

anyone know where i can purchase aftermarket or stock housings for a GT42? im going to replace my ugly bulky front housing and keep searching for a T4 77 trim housing.

any info on this could help too.
