Thread: Upgrading my Turbonetics T76 (.98 ar) NEED HELP !

  1. #1

    Upgrading my Turbonetics T76 (.98 ar) NEED HELP !

    Hi dudes,

    I just recived my stuff from Nelson Performance (Turbo, Camaro SS 2010 Tuned, etc) and got some problems Installing my New Turbo.

    Only thing that bolts on is the T4 flange, other than that I´m clueless for now.

    I wanna be the Biggest Front mount Turbo instaled around here...humm, forget it, I´m the only one !!!

    Any way, can you help me with the flanges and stuff, and also what Heat Jacket will fit this sucker? (t4 or T6)

    Thanks in advance for all the Help. Some pics.

    ya, it is quite a bit difference, gonna need a 3.5" vband for the exhaust and 3" vband for the cold side.
    i'll look into it and get something going for you.

    No, it's not a MP T88... Looks like a MP45. Has a 76.5mm compressor with a .60 a/r and a 77.5mm turbine wheel with a 1.22 a/r. Mp rates this turbo at 7-900 fwhp. they have been making these for quite a while. Its the same compressor wheel they based there T76's off of.
