    GTA4502BL garret # 750432-4


    Anyone know where i can get a turbine housing for this turbo? wanting a smaller A/R ratio and getting rid of the internal waste gate.


    compressor inducer 69.5mm exducer 102 .66 a/r
    turbine inducer 87.3mm exducer 80 mm 1.33 a/r


    all measurement are me measuring.

    When looking at garrett's website this turbo is like a cross between a gt42xx and a gt45xx. then turbine house measures very close to the gt4202 turbine housing.
    Any advice or knowledge would be great thanks!

    Seems like it's a GT45 turbine to me... will a standard GT45 housing not bolt up?
