I just put a TE44 on mine and worked extensively with Pete Tompka to get his cold air kit to fit. I had to finally Mike the Outside Dimension of the Turbo Inlet and have the piece custom made.
Nobody knows why, but the standard fitting that comes with the cold air kit, designed for the TE44, no longer attached to the inlet bell. John Craig claims his turbo hasn't changed, Pete claims his fitting is the same one for years.
In summary - Measure with a micrometer if you are using the Tomka (Kirban) cold air kit.
