The only things I can really tell you is if you've got a '99.5-'03, you've got that redesigned compressor wheel that sucks. You can replace it with a Wicked Wheel or Banks Wheel. Your compressor inlet is 4".

early 99 turbo had a 1.10 compressor with the older style compressor wheel. I think it's a 60mm. The turbine housing is .84

Late 99 had a 1.10 or 1.0 compressor housing with a newer style compressor wheel (same size as the early 99) that surged. The turbine housing is a .84 also.

Compressor inlet is 3" on a stock turbo. Ported shroud housing has a 4" inlet.

Really? I've got a ported shroud housing, then.

Are you absolutely sure about that?

Yes the inlet(intake) tube tapers down to 3 inch were it goes in the turbo

Aftermarket ATS Housing,38R, TN BB, H2E are 4 inch inlet

I just ask because I had bought a boost leak detector from DIESELSITE & got a 4". It fits snug on the inlet. As far as I know, the only mods to my turbo are the compressor wheel & WGA. The truck was bone stock when I bought it.
