Title: How to make a AAZ K03 Hybrid Turbo?
Post by: RockOcean on April 19, 2023, 09:11:33 pm

What all needs to be done to make a AAZ K03 Hybrid Turbo? Is it just a K03 AHU Turbo Cartridge inside the AAZ K03 housing or is it more involved then that? I would imagine so but can not find any info on exactly what needs to be done.

Curious why you;d want to do this/what the benefits are...are you trying to make a good aaz turbo?

Multiple websites sell these stating "100°F reduction in EGT and gains of approximately 8 HP and 15 lb/ft of torque." Just wanted to know how I could build one myself.

Those 2 turbos are quite similar volume-wise if I remember correctly but I cant remember the ARs. This seems bogus to me, I dont know ho you;d get either of those gains with just swapping the cartridge. AHU is intercooled...those numbers seem like the kind of gains you might get intercooling an AAZ...I might be wrong.
