The dealer. Do you know that Cat gives special discounts to truck manufactures? You can normally buy the same part from a truck dealer, even after markup, for less than direct from Cat. JM turbo has awesome prices. I read mixed reports on these Chinese turbos. If you use the search block at top right might get some good leads. Sorry I don't recall but one highly recommended out in NC. and some others.
I got a brand new OEM VGT turbo for my Detroit less than a year ago at D&W diesel and it was $500.00 less than what the Detroit dealer wanted.
Been a few years since I bought one but Superior Turbo in Blissfield Mi treated me great and had the lowest price I could get on a Borg Warner. Nice guys.
everyone said you can't change the actuator. they wanted to sell the turbo found a place that has a replacement actuator 49.95 a hole lot cheaper then turbo..
Turbo Exchange out of Concord, NC is probably what BoxCarKid is thinking of. They're not selling Chinese knockoffs, or weren't 5 or 6 years ago anyway, and have good prices.
