This guys are hands down the best turbo specialist in South Florida. Well worth the 2 hours drive. Got my Perkins Marine turbo Remanufactured and all I can say is wow. From a rust bucket to a brand new looking turbo in 3 days exactly. Just as promised, and the best part is I saved over $1k compared to the cheapest price I could find. They just got a life long customer.
If you are looking for a true turbo specialist, give these guys a call. Highly recommend them!
