turbo- stock or aftermarket?

[new big toy]

i have a 99 f-350 and im wondering about the turbo, it says on the compressor side garett and on the output it has 1.10ar. would this be a stock turbo? also the 1.10ar does that mean for every 1 cubic foot of air that goes out of the engine it puts 1.1 cubic foot in ?

new to turbos here, thanks

Stock early 99 turbo... .84 exhaust side, 1.10 compressor side.

are their any companys that sell larger compressor housings and wheels to upgrade the stock turbo or i just have to go to aftermarket turbo

yes there are but the aftermarket turbos are the best way to go. after you spend the money to change the stock turbo you are almost to the cost of a replacement turbo
