If you have a 2013+ Ford Focus ST with full bolt on performance parts (IE, air intake, intercooler, downpipe, tune and exhaust), then you have basically maxed out the power potential of the car.
So if you want to make more power, this is a turbo that is budget friendly, and keeps your ST fun to drive. We say fun to drive, because most bigger turbo options have quite a bit of boost lag, and when you floor your car and have to wait for boost to come on, thats no fun!
This turbo, has a few advantages over some of the bigger turbo options.
1) Cost- this is way less than more expensive big turbo options.
2) Appearance - this looks like a factory turbo, so even though its very difficult to see the factory turbo on the backside of the ST, if someone happens to see it, they'll assume its stock.
3) Because it has the same size inlet and outlets, you can keep all of your factory charge piping and run whatever intake you have thats designed to work with the factory turbo.
4) Response - because this turbo has a larger intake compressor wheel, but the same size exhaust wheel, you get a larger volume of air being moved for the same amount of exhaust flow compared to stock. This means you have minimal lag over the factory turbo.
With this turbo, you simply bolt it on, and then get a custom ESP tune for your ST. We saw a gain on 30whp by simply adding this turbo, custom Turbosmart wastegate, and a ESP tune. This is a good options for people who want a little more horsepower than the stock turbo. This is not a big turbo replacement.
This kit is a turbo cartridge and cast inlet and outlet. You reuse your factory turbo exhaust manifold and internal wastegate (you can upgrade to one of our custom spring wastegate if you would like)
