k04 turbo upgrade
I have been looking for turbo upgrades for the 180tt that will not hurt reliability and are affordable the k04 turbo seems like the right turbo. lets say i get 3 inch turbo back exhaust an intake and a chip that would put me around 230 hp right. So how much more would a k04 raise my horsepower and torque. i know there are different types of k04 such as the k04-20 would these turbos just replace my ko3 or would it be more than a bolt on and if so what would i have to do. thanks

RE: k04 turbo upgrade
you will need the ko4-001. This is a direct bolt on to the 180's. It is however smaller than the ko4-2x, it has the same compressor as a ko3s, but with a larger turbine to hold boost longer and increase flow. People have seen ~220-230fwhp with these and all the bolt ons. The ko4-2x is bigger on both ends, but will require a whole new setup, not a bolt on.

RE: k04 turbo upgrade
220to230 with the new turbo i was expecting these results with the 3in turbo back exhaust along with chip and intake. the guy at the exhaust shop said a 20 to 25% increse in hp on the exhaust apr claims 20 to 30 hp on the tt and a intake claims 5 to 8 are these numbers bogus because if they are true wouldent i be looking at 240-260hp or is that not at the wheels would the drivetrain realy suck up that much power? sorry for all the questions im new to moding cars

RE: k04 turbo upgrade
so, in my TT 180 Quattro Coupe AWP if I picked up a ko4-001 and wanted to do a direct bolt-onwould I stillbe okay with the stock SMIC?
Additionally, if I wanted to chip the car, what would the end result be looking at with the chip + K04-001?
I'm looking for a minor performance increase for now, so I can really put some money into suspension upgrades.
I already have a dual exhaust setup. I guess mine came stock on the 180 AWP, because my vin says I have factory dual exhaust. I also have a forge 007 DV. Other than that, i'm fully stock.

Additionally, if I wanted to chip the car, what would the end result be looking at with the chip + K04-001? - it will get you just over the 200awhp (more drivetarin loss)

RE: k04 turbo upgrade
Powerwise: chip--> exhaust--> water/meth injection.
Those three would give you the biggest power gains in that order. Plus you can add things like tips and ic's to free up restrictions/reduce losses.
