I am considering making this happen or doing the 2.7 tt swap I may be in the wrong thread. (I am new) if I am redirect me please. Please don't come on here and say buy an s4 I actually have mechanical ability and funds so with that being said I am not a dumba$$ or a pu$$y and I will do the turbo kit or the swap. Oh yeah and I am actually a real car enthusiast I don't pay people to do my work. ( like everyone else).

 

Option 1: buy an s4
option 2: spend three times as much attempting to fit a turbo in an inferior car
Option 3: buy a 1.8
Option 4: leaving your twelve valve as is (this is by far the most popular option. Guys go slow and low)
Option 5: become a drug kingpin and get in tight with the Mexican cartels. Work your way up for a couple years and become an overboss. Fly to Switzerland to avoid federales and fall in love with a displaced Albanian. Run off to the Ukraine and buy and abandoned farm where you discover a rusted out Ford pinto and decide to put a turbo in it (still a better idea than putting one in a twelve valve)
That's pretty much it.

 

Lol I love option 5 very detailed. But if I can get my hands on a r titled running s4 for 1200 why not go that route and swap everything I mean everything cluster wiring all of it and for 1200 I basically have a s4.

 

Oh and I only paid 1500 for my a4 plus I have another vehicle to drive.

 

s4's are not that expensive. why dont you just save yourself tons of money and even more time and buy one. an even better option than this is to do a 4.2L swap. will bolt right up to the transmission ( in the 30 valve atleast, not positive about the 12 valve tranny) and you will have a V8 in your A4!!

 

While I'm not mechanically inclined enough to know what a 12v to 2.7TT swap consists of, a similar thread came up not too long ago:https://www.audiforums.com/forum/b5-...-build-154208/ (Actually this was a year ago; not sure what happened with it)

A 12v turbo build would require a lot of man hours and get very expensive in a short amount of time. Someone else can chime in with the logistics and the stats of the attempted 12v turbo builds that were abandoned.

If I were mechanically inclined, had the time and the parts, I'd do the 2.7TT swap

 

Ok let's make this a little clearer r titled s4 1200 my current cost of my car 1500. That makes a drivable clone s4 for 2700 plus if I build the engine and do the turbos during the swap everything will be done. Plus I get the fun of doing the swap. Yet again I am a true car guy I enjoy the challenge. Oh and find me a s4 in great shape under 8 grand and I will gladly buy it.

 

Ive been asking the same question bout the 2.8 12v swap...thanks for this thread!!! What do you need to swap in a 2.7 tt? How much power would you get ?

 

You need everything in between the front bumper an d front seats lol. Plus all drivetrain components so the gearing is the same. I am doing the cluster all wiring literally everything but I am lucky I found a wrecked s4 so its is a simple swap

 

Power is up to you as long as u feel like spending the cash to build the engine. Fyi buy urself a good torque wrench. I am building my own engine I want around 450 to 500I at the wheels
