well first of all thanks for taking the time to read this. i have been planning to Turbo charge my audi since i bought it 4 years ago. ive searched online for other 3.0l's that have been boosted and found just 1 and the parts list was in another language(i think german) i have a few questions if you can give me some advice it would be great.
1.what size turbo's should i use? im aiming for 350hp-400hp
2.do i need bigger injectors? if yes which and where?
3.will my internals be damaged?what should i do to prevent it or minimize it
4.i have the cvt tranny, will it handle the boost?
5.will i be able to use my stock exhaust manifolds?
6. do i need a bigger exhaust?
these are the ones i can think of at the moment if im missing something imprtant please let me know. and please dont tell me to supercharge the car instead.i just want advice on how to go about this project.thank you

 

1) You can actually do this with one turbo, not twins.
2) Yes you will need bigger injectors.
3) Are your internals forged? Is your motor set up for boost? If not expect to have to buy forged parts that are set up for boost. $$$
4) ??? I don't know the capability of this trans, see my other posts on tranny's.
5) Since it will be custom you can probably use them.
6) What is the current size of your exhaust?
7) What about programming your computer? Who will do it? You will need it done.
I say all of this since I supercharged my Z28 and had to do most of this on it.

 

Do yourself a favor and google search audi cvt failure. I personally would not invest any money into modding a CVT car. Also, adding a turbo to a naturally aspirated engine is often a tricky business that costs a lot more than you might think. Were I in your position and wanting a turbocharged V6 A4, I'd be looking at trying to find a B5 S4 in good shape; it starts with a 2.7 V6 twin turbo, better brakes, better wheels, better suspension, you get the idea. I've heard of 700+ HP 2.7T engines, so 350-400 should be reasonably easy to achieve.

Just my 2 cents - best of luck to you either way.

 

Good luck with the software.

 

4. don't heavily mod cvts. ask me how i know
