B7 2.0T Engine swap with 3.2 V6 or S4 V8?

[Hockenheim]

I plan on keeping my car for many years, however I'm at 70,000K, plus I wouldn't mind more power,

How hard would it be to swap in an S4 V8 or even an RS4 V8?

Should be a direct swap right? Or even a 3.2?

I have 6MT as well,

Anyone ever considered this

2.7t Swap!

Id do the TT-Rs I5 motor swap if anything.... But that is just me..

def don't do 3.2, those things are slow and cannot add power. better tune yours and you're already there.

[a4_matt]

Oh hai!

hi-ya

It will most likely cost more money to put a 4.2 v8 in your car than if you just went out and bought an S4. I agree with everyone else go with the 2.7t, a few of us are looking into buying a cheap B6 and doing that swap for fun. Then you can really build the 2.7t to your exact liking.

All of the engines you mentioned are possible. 2.7T is similar in shape to the 3.2 so it's also not bad. If you need help let me know but my swap has been fairly cheap and easy

However, if it was me I'd do the 3.0T

I'm planning to get a B-pillar cut of a 2.0TDI 6MT quattro from Germany and swapping everything over. Better turbo, injectors, tuning, etc. and I think I can be at 250HP..... and over 400 FT-LBS of torque. Off the line you may take me but let me rev up a little... oh wait, it's called a "boosted launch". And I'll still get better mileage too. Sure you can get them in Sweden, etc. but for some reasons they don't bring them to the States, so I'll have to make my own.

That would be cool

[DRAKLORE]

Talk to PNB7, he did a turbo VR6.... Be prepared to spend well over 15/20k$ to get it right..

I would do 2.7T, or the 3.0T. 2.7T would be a little easier and cheaper with more available parts.
The 4.2 has been done on the B6 platform, the engine bay on the B7 A4 is tiny and the 4.2 is a really tight squeeze. Pair that with a custom backplate to mount the 4.2 to your 6MT and it's still a lot of work when you could have had a sweet 2.7T swap

Id still take the TT-RS I5 as the old ones were serious monsters....

The current TT-RS motor doesn't have the the mounting bosses on the block for longitudinal fitment. That would necessitate a lot of custom motor mount work to get it to fit right, in addition to a ton of sub-frame and custom oil pan work because it is so tall and there is no oil pan made for longitudinal fitment. On top of that, to makes things exciting, it is around 1.5" longer than a VR6. You have to get pretty creative with the radiator support, latch and fans to clear the VR as is, making it another 1.5" in length would be hell.

[nefkntym]

I would say either leave the current motor and work with that or swap in a 2.7tt.

All doable, however...

The cost to obtain the motors, ecu, parts, ect plus the labor is going to exceed the cost of simply upgrading the car to a 3.2 A4 or a B7 S4. I'd almost be confident that it'd be cheaper to upgrade to an RS4 as well, rather than sourcing an RS4 V8 and putting it in your A4. Plus, if you upgrade cars you not only get the powertrain, but other options (recaros, brakes, ect). You also will have a more valuable asset, since an S4/RS4 is worth more than an A4 with a motor swap.

If you're going to do a swap, it's gotta be unique with the ability to make a ton of power... 2.7T, VR6T, or SC 3.0T.

Honestly why not tune and mod you 2.0T? If you are stock a simple tune outpowers a 3.2, a K04 upgrade should be as quick as 4.2 V8, and a GT28/30 series turbo would be near RS4 power levels.

The 2.7 would be cheaper than any 4.2

Never said it wasn't doable, just trying to put everything out there. I am quite familiar with the VR swap, I know an I-5 would be that much harder.

Indeed.

1.) 70k is nothing 2.) 3.2?? Really??? and 3.) If you need to ask "how hard" it will be, your not up to it which means paying a shop gobs and gobs of money (on top of the cost of the new motor/tranny) to do it right and tons of down time on what I'm assuming is your DD.

Looking at #2 and #3 lets be realistic. Your not actually going to do any of these crazy aformentioned motor swaps so why even bother asking.

[Ed Gein]

Just chip it. A chipped 2.0 makes more power and torque than a 3.2.

Most sensible advice given in my humble opinion. And as too the point as Ed's post was, there seems to be a hint of truth in it. Go BT and make your car as fast as your wallet can handle.

All this inline 5 turbo talk makes me happy.
Our shop mk1 TT with a 2.5 and a big turbo is for sale.

[Charles.waite]

2.7t or 3.0t. Anything else isn't worth it. Also, as many have shown, its not THAT much work to get it up and running assuming you can do it yourself, or you have gobs of money to pay a shop to do it. Also a LOT of patience....

The engine depends entirely on your budget. How much are you willing to spend, and are you planning on doing any of the wrenching?
