Anyone on this forum done this swap. I threw a rod through my block and highly considering it. I would like to hear first hand knowledge not what people have heard thank you

i think it's pretty safe to say that no one in this area has done this swap.

I know some guys in Alberta did an RS4 motor into a B6.

If your heart isn't set on keeping the B5 A4, you may want to consider shopping around for a B6 S4 if you are considering dropping the kind of coin it would take to do a swap of that nature. Another popular swap would be a VR swap, could even do a VR-T, would be pretty awesome.

From what I have read the vr6 swap is a hassle compared seeing as I'm already dbw. And I'm gonna part out my big turbo 1.8 set up to acquire the parts. Right now I have a car with no motor so I can't really sell it to put towards a new car. So I figured I might as well try something new haha

AZ or AW is going to be a better place to look for info.  Once you wade through the "OMG, just do a 2.7T so you can boost it through the ass" responses you'll find a couple guys in the B5 section who have done the swap.  It's very tight though, small engine bay.  I love the 4.2, hell I'm on my second one now, but in a B5 a 2.7T might be the better option since you'll have the chance to do all the engine maintenance before the engine is installed.  Less custom work and it's an application the B5 platform got from the factory.

RS4 into a b6 makes sense since the s4 is already a V8.

Personally I think you might have more fun with a BUILT 2.7T

sure as hell cheaper/easier to drag power out of than the 4.2. Lots of good 4.2 development out there from a few companies but it definitely is a bring money type of situation with that motor. I agree with the 2.7T option as well.

Depends on what you're going after.  If you want a motor to use as a base for a huge power build then of course the 4.2 (or pretty much any NA engine) is the wrong choice.  If you don't want to mod the engine the 4.2L beats the 2.7T hands down in every aspect except fuel consumption.

I'm not overly worried about power. Really love the sound of the v8. Don't overly care about gas. And wanna try the all motor.

lol, you say that now.... come back and talk to me when you've pulled up next to an H2 at a light and thought yourself "hmm... that's a remarkably fuel efficient vehicle".  :rofl:

Yeah true but a built 2.7tt would go through gas quite badly aswell I would think

2.7T would allow you to stay off boost in daily driving which would burn a lot less.  4.2L you're consuming a lot even on light throttle.  I average about 10mpg in my S6 if I'm driving on 100% surface.  That improves to about 15mpg if it's a mix of surface and freeway.  19mpg is the best I've ever seen and that was cruising the I5 to Seattle.

The A4 is alot smaller and would get slightly better mileage if it's setup and running properly. The 2.7TT can be an absolute pig on fuel if not set up properly aswell

Alright I think I'm gonna end up going with a 2.7t. I know everyone will say to sell mine and just buy one but my car has no motor right now anyway so I could part it out or just do the swap either way I'm sitting on a b5 shell for a while plus I just did a wide body rear end and matte lava grey paint. So if anyone need big turbo 1.8t parts I will be making a part out list shortly.

The 2.7tt actually sounds pretty ridiculous with exhaust/intake, too.
