B8 avant engine swap with Chevy LS1 block. Possible?

[ichigoismyhomie]

Been wondering if it's possible to swap LS1 block into my 2012 B8 avant. Ive search the subforum and google search the web but I did not find B8 build for this type of engine swap. I think it would be badass to do it on the B8 avant and make it a sleeper-ish car with a big (or twin) turbo V8 running straight pipe and ethanol injection. Better yet if it's possible to do sequential twin turbo with small turbine for low RPM boost and ramping up to the higher RPM quicker to spool up the bigger turbine.

It might cheaper than getting 3.0T swap to the avant since I really want RS4 avant but it's impossible to get it in the US and I couldn't afford it either. However, getting LS1 block would be less than half of getting S4 3.0T to do similar swap.

Anyone ever hear or seen this type of project on B8 chassis?

I'm 110% it will be more expensive. A couple people (at least one I'm aware of) have done the 3.0 swap before.
LS1 is uncharted territory to the best of my knowledge and fabricating things to work between the two is going to be $$$$

Can't tell if serious or not, but as someone who has done swaps in other vehicles, I'll chime in.

Your LS1 swap is going to cost A LOT more than you expect. Custom engine mounts, suspension (heavy ass motor), custom wiring, custom ecu, getting your original electronics to work (which might never happen), etc., not to mention cutting into your firewall and transmission tunnel to make stuff fit. The list goes on and on. It would realistically cost you less to buy a wrecked S4 and swap out the engine, ecu, and other components than trying to stuff something made for a much larger engine bay into your little avant.

I disagree with the statement it would be that difficult. It would take a lot of work and wiring know how to integrate. But...

A used 3.0t would fit in a v6 car but mounts would be different from a 2.0t

Cost of engines are not gonna be the deciding factor on the swap, complexity of the swap and time will cost most. An oem install of a 3.0t drivetrain would be substantial, where as a hacked up LS welded in mounts and stand alone ecu without communication to can-bus may not be very expensive. At that point you could also drop in a rear drive trans and make the car a nervous wreck of Camaro and Avant.



There are adapters that mate the 01E 6 speed to the Chevy bolt pattern. I would go 01E mainly because is know to be strong, can easily handle between 500 to 600hp+ when driven with respect. to retain Quattro of course, but the newer b8 uses a different trans speed sensor which would effect traction control.

The LS engines weigh about the same as 3.0T iirc. Within 100lbs on front axle is still a lot, but not insurmountable.

HP per pound is dependent on tuning, cams, turbos etc...

I'm not saying that it's impossible, but there is a lot more to a custom swap like this than another vehicle of the same make. While an S4 swap is also by no means easy, the electronic components at least speak the same language, making it so getting things like speedo, traction control, etc. much easier. A standalone computer will get the engine running, but there are A LOT of unknowns. Not to mention the fact that you can use an entire donor S4 salvage and swap over pretty much everything, whereas you won't have that luxury with a crate LS motor.

If people can shoehorn them into a 911 I'm sure it would fit into a B8

Ugh!!! Just no!... Can't be done..

[Dub_prime]

BTW The motor mounts are the same for the 2.0T and 3.0T it's just how they are installed in the crossmember.

Better off trying to fit a 4.2 V8 in my opinion.

Then supercharge and you are good!

Small blocks are not big, I think it would physically fit. But I second the idea that a 3.0T swap (or even an RS engine swap, if you can find one) would be easier because all of the components are as close to plug and play as you can get with a project like this. They were all intended for this chassis, so essentially every thing needed should already be there.

Anything is possible...I put a Chevy small-block V8, with a PowerGlide auto trans into a Triumph TR7.....then threw a supercharger on it.....

just get a used R8..

LS swap into the B7 A4/S4 has been done but they did not retain AWD but I have not heard of a swap into a B8. I have an LS1/T56 swap underway on my 280Z and I have the 3.0T/6MT swap in my B8 Avant. I can assure you that the LS1 swap will be for more work and $ than the 3.0T swap in a B8 and I do not see how you would be able to keep the AWD set up. All of the parts to complete the 3.0 swap exist from Audi which saves lots of time and planning. I have no clue how you would get your gauges to work with the LS engine or if it is even possible. You will likely have a lot more problems getting your car inspected in Cali.with the LS engine.

I have to say this...if you have to ask this question to the forums, you would not be ready for the shit storm that this project would be in any way shape or form. I would want to have a few more swaps under my belt before even attempting to install an engine from another brand altogether, and a better understanding of how true Standalone works, and maybe brush up on my welding skills.

This should be the default response to all of these dumb threads.

I love how the OP hasn't replied 😅 lol

i think the real question is why? why do you want to do it? and as far as input, buy an s4 if you want more power, though with aprs new stage 3 coming out, youll get about the same power as a stage 2 s4 but with better mpgs. if you just want the cool factor, then by all means anything is possible. but its not worth it. you can find a nice b7 s4 avant for under 15k and that has 340hp and keeps the awd.

BUT the 4.2 BHF is the worst thing to suck in the history of all things that suck.

Or this!!.. I always remember Denis tang spent in excess of 80 grand to convert his b8.5 s4 to have the b8.5 rs4 widebody... Didn't even bother to replace the 3.0t engine with the original rs4 4.2 . 80 grand in parts and labor.... Crazy!
