What It's Like Driving a Built Motor Big Turbo 800 HP Audi RS3!!

The Audi RS3 is a very cool turbocharged 5 cylinder engine sedan! However, this particular Audi RS3 has a built motor with a turbo upgrade and runs on E85 Flex Fuel pushing 800 horsepower! This built Audi RS3 makes fast cars like FBO Nissan GTR's look not so fast... In todays video I drive this awesome Audi RS3 and see what a highly modified RS3 is like! I am blown away with just how fast the RS3 is! It is a blast to drive and still retains the fun handling and characteristics people love about a stock RS3. The owner did all the work himself from pulling the engine to upgrade the internals, to adding a larger turbo and complete fuel system upgrade. The DSG transmission handles the power so well and just needed upgraded clutches. Super quick shifts and the power band is endless up to nearly 8k RPM. I loved just how fast this 800 HP RS3 was and it just plants you in the seat!! I have a brand new Audi RS3 on order for late next year, and the owner of this RS3 has a new one coming early next year! Love the Audi RS3 platform and these cars can seriously turn into supercar killers! Gives me some inspiration to continue building my Audi S3 in the meantime! 800 horsepower Audi RS3 is an amazing car and pulls so hard! The race clip of the RS3 vs GTR was not my car. However it was a full bolt on R35. Would be interesting how my FBO Flex Fuel GTR would do compared! But the RS3 definitely puts harder and has a quicker transmission.
Thanks to @inline_five for letting me film the RS3!

Nice video, came across it and the RS3 is the perfect daily. I have an original 93 S4 aka URS4 with the AAN 5cyl 20vt. Thank god Audi never ditched the 5cyl. Look how many people love it. They should offer it in more vehicles. I’ll have an RS3 next to my old beast on day

[@bigboyskaters123]

Thank you for the in depth review and taking care of her💪 hopefully we’ll get some mods on your incoming rs3👍

Dude no way! My brother has a built 2018 RS3 with 700HP currently. If you ever want to review it let me know and I can see what I can do! I've ridden in it quite a few times and it's one of the best sounding cars out there. It's an insanely fast car. It's unbelievable the RS3 only has 5 cylinders

[@BrosFOURRSpeed]

Oh that's awesoem! Message us on Instagram for sure if you're local! These things are so cool!

@@BrosFOURRSpeed absolutely

[@disaster6467]

upgrade the turbos in your Gtr, it usually gives you 850whp on average on e85, around 700whp on 93oct, thats with keeping torque below 650wtq, that the goal for mine lol

[@BrosFOURRSpeed]

Yeah that'd be the next way to go for the car to make it crazy! I've exhausted the affordable mods lol

[@hlf_coder6272]

I took delivery of one of the new ones a couple months ago. It's a quick little car. I traded in an M2 Comp for it. The RS3 is definitely faster off the line, although from a 30 or 40 MPH rolling start, I'm not so sure. The M2 felt a bit more torquey in that range. Overall I prefer the RS3, but I definitely miss the clutch in the M2. The RS3 would be quite a bit better with a manual transmission.

[@justsomerandomguyman]

It wouldn't hold as much power or shift as fast with a manual.

[@VuBeClan]

this is about a car thats holding 30psi and your comparing it to a M2? lmao

[@kbw.rvwhntr]

By looking at this RS3 I would have never imagined one built to where it could smoke your GTR! I bet he put a ton of money to get this up to 800 horses.

[@BrosFOURRSpeed]

Looks to be around a $20k build. Not too bad considering it’ll smoke cars that are over 6 figures. Fantastic car!

[@joshpetit44]

@@BrosFOURRSpeed that’s without labor I’m assuming

[@BrosFOURRSpeed]

@@joshpetit44 I’m not sure. The owner did all the work himself. I work on my cars too so I have no clue what labor would cost lol

You should use i485 to test the cars

[@G.C.502BusFan]

sad to say the 5 cylinder is going by the wayside. there were only a few vehicles that offered the 5 cylinder. the older model freightliner/dodge/mercedes sprinter. the 2015-19 ford transit diesel. the 2007-11 chevrolet Colorado GMC canyon midsize truck twins. the 2013-17 VW beetle its bore bore range was from as small is 2.5-3.2 Liters and either ran on diesel or gas. rhe ford Focus RS that was sold in europe, australia, and other markets before the global RS had a 5 cylinder too

[@BrosFOURRSpeed]

Yeah a 5 cylinder engine is not too popular. We just bought a 2024 RS3. Cool to have the 5 cylinder tho!

[@G.C.502BusFan]

@@BrosFOURRSpeed yeah the 5 cylimder has always been the odd ome out, but luckily it has stood the test of time. Sometimes its better to be the odd one out #beingoddmakesyoucool

[@disaster6467]

before buying my 2nd GT-R i thought of buying a rs3 instead, but i just couldnt do it , theyre great cars but still not an r35

[@BrosFOURRSpeed]

Oh for sure, the GTR is such a special car! But awesome to see how a more refined and less expensive car can be built up just as fast as GTR's

[@sameftek9799]

That intake sucks a good amount of heat no? Great built though.

[@BrosFOURRSpeed]

Probably doesnt matter too much since the intercooler is efficient.

[@bmw_f3692]

DAZA?

[@MatthewJay80]

Yup!

[@CEOLISSS]

In competition form, the RS3 weighs significantly lighter than a GTR. 3200 vs 4000 pounds.

[@BrosFOURRSpeed]

RS3 weighs 3,638 pounds and the R35 weighs 3,800 pounds. Very similar. However the 6in shorter wheelbase and slightly lighter weight in the RS3 makes it much more nimble. Where dod you get your weight numbers form?

[@CEOLISSS]

@@BrosFOURRSpeed 3200 gutted/soaking wet . That's why i said "competition" trim. mqb's are economy cars after all!

[@BrosFOURRSpeed]

@@CEOLISSS Ok well I’m driving a road car. The curb weight is what 99% of people are interested in. But wouldn’t a GTR weigh less then it’s curb weight if it was stripped out too? Either way the R35 isn’t 800 pounds more
