Everything You Need to Make 500hp in a B8 Audi A4 

Bought a B8 A4 and the engine blew up 2 months later from faulty piston rings. Just finished replacing the engine myself and it’s running better than ever now! Onto the mods finally!

I'm obsessed with B8's... they look not old but not new. Just the perfect balance of both worlds. Absolutely timeless!

Nice information for the B8 folks out there. It's true what you say about buying an S car and not having to worry about a lot of things. However, all the people I see with heavily modded A3s, 4s and so on really love their vehicles and it's nice to see something different imo.

Yep, i'm like you, i am building up my 2010 A5 S-Line Quattro Sportback. Just got it back from the mechanic, now running it in. She's got forged internals Bar Tek conrods, JE pistons, bored to 83mm, had the head ported, done the front mount, CTS billet PCV and external catch can, HPA alluminium intake, APR coil packs, all intercooler piping done, aswell as diverter valve, turbo muffler delete, 3inch IE dump pipe. Will be going the Boss500 turbo and fuelling and injectors like you mentioned in this video on the hit list. Paying a mechanic for it all, so have to be willing to delve into the wallet indeed, but will be worth it. Have watched all your B8 build videos and looking forward to more. Keep up the great content👍.

As someone who in his younger days built an Eagle Talon with 749Whp and now all into Audi family (cuz it tickles my genes) in my mid-life crisis. This video is so much fun to watch. You're this kind of a dude I could hang with whole day, and that's a lot from an autistic dude lol - After 2014 Q5 TDI (God I love that torque!) Then 2017 3.0T Q7 I landed on well aged 2014 Allroad and it was love at first sight, Ha! Thanks for making the vids and sharing your experience - I'm very much enjoying the watch! 🙃 - BTW I ran JE rods on that build, nice to see they're still around!

Man I really appreciate this video, spent about 30-45 looking for a good video on how to make more power, I don’t have the b8 quite yet but she’ll be here next week. On the topic of s4’s though I owned a 01.5 b5 s4 avant with a 6 speed and as much as I miss how easy it was to build I’m looking forward to getting into a newer platform. It’s comforting to know there’s all the videos you’ve done to help me along my way. Much thanks man!!

One year ago today i bought my stock b8.5 and now it is running a Boss600 kit. Thank you for inspiring us all to build our cars and I have loved and followed your content for a while.

I have an 2011 A4 B8 I'm not even looking for any turbo upgrade or nothing I just wanna get everything you need for stage 2 tune and id be HAPPY, also love your videos keep making the amazing videos

im so lucky to live within 50 miles of IE, they've been so helpful in teaching me and helping me build my b8 a4

I have a 2014 a4 quattro and all I've done is k&n intake and a IE stage 1 and I'm honestly pretty happy with it!

I just got a Audi a4 Quattro sline and bro I can’t lie that shii is quick asf is sport

just got my b8 a4 back in november of last year and I'm currently fixing her up and making sure everything is spec OEM and running great before I throw any mods into it, just about finished with the timing job on it, first car and first timing working on anything but overall I love the car and cannot wait to push more power into her

B8 is the best looking A4 ever build.

🤣 something tells me that you regret not getting an s4. But at least there isn’t that many people who can say that they dismantled an Audi engine and reassembled it all by themselves. (Not once but twice….yikes)

Great! I Enjoy the video production and effort you put into this. So refreshing actually watching a well produced video with valuable information instead of other RU-vid channels that run off their phones! This makes me love my B8 even more. Through all the pain it brings. It’s one day gonna be the little 4 cylinder that could !! Would love to see that build sheet and final price you spent !

Love the content! You hit the nail on the head, my 11’ 6MT has a special place in my heart and I can’t part ways with it. Although I have my eyes on a special edition b8.5 s4, the a4 ain’t going anywhere. You’ve inspired myself and many others and I thank you for that as well as all the great information you supply! Hoping I can get my build going and run into you at gridlife or another Midwest meet in the near future!

i'll never buy an audi but i still enjoyed this video. it's nice to fully get into what went into this build

"If you're not comfortable doing it yourself, go to a professional" should be said in EVERY DIY car video. Too many people destroy cars with jank installs

I was getting my first car and seen a cheap audi with 130k miles and it so happened to be a 2010 a4. Got in the car to test it and was absolutely blown away to hear a turbo spool😂 was sold instantly

I love my 2010 a4 ngl , can’t wait to upgrade that 2.0!!

I got a b7 a4 for free with 150k miles on it. I’m planning on doing something fun with it. This video is gonna help me

Great video Chris! Yup, building a big power B8 A4 is a money pit, but like you, I wouldn't change anything. :)

This type of a4 is very beautiful. thanks

You made the start of my day even better. New episode to watch thanks flink

Thank you for paving the way for the Audi A4 B8 2.0t engine

Dope! I still haven't understood if an in tank pump is needed for a BOSS600 or if a larger throttle body has any real gains or not. These cars are still a blast. I really like my A4. I mean the S4 is cool but there is nothing like a boosted AWD 4 cylinder.

Great video. I really love how honest you are about additional costs and potential alternative (S4). I got A5 with same 2.0 tfsi CDNC (211hp stock) currently running K04-64 hybrid with big IC, custom active exhaust, downpipe, intake mod, S3 injectors and autotech hpfp. I was thinking about going next stage, but 370hp with flat 500Nm works great as a daily so far. I'm both worried about costs and ability to drive a car as a daily. I guess for the moment I am good, doing times like RS5 in heavier 2.0 sportback.

When it comes to modifying your car, there is no budget. You will never be satisfied and always have new ideas.

Really enjoyed this video 📹. I went with the N/A V8 RS5 but I can see how your car would be much more fun. A 500HP 4 cylinder is a Beast. NICE JOB......🚀

Lots of options. I’ve a 2012 2.0 Avant that I purchased new. Since buying the car I’ve invested nearly 85k, ( including purchase price) Rings and pistons replaced at 55k due to oil consumption issues. Engine failed again at 67k, I bought a new long block from Audi in March of this year. This car had Stasis sway bars installed years ago, I’ve added a CTS K04, CTS intake, CTS intercooler, cat back exhaust, down pipe, IE aluminum manifold, IE catch can, Bilsteen coil overs. Needless to say, it gets up and goes. Not as good as my TTRS though.😂

Always a good day when you upload

Yasss I was waiting for more videos on the B8 since I’m doing almost the same thing 🥴, my turbo is going in this Tuesday and I’m tuning my car with Tyler

For us average joes I would say take this to a high performance Porsche shop. You are lucky to have enough mechanic experience, but I’ve found that even for some standard maintenance, I get the best service, advice and real world experience from my local high performance Porsche shop. It’s all VW parts. Also seen some guys steal Macan parts and swap them onto their A4 or S4 and also Gulf GTI

Great video and given me food for thought. I have a standard S5 B8.5 Coupe and am currently at the ‘homework’ stage. Plenty of folk who know my plans keep telling me to “just get an RS5, it’ll be cheaper!” but they don’t get it. I want my car, modded my way with my blood, sweat and tears (and overdraft! 😬). I have a 2021 Mustang Mach 1 (that I won in an online raffle 😊) which I’m about to sell and that’ll free up quite a bit of money to put into the S5 so it’s going to be a well sorted car 😎 (the Mustang has loads of ‘presence’ but the S5 is still much more fun, even in standard guise!). I appreciate that you’ve gone ‘A4 to better than a S4’, well I’m hoping to follow the same principal but ‘S5 to better than an RS5’ 🤞. Thanks for the motivation!!

your really inspiring me on my current journey right now with my B8 A5 2.0 6spd. Literally the only thing really scaring me is the rings and oil consupmtion.

been looking for this exact video for ever. i got no idea what im doing so this helps a ton

As a fbo s4 owner this makes my heart happy I always loved the vw cc 2.0k04 I had and planned to make big turbo but it got wrecked. I always hated the traction issues I had with front wheel drive so I about bout an a4 but the b9 barely gets support and I got lucky and found mine ! Love turbo cars miss mine but love my s4

I was actually thinking of doing my Audi but after watching two minutes of this video you convinced me to get rid of it 😆 thank you 😁

I am currently building my 04 A6 2.7 twin ko4 upgrading to 52 lb injectors it's all in the works right now

Thank you, thank you, thank you! 🙏 I’ve been watching your journey over the years and am actually building my B8.5 A4 right now. Similar to you, I pretty much have most every bolt-on part you can think of. I’m now ready for that next step. Just got my HP Tuners dongle (for Tyler’s tune), IE intake manifold, Grams 70mm throttle body and now waiting on IE rods, Mahle pistons, etc. (the remaining engine build parts) from Integrated Engineering. I currently have an APR K04 and will do Tyler’s K04 tune for now, but by next summer, will upgrade to BOSS500 and MK7R injectors and get a short shift kit. Chris, if you read this, curious to know why you went JE Pistons over Mahle? Again, many thanks for sharing your knowledge with guys like me who wouldn’t have gotten as far or even attempted anything other than a Stage 2! 💯

I have a4 b7 quattro with BUL-engine. Stock 220hp. A little tune and now it's 265hp. It's a good daily driver.

I fell in love with my buddy’s a4 even tho he told me not too. Then fell even harder for the avant.

Disclaimer to anyone buying the Rev9 intercooler: It does not just bolt up. You need to fabricate brackets for this intercooler. I tried installing mine when I realized there was nowhere to mount it. Ended up returning it and just keeping my stock intercooler.

The best part at the end is get an S4 ! Great video keep up the good work. Screwing shit up and how we learn and of course it comes at a cost

Love this I have the b9 s5 and i can see a very good reason for doing this and that is to have a manual car as s4/s5 are autos but then if you start with an s4/5 and do similar stuff your way up there in supercar territory great build though its amazing how attached we get to our cars.

Your video is an awesome put together video!

I love this guy, love the build! 👍😎

Great video, dear friend, keep it up, really professional, your car looks amazing and the whole construction is also really professional

we need more youtubers like you

First: I respect the honesty here. Lots of good information too. Second: I have been driving a b8.5 allroad (2.0) for many many years. It’s nearly stock and has been the most reliable car I’ve ever owned (currently over 140k miles) but…Id be nice to have more power. That being said, with cost in mind, wouldn’t a motor swap be a better option? Regardless, great video!

Was a gread video, blew up my dreams of taking my TDI to that level :))...... Guess I'm sticking to that 190 hp stock + 30 rebuilt and remapped for the police :)).... I've done the deal for 3 cars back in the day when rally cars were custom built for everybody out of what you could find.....not the factory tech new ones ......

Boss600 has entered the chat.

For most that aren't mechanics it makes more sense to pony up the dough and get an S4 with a tune and pulley..

Great vid! It’s always greener on the other side. You know my S4 and I’m now considering a 4.0t.

I love you man i enjoy driving my b8 and watching you

The man is absolutely correct, it costs a lot of money to make more power on a car that doesn't have big power. It cost me over $25K to get my mk7 gti from 210hp to 400whp. That's not including a couple of clutches that I went through because of a bad installation and one that I didn't know about the breakin. It didn't help that my EX mechanic didn't tell me about the breakin hence EX and doesn't work on my car anymore. Should I've bought the Golf R instead? Maybe, but then I wouldn't have gain all the experience from going through everything. My car is such a joy to drive even though I get 300km from an $80 tank of gas. To everyone out there that's in the same boat as me, get yourself a membership to CAA (in Canada) or AAA. The best yearly membership you'll spend hands down. Try to do some of the work yourself European car mechanics are expensive. Remember jobs that takes a mechanic 5-6 hrs might take you 2 times longer maybe more. So weigh out the time that it might take you to do the job and see is it worth your time.

That looked absolutely amazing, love your expressions and the "I regret a lot of sh#t I done face" But loving a car is nice.. I am now saving money for a A4 Avant B9 with 150HP 35TFSI. It will go to 235 to 245HP with stage 1 chipping only

If you're dumb and stubborn like me 😆 that's me my guy. Before I bought an S4 I bought a vw CC R line. Despite knowing that it was the worst vw platform to mod (vs gti, a4, S4, etc) I still wanted it because big MANUAL sedan that in my opinion looks fantastic. My car buddy thought I was nuts to try modding it but I still threw stage 1 and some parts into it before it got totaled.

Chris this build has me almost at the next step on my audi build myself! Ive got every bolt on needed for the Boss500, curious how much boost youre running to get 420whp and if whatever it is at, do you feel confident that the newly built engine can sustain it safely and not worry about blowing more parts up? Thanks brotha!!!

Nice video and good info awesomely put together and presented. Well done nice looking B8. It won’t be fun to by S4, but turning an A4 to one is way more fun!

Was looking forward to this vid thanks bro

why cant u b making build guides like this for the RS5, this is amazing

My buddy is a welder and I'm a detailer we do our jobs for eachother for free and damn am I excited to get him working on my car.

Good video. I like the last line you said. I have an s5 but still great info.

At around 3:04, you can hear the sound of your car...so good! What parts are you running? CAI? Diverter valve? TMD?

Giving out this info for free should be a crime but since it's not thank you!

honestly the best bang for the buck is to get a 3.0 TDI, I have mine with stage 1 tune for 310hp

I love the dedication

I was gonna get a subaru brz but i like the audi a4 and s4 dont care which one because their engines can handle nice turbo kits

Awesome video, awesome car. Appreciate the quality.

incredible job! well done bro ! thanks for sharing

taurus sho, 19k used. A tune, thats all for 400+ whp thanks for watching

Fantastic video. Thanks for sharing alll this knowledge!

Man doesn't lie!

How much horse power can I get with a 401k tune?

I was looking into the a4 instead of an s3 as theyre cheaper but you scared me off at about 3mins in, great video though, you got a like 😅

Great video man! Thank you!

Great video.. Vin Diesel reference at 11:56… 😁😁

Love the dedication to the platform but couldn't you swap a 3.0tfsi engine into that for cheaper than the whole build?

I bought a 2012 BMW 650 I one owner with the best warranty I could get had engine problems only had 70,000 miles on it the warranty company replace the engine with a brand new motor the motor came from BMW it had nine updates over the original and 63 Cai front facing intake with charge pipes from freezing intake diners/muffler in Resley with an ex pipe I am about 21000 invested fully which I think it’s dirt cheap and I’m making close to 500 whp

This is great info for my b7

A girdle might be an idea if you want the bottom end to stay in shape

I looove the honesty

I'm glad I went with the s4

This is great, can you do one for the B7 A4? 😁😁

Buoy 😅 you got yourself a new subscriber 🙂🤟💪

Urotuning has some good shit too

The last line is where I understand completely haha. To dump money into something to make the Hp of the next level car sucks. But it’s the pride in knowing you’ve built a 4 cylinder to match the hp of a supercharged v6. Well for me at least :-) Also any idea if APR will send an updated version of the tune if you upgrade to S3 injectors and upgrade fuel pump piston? I’m at that point where I’ve had my k04 for a couple years now, and want to make another step higher. I’ve just recently upgrade all the internals, so that’s already out of the way at least.

Enjoyed the video, makes me excited for my own car, I have a 1.8tfsi 1st Gen ea888 and I’m still trying to figure out if I can buy a turbo and manifold for the 2.0 ea888 and bolt straight in. I can’t find anywhere if the manifold is different between the 1.8 and 2.0. Especially when so many turbos online say 1.8 & 2.0, however when I read what engine codes it would fit it never shows mine - CABB.

Love your build brother… Would you consider closed filter like ECS Kohlefaser Luft-Technik intake? Just wondering if with open cone CAI, do you suffer from heat soak? Also, can BOSS500 handle 550-560 crank hp?

l might just put an N54 on my b8 just because l love the B8 body more than the BMW😭

Dumb and stubborn right here as well - love my slightly modded stage 2 b8 manual A4 currently pushing 400 thousand kilometers. But I have to point out that people choose highly moddable (not sure if that's a word) cars because they are moddable and true tuners love the challenge and the high comes from the accomplishment. Let's face it, you can buy a ton of fast cars for less than 30k. But where is the accomplishment in that? I've done as many things as I can with my hands from mods to my car to renovations to my current and previous homes to building furniture and each and every time I felt like a million bucks. That feeling when you step back and look at your work and can say "I did that" is a feeling that can't be bought. I mean, just listen to the amount of warnings you give on these videos - practically every sentence was a hard earned and well earned lesson. Who cares if the lesson is something that is not super useful for many other applications, the more you learn the more you grow.

I love different. I’m one of those dumb guy who spends a crap load of $ modding something that most ppl don’t like my 600 plus whp BMW 328i & now my Audi B8 A4 S-Line. I’m doing the same thing . I did over size valve/ brass guides, CTs intake & about to order a meth kit for the port of infection, 3angle valve spring, match port & polish on the intake & exhaust’s, over sized mahle pistons & IE rods & dual springs. I also have the crank knife edge balance & polish. CTs FMIC. Labor on the motor without parts cost me over 5k not including parts 😅😅😅

Love that last bit, yeah your not kidding; but the A4 is a lot better balanced car as far as being nose heavy... However, no one cares LOL nice video dude, thanks!

So I have a question about the clutch. With upgrading the clutch, will that help the pedal feel? I have a '15 S4 (stock) and I've always hated the pedal feel. I prefer a stiffer clutch pedal, like a 2000 Wrangler and wondering if there is anyway I can improve that. I am hoping to also Stage 1 tune with a few bolt on's at some point in the future. Great video and explanation.

i dont really want to build the whole engine. I want something that I can do with stock internals at least. I don't want to blow my piston rings like I did in the GTI. Can you make a video about stock internals and power gains?

Why not get the 3.0 TFSI? I mean if its about the building itself fine but power wise the 3.0 TFSI is a far better option. Small upgrades, 420+ HP. If you start investing a bit of money you get a beast.

I've skimmed thru the other videos as well as this, what did you do with the exhaust system? Are you running stock exhaust cat with that sort of power?

A4 B8 Stage 2 APR non Quattro. Fun. But I need those 500 ponies. 😂

Im currently building a sleeper b9 a4, currently at around 320 hp (got intercooler and stage 2 tune incoming)
