He Swapped a Twin Turbo V8 and V10 into Audi S4s!

Get ready to witness the ultimate automotive transformation as we delve into the extraordinary world of Martin Harp's engine swaps! We follow Martin's journey as he takes on not one, but two mind-blowing engine swaps that defy all expectations.
V8 Twin Turbo Power Meets Manual Precision!
Martin Harp, the visionary mastermind behind the audacious project of swapping a V8 4.0 twin-turbo engine from an Audi S7 into a B5 Audi S4. But that's not all - he's taken it to the next level by pairing it with a manual transmission, an incredible feat considering the 4.0T V8 engine was never offered with a manual gearbox from the factory. The symphony of power and control is mesmerizing, as the S4 roars to life with the heart of an S7 but the soul of a true enthusiast's manual dream.
V10 Dominance Redefining Performance!
But wait, there's more! Martin's obsession with pushing the boundaries doesn't stop there. Witness as he orchestrates an even more jaw-dropping transformation, transplanting a V10 engine into a different B5 Audi S4 chassis. The spine-tingling growl of the V10 echoes through the streets, delivering a surge of power that redefines what's possible in a classic Audi S4 body. The harmonious marriage of the V10's raw power with the precision of a manual transmission creates an exhilarating driving experience that's second to none.

That Wide body b5 is out of this world. It's pure perfection.

[@thestigseuropeancousin7941]

For real tho, thats gotta be a B5 dreamcar

[@Pigbearman123]

Phillip Kaess RS4 Limo

[@ordersforsplitdogs4315]

Agreed

[@MrEltonArendse]

“I know all the flaws and they stick out to me like a sore thumb” Certified perfectionist right here!

[@jimmytwotimes802]

I can’t believe he was able to cram a V10 in there.

[@DuetchJunger]

Im amazed the v8 fit with factory stuff

[@hopingforthebest1.9]

Especially considering how tight even the v6s are in B5s

[@allanon93]

Watch Joel Franciso part of the Audi C4 group.

[@DuetchJunger]

@@hopingforthebest1.9 got that porsche service postion. Step 1. Remove engine

[@lutha1720]

This is brilliant how much mods to fit a v10 in there. I get the v8 was available on that platform so it could be done.

[@hatadds]

He is amazing. “I would try try things and they would just work”. His ability to visualize, wow.

[@julianmarin5841]

Yeah but most of us dont have extra parts laying around to just "try thing here and there"

[@Edman116]

Motivation, skill, and ability is the answer to most everything. Hell of a build!

[@quintonulm2435]

That 4.0T is hands down the most beautiful, cleanest build I've ever seen in my life. Hats off to this man, what an artist.

[@charlesclairvoyance]

This is by FAR my FAVORITE episode of Deutsche Auto Parts ever, Mr.Harp is a great dude and I absolutely love his builds - glad to see he's getting that recognition

[@josephaction1138]

Yes, he did that for fun, but he also knows the 2.7 fully built with right turbos would be faster than both of those engines🤷🏽‍♂️✔️💯

[@charlesclairvoyance]

Hahaha, I respect that opinion - but I don't believe that Martin did it to be fast but rather to push the envelope of the chassis and inspire others. @@josephaction1138

[@DahakaCL]

This is probably one of my top 5 random guys over the internet. The way he joke around about his skills and builds are just so natural, is like watching a friend talk. Great video, there's so much cool swaps and projects that are hidden gems lke this one

[@Kiss__Kiss]

While people are going to negate my sentiment; This guy is pretty much up there with Porsche's singer. His mastermind is that wild. OEM to the next level(Yes, beyond OEM+).

[@WesM757]

I 100% agree! He could do 4.2, 3.0T, 4.0T swaps!

[@chrisnigro2492]

I love my B5...I dream of someday even attempting a 4.2 swap. This guy is the new B5 God for sure. Amazing work.

[@Afr0m5n]

The B5 Body with the V10 WOW best of both worlds!!!

[@MiGujack3]

Handling left the chat.

[@rdkuffel]

You’re humble. What you’ve done is absolutely incredible. Props!

[@markcollins457]

The fact you down play this swap is the reason i stopped for a double take. Your a true gear head. ****Awsome **** Fresh air fender slots like the Mercedes Diesel would be functional and look cool.

[@gioelegatti4558]

Pure passion and madness too, but as an IT technician who loves mechanic works too, I can only say that those builds are some of the best I’ve ever heard of!

[@andyid26]

ive owned a B5 S4 and did all the work to upgrade and fix it to a RS4 and this is just amazing work and dedication as its not easy!!! My hats off to him!!

[@noaht5191]

Dude is humble, but hes low-key an audi genius, and he knows his stuff. He should be building cars like this for a living. Id love to pick his brain about what kind of swaps and manual trans options i can do in my 02 A8.

[@JoshKoaster]

Martin is a cool guy. Super friendly and extremely helpful in the B5 groups

[@BkSMedia]

The swaps are really cool, but the thing that really intrigues me is the technical and engineering side of things, like solving the CV shaft issues, and sniffing for CANBus signals. Rad!

[@lutha1720]

According to the video it's easier if you get c6 s6 wiring harness to get the engine running instead of using canbus convertors

[@TheCluelessEnthusiast]

That b5 v10 is so cool. Looks awesome, sounds awesome. Perfect combo

[@DirkOz]

Great to see Martin Harp entertaining & informing all of us. B5 Hall of Fame. Greeting from Australia.

[@theassenz]

I have admired this man's work for a long time. Well done, awesome builds!

[@rb26sr]

Oh wow, I'm in love with that widebody 4.0T build! So clean, so simple, but yet quite involved underneath it all. Bravo!

[@YouTubeHandlesAreStupid]

9 dislikes = absolute. jealousy. There's absolutely zero reasons to disrespect this guy; but, they can't control their hate.

[@Red6er]

Glad to see Martin's work getting the attention it deserves. This dude is a mad scientist of Audi's. Been following is work for months. Props man, awesome to see some good vids of this stuff!

[@bradbozarth3235]

Just want to take a second to let you know, this channel is top notch. New Subscriber earned

[@jamerican1]

This guy is a legend.

[@FigureItAudi]

Great feature - thanks for giving Martin a place to share his story!

[@brianchuck9264]

This is not normal, very talented, great work bro...keep it up !!

[@Jagrupra]

I can listen to this guy talk about cars all day, awesome builds 👍🏼

[@conradclaassen1214]

Thanks for putting this together. Great story and wonderful build

[@Anna-op4bs]

"I just kept crawling and it kept working" that's how you put a V8 4.0 twin turbo into a B5. For real these are mind-shatteringly incredible, impeccably done

[@sHpAaKu316]

this is what passion is all about!

[@daytoncorl271]

When I think of Audi enthusiasts, Martin Harp certainly comes to mind. You guys should have Joel Francisco on with his V10 URS6 build after he finishes his twin turbo set up!

[@Deutscheautoparts]

We made a video with Joel linked below would love to check it out again with the turbos! kzbin.info/www/bejne/p2rKhYaXetWEjKM

[@Runneround]

incredible builds. thats exactly 100% my favourite flavour of car enthusiasm. congrats to the builder, I'm in awe.

[@joelfrancisco3798]

Been waiting for an eternity for this! So great to see Martin get the spotlight from Helen!!!

[@DrCrazyAzz]

What a cool dude. Awesome builds. The B5 is timeless.

[@The-truth-is-valuable.]

This is the kind of builds that I like: Clean, underrated, OEM-plus. Factory "look". Very, very, very nice.

[@steelgator412]

Incredibly clean swaps on both. Wow.

[@bigrodrigo1]

beyond cool , great build’s both of them. I get the same sensation with my build (ap 1.8 big turbo daily) great video!

[@THEMOSTHATED203]

My boy Harp gettin some exposure for Our Cars! Both of those builds are insane man

[@deanharriss2029]

Both cars are stunning. Very nice

[@pontimoney2498]

This guy is a legend!!!

[@steveschmidt5574]

I loved every minute of this B5 magic!

[@insaneconqueror5421]

Sick builds. Good video.

[@PokeChu0107]

Both these builds are amazing. I've watched both builds from start to finish. Which is never done really. You and Joel are the top swap fab guys in the Audi community.

[@rosannamussi3132]

You did an amazing job! Very well done 👏👏👏

[@HaltonLax44]

Damn. There are few build videos on KZbin that I will watch from beginning to end and be fully interested in. Most of the time these builds have been done and copied many times. These two builds right here are so unique. Absolutely love the fact that he kept the swaps within the same brand. That V10 is sick. Love the fact that it was rear wheel drive. And that 4.0 V8 swap out of the S7 is just an amazing build. When all of the kinks are worked out, that will be one of the best Audi builds of all time.

[@randomguy4273]

Very cool builds, great stuff!

[@seansmile]

Loved seeing these there !

[@Jonathan_Doe_]

That v8 engines a nightmare lol… At least the timing chains/tensioners between the intake/exhaust cams on the 30v V6’s are vaguely accessible without pulling the engine, and the cambelts at the front.

[@Jackinacox]

I'm sure he couldn't care any less considering the work he's done - now for the rest of us.... yeah

[@Jonathan_Doe_]

@@Jackinacox Yeah but what I’m saying is, just building the S4 engine would’ve been easier, and made great power, with less headaches.

[@Poorschedriver]

Absolutely insane builds. I'm just speechless

[@alanburke76]

Those are great builds! Thank you for sharing these. Certainly gives motivation to others to just get out and do, whatever it is they want to do.

[@johngrundy7197]

Amazing. Well done my dude.

[@backnunAndy]

what a work! Nice job! Nice looking and great power train!

[@teletin01]

😮 incredible ! Amazing job !

[@ZakKol69]

Martin harp is one of my mechanical hero’s. Been following his work for so so long.

[@charlesshamseldin9555]

Great builds, nice owner. Tx for sharing

[@mikaeljonsson4686]

Really beautiful builds!

[@superradada]

WTF the best swap ever!! I love this B6!

[@MustaafaAlazzawi]

Awsome build, humble man, great Knowledge and beautiful cars

[@deeolusanya9325]

Both of these are amazing!

[@kylegrant4303]

hell yeah he is from Iowa! some dream builds!

[@free2chasehappy]

Labor of love! What this guy has made is nothing short of amazing! It is so funny that we are our own worst critics, nothing but respect for this guy.

[@ReydioTube]

Thank you for your service 🖖

[@jorgemendizabal6596]

I Always been a Big fan of this guy, crazy amazing work , Definitely deserves alot more recognition.👏. "The Frankenstein of B5's" 🙌

[@Roddy_Zeh]

It sucks that Audi never made a B5 coupe...would've been even more epic to see this build as such. In any case, I recently found and started following Martin's work and how surprised I was to find this video just uploaded. 😂 Thanks, guys! Awesome work, Martin! Much success to you! 😎👍🏻

[@kristoffer3000]

I've never even thought about that but it would look so damn cool as a coupe.

[@Roddy_Zeh]

​@@kristoffer3000 I've seen a few renditions on the web and it didn't feel right, but I guess it was because the roofline was similar to the sedan. A coupe needs to have a slightly lower roof, windshield with a steeper angle. I don't know if you ever seen, but Audi produced a single A8 D2 Coupe in the 90's, a project co-made with IVM Automotive. A roofline following that design would've been perfect for a B5 Coupe, I think.

[@kristoffer3000]

@@Roddy_Zeh Yeah, I googled it to see if someone had made some renders and none of them looked right, they mostly just removed the rear doors and called it a day. Slapping the first gen A5 roof on it would look great.

[@iseahv]

Been a follower of his work for a while now. I rate him a lot

[@damionatherton7312]

Great work. I love the build

[@leandroonishi5600]

Thanks youtube algorithm for recomending me this. Sick builds and coverage!

[@reaxions]

These are both extremely impressive!!!

[@benahrens8498]

This guys awesome and extremely humble.

[@jayse63amg31]

Awesome build!

[@motheolebelo]

Epic builds Thumbs up Very unique❤

[@PureDriveVibes]

What a craftsmanship, in my opinion this guy is the definition of a carguy

[@WordToMomsYo]

Gorgeous builds.. TWO of them... Great taste, too. All he's missing is a monster 5-cylinder project. 😉 Sometimes the guys who build these things just rub me the wrong way, in which case I wouldn't even pay attention to the video... but he seems like such a decent dude, so I can't help but be happy for the guy for having accomplished some pretty impressive builds.

[@peterrennie5396]

Martin you're the man! Amazing work!❤🤯

[@robertking888]

DUDE those things are so sick!!! Unbelievable you got some skills.

[@sebastianlorenzo4935]

Amazing work.

[@jayt1687]

Unbelievable builds! In the garage on his knees! Props man … PROPS

[@firedustman]

great job man, great job

[@snailedEJ1]

Now, this is quality content!

[@WheatThnis]

this guy is on another level, good job my man.

[@Brandon_Audi]

Yeahhh Martin!! Love it bro you the man!!

[@northwestmountainbikeaddic6874]

Super sick build!!!😮

[@ppppw2]

I could listen to this guy talk audi all day, epic builds omg!

[@MrT-lh1bw]

I love listening to people who have such passion about something doesn’t matter if it’s car stuff or not

[@evangarciavdub2361]

This is sweeet! I’m currently in the middle of a swap myself. I’ve got a MK6 Jetta with a 2.5L + 09G, lol, well, I did, the car is gutted now and I’m putting a 3.6L V6 + DSG in place instead.

[@PapiAndrey]

Are you modifying the engine at all? You rarely see 3.6 VR6’s modified like you do with something like a VQ. They seem to pick up solid power with bolt ons and an e85 tune, would be cool to see an NA VR do the same. That along with rwd conversion would be awesome in the Jetta

[@evangarciavdub2361]

@@PapiAndrey There’s not a lot of love for the 3.6.. lol, minimal aftermarket since people can pull more out of turbo motors. I’m likely just gonna tune it and that’s about it. ..but we know how that goes.. “yeah I’ll leave it like that” < then all of the sudden your car is completely something else >

[@jeremysmith876]

Those are two killer builds!

[@m.pietro9087]

You are a genius. Awesome job. Awesome cars.

[@yellow88si]

This man is my god! Totally underplayed all the lessons learned and trials and tribulations. Its my dream to swap in a V10 but right now I have a 2.7T sitting around that I plan to drop in my B6 A4.

[@in66]

good job man 🤝🏽

[@denalidriven1574]
