I am amazed to see that Mrs Jeff has let you live, considering your other incomplete projects..... She is a legend

[@khestehave]

Don’t use that engine! It didn’t have any oil in the exhaust! It was bone dry in there. You’ll regret that later...

[@lebojay]

Explain?

[@khestehave]

Love you getting medieval on it. "Can't undo it... Screw it, I'll just cut it!!"

[@bigcus8176]

Amazing that you did it alone and has the patience to make it happen. Well done mate. I’m hooked on this build for sure💪

[@benbrowning8138]

Jeff, Jasewilks mentioning you and your Home Built channel is an amazing compliment, but also shows this is a great project, given how few people made this V8 swap work. Aaron Fincher also did a 4.2L Audi V8 - 986 Booster swap, with some fine audio and handling videos.

[@glennstagg3559]

Fascinating project Jeff. Going to enjoy following this.

golden info about boxter box marrying up to Audi V8 !!!

[@BadlyDubbed]

I was thinking that I couldn't be bothered watching all the bellhousing work - measuring then fabricating adapters etc, then "tadaaa!" Attention span immediately refreshed. That is a beautiful, beautiful thing.

[@nickmassey9104]

These engines are reliable and fast and fit in a number of conversions .I was lucky to look at a 1303 beetle with this engine in with twin turbos boxster box and utilising many VAG parts to fit it in .cant wait for the next episode .nice one Jeff

[@Duaneoca]

Great video, I’m looking forward to seeing what comes next!

[@baxterscientific]

Jeff great video. You are a brave man to choose the most complex pain in the ass motor to maintain and engine swap. Be careful when cutting that close to motor on exhaust pipes. The debris flies up in to the motor and if there is an open valve all that abrasive goes in to combustion chamber. Then you have a bad cylinder in a few weeks. Only with the wheels not with saw. I cannot wait to see the Alfa done!!

[@mndlessdrwer]

If you want to be absolutely insane when building a boosted V8, a lot of V8s have their piston timings such that you can actually run twin-scroll superchargers on each side and get fantastic exhaust scavenging and get even better low and mid-range performance out of your turbochargers since they're able to build boost more consistently. Twin twin-scroll turbos would be a real challenge to fit into that car, but it's a mad build for a V8.

[@holdencaulfield1001]

I need to let you know Jeff: “It’s off the car/engine. Not off of!🙃

[@benbrowning8138]

So happy you are doing the Audi V8 into Boxster / Rockster swap, Jeff! So few have completed the swap, so you will be doing the world a favour! Check out Jase Wilks' Cayman/Audi V8 swap!

[@fredericrike5974]

Alright, I'm sold! As soon as you said "the older version with a timing belt", I had much hope. I've heard the rumor about the trans fit up and I can easily see how much that simplifies the swap. Now for the "minor details". In future, on the AC problem, call Benny up-he has worked some cars in his shop with AC, so I'm thinking he either has or has a mate who has the pump and evacuation gear you would need. And thank you for taking the effort not to just let it blow- it's the kind of decision we've come to expect from you, Jeff! Best to the Missus! She signed on for some "driving lessons" yet?

[@dericknash6127]

Jeff! I'm the kind of guy that is swapping a Japanese engine in a Swedish car and a Toyota engine into a Nissan, but u man are bold!!! I love it!

I’ve heard of swapping the 1.8 turbo from the Audi into a Boxster before, but not the V8. I guess it’s a case of go big or go home. Loving your work.

[@ProfessorOzone]

Man, that Audi was nicer than any of my cars.

[@1one3_Racing]

My new track car will be here soon. I sold my old one to a guy on the south coast so its still around, but I get a fresh build to fix the mistakes in my last build! Considering filming it for KZbin but I suck so hard at narrating and its so much work. No motivation. If I got 20 bucks a week for it, I totally would though! Hope to see you at a track day! I'll race your Porsche.

[@josipperinic1823]

Great idea and man l love the pors and audi v8

[@shelbymccaul6505]

There are some of us who love the older Audis. I have a C5 chassis Allroad. When you need help with the Audi electrical integration, check out Audizine for info. Also, if you undo the upper control arms from the upright you could probably have left the CV axles in the hubs.

[@dra911]

After the last video, I found some information on the marriage of Audi V8s to Boxsters. Can't say I'm surprised that the transmission mating up to the unit is a big deciding factor - that sure saves a bit of work. Should be quite a machine when you're done!

[@Hangin_With_Shane]

Cool swap! I didn't know the trans and engine would just mount right up together. Should make life much easier during this build...ha ha ha! Hopefully I didn't jinx it!

[@garynorman5179]

If anyone can do it successfully it will be you Jeff. So looking forwqard to watching the journey.

[@Rubinho1977]

With all these projects, i thinks there are more than 24h in a Jeff’s day 😋

[@stuartd9741]

If you watch carefully Jeff speeds up just like superman. Lol. That's how he gets so much done.

[@wonderbat9]

So excited!

[@lewiseig5432]

This project looks like a lot of fun, I’ll be following along.....so many questions, I’m curious for a cost summary when you are done, considering the parts off the Audi you could probably sell...looking forward to seeing your fab skills as it relates to fitting this big motor, and all the electrical system mods that will be required. Good stuff.

[@bshusted]

Make sure to replace the coolant pipe in the oil cooler while you have the engine out. A known failure point on these engines and a major pain to do with the engine in place. The aftermarket aluminum version is far superior to the OEM plastic pipe.

[@aceadman]

Oh what the heck, I’ll follow along... 😊👍👍

[@davidcollins9350]

Brilliant, it pays to do your homework!

[@honestpat7789]

The Audi may not be a modern classic, but the roxster is certainly on its way in to that category - so long as Jeff doesn’t remove too many of its vibrant trimmings!

[@rodneynelson3862]

Wow, that was crazy when you just bolted up the boxster transmission to the Audi engine.... Who figure that one out??!! Can't wait to see how this build goes down.

[@juliank911]

Wow, didn't know this was a thing...a cheap Roxster might just be my next toy...I wonder what the Missouri DMV would think...

[@sword7786]

I expected that was the reason you went with the Audi engine. The issue I have seen with this is cooling, but I’m guessing you have already considered that. Looking forward to the content!😊

[@dumyjobby]

make sense why you choose that engine, also i've heard that they are also very reliable

[@RadostinVelchev]

BTW this one has a timing belt but apart of it couple of cam chains with active tensioners which provide a sort of VVT. Those tensioners are notorious to fail.

[@pascaljeske7307]

[@chrisbird2458]

This is going to be fun .🇬🇧

[@dunniss]

Approved!

[@confused47]

Gearbox compatibility, when swapping engines, is a huge deal - as you've found with the Alfarrari, the measurements, modifications and fabrication needed to make a different gearbox fit aren't simple or cheap! I battled for ages on getting the gearbox, flywheel, clutch etc sorted on my Anglia too, because my Mitsubishi engine never had a RWD gearbox! I did think before you announced it that you've gone with the Audi because the engine is in front of the gearbox, and it's got the driveshafts out of the side of the gearbox, which is what you need for the Roxster! /smugface

[@benbrowning8138]

This is a great swap due to the ability to connect the Audi V8 to the Porsche/Audi gearbox. Some legendary swaps in the past, but not many ..

[@donfinch862]

This'll be a bloody interesting build Jeff. I am considering the weight, which you did mention (with no figures :) ). But if it has been done before it must be acceptable. Go Roxster!!!

[@stuartd9741]

I'd suggest there about the same. I believe that Audi V8 is all aluminum so fairly light weight considering..it's a V8. I'd thought an LS would be a little heavier.

[@stuartd9741]

Quick look suggests a stock 2.5 Roxster engine ~ 400lbs LS ~ 460lbs Audi V8 ~400-700 lbs depending on engine size. So very similar.

[@ProjectSupercar]

Yes, the Audi and Porsche gearboxes are interchangeable, I look forward to seeing how this turns out. :)

On a forum I used to frequent, a guy used the same engine in a Lotus Esprit. I'm in.

Wicked! This is going to be good! =D And an LS would have been sooooo boring!

[@worldofrandometry6912]

I think I'd have added lightness to the Audi and used that for the track car but I know nothing. Looking forward to this one.

[@HomeBuiltByJeff]

Not with an AWD slush box

[@mclarenjohnf1]

From watching a couple of LS swaps they are not as easy as they seem it is cheaper to fit another Porsche engine also you need to find a way to stop oil starvation on cornering by modifying the sump some how or it just explodes again.

[@Steve-jq4st]

Good luck with squeezing that engine into the Boxster- it’s very tight even with the original.

[@MuckAAs]

Firstly your amazing. Secondly kids watching just look up thee process first..... wait just watch this video first lol 😂..... wait your reading this which means your whatever..... your amazing dude love this content

[@danandyong6653]

When people say an LS is cheaper, they are talking about the long run. Audi parts, and aftermarket products are ridiculously expensive, not to mention if you have to rebuild it. LS stuff is cheaper and absolutely readily available

[@HomeBuiltByJeff]

Why would I rebuild it, when I can just buy another one for very little ;) Rebuilding any engine is an expensive and time consuming exercise.

[@benbrowning8138]

Another then Jeff knows already: easiest fab job will be a sub frame to connect Audi V8 engine mounting points to the Rockster. The rest of the job will be Hard!

Show the electrical system and ignition well... when reinstall the engine in porsche

[@MrCaprinut]

And Audi, Ford and Volvo is like Lego if you know what parts fit what. The Mondeo ST220 3 litre engine can be be bolted straight to the Jaguar X series all wheel drive box so you can basicly make a 4x4 Mondeo ST220 if you want to. And since the estate rear suspension is based on the X series, you can use Jaguar stuff to make it 4x4. The rear drive Jag box can also be bolted to the ST220 engine which is based on the Jaguar 30 series engine, so you can build a rear drive Capri for exsample with the 3 litre Mondeo engine.. Or with a Jag engine if you want. The Jag engine also came with supercharger. I know there at least one Capri running that Jag 3 litre engine in UK.

Jeff, interesting build, have you considered the weight of the Audi 4.2 liter V8 compared to the Porsche engine and I assume you will be using the Porsche gearbox, what about the power and toque numbers if you are going to race the car. You will need to boost the suspension shocks and springs and as you probably know how rear engined cars a quite taily. Cheers Rob looking forward to both your builds.
