5 Cylinder 944 Build - Part 8 (Porsche 944 07K Swap)

07K Swap Kit: www.ninexengin...
In this weeks episode, we continue work on the VW 07K swapped Porsche 944. Is the Volkswagen 2.5L 5 cylinder a good engine to swap? We get the car back on the dyno and then take it for the first rip!

[@CHRISGr33r]

Even with a crappy mic, that 5 cyl sounds amazaballz

[@BoostBrothersGarage]

Haha thanks!

[@mikhailSRT4]

Wow sounds just like a viper no joke.

[@jkinerk]

Many things to consider here: 1. Although the hp #s may not seem that different from the NA 944, the power delivery is completely different. The modern power curve is light-years beyond the stock Porsche motor. 2. Without any modifications to the rotating assembly, this engine will eventually spin 8,000 rpm at close to 200hp all day long. Again, a major different from the stock 944 motor but using the same displacement. 3. Mike has the prettiest eyes. 4. With head work and modified cams, this could be a 230 wheel hp, 8,000 rpm engine, all day long. 5. If you have custom ECU or tuning work done, Performance Electronics is THE place to go in the Midwest. A real quality shop with not just niche tuners, but real engineers. I've spoken my peace. Godspeed ya'll.

[@BoostBrothersGarage]

Regardless of the dyno numbers the factory engine was 158 crank (when new!) and this should be 220-230 crank when tuning is done. A 30% increase is HUGE! Also, couldn’t agree more with #3 😘

[@curvs4me]

It's freaking amazing! If you know someone in an auto parts store you can look at other tensioners with stiffer springs you could swap into your tensioner. Also find a pulley with guides for sure.

AWESOME i love the sound! I'm wicked jealous.I would love to build a car like that. good job.

[@BoostBrothersGarage]

Thank you!

[@djambrosia]

What an epic sound, congrats!

[@BoostBrothersGarage]

Thanks!

[@ShittyNapkins]

There is something deceptive and effortless about the 07k despite its low power numbers. It just doesn't bog down or need to be wrung like a four cylinder. I took it up to the mountains last summer and made a 10 mile climb on a 3% (or more) grade without trouble. It didn't care if it was in 3rd or 4th. It just went.

[@BoostBrothersGarage]

Smooth linear power for sure!

[@Pixels_And_Petrol]

That engine sounds so damn good

[@E11ven]

That exhaust manifold makes it sound so much better. I have an 08 jetta with custom exhaust and down pipe. It sounds pretty much the same but with that lambo header it gives it alot better tone.

[@BoostBrothersGarage]

That’s with two mufflers on it, you should have heard it with just the resonator haha

[@E11ven]

@@BoostBrothersGarage I'm sure it was an earganism haha I'm going to see if I can custom fit one in my jetta build. Just have to find one for a decent price. Not many Gallardos in the junk yard.

[@met9009]

Hey maybe something to look into, its a bit counter intuitive but having a pulley with a crown with the center larger diameter than the out side helps belts track center. Having edges when they jump will tend to bunch and tear belts too, this is because belts tend to walk to the tightest part of a pulley. I guess goes without saying having good alignment then if the tension is off as well will cause problems. You do have a lot going on details like this really bog the project down. I may be way off base but having metal idler pulleys with a good crown, I would think this would be in a machinist handbook, and maybe a manual tensioner in place of the spring. :D

[@aw614]

I love the flat torque curve it has and am also really curious to see when the power will level off when the belt issues are sorted. VW really restricted that motor from the factory, guess they can't have an n/a motor upstate their 2.0t lol. I'd love to see a built n/a 07k just to hear it scream

[@tomingebrigtsen8976]

IE Motorsports have built these motors to over 300hp NA

[@BoostBrothersGarage]

I REALLY wanted to keep this engine NA and do a 300 hp 9500 rpm build but the boost bug hit me hard

[@tomingebrigtsen8976]

@@BoostBrothersGarage makes sense to me! Boost delivers for the money and output. The only reason an NA build would make sense is if it somehow kept you in a more competitive race class or kept the car more reliable. That and just the preference for power band shape and delivery if the car was breaking or hard to drive with the extra torque. At this stage it's just not apparent how much that will matter. Looking forward to seeing how the cars do as you get deeper into R&D!

[@jerrycaille]

Cool, swap, there is some of those châssis in Europe, light one.

[@natemeehan210]

I've always loved the 944 for as long as I can remember but I've stayed away due to lack of power and not wanting to get into an LS swap this tho is something I would really love I've always loved that 5cyl sound especially turboed and the extra power is just enough for me to really enjoy the car depending on the cost of the kit when it comes out I way end up buying one and a 944

[@BoostBrothersGarage]

Would love to have you join in on the 5 cylinder fun!

[@RaccoonChrist]

I think they would look bad ass on that car

[@MrAudi220]

That sounds so amazing.👍 i almost bought 2 of those engines at my work if i had the cash back then but i let them go.Sadly. I have a audi a3 8p with a manual 2.0tfsi quattro with a BYD edition 30/s3 8p engine swap with a hybrid tte420 turbo and partially forget engine(conrods and race bearings and cnc ported head with supertech valvetrain.It makes 414hp and 545nm on the crank.If my 2.0 tfsiengine was not build i would have dropped a o7k in it since it's the same platform, with any luck my gearbox just bolts on.😅

[@BoostBrothersGarage]

Dang, I bet that’s a blast! My brother had an A3 but never did anything fun with it. The 2.0L has the exact same bolt pattern as the 07K! Make sure to check out our turbo 07K 944 build series if you haven’t already.

[@MrAudi220]

Boost Brothers Garage hey man thanks for the comment, thats nice to hear about that bolt pattern. here's my cars dyno run, kzbin.info/www/bejne/rpPMlK2kntZjnZI my plans if i ever get the funds are to put in some rs3 injectors( now on stock s3 injectors with a 165bar fuel return valve and upgraded hpfp and ttrs lpfp and controller) and swap my hybrid in for a tte480+ or a g25-550 but since it's a street car i like the hybrids power delivery. I was planning on putting a half cage in since i already have recaro buckets and rear seat removed, and some additional weight reduction like the aircon deleted, lighter exhaust etc.I live in Belgium near Zolder and spa is about 1 and a half hour drive from where i live.But unfortunately my project is on hold because i got my medical discharge 4 years ago, i have severe crohns since 2001 and i worked as a mechanic from 2004-2016 until my body collapsed, i only weight 53kg in the end so that was the end of my career unfortunately.But i get my enjoyment in these video's.It's nice to see projects like these.So big thanks for the content and the comment👍✌️👉

[@evancrouch9939]

Haha all 944’s love to throw belts!

[@BoostBrothersGarage]

Bastards!

[@jamest5149]

Try a clutched/one way alternator pulley, allows the alternator to free wheel on engine de-acceleration... should save belts.

[@BoostBrothersGarage]

It’s a harmonics issue with the factory damper. Starts at around 6800 and nearly impossible to fix without switching to a viscous dampner like the TTRS unit

[@333pg333]

Nice work guys. Assuming there are plenty of examples around the world of people building up these motors (in various cars). Therefore what are they doing about the belt issue? The harmonic balancer should help.

[@BoostBrothersGarage]

They are doing the TTRS crank pulley alone and that seems to solve most issues.

[@333pg333]

@@BoostBrothersGarage Great to know there's an easy solution. You'll definitely have to sort it out before going forced induction. Looking forwards to your progress.

[@BoostBrothersGarage]

Thanks!

@@BoostBrothersGarage Just found a guy in Oregon who has a 924 racecar with i5 motor conversion. Look up Britain Smith on FB.

[@sportsmansparadice42]

Two things I would try regarding your belt throwing issues. Under drive the water pump pulley or crankshaft pulley to slow down the belt accessory drive. Second what belts are you using? If it's not Gates or Continental Elite then throw them in the trash.

[@BoostBrothersGarage]

The belt we kept tossing was Dayco because it’s what was in stock locally. I’ll get a Contentinal on order, that’s what belt is on the water pump / alternator etc and it’s great

This is genius

[@andreasvu9540]

Hummm i see this NA version of the build is using a Power steering Pump, I am still wondering if a 2012 2.5L with OEM power steering can be used with the kit... interesting build. I am interested though only secured 2 newer VW project cars...

[@BoostBrothersGarage]

The hydraulic PS pump has to move to make room for the intake. There are ways to still have AC if that is your concern.

[@shaunpc2512]

Although I love the sound of the engine as it is I’d definitely be wanting some boost to wake that thing up. I think it really needs a turbocharger or supercharger, for the difference though I’d love to see it supercharged.

[@BoostBrothersGarage]

Supercharger would certainly be cool but the turbo is the easy button!

[@shaunpc2512]

Oh I absolutely agree, it’s going to be a force to be reckoned with once you get a turbocharger on there.

[@albertgarcia2214]

When will the intake manifold and oil pan be available to purchase?

[@BoostBrothersGarage]

Our goal is to have everything available for the first of the year. We want to get some real testing done to make sure other people don’t have to deal with the headaches we are!

[@curvs4me]

I don't know if it will fit but the rs3/TT uses a different tensioner and steel pulley.

[@BoostBrothersGarage]

Thanks for the info!

[@Jonathan_Doe_]

Bet it feels fast on the butt dyno already with that torque curve, even running 40-50hp down on what it’ll be able to make eventually.

[@BoostBrothersGarage]

HUGE difference from stock. Finally feels like a properly quick car!

[@Jonathan_Doe_]

Boost Brothers Garage Yeah the chassis’s capabilities are totally wasted on the non turbo versions, my mate had one, and you could throw it into corners really hard and maintain your speed pretty well on country roads, but it was just so slow getting up to speed.

[@jet_tin]

how about cog belt like you see on harleys and super chargers

[@YensR]

#fivecylinderisbestcylinder Awesome build man! I drive an "original" Audi 5-cylinder (1990) and the 944 is my favourite Porsche. So of course I subscribed!

[@BoostBrothersGarage]

Thanks for joining us!

[@Gidenkidenk]

The engine that the 944 should have come with

[@BoostBrothersGarage]

Agreed!

[@coronapack]

My experience on mustang dynos- (heart breaker dynos) is they are 30whp under. You probably are sitting right at 200whp.

[@BoostBrothersGarage]

Was 192 on a Dynojet. I think with a bit more tweaking we can hit 200!

[@pacoflyer]

Seems like I found a project car i want to do!

[@BoostBrothersGarage]

It’s a great platform and with the swap it’s a ton of fun!

[@mrrpm246246]

I have questions 1 can the performance electronics ems be used with a race pack iq3, dose the ps relocation kit allow for A/c and will you be producing pully a kit that will help eliminate the issues that you are seeing with the belt

[@BoostBrothersGarage]

ECU uses CAN so any aftermarket race dash plugs right in. We will 100% be offering the pulley solution in our kit. AC could be installed on the passenger side of the engine.

[@christopherkinsman1543]

Any CA peeps starting or finished with this 07K conversion? Any tips on passing smog? Thanks!

[@BoostBrothersGarage]

Discussing with people but there are issues with doing it. The main thing is you have to keep the vacuum pump on the back for he motor which means you have to clearance the firewall or move to an electric vacuum pump if that’s allowed.

[@christopherkinsman1543]

My Bro in law has a LS swap he gets passed smog here all the time. I’ll hit him up for his resources and try and report back so you can pass on to any other CA swappers who need help.

[@Synaps4]

Wait....so a broken belt is now likely to to force you to spend two days pulling the engine out and replacing the 3d printed engine flange every time it happens? Instead of trying to make it never happen it seems better to just design it to handle the failure, right?

[@timweaver9773]

No. The belt broke which spiked the coolant temp, which melted a 3D printed prototype part. Once they figure out that the part will work they will have the actual part cast or machined out of metal and it will never be a problem.

[@BoostBrothersGarage]

Agreed! This failure was just because we were using a plastic 3D printed coolant flange. The production piece will be aluminum so it won’t ever be an issue again.

[@kerryL]

YES 👏👏👏👏👏👏👏👏

[@BoostBrothersGarage]

Persistence pays off lol

[@toad0720]

Wonder what you would do with a complete engine like Integrated Engineering puts together?

[@BoostBrothersGarage]

You mean the crazy NA build? I’m guessing close to $5k. You make quite a bit more power for way cheaper by going turbo. But those NA builds sound amazing and would be a great match for a lightweight 944 track car

[@ShittyNapkins]

Stock cam? Is it using VVT? No matter what, that Gallardo manifold makes it sound better than my '13 Passat.

[@BoostBrothersGarage]

Stock cam for now. It is using VVT but it’s not fully dialed in. We gained 20 hp just through initial VVT tuning but it needs some more dyno time to be perfect

[@NatePrikkel]

The 07K belt problem is also exacerbated by poor quality belts. You need something made with racing in its design. I went through about 10.autozone, etc. Belts but haven't broken a single Continental belt so far

[@BoostBrothersGarage]

Good to know, appreciate it!

[@EatSleepDrive]

She's a screamer.

[@mk2ptslow]

What’s the name of the tensioner pulley company you’re using?

[@BoostBrothersGarage]

We designed and manufacture our own. They will be for sale soon though!

[@mk2ptslow]

Boost Brothers Garage that’s awesome! Please let us know because I will definitely buy one if it fixes the belt issue.

[@BoostBrothersGarage]

Will do! The TTRS balancer fixed the belt issues thus far but I’m running the lipped pulley for piece of mind.

[@toad0720]

This is also a STOCK 07 K motor correct?

[@BoostBrothersGarage]

Besides the intake and exhaust manifolds it is

[@mrrpm246246]

Lolz the car looks about as fast as my vr5 20v golf and that's pushing 189 hp and 166ftlb

[@fadedjate7230]

So how did you fix the timing belt issues?

[@BoostBrothersGarage]

Fixed the accessory belt issue by installing a TTRS crank pulley/dampener and developing a tensioner pulley with a lip to keep the belt from walking.

[@fadedjate7230]

I currently do not own a Porsche 944 but seeing this Five cylinder swap. It gives me dreams of a car that sounds like a Dodge Viper without the big price tag. How much would it cost to do this engine swap.

[@BoostBrothersGarage]

I’ll have about 8k in the NA swap, and another 2k or so in adding the turbo. Good news is engines are $250 so after the initial investment it’s SO much cheapies easier to work on and modify.

[@fadedjate7230]

So I could have a budget Viper for possibly 15,000$. Now I just need to finish my other project car a 1969 Ford Falcon. Don't suppose you guys have a five cylinder kit for one of those? Lol! I will just have to wait till next year and get my Porsche.

[@BoostBrothersGarage]

Love those old Falcons!

[@pepelapew2724]

A stock 944 has 140 to 150 hp .

[@BoostBrothersGarage]

Correct. The 07K in NA form makes about what the 944 turbo does. Our turbo 07K build put down 454 whp.

[@jeremysutton696]

I reckon you should have stuck with the 951 engine, mine made 427bhp with a flat curve!

[@BoostBrothersGarage]

This was never a 951. Sourcing and building a 951 engine would have been more expensive than what I’ll have in the swap once turbo’d. I still have my 2.85 hybrid stroker 951 engine for my widebody car

[@Speedwelltuning]

This a non turbo? Seems pretty slow on the video. Sounds faster than it is lol. Needs a supercharger..

[@BoostBrothersGarage]

Non turbo but it is getting a turbo. We have customers who will be doing the swap as NA and this is the development car for base tune etc. I gained 5.5 seconds a lap from just the engine swap vs the stock engine. 1:31.5 to a 1:26.1

[@Speedwelltuning]

Boost Brothers Garage sounds like a good plan 👍. A fully built n/a with ITBs would be good to see as well

[@ChrisSs85]

Get your face out the video and show me the car
