Turbo 07K Build - Part 4 (Porsche 944 5 Cylinder Swap)

[@davidcantrell5098]

Excellent.. I'll be Cerakoting my 944 exhaust manifolds now...

[@BoostBrothersGarage]

It’s fantastic!

[@paulhoffman1481]

Can't wait to see in on the dyno!

[@BoostBrothersGarage]

Same here! Getting super anxious

[@paulhoffman1481]

@@BoostBrothersGarage Forgot to ask you guys, do i need the clutch assembly off the 944 turbo s? Its the aor clutch/transmission so apparently the clutch is beefier.

[@BoostBrothersGarage]

No sir, that clutch will not work with the swap. The swap converts the car to push type hydraulic throw out bearing instead of the factory pull type.

[@paulhoffman1481]

@@BoostBrothersGarage ok awesome! Also will i need the turbo s driveshaft between the clutch and transmission or will my 1983 n/a one be just as strong? Also will it fit?

[@BoostBrothersGarage]

Your NA one will work fine, and they are all the same strength. The only reason to get that torque tube is if the bearings are shot in your existing one. I haven’t come across one with bad bearings yet though.

The Cerakote came out looking pretty damn crispy!

[@BoostBrothersGarage]

Thanks dude

[@robertpaupard1265]

I'm looking for a turbo manifold for my transverse mounted 07k. I currently have a Mk5 Rabbit, but my very first car was a 944! I want to do a build like yours. I love watching your videos- a lot of great info and really cool cars. I learn a lot and it's fun.

[@BoostBrothersGarage]

Thanks! Will the IE intake work for you?

[@robertpaupard1265]

@@BoostBrothersGarage I want to boost my car eventually, but am not finding a turbo exhaust manifold other than the stock Audi TTRS, RS3 turbo exhaust manifolds- Very Pricey!!

[@robertpaupard1265]

I like the SPA log style manifold but they are sold out

[@robertpaupard1265]

@@BoostBrothersGarage Sorry, did you mean you have an IE intake for the 07k for sale?!

[@P1983sche]

Good stuff. Glad I found this channel. Cool builds and great advice.

[@BoostBrothersGarage]

Thanks!

[@kerryL]

That looks great. Hoping the performance benefits show well too!

[@BoostBrothersGarage]

Thanks!

[@jamest5149]

Blocking the intercooler with the oil cooler is a good idea... intercoolers need the biggest temperature difference to work... you will end up heating the cooling air to oil temp very quickly and have very high IAT’s.

[@BoostBrothersGarage]

Hasn’t been an issue so far. We are data logging everything and can make changes if need be. This was a common comment but in the real world it’s not as big of an issue as people think.

[@charliegirl8939]

Absolutely brilliant! Would have never thought to use cerakote on a header.

[@BoostBrothersGarage]

All my research showed it working really well. Time will tell!

[@toad0720]

Waiting for a complete supply list. And a winning lottery ticket to do my 944.

@@BoostBrothersGarage thank you very appreciated.

Great video! I was going to send some exhaust tubing off to get cerakoted... but now I just might do it myself.

[@BoostBrothersGarage]

Thanks! If I can do it you DEFINITELY can

[@gnrrpreacher]

Looks great! Keep pushing for the dyno!!!

[@BoostBrothersGarage]

Thanks!

[@rodolfocastelobranco1082]

Hi, what are the turbo settings? Measurements and Brand? Congrats on the project, thank you.

[@moutinhoandroid]

2 years after...how is it holding (the cerakote) ? Another quick one... Those titanium studs are 40mm long ?

[@bryantward677]

Lovin that shirt, 917k I am guessing.

[@DeancentGarage]

Great vid, keep em coming! I've gotta try this Cerakote myself..

[@BoostBrothersGarage]

Thanks! I’m super impressed with it so far.

[@johnkodera9926]

Sorry I haven’t been fully keeping up, but what cast iron manifold is that from? Is it an oem part from another car?

[@BoostBrothersGarage]

SPA 07K Turbo Manifold

[@iggyneuschaefer7131]

Now you just need to get some coatings inside that Cayman 👍

[@BoostBrothersGarage]

I’m gonna be honest, as addicting as this is I might cerakote the exterior haha

[@Kaz73MGB]

So are the stock exhaust studs long enough for the turbo manifold? I'm guessing not, but in that case, what are the specs, or does the manifold come with the bolts? Thanks.

[@BoostBrothersGarage]

Here you go: (15) M8x1.25mm x 45mm. We use a titanium stud kit designed for a Powerstroke Diesel that's sold on Amazon. www.amazon.com/dp/B081J54SB6/?coliid=IG2BUPB9N97RE&colid=232C84B75QSJ7&psc=1&ref_=lv_ov_lig_dp_it

[@Kaz73MGB]

@@BoostBrothersGarage Thanks. Of course it figures they're half the cost of the engine! Such is the swap life.

[@911engineguy]

So, the cerakote doesn't need to be baked in an oven? just air dried?

[@BoostBrothersGarage]

This particular series, yep! I think the oven cure has more color options but you also have to use activator etc. Whatever you mix you use or loose, with this I just poured it back in the container!

[@rickyvwt]

What type of EFI you will be using? I hope you guys make good relyable power on that settup keep up guys!

[@BoostBrothersGarage]

Thanks! We are running the PE3-8400 standalone unit from Performance Electronics

[@kluupom]

How much power are you looking for? AND do you have a motor with forged or casted crank?

[@BoostBrothersGarage]

This one has a cast crank. 400 wheel To start, until we build the bottom end

What do you mean? The TTRS crank when we build it?

[@toad0720]

@@BoostBrothersGarage I meant getting the TTRS crank when I do mine.

[@TheChris360]

when we gonna see some more 07k content ?

[@BoostBrothersGarage]

Hopefully soon. We had to move the turbo car from the shop to Alan’s house so that he could still work on it while we are guaranteed. It will obviously be difficult for me to get over there to film but I’m going to try.

[@KarelBeelaertsvanBlokland]

Is the turbo mounted not too small?

[@BoostBrothersGarage]

Shouldn’t be, no. Garrett sized It for Alan. It’s a 660hp capable turbo. The G-Series are just really small turbos for their claimed output.

[@BoostBrothersGarage]

Hahaha, my man!

[@curvs4me]

Alright bud, I'm ready to make the move. The Audi TFSI head is $4,400 used, so somebody is buying them for a lot of money. I discovered the other link in the detuning of the 07k, they put tiny intake valves in it. Usually the turbo rendition may have smaller valves to avoid cracking. Not this time, Audi has 34mm intake valves and 28mm exhaust. VW has teeny 32mm that can't breathe coupled with 190 duration, like Grampas 472 Cadillac lmao. The exhaust is the same 28mm. Anyway, I am attempting to get two head variations made with better flow than the Audi. I will have to include camshafts because I'm not going to let meatballs give it a bad name running 1987 Mercury Topaz camshafts in purpose built heads. CatCams makes a pretty decent set that I'd accept for stage 1 hydraulic 8200rpm. For stage 2 I'm spec'ing my own 9300 rpm solid roller. If I can't find adjustable lifters, I'll make them. DTM makes exactly what I want for the 4g63, shims or lash caps, no chance. It's more expensive than I planned but more than doubles the power for stage 1 NA. Stage two is over 400 wheel NA. Do you think people will spend $3,800 on the stage 1? I have to do everything, all 20 seats, oversize 10 valves for stage 1, springs, caps, and retainers, as well as camshafts. Stage 2 is 20 oversize race valves, likely titanium intakes with modifications and custom cams with 14-16mm lift race springs and titanium locks to be able to spin 9300+ reliably. Likely 5500 bucks. I'm hesitant to do it, on the other hand all the euro tuners charge over $4,000 just for porting. Do you think people would spend that for twice the power or more?

[@BoostBrothersGarage]

It sounds awesome, for sure. I know there would be people interested but I can’t imagine it being a big seller. Most people will just throw a turbo on and make the 400 whp limit of the stock short block. There are some guys who race in classes that have displacement requirements that might be interested, and those who are just going all out on a build. I would guess you would move a handful a year?

[@curvs4me]

@@BoostBrothersGarage That's what scares me. It's a risk for sure. They are paying huge money for rs3 motors and it is definitely not necessary. You can get 750hp out of the vw motor turbocharged with headwork and cam easily. Basically whatever the 2.5 tfsi will do but more because they don't cam swap usually. Cams are too expensive for dohc motors for a 40-50hp gain. It's double hp in the 07k with valves so well worth it. 300 something na is worth it. The cast cranks are good to 500. After that is ttrs crankshaft. Iroz has been snapping them though so I'm looking into billet. If I can get them for under 1500 in a multiple crankshaft buy maybe. Still working on that.

[@curvs4me]

@@BoostBrothersGarage If I do it i'll send you a head to put on your car. If it's putting out 500hp people will be more than curious lol.
