944 - VW Swap
43 Attachment(s)
Greetings Gents
I wanted to share my project with the group here. Some of you may have seen it over on the bird but for those who haven’t, here it is. I’m working on an early 944 that my brother gifted to me after abandoning as his own project. It has been apart for a decade… was either this or scrap. The long story short is he bought it from the wrecker in Connecticut who stated it needed a head gasket. When it showed up, it was obvious the engine was toast with cracks in jugs, smashed pistons and foreign object damage to the head. He picked up a parts car and engine and then quit so it sat for ~9yrs. I’m not a fan of the stock 944 engines so that wasn’t an option. We tooled around with the LS swap idea but ultimately decided to go with something we’re more familiar with and in the blood lines of the 944. We’re going to adapt a VW/Audi engine. More specifically, the AEB 20v from B5 Passat/Audi A4 lineage is what we’re using. I truly wanted to drop one in with limited fiddling but I couldn’t help myself when I found a lip on the jugs… so we built it out. Enough words, here’s the pictures through present day: Commence picture waterfall timeline... starting in October 2013.

Little loose is okay but this was out pretty far.

Intake manifold needs to be trimmed to a taper plenum to clear brake booster. Waterneck on the back of the head will need a solution... either a super tight elbow or cap and relocate. Decided at this point to switch to a different bell housing moving the starter to the engine side of the clutch. Have a ME friend who is going to help with scanning/forging our own design. We’re getting ready to start working again as the car sat all summer; the best time to build is during the winter when cabin fever sets in. Thanks for reading – more to come over the winter. |

Holy Poop.... :eek::eek::eek::eek:
Good work man! Can't wait to see where she ends up! :thumbup: Cheers! Ethan |

nice work.
i debated you about doing this but the more i thought about it, the more i liked it. that head is a cool design...and that engine is tiny! you could fit two more dogs under the hood. |
Kudos for going outside the box. Very nice build/project! I always wanted to see a vr6 944 - I may end up doing one with my brother who is a VW guy.
And yeah, that engine is tiny! You could call it a mid-front engined car now, as most of the engine is behind the front axle. |

how much more displacement can one get from that engine?
|
You can put a TDI block/crank under the head to go up to 159mm rod. That bumps you to 2.2L with some custom work. Not sure on the largest displacement out there but on turbo application the rate of return is diminishing.
|
Let me know how the bellhousing stuff goes, I still need to figure out which direction I'm going to go for my 07K swap.
|
Will do - if we can get a solid design then we'll pump them out domestically to help other people.
