Engine mount brackets are done. Due to height constraints, I'm only able to run 1 hockey puck on either side this time, but it's all good. Fits like a glove with the HPFP's which I thought would be an issue. Also, the OEM C6 S6 fan's and fan shroud with the 2" radiator I had with some trimming so I'm super excited about that. I'll be using the OEM fan controller and harness so no more flipping fan switches on and off!

Headers are next!

Looks deceptively like it's in its natural habitat.

Any plans for heat shields on the intakes (likely after header fab)?

Its scary how at home this engine sits in the C4 chassis.

The intake plumbing was just to make it look complete...
I'll be doing 2.25" piping on either side to run under the headlights and as far away from the headers as possible.

I'm slightly reviving this simply because I can't get the car to stay running and need some serious help!

Engine/transmission is all hooked up and ready to go. Both ECU's had the immobilizers deleted and I'm not getting any weird fault codes.
The car will crank and momentarily start and before I can even turn the key to the off position it turns off. Like it runs for a split second before it says NOPE!
Any idea's on what I could look for?

-Throttle bodies are moving with the gas pedal
-Ignition, fuel, and ecu relays bypassed to no avail
-Ahhhhhhhhhhh



I've been using my neighbors generic code reader so maybe there's something that isn't quite popping up. OBD11 Pro from ECU Tuning gets in Tuesday, for now I'll finish up the radiator until then.

Any codes for the crank position sensor? Is it grabbing signal from the flywheel/transmission properly. I've never looked at a 5.2, is the sensor in the usual spot on the trans? Or in the block?

The RS4 flywheel accommodates for the changing in the crank position sensor. The issue was that you need to have the C6 S6 instrument cluster connected, as the ECU signals communicate through it via CANBUS.

Cars running great now

Sounds great, can't wait for the first video of it on the road.

I'm about 3000 miles in on the 5.2 v10 so far and everything it holding up great. We've all but finalized the tune and oh my 'lanta, it's glorious (I attached a short video for ya). Engine bay is 100% buttoned up, I mean... it's pretty damn great! Also bought 2 more 5.2's, one as a spare and another for a possible future (turbo) project.

Has Hank seen this? Seems like this should be his next swap project, kinda goes with his R8 shop projects.

But Joel, this is pretty freaking cool.

Thanks everybody!

Here is a real short clip of the driver. Keep in mind there's still a 4,000rpm soft limiter so in reality, this car's not even close to singing! As my buddy said... "Hey is that a supercar coming?!?!.. Oh wait, just a shitbox". Haha

Now this is awesome! I purchased an AEM CD5 cluster with GPS and it plugs right into the OBD2 port! It has a super high baud rate so responsiveness great! Still playing around with it, but absolutely loving it!

My parents are in town and my dad insisted we go get some external shots of the car. Quick compilation of just some of the fun we had today.

For some reason I can’t see pics or video . Maybe it’s just the viewing on my phone

Not even sure what to say, other than I hope you keep the S6++ (because it's more than an S6+) in your garage as long as you can. The 5.2L is a pretty special engine. One of the last great engines.

Some more rips for you guys as well as just a general update on everything! I plan on keeping it for a while; only consideration to sell it would be to have something I'd feel comfortable driving my daughter around in (It's getting there though!)

I think for me... setting up the vacuum brake boost, power steering, is all thats needed.

The air conditioning will never happen unfortunately, which I'd want, but at the same time as long as the first two are finished, I'd be happy.

Which leads me to my next question, who rebuilds power steering racks?

They probably have one in stock. They need a core.

Get it, man!! That thing sounds wicked!

I had always wanted to do a swap like this, and I'm glad I can live vicariously through you after I sold my V10's along with my hopes and dreams. How'd you come across the idea to use the B7 RS4 timing cover?
