JHM Supercharged 4.2L C5-allroad with JHM 0A3 6-Speed Swap

**Jake@JHM** · 05-09-2016 11:01 AM

Hey guys!

Some of you already knew about this, but here is a cool build that we completed for a customer!

There will be more information and parts available here shortly for the C5-allroad 4.2L!

Stay tuned for another video walking through this car with all of the upgrades we installed.

very nice

Is this kit going to be available for the belt driven 4.2 or only for newer chain 4.2?

**a4kamila6** · 05-09-2016 11:57 AM

I was expecting a screw type blower but am happy its a vortec.

Cool project. Sounds great. Looks a bit slow though compared to an ots stage 3 2.7 car.

Please tell me the owner is going to Camp Allroad this year.

As of right now it is not in the works.

That wasn't WOT, the media guy was just filming going to redline for the "shift scene". I will note that for a big heavy allroad this thing scoots.

No idea! He is Happy2b5 on this forum.

Good to hear. Would love to see some "performance video" of this thing.

I think last he said about it was it was up in the air. I really want to meet him too. And really hope he moves to Chicago. If ChicagosPhantom can fix his allroad ( :p ) and Jeff moves here then that's a pretty fun trio of allroads.

**SteelyS6** · 05-09-2016 05:07 PM

I really hope he comes to camp allroad! Would love to see more details on the build, including the transmission swap.
Makes me want a 4.2 allroad now, sheesh!

**4rings2turbos** · 05-09-2016 06:26 PM

Geoff! You HAVE to stop! Haha

We have a video in the works right now that goes over the build and talks about it!

**SteelyS6** · 05-09-2016 07:37 PM

If money was no object I would probably own eight or so C5's! ;)

**happy2B5** · 05-09-2016 08:15 PM

We are 99.9% planning on coming to camp. Want to meet everyone, too and see all the badassness that is the allroad (and newroad)

**Jake@JHM** · 06-21-2016 04:11 PM

Here is a behind the scenes look at this 0A3 Swap!

**JTown77** · 06-21-2016 04:42 PM

Could you run the B6/B7 auto on the 4.2 allroad? Are there headers for the chain driven 4.2 auto?

**happy2B5** · 06-21-2016 04:53 PM

Oops, misprint

**happy2B5** · 06-21-2016 04:53 PM

Was an option considered but once my zf from the c5 gave way, I wanted to row through the gears in a 6mt

I am sure you could, we just haven't tried it yet.

We have headers for Automatic B6-B7 S4 S4s which could be modified to fit.

Unfortunatley like many 4.2 allroad performance parts, "Product not found!"

I would definitely be interested in adding a gear and headers along with a tune!

Haha The headers are for the "s4" so clear your selected vehicle

**catriple** · 07-09-2016 07:20 AM

Can you tell us more about what it takes to get the 0A3 to fit? I'd love to ditch the clunky clanky notchy 01E in my c5 allroad in favor of a 0A3.

Details!
