Hello folks!

I'm new to spoolstreet. Actually, this is my first post in here.

I thought it's a good time to share my build. We have here probably the first N55 full build motor. The project still in the works. All the work has been done by ABR Houston. They have done an amazing job so far. The build motor includes closed deck, ported and polished heads with Ferrea valvetrain.

Here is pic of the small block:

Here is the cylinder heads:

Also, I'll be installing Big Boost 3.4 Turbo kit.

The car still Auto for now. I still debating in between upgrading to a full build Propulsive Dynamics AT or DCT swap.

More pictures to come stay tuned

Awesome project. My vote is DCT swap but maybe I'm biased lol.

While we wait for the crank hub. I decide to work on the transmission.

I was debating in between getting my AT build or DCT swap. Like most of you know, the DCT swap is pretty expensive. For that reason I choose to build my current AT.

BTW, Propulsive Dynamics is not doing the AT builds anymore. They’re just selling the upgraded clutches and bushings.

Anyhow, I talked to [email protected] about it and he didn’t hesitate to do the work. So far, I got PD clutches and bushings.

Also, all trans internal parts (input shaft, basket, etc) has gone thru deep cryogenic process to increase strength and durability. Thanks @nitemare for the tips.

Today, I received the torque converter back from TCR. They increased the stall to 2800-3000.

Funny story on the PD discs.... you must have been one of the 2 people who bought last Thursday or Friday. I bought the last set of discs from Jason friday night and as far as I am aware he has no plans to make more. So consider yourself lucky haha

So, is anyone making clutch upgrades for the 6HP, then? If not, you should get thickness measurements on all of the steels, at least. One of us could KickStarter a batch later, if needed.

Hey, ap845, what are you planning on doing for fittings to the trans and what cooler? I bought some of these fittings off of eBay, a Derale 25792 thermostat and a B&M 70274 cooler that I'm going to put on for my X3's 8HP. Those 3,000 RPM AWD launches and 1/4 mile runs aren't particularly nice to the fluid in terms of temp.

PD was the only one I know that was doing the upgrade.

I'm planning to tap into the OEM trans cooler lines using the Vader Solution trans fittings. For the cooler, it will be a Setrab 25-row and FSM-165 thermostat. I'll add pics of the whole kit later.
