Making some serious progress with this Digital PDM Electrical System for the BSM AWD DC2 Integra Type R. Since the vehicle will use a full digital PDM Electrical System we designed an Open Source template and design with an Android APP to use the system from a Tablet or imbedded Computer. In this case Lattapanda Alpha Micro PC Systems allowing us to decode, modify and communicate directly with our Fueltech through CAN to the rest of the integrated systems we are integrating into the chassis.

BIG SPLINE. BIG POWER. PROVEN RESULTS.
At BSM, we do not build parts on hope, hype, or luck.
Nothing by Chance.

Blacksite Motorsports is getting closer to the official release of our BIG Spline Torsen CR-V Rear L*Ds — and yes, they are here, tested, and proving exactly why we built them.

We have tested these units many times with great success, and they continue to show what the AWD Honda platform has needed for a long time: stronger engagement, better consistency, and a far more serious rear differential solution for builds that are done asking factory parts to do motorsports work.

These units have been tested to 1600 HP with no failures and have also seen 7.47s in the 1/4-mile with Wanted Performance on their 1600 HP K-powered EG.

So no, this is not just another “upgrade” for people hoping stock parts survive real power. This is a proven solution for builders who expect the rear driveline to actually do its job.

Our BSM BIG Spline Torsen CR-V Rear L*D is designed around the Wagon 25-spline axle fl**ge configuration, giving the CR-V rear differential a more capable spline arrangement for delivering more consistent power transfer than the standard CR-V setup.

BSM BIG Spline Torsen CR-V Rear L*D

Pre-launch units available by select inquiry

Expected pricing: $1050 + shipping

Limited quantities available for consideration before full release

Tested to 1600 HP with no failures

Seen 7.47s in the 1/4-mile

Designed for Wagon 25-spline axle fl**ges

Delivers more consistent power transfer than the standard CR-V setup

We are not announcing these as a full open public release just yet. However, we are willing to consider a select number of pre-launch sales for serious builders who understand what this part is, what it does, and where it belongs in a proper AWD Honda build.

For the AWD Honda crowd pushing real power, this is one of those parts that separates the people who say they are building AWD from the cars that actually hook, transfer, and survive.

Because at some point, the rear differential needs to stop being a passenger and start becoming part of the solution.
DM BSM to inquire about pre-launch availability.

Billet AWD Parts Don’t Assemble Themselves… Unfortunately.

Another 3 Billet RT4WD Viscous Couplers are being staged for assembly at Blacksite Motorsports.

Seen here waiting on their remaining parts and components are the billet carrier bearings, which arrived yesterday courtesy of UPS. Today, the coupler bodies arrive with the shafts, input fl**ges, output fl**ges, and carrier bearing access doors.

And because apparently we like staying busy, this batch will be followed by 10 more RTAWD Viscous Couplers for CR-V differential assemblies.

Things are starting to pick up.

A few weeks ago, we also received the first of 10 new Torsen Big Spline CR-V L*Ds — the same L*D platform used in the 1600HP AWD Civic running 7.47s in the quarter-mile.

So yes… while some people are still debating whether Honda AWD works, we’re over here building the parts that prove it does.

Nothing By Chance.

Blacksite Motorsports Tip of the Day

Today we started our first electrical project on a 1991 Honda Civic DX, and it is a perfect reminder that cheaper is not always better.

This EF chassis originally came with a D15B2 dual-point engine, but the customer’s previous wiring attempt created major issues when the ECU connectors were cut from the chassis harness. On these cars, the chassis harness and ECU connector wiring are tied directly into the engine management system, so cutting corners can create serious electrical problems.

To correct it properly, we will be working with our partner Wireworx to install the correct dual-point to multi-point fuel injection adapter sub-harness, along with a Wireworx tuck harness and firewall grommet pass-through for the H-series setup.

This Civic will also be our first EF chassis build and is being scanned and evaluated for our V2 Elite Class all-wheel-drive system. The car will feature Hasport H-series mounts and is being built toward a daily-driven H-class AWD setup capable of supporting 500-plus wheel horsepower.

The lesson is simple: wiring is not the place to guess. Proper planning, proper parts, and proper ex*****on matter.

At Blacksite Motorsports, we do not just make it work. We make it right.

More work went down in the shop this weekend, and the progress continues.

The EG Civic is still on the rack and has now received its front suspension assembly. We are currently pressing bearings, hubs, and snap rings into the CR-V front knuckles so they can be installed on the car. While we wait for the billet front knuckles to arrive, these front suspension components will allow the car to roll around the shop and free up space on the lift.

That space is needed so we can bring the EF Civic in for scanning and modeling as we continue building and developing new solutions.

This EG is being prepared for a five-lug conversion using Acura TL front calipers and rotors. It has also received Energy Suspension bushings for the lower control arms, Skunk2 upper control arms, and Brian Crower front coilovers. While I personally prefer Pro Car Innovations suspension components, the customer selected this setup for now. Moving forward, I will continue encouraging him to move away from Skunk2 and consider stronger options like HardRace or PCI for better overall performance and reliability.

We are also continuing to shave the engine bay and remove unnecessary emissions control components. This will clean up the bay, simplify the layout, and help prepare the car for its new wiring harness, B-Series heart, all-wheel-drive transmission, and Hasport engine mount setup.

This weekend was all about progress, preparation, and keeping projects moving through the shop. Every step matters, from suspension assembly to chassis preparation, bay cleanup, wiring preparation, and future AWD developments.



More updates and progressive designs are coming from the shop soon.

Stay up to date with our progress by following along.

This isn’t just another part being machined — this is AWD support being built from billet.

The BSM Billet Viscous Coupler is taking shape, designed to support both the Internal RTAWD and External RT4WD Coupler layouts.

Precision machining, purpose-built fitment, and a design focused on keeping these Honda AWD/4WD drivetrains moving forward.

Nothing By Chance.

Follow along as we move through machining, fitment, and the next stage of development.
