MGB build for speed events - Australia - V8 conversion and lots more

Dry sump pump. It had to be rotated on its mount to allow the returns to clear the sump. Sump will likely need to modified as well down the track to put in more pickups.




Front brake mock up.


Dry sump tank mounted. Can be accessed via small panel in the section behind the seats.

Fuel tank mounted. It's about 81.5litres but due to the angle of our modified boot floor we will need to have the car jacked up to fill it that much. Should be good for 30 minutes of racing.


Lifter pump mount. 2nd photo is a reinforcement to stop it wobbling too much.

Fuel system is complete. As it's mainly push on fittings I've left one end off for now as it will all need to be removed for painting etc.

Some months back I painted the rear section of the cage and took the diff out to clean up the rust inside and out. I also fitted a drain plug to make oil changes easier.

It's a full floating 9" with Strange lightweight centre, Detroit locker. The only negative is we have no negative camber which is not optimal, but it's too expensive to fix at this stage, given the focus to get the car on the track and optimise later. I will however talk to the fabricator and see if it's worth doing the trick where you use a welder to bend the housing a degree or so. This apparently is easier with floating hubs. My concern is getting it even side to side.

Next up was to remove the surface rust and paint the floor underneath the car. I finished that and then sat my son in the car to test locations of switches on the dash (next post), only to find he'd grown 5cm or so in the last 2 years. This meant I had to cut out the existing seat rails an put in a completely flat floor with compliant mounting points. I'm about 10cm shorter than my son so we needed a forward and backward position, plus we did an angled back position as well. Very time consuming getting the mounting plates and captive nuts positioned perfectly.



I got to assist in the pits for the one of the Australian V8 MGB racers, who kindly made a set of even wider rear flares for me. We should be able to fit a 13" rim in easily now.

Next up was wiring. The car had a MOTEC loom that was only setup for dyno only. I had to do the loom from scratch. 200 wires for everything from taillights to shock travel sensors.

I still ended up needing some relays for EPS, Hazard lights, fuel pumps and starter solenoid.

Took me about 3 months from empty spreadsheet to completed wiring.

I'll be using a Haltech Nexus R3 and UC10 dash which gives me enough I/O between the two with a few inputs left over.
