SCCA EMod MGB GT V12 Build

The Borg-Warner Super T-10 arrived today. I chose it because it is supposed to be strong, light weight, short(ish) and has external shift rods so moving the shifter around should be easier. There is 10" between trans and diff yoke. [URL=http://smg.photobucket.com/user/loosecannon/media/MGB-GT/IMG_3676_zps6qbakpye.jpg.html][/URL]

I also installed the front bellypan but think maybe I chose aluminum that is a touch too thin (16 gauge) because it is wavy. [URL=http://smg.photobucket.com/user/loosecannon/media/MGB-GT/IMG_3665_zpsrt138iat.jpg.html][/URL]

I am so stoked over how the shifter worked out. The first picture is the stock shifter position, obviously out of reach of the driver. The 2nd and 3rd pictures are the new position. What I did was move the shifter to the front of the transmission and flipped the shifter 180 degrees. Now the rods that were formerly pushing on the shifter arms are pulling on them. By itself, this would have flipped the shift pattern,too but all I did was change the rods and now it has a normal H shifting pattern with 1st through 4th in the right places. The only strange thing is that reverse is now top right instead of bottom left, but the red handle is a reverse lockout so no issues there. The trans shifts with positive and easy action, at least sitting still. Ignore the shift knob, it's incorrect.

cool … wish I had even 10% of your fabrication skills

Shifter win. Mega win.

Gonna be fun getting fuel into that tank and not filling up your floor pan.

I still have the remote filler from the hard top car but it adds weight. I think a funnel with a long hose will solve any fuel filling issues but if not, a can mount a cool race filler in the middle of the rear deck.

Thanks. I learned all this by doing...and making mistakes and doing it again. Nobody is born with the ability to form a sentence, you learn one word, then a couple of more and eventually you can string together a sentence. Go get a used MIG and learn a few words :)

I was thinking holly blue pump as a transfer pump between jug and cell. Way more complex than the other options.

Mounted the intercooler today. In case anybody wants to know, the core is 12" x 18" x 3.5". I started with bolt-on lower supports made of thin wall rectangular tube. [URL=http://smg.photobucket.com/user/loosecannon/media/MGB-GT/IMG_3686_zps9mvwl9vu.jpg.html][/URL]

Then sliced off the old top engine mount (good thing it was only tack welded) and made a new one that incorporates the top intercooler mount [URL=http://smg.photobucket.com/user/loosecannon/media/MGB-GT/IMG_3690_zpsnvjgex53.jpg.html][/URL]

Right where the intercooler outlet is, was the mounting location for the power steering pump. I sliced that off in the band saw and now it's a straight shot from intercooler to throttle body. [URL=http://smg.photobucket.com/user/loosecannon/media/MGB-GT/IMG_3689_zpsvxz4zxme.jpg.html][/URL]

age, lack of tools ($$$), lack of a place to do the work …. etc

I now have the world's shortest windshield, at least it doesn't impair my sight lines to the cones [URL=http://smg.photobucket.com/user/loosecannon/media/MGB-GT/IMG_3699_zps2dob9ydo.jpg.html][/URL]

An early 80's VW Rabbit steering wheel . . .

On a MGB?

No, actually it's a Grant steering wheel. I purchased a whole box of these wheels to use on the karts but they were too big so I sold off all but a couple of them.

Slightly similar, but much nicer ! Great choice over the usual old three spokes with the little round holes in them style.

The transmission mount was a huge P in the A. I wanted it removable and I also wanted to use the original bracket but both these things landed up making for a lot of extra work. I bought some thick wall tube that I could thread, then I welded the threaded tube into the frame where the bracket is going to bolt to. Getting them situated perfectly was sooooo much trouble but anyways, here's a pic of the final product.

Inspired by how my old 911 was jacked up, I welded in a tube on either side of the car at the approximate balance point and can jack up the car to swap tires [URL=http://smg.photobucket.com/user/loosecannon/media/MGB-GT/IMG_3714_zpskhjrgrcq.jpg.html][/URL]

The whole car as it sits is up to 1425 lbs (w/o driver) so by the time the coolant and aero bits are bolted on, we will be at minimum weight

The driveshaft arrived today. [URL=http://smg.photobucket.com/user/loosecannon/media/MGB-GT/IMG_3716_zps1yxxvuxn.jpg.html][/URL]

Your shaft is tiny, but at least it's thick.

I like how the gearbox extension housing is longer than the driveshaft.

I wasn't happy with the trans mount so in order to make it lighter, I needed to make the right side engine mount stronger. Here's the way it was originally: [URL=http://smg.photobucket.com/user/loosecannon/media/MGB-GT/IMG_3731_zpshgbkjruc.jpg.html][/URL]

And how it is now (still not fully welded) [URL=http://smg.photobucket.com/user/loosecannon/media/MGB-GT/IMG_3732_zpsn12dqwyo.jpg.html][/URL]

Stripped of the bodywork, it looks kinda like an Ariel Atom [URL=http://smg.photobucket.com/user/loosecannon/media/MGB-GT/IMG_3733_zpsgfznzngd.jpg.html][/URL]

4 hours...that's how long it took me to build this new transmission mount. I never liked the old one and since I will likely be racing this car for many years to come, I may as well take the time to build one I like. It's made entirely of sheet metal and flat bar and I wish I had the money to get someone to laser cut the holes but all I have is a plasma cutter and a die grinder to do them myself. Also, the old mount weighed 8 lbs and the new one is only 4 lbs-and that makes me happy. Here it is tack welded [URL=http://smg.photobucket.com/user/loosecannon/media/MGB-GT/IMG_3740_zpsfnquxecu.jpg.html][/URL]

and installed

This build makes me happy and jealous. Happy to see fab work jealous I cant build something like it xD

I built a driveshaft safety hoop and fortunately, it will keep the front and the rear of the shaft from doing damage in the event of failure [URL=http://smg.photobucket.com/user/loosecannon/media/MGB-GT/IMG_3752_zpsmnyqebfk.jpg.html][/URL]

I also moved the power steering motor over so I could lower the intercooler and improve my center of gravity [URL=http://smg.photobucket.com/user/loosecannon/media/MGB-GT/IMG_3753_zpsad8fjxw0.jpg.html][/URL]

In reply to loosecannon:

Driveshaft safety loop is almost as big as the driveshaft. Question, what kind of welder are you using for all this. I'm looking into buying a welder and starting learn to weld. Always interested in what others are using?
