12a Triumph Spitfire
 
Finally have a few good pics of my 12a powered Triumph Spitfire to share. I am getting a custom stainless steel header made for the car soon, and am looking at a lightened flywheel from RB. The motor is a 1985 big streetport with 465 Holley, 310 Flex-a-Lite fan, new short rad, 2nd gen coil for use with direct fire. I am using stock tranny with the mazda slave connected to the triumph clutch master. Enjoy!

Nice! How does it drive?

My 13B MG Midget will run soon.

Drives way better than I thought it would. Direct fire eliminated all the backfires from the exhaust leak I have. Starts great, pulls hard with a nice kick around 5100. Has some stumbling at very low sudden throttle inputs. I can't make any final evaluations till it has a proper header though, as the current version is choking the engine at high rpm. Handles like a dream as the weight is all so down low.
I drove it 500 miles last weekend to and from knoxville, and it pulled 24 mpg going 85 mph. Drove nice and cool and smooth the whole way. Gets better mpg then the rx-8, but it does weigh half as much. It can only get better.

Sounds like a lot of fun!

I wold like to know how that 2nd gen leading coil is wired in

It looks like 2GDFIS to me. There could also be a hidden MSD somewhere on the car.

stunning and amazing!
It's cool to see pics of those kind of cars. Talking about engine swaps is good fun, but it makes so much more sense if you can also see something.
Nice job, how long did it take?

You gonna do a nice post with lots of details? I plan on attempting a midget of my own sometime and would love to see what you have done.

The 2nd gen coil is run off the leading ignitor on the dizzy. I removed the 2nd gen ignitor and wired in the coil with the ballast resistor. The 2nd gen coil has a wire clip with 2 wires going in, power and tach? I think, so I just used those two wires for power and ignitor signal. Very clean, not a hack job by any means, and all connections were soldered together.
The project took about 2 months to go from running driving 4-cyl to running driving rotary. I actually finished it all in 6 weeks, but had to wait 2 weeks for my RB carb to be converted to streetport and shipped back to me. It was a rough 2 weeks waiting for it to be able to drive, but its great now.
I appreciate all the nice comments!
Jeff, what year is your midget? What motor did you originally have in the car, and finally, are you running fuel injection or carb?
