What Gearbox are you using. Midget 1500


Senior Member
Hi Guys,
I am building myself a track Midget 1500 but appear to have hit a bit of a wall when it comes to the gearbox.
Engine wise, for anything performance i have had to ring companies in the US as the UK do not seem that keen on the Triumph engine. We build a lot of performance A-Series engines at work but fancied a change, and cannot wait to get the Midget out.

My question, have any of you built a performance 1500, if so, what gearboxes, or gear sets did you use?
If it was a road build i would go the Ford 5-Speed route as we have with the A-Series, but with this being a track car i am keen to keep it a 4 speed.

Just curious to see what is available and if you have any experiences yourselves?

Many thanks,

Can't help with the transmission, but, would love it if you could share the specs of that engine - looks amazing!


What are you doing to make sure the middle rod's and main get enough oil? Dropping thrust washers?

Glad you like the look of the engine, we can't wait to get it built and in the car, the car itself has had a lot of upgrade work and will be used as a promotional vehicle at the race meets, hopefully with it being something different it will capture peoples attention. I will put up some more pictures and full spec for you shortly.

In many ways the 1500 is similar to the highly modified, bored out 1300 A-Series engines. So many of the same procedures. Centre main strap, oil cooler, correctly balanced and get the oil circulating through the parts that need it the most.
I will upload pictures of the work to combat the issues, for anyone that is interested. And then let you all know how it goes down the line :smile:
