Mini Mania's Classic Mini Engine and Transmission - 1275cc
We use a Mini Mania 1275cc Power Unit that is a Mini Classic engine repair assembly that is guaranteed for a period of 12 months or 12,000 miles. Using our extensive experience, we rebuilt both the Classic Mini engine and transmission to ensure the best possible balance of economy and performance; you get superb performance at a reasonable cost!
The transmission is the rod change linkage type that uses inboard CV joints & 3.44:1 final drive ratio. (Special order units with the older remote shift and yoke outputs are also available!) Clutch, flywheel, and all covers are in place!

Standard Minis have always been slower than their handling was capable of. Fortunately, many people have devoted their careers to making Minis go faster. As a result, you can fit your Mini with a double overhead cam 16 valve cylinder head, a turbocharger, and programmable electronic fuel injection.
Hello from Australia here just asking of what race motors can you build as I have a mini sports sedan and want to stay with a mini motor but want to put out around 150-170hp at flywheel and do NOT want turbo or supercharger. I hope to here from you guys soon
Regards
Answer:
Thanks for asking. While your goal is pretty optimistic we can get pretty close but to me honest it would not be a great street driver. But perhaps I should first ask about target of 150hp. What is the HP of your current motor? How was it tested? How did you pick that target? Take a look at this info: https://www.minimania.com/Is_Your_Dyno_Lying_
Remember that a stock Cooper S of 1967 produced 72HP!

What are the price ranges based on shipping my own 1275cc engine and gearbox? You list 3 options in your engine rebuild program, just want to get a sense of cost before crating it over there. Also I would like to retain my original engine number tags etc. on the block, is this possible?
