My uncle has got a 63 Mini cooper(1284lbs). I've been strongly pondering puting in a 13b twin turbo into the car. But I am not sure the reality of it. After adding the motor and a couple more standard features it will prolly weight close to 1500lbs. I'm wondering if it would be worth it. The 0-60 of a 145hp mini from this era was 3.5. The difficulty of an entire drivetrain switch would also be rather interesting. Looking for ne n all input on the idea.

I could be wrong...but i don't think 0-60 was 3.5 in that era. most supercars nowadays come close to that but don't beat it. also..it would probably weigh a lil more than 1500lbs

i also thought those old minis were around 100hp...but i'm not really sure

Ok let the guru step in here.



850cc motor had 34bhp at 5500rpm 44lbf. ft at 2900 rpm

998cc motor had 39bhp at 5250rpm 52lbf. ft at 2700 rpm

1098 motor had 45bhp at 5250rpm 56lbf. ft at 2700rpm

1275 motor (carb) had 76 bhp at 5800rpm 62 lbf.ft at 4500rpm

1275 MPI (only late models) motor had 63bhp at 5500rpm 70lbf.ft at 3000rpm





1275 is as big as they come in stock form. They do bore them out to 1410 and make about 125hp. A 13B is way to big to be stuffing under the hood anyways. A single rotor would be more like it.

thanks for backing up my guesses https://www.nopistons.com/forums/pub...IR#>/smile.png

Oh, its true they do weigh under 1500lbs. They are almost literally a go-kart with a roof.

hmmm they sell single rotor engines at rotaryaviation

Yeah I know. I had seriously looked into doing something like that. With time and more money I just might.

how much power do single rotors make?

Probably not a whole lot. But with a small turbo I don't see why 125hp or 150hp wouldn't be possible and still reliable.

I've seen a mini with a 12A street port, but it was converted to RWD

First time I saw it I thought "what the F**k" then I saw the engine bay.

yeah i think it would have to be rwd, the rotary is too wide to keep it fwd

I wonder how he fitted the tranny and driveshaft down the center of the car. I'm guessing he had to modify some of the interior, firewall and flooring to make it fit. Sounds cool though, too bad you don't have any pics.

...sorry I should have made myself clear, I meant the car will not weight 1500lbs with the rew in it

I gotcha. Will be pretty close though. At an average of 1300lbs you would have an extra 200lbs before you went over 1500lbs.
