2011 R55 Non-turbo Engine upgrades?

Iíve just recently purchased a Mini. My first ever mini. All I know is that itís a 1.6L DOHC(apparently) 4-cylinder Naturally-aspirated engine pushing somewhere around 120Bhp. Now I want to get a tad more power, like an extra 100horses. I want to go all motor. Thinking of dropping some cams and getting a tune. But I havenít found anything and I donít know if thereís a JCW package I could add on or purchase. From what Iíve been told itís be best to trade for an S/JCW or just swap the engine..

I want to just build an all motor but I can’t find anything. Is it possible to swap heads? Pistons cams? Any help I can get to find the right parts, and get my car tuned properly

There is no aftermarket parts for that motor, mainly because there is no demand.

You may be able to get an intake and an exhaust

I found a cold air intake, and I have already done a muffler Delete. Only exhaust-kit I found was a universal magnaflow catback kit. Thanks, but is it possible to get cams custom made?

Welcome to NAM.


Going to move you to the Gen2 Mod section, might get some better views there.

Fellow Gen2 Justa owner here - I think your best option to get higher horsepower is to trade cars for a S model.

Have you tried using the sport mode?

Buy a Magnaflow exhaust manifold cat assembly. Unbelievable increase in power. Go under the Gen 2 Non-S modification forum and you will see my posts on this along with pictures. Hands down, the best thing you can do. Look at the pictures of the original assembly and then look at the pics of the Magnaflow unit. Incredible change in my car!

Conventional wisdom is that the base, NA engine doesn't have much more to give. A few weeks ago someone here discovered that's totally not true:

But if you are looking to add 100hp, you have the wrong engine, even with the Magnaflow exhaust header & cat. You'll be wanting a turbo charger.

Get a Honda

if you are looking for 125hp/liter from a naturally aspirated four cylinder then look a Honda S2000 or Acura Integra Type R. Incredible machines. I have an S2k. Given that thereís a turbo Cooper S which has decent tuning potential, an aftermarket for the Mini never really develeped. Even if one had I doubt weíd be looking at much improvement without big bucks.

Iím going to need to see dyno numbers. I trust the forum member with the Magnaflow header but Iíd bet the improvement is less than 15 hp which would be good.

i agree, a larger bore manifold is going to lose exhaust gas velocity & torque-thatís why it gives the illusion of increased power as it revs itself out of the reduced torque pit thatís been created.
I want to see credible dyno graphs before/after to back up any claims, the quality control sounds dire as well
