GP's injector size

can anyone tell me what Size the injectors are on a Mini GP?

ive read the engine is basically the same as the JCW, except for the IC and "upgraded" SC and computer tune.

Thanks!!!

I believe you are correct it is just the JCW with a bigger intercooler and tune. Dont think there is a difference with the supercharger though.

Injector size is 380cc, supercharger is the same as JCW, Intercooler has two additional rows, tune is different.

FWIW, the GP header/cat is a different p/n but I don't know the difference/s.

I am not sure if you are correct, I would be interested for someone to clarify this.

If you go on the MINI GP UK club site, they complain that so many Brit MINI owners have been ordering GP trim to make "clones", they're running out of stock. I can see their point.

You will get a much better result if you get a tune from RMW or Mynes than from the GP tune if you find it in your budget. RMW does some tunes over the country and if you can locate him near you that would be the best option. I believe they both do remote tunes also.

I agree with The Itch. To tune to GP specs would be a waste of time and money considering what you've already done to the car. You might want to consider a good header like an RMW before you tune, tho. Don't know what part of the country you're in but Way down in Hot-Lanta does a great tune, too.
