The factory turbo is being held back by the ECU tuning, it is capable of producing more boost than the engine internals can handle if left uncontrolled. If you just slap a bigger turbo on, the ECU with just open up the wastegate to limit the boost again so the only thing you will "Gain" is more turbo lag.
Trust me on this as I currently have a bigger turbo on mine and ended up with less horsepower overall not more. It's cheaper and much more productive to get a good ECU tune using the existing unit.

What about a bigger turbo + a good ecu tune..what turbo do u have?

The tune in itself can provide as much boost as the engine internals can handle, so swapping out your turbo, unless it's already blown anyway, is pointless.

but like I said, the car ended up with less horsepower than it had with the JCW Turbo.
A bigger turbo will always give you a higher flow and will maintain boost and flow at higher rpm..ur car loosing power means that the turbo you bought isnt good or the tune is bad
Thanks Steven. Now I just need new clutch (OS Giken) to finish up. Suspension haven't been done just because of the bad asphalt we have here... Still contemplating on slapping some coils when this becomes my weekend ride but for now is my DD. The best mode by far was the Evolve custom tune, it really opened up the car.

I've heard nothing but great reviews on the Evolve tune. How many km/mi. do you have on your tune? Do you retain the sport button function?
I'm on the Koni Yellows and they are a great upgrade. My Roadster is my DD as well. You might even consider getting the coilovers from the new GP2...the factory has most likely tuned those to perfection.

I have about 7000km on new tune. Sport function is same as stock. Where can I get the factory GP2 coil overs? They should be pricey, no?

Send an email to Way, at Waymotorworks.com He recently took delivery of a GP2 and mentioned he might be able to source parts. It's anyones guess if and when Mini may make them available. I would be interested in them because I know the Mini engineers spent a lot of hours at Nurburgring as well as on the road tuning them...and yes, they will be pricey
