Welcome to GTT's proven range of performance packages.
Introduction to the GT Tuning Mini Fitted Performance Packages
Not only will you find spec that is higher than our competitors (eg Iridium S'Plugs, Idler Pulley & New Drive Belt included at all levels), but prices that are unchanged since 2005. Each package is based on achieving a combination of maximum power, drivability & reliability, with maximum value for money.
If your car already has non GTT performance parts fitted that you wish to add to, we can produce a custom package for you, so no need to feel left out! The testing and developing of the GTT conversions includes many thousands of road miles, hundreds of track miles, drag racing & rolling road sessions.
If we (Steve) cannot break it, nor will you! We have stripped the engines, gearbox's & most other parts of these cars down to the last nut & bolt. Only then, in our opinion, should license be given to sell & fit tuning parts to these cars. Of course we did have a head start, which is 25 years in motorsport, competing, designing & manufacturing parts, and 25 years involvement with aerospace, Formula 1 and Indy Car parts manufacture.
Free GTT Service / Safety Checks Included With All GTT220 - GTT260 Conversions
When completing any GTT220 (or higher) conversion our passion for perfection , maximum reliability & ultimate safety means that we now include at no extra cost all the following checks & ‘top ups’.
Check tyre condition +report
Check tyre pressures, adjust as required
Check all wheel bolts for tightness (often very loose!!)
Check oil level (often very low !!)
Check coolant level + free top up if required
Check + free top up of windscreen & headlight washer fluid reservoirs
Check power steering fluid level + free top up if required
Check brake fluid level + free top up if required
Visual check of brake disc & pad condition
Full diagnostic fault code readout & re-set
Engine bay cleaned & valeted (by hand -no steam cleaner!) ‘Tender love & respect’
Full road test & report
Notes: Power figures are typical. Please note we have used only fully independant rolling roads to establish output power during development of these conversions. Actual power output is very dependant on temperature, humidity,and engine/supercharger condition. Unfortunately it is also a sad fact in the motor trade, there are those that occasionally will fudge results on there own dyno to make their conversions read high & likewise, competitors conversions read low. For these reasons we only use fully independant 'non Mini specialist' rolling road houses. Some items within these conversions are 'exchange' eg cylinder head & throttle body. Technical info & pictures of the components of each package can be found in the 'Performance Parts' section.
Cooper & Mini One Conversions
GTT 130-137bhp ecu-rap upgrade £299+vat FITTED
PERFORMACE PACKAGE UPGRADES FOR JCW 210 CARS.
Due to the increasing demand from customers with JCW210 kitted cars feeling the need for more power & torque,we are now including a number of GTT fitted upgrade packages just for you! Each package is carefully compiled to give ultimate increase in usable performance & improved reliability within each price constraint. We have also tried to make each conversion as discrete as possible !!!. Where less discrete items (such as the all important GTT intercooler )are included these can easily be substituted back to standard in just a few minutes. We have included approximate power gains that can be expected with each package. (eg +20bhp.) We have done it this way as although rated at 210bhp,a typical JCW rolling road output we have found to be circa 195-198bhp. A JCW210 producing 195bhp will increase in the above example to around.215bhp. Please also remember the torque increase achieved with GTT conversions.The increase here in the all important mid range is what you will feel,use & enjoy everyday!
