| Alta "Twurbo" Twin-Charged Turbo Kit for 02-06 Cooper S
|
 |
 |
| Alta's twincharger 'TWURBO' kit offers Mini Cooper S owners a buddy to complement to their supercharger; the Garrett GT3071R turbocharger. The Alta Mini Performance Twin-Charged Turbo kit for the Mini Cooper S features a Garrett GT3071R turbo capable of producing up to 400 horsepower! Mounted low in the engine bay, the turbocharger has plenty of clearance at the firewall and does not interfere with any underhood components. The kit includes a 304 stainless steel tubular header and downpipe. The downpipe scales begins at 2.5" behind the turbo, scales up to 3", and the scales back down to 2.5" to meet a stock exhaust or any other direct replacement system. A 5-layer silicone intake hose and foam filter feed the turbocharger. The 3" silicone intake delivers air smoothly, gradually scaling up to meet the huge 4" turbo housing inlet. The system includes polished aluminium pressure pipes with an attached Alta vent-to-atmosphere blow-off valve to relieve strain on the turbo and throttlebody during shifts; while also letting everyone know you have a turbo. |
 | Alta includes a 5% larger supercharger pulley in the kit to reduce the supercharger boost output. By pushing more boost through the turbo and less through the supercharger, the kit increases in efficiency and produces more power reliably. The basic kit consists of everything needed to bolt the turbo to the car and allow it to run 16psi; a GT3071R ball-bearing turbo, polished stainless steel manifold , downpipe, oil and coolant lines, fittings, pressure pipes, silicone intake hose, foam air filter, air box, fresh air pipe,blow-off valve, and all couplers, clamps, nuts, and bolts. |
| Alta's kit is designed for use with the stock ECU and fuel injectors. The low boost setting makes this kit safe to run wihout an upgraded ECU, but an upgrade is always suggested. A fuel computer such as the Turbo XS D-Tec or the Apexi SAFC are both simple options for fine-tuning your fueling. For those looking to take things further, Hydra EMS and Alta have developed a Standalone Engine Management system designed for use with this kit. For tuners with the Hydra EMS and larger 550cc Alta injectors, pre-tuned maps tuned to higher boost levels for increased performance will be available.

With the base kit on the stock ECU, your factory internals will be up to the task of powering your twin-charged mill. However, if you choose to go the Hydra EMS route and increase boost pressures, you should consider pistons and rods for increased reliability and performance. Alta has various injector options for those pushing the kit beyond base levels; you can send your stock units in to be modified to flow 550cc, or you can purchase new stock injectors that are pre-modified from Alta to reduce vehicle downtime. |
|
The factory intercooler is adequate for the base kit, we recommend upgrading it however, for increased performance. With any increased boost or tuning, a larger intercooler is a must. |
All that being said, this is an excellent way to boost the performance of your Mini Cooper S safely and reliably. The Alta Twurbo kit is designed as either a bolt-on performance upgrade for the average enthusiast, or as a starting point for the tuner looking to push the Mini Cooper S to very limits of its potential.
