CTS TURBO STAGE 2+ TURBOCHARGER UPGRADE FOR F97/G80 BMW X3M/X4M/M2/M3/M4 WITH S58 ENGINE

DESCRIPTION

CTS Turbo is excited to announce the release of our latest Stage 2+  designed specifically for the BMW S58 platform. This kit builds on the success and knowledge for the previous turbo projects we have made and incorporates new technology to optimize performance and maintain factory fitment.

Our engineers utilized transient flow analysis and flow bench testing to optimize the twin scroll turbine housing, while maintaining stock fitment, stock location, and using the stock wastegates. This allows for the use of any stock fitment downpipes, intakes, and charge pipes. The result is an impressive 825whp-900whp. You can simply transfer your factory wastegate controllers, high performance downpipes, intake and charge pipes during the install. No custom parts are needed and all factory installation hardware and gaskets are used!

No need for cores to be sent in or purchased.

Each turbocharger is VSR balanced to exceed OE tolerances with upgraded heavy-duty journal bearings and thrust washers.

Our turbochargers are designed to move a lot of air at lower boost levels, which means you can make some serious power without over-speeding the turbos, which means reliable performance.

Further performance can be gained using larger turbo inlets with this setup.

Features:

• Complete brand-new set of 2 turbochargers; no need for core to be sent it or purchased.
• Bolt-on journal bearing CHRA with HD bearings, turbine shaft diameter increased by 1.0mm and thrust surface increased by 2mm.
• Billet – blade compressor wheel, 53.0mm inducer, 70.0mm exducer with 72.6mm extended tip design.
• 9 blade Mar-M 246 Superalloy turbine wheel, 52mm inducer, 49.4mm exducer, high-flow.
• 316 stainless steel exhaust housings and wastegate components, the housing size was increased to allow for optimal exhaust flow. Which mean faster spool and less WGDC required.
• VSR Balanced to exceed OE tolerances
• Compatible with factory installation hardware (not included)
• Compatible with factory wastegate actuators (not included, use your original wastegate actuators). ACTUATORS MUST BE CALIBRATED WITH ISTA+ BEFORE USE. 90% WGDC MAX.

Fitment:

• G80 BMW M3/M3 Competition S58
• G82 BMW M4/M4 Competition S58
• G87 BMW M2 S58
• F97 BMW X3M/ X3M Competition
• F98 BMW X4M/ X4M Competition

NB: professional installation and tuning are required. Break-in period required. Custom tuning using Bootmod3, as well as additional components such as fueling, and charge air cooler upgrades are required.
