CTS Turbo Stage 2+ Turbocharger Upgrade for G80 BMW M3, G82 BMW M4, G87 BMW M2 and F97/98 BMW X3M/X4M with S58 Engine
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 790whp to an absolutely staggering 959whp/727wtq.
The best part is that 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.
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
