Ready to take your B58 to the next level?

Don’t want to deal with core charges, long lead times, or restrictive factory housings? Look no further! VTT has you covered with our 100% new casting B58 GC and GC+ turbocharger upgrades. We start with keeping the great design elements of the factory B58 turbo and removing the not-so-great ones such as the small factory inlet area, bearing housing oil structure, thrust bearing, and anything else we saw that could be improved upon. With the basics covered, we stepped it up a level adding in proprietary VTT changes and finished off by having all these parts cast to OE quality. What this means for you is serious B58 power made easy; GC’s are a drop in B58 turbocharger core upgrade that supports over 600WHP (550bhp-580bhp in the UK) while maintaining factory spool and all factory connections including oil, water, downpipe, and charge pipe.

The GC is supplied as the core which bolts directly into the OE manifold. It features a 9 bladed turbine wheel on the other end of a 9-bladed compressor wheel which is Mar-M 246 aero engineered and point-milled to maximise air flow and eliminate compressor surge. The GC+ is also newly cast core, as well as a fully cast VTT manifold which is much, much bigger than the original OE manifold, so unlike the GC which bolts to the OE manifold, the GC+ is a complete assembly that replaces the old turbocharger completely. It has a bigger version of the 9 blade turbine wheel, and a whopping 10 blade compressor wheel, featuring the same amazing design Mar-M 246 aero engineering and point-milling. The GC turbo will make 550-580bhp with a B58tu fuel pump depending on your mods and dyno, and the GC+ will make 700bhp with a Dorch Stage 2+ fuel pump, again mod dependent and dyno dependent.

At GC+ level we also recommend forging your engine with the B58R complete forged engine unit that we have available and in stock, complete with forged pistons, rods, new gaskets and assembly consumables. What do the the options mean? The two options on this product are for the airbox connector and fitting kit. For the airbox connector, you only need this if you are running the standard airbox. For an aftermarket airbox, the silicone hose intake that comes included with the turbo will be fine. For the fitting kit, we highly recommend purchasing the extra fitting kit with your turbo. It includes a new gasket and fire ring, which ensure you won't have any leaks of exhaust gas for both power and safety, and all mounting hardware and bolts. We purchase this kit straight from our local BMW dealer so we can give you the reassurance that they are 100% genuine BMW parts. Why should I buy the vargas turbo? The Vargas turbo is for the serious tuner. At the point where you want 500bhp, we can offer stage 2 mapping with all the hardware and fitting. We offer MAXD Out remapping software which we write here ourselves, and we are now a registered supplier of bootmod3 licenses, so we can offer the OTS maps from this platform too. A nudge past 500bhp and the X37 hybrid turbo can take you to 530bhp; a quickspooling turbo that offer serious performance an even challenges Mclaren's on track days.

But the Vargas turbos for the B58, these take you to a new level of performance. With Mar-M 246 aero engineered blades that have point milling to flow more air and eliminate compressor surge, the VTT range of turbos are designed to a specification that you expect to see on racecar blueprints. The GC turbo will take you to 580bhp with a Dorch stage 1 pump and all the right mods. This is crazy big power and would have been more than enough for our track spec M240i that we have here at Pumaspeed. The GC+ 700bhp turbo however is completely in a league of it's own. We're putting one on our car... because we can! Dorch stage 2 pump, turbo and mapping on top of our B58R forged engine, and we will have a 700bhp tap of pure awesomeness at our disposal. If you want power, you want Vargas. See the video below which takes a more detailed look at the two turbos side by side.
