Look no further! VTT has you covered with our 100% new casting B58 “GC” “GC-MID” and  “GC+” turbocharger upgrade. We start by 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 upgrade that supports over 600WHP while maintaining factory spool
