The first turbo E90/E92 M3 build that we know of is underway. There are currently several supercharger kits for the M3′s S65 motor available on the market, but no turbo kits, yet. The S65 makes it difficult to place a turbocharger kit’s plumbing, and some tuners are also wary of turbocharging the S65 due to its aluminum construction.
But, South African tuning shop SAVSPEED has taken up the cause and its S65 turbo build is currently in the works. They’ve decided on a single turbo setup. As plumbing is difficult in the S65 engine compartment, a custom engine mount had to be designed. SAVSPEED has already run the turbo’d E92 M3 for 140km on the dyno and all is going well. … CONTINUED
Turbochargers are a popular technology in the automotive world as of late. It allows rather low displacement engines to have relatively high power outputs, while also managing to return fairly good fuel consumption figures (on paper).
Despite the technology being decades old, some of its drawbacks could still be improved upon. One of these issues is the well-known problem of turbo size. A smaller turbine spools up quicky but runs out of steam at higher revs while a bigger turbine offers enough power at high revs but often is too slow at lower revs which results in turbo lag.
BMW has now patented its own idea on how to address these issues, and it involves the use of an often rumored “electric turbocharger”.
We reported before that BMW has … CONTINUED
