I helped the owner install VEMS engine management on his BMW E34 535 turbo about four years ago, and he's been using it ever since as a daily driver. .
The latest hardware upgrade was a Dbilas 308 cam and M5 separate throttlebodies. The head has been ported, lightening of the stock valves, stronger valve springs, IE heavy-duty rockers. The bottom end is completely stock and a standard gasket is used with ARP studs, and no O-rings. Other than that the turbo is a Holset HX50 (63 mm inducer) which is mounted on an adapter to the two stock exhaust manifolds with pulse-split function, charge air is cooled by a larger air-air intercooler, fuel through two in-tank mounted pumps and 788 cc/min injectors, and CDI spark using the stock distributor ignition system.
It breathes pretty good, best so far on a Dynapack: 607 whp @ 6800 rpm / 1.33 bar. All tuning and driving with 95 RON octane gasoline.
Hver segir svo að M30 geti ekki staðið sig !!
