TwinSpark Racing & Engineering is having extensive machinery and the knowledge to provide some exclusive and advanced modification and machining services for Gearbox housings and Engine parts.
Our clients often bring us poorly repaired gearboxes for their classic Porsche 911s and ask for our help. As the numbers of high quality donor gearboxes of the 901 and 915 type are dwindling, it has become time for a solution to save what is left.
TwinSpark specialise in machining these gearbox housings and applying inserts which facilitate the use of the original spec bearings. It takes great skills, precision and high end equipment to perform these restorations. Our engineering crew delivers all that.
Furthermore we supply and/or t custom gear ratios and crown and pinion combinations to tailor gearboxes to the speci cation of our clients. We also supply the parts and machining services needed to retro t 915 gearboxes with RS/RSR oil cooling systems with internal spray bars.
