Rossi Engines did an excellent job in repairing my LS2, which was suffering from low compression.From start to finish, their communication was clear, and they kept me updated on the progress throughout the repair process. The team demonstrated a deep understanding of the LS2 platform, diagnosing the issue quickly and offering a full rebuild.It ended up being quite complex with CNC ported heads & forged internals, this was completely managed and installed by them.The workmanship was top-notch, and the engine is now running better than ever. I’m really satisfied with their service and would highly recommend Rossi Engines to anyone needing professional service and reliable engine repairs.

I was recently traveling back to the city in my M-sport BMW from a nice drive in the southwest via Kelmscott at such time warning dash lights appeared, and I suddenly pulled over and my #GoogleMaps #LocalGuides skills were in play. I "search" find a mechanic nearby me, 1st suggestion I see the name, "Rossi Engines appeared" I arrived there soon after I quickly ask him my car needs attention, he says no worries. Connected up some intricate diagnostic equipment and chased a wiring fault and repaired it while I waited. I rate this business 5 stars for immediate mechanical help, thank you Rossi Engines

I recently had a fantastic experience with Rossi’s. They truly set themselves apart with excellent communication and prompt responses. After calling three different businesses for quotes, they offered the best price and even followed up with a call back about specific request I had. Highly recommend for their professionalism and great value, will be back for my logbook servicing in the future.
