Olsen Motorsports

Olsen Motorsports is a Porsche restoration and service shop in Downers Grove, Illinois, focused on air-cooled cars, mainly the 911 family. The shop says it was established in 2015. It works on engine rebuilds, full restorations and custom builds, and says it takes clients from across the country.

Who they are

The shop is at 2300 Wisconsin Ave, Unit 105, Downers Grove, IL 60515. A third-party directory also lists a Naples, Florida location, though we could not confirm that on the shop's own site. The site names no owners in the pages we could read.

What it restores

Olsen concentrates on air-cooled Porsches, with emphasis on the flat-six cars built after 1972. It lists 911, 930, 964 and 993 generations in its restoration work. The shop describes projects ranging from show quality restorations to restomods, mechanical rebuilds to original specification, and track or outlaw builds.

Work done in-house

The shop says its capabilities include metal shaping and fabrication, mechanical restoration, engine building, suspension work using JRZ components, body and paint work, electrical systems and custom upholstery. It also lists tiers of engine rebuild: an OEM rebuild, an Olsen Art and Performance engine, and an Olsen Defined engine.

Restoration tiers

Its site sets out three levels of restoration. The OEM Light Restoration covers the engine, paint, interior and suspension and takes roughly three to four months by the shop's estimate. The Olsen Mod adds selected performance, drivability and comfort upgrades. The Olsen Signature Collection is a fully bespoke build that the shop says typically takes 12 to 14 months. These are the shop's own timelines, so confirm them against your car.

Working with the shop

The shop says it relies on constant communication, structured approvals and extensive photo documentation, including for out-of-state clients. Pricing is not published. For help planning questions before you call, read how to choose a restoration shop.
