Heritage by Crawford Performance — full lockup

It started in the dirt.

Crawford Performance was founded by Quirt Crawford — a sand-rail engine builder out of the Glamis dunes who crew-chiefed for Tim Allen's Saleen program and became one of the best MoTeC tuners in the business. When the WRX finally came to America in 2002, he had the platform he'd been waiting for.

Over 30 years later, the rule that built the name still runs the shop: don't fix what isn't broken, and prove everything on track.

The record, in short

Gymkhana

In 2008, Crawford built Ken Block's STI for DC Shoes' Gymkhana Practice. The video rewired car culture overnight. Gymkhana Two: The Infomercial followed in 2009 — Crawford-built again.

The parts from those cars never went out of production. The Gymkhana One exhaust is still built today, to the original spec.

Tony the Tiger

Subaru of America came to Crawford with a brief: build the fastest new-age STI in the world. The answer was an orange GRB with roughly 850 horsepower, driven by Eiji “Tarzan” Yamada.

At Buttonwillow in 2009 it set a 1:45.552 lap that Super Street was still listing in its all-time records in 2016. The car lives at our East Coast facility today.

The Desert Years

In 2017 Subaru launched its first factory desert program — and put a Crawford-built car at the center of it. The Crosstrek Desert Racer, a Class 5 Unlimited buggy running a Crawford-built 2.5-liter boxer, won its class five times in three seasons and made Crawford a factory team for the second time.

That program runs in the Crawford Baja line today.

The Invention

Quirt Crawford invented the air/oil separator for Subaru — the first one, and still the reference every later design is measured against. It stays closed, it drains back, and every EJ car still needs one.

We still make the original.

Why every Subaru engine needs one

Every result is a matter of record.

Wins, podiums, factory programs — each one checked against a sanctioning body, a factory release, or the press that covered it at the time.
