Crawford Performance Reviews: What Our Track Record Actually Shows

If you're researching Crawford Performance before placing an order — good. That's exactly what you should do before spending real money on an engine build. Here's what actually backs the name.

Founded in 1993, still building.

Crawford Performance has been building Subaru performance parts and engines since 1993. Three decades in a niche as specific as Subaru tuning doesn't happen by accident — it happens by building parts that work, repeatedly, for an audience that talks to each other constantly in forums, at meets, and on track days.

The only aftermarket tuner trusted by Subaru of America.

That's the hardest credential to fake. It's a relationship few shops in this industry ever earn, and it didn't come from a press release — it came from engineering work that held up.

Built for Ken Block's Gymkhana cars.

Crawford built the engines for Ken Block's Gymkhana 1 and Gymkhana 2 — the rally videos that introduced an entire generation to what a built Subaru could do. That's not a sponsorship logo. That's an engine that had to survive professional-level abuse on camera, repeatedly, with no room for failure.

Every engine starts from a new OEM Subaru block — not your worn-out one.

Here's the part that actually matters for your build: most engine builders start with a "core" — your old block, or someone else's used block, with an unknown history of miles, heat cycles, and prior damage. You're paying someone to gamble on what's hiding inside metal they didn't watch get used. Crawford starts every build from a brand-new OEM Subaru block. Zero prior miles. Zero prior damage. Zero unknowns. No core charge, no core deposit, nothing to send back.

Backed by a 1-year, unlimited-mileage warranty.

On a part that, by definition, gets driven hard. That's a real commitment, structured that way on purpose.

What we can tell you is what's actually verifiable: three decades in business, a Subaru of America relationship that's rare in this industry, a motorsport pedigree built on real engines in real cars, and a build process that starts clean instead of gambling on a used core. That's not marketing copy — it's the standard we hold every build to.
