Everything at Phoenix Speed Industries happens under one roof in Peoria, Arizona: the engine is built here, the wiring and engine management are done here, and the car is tuned on our own dyno here. No shipping the short block across the country, no sending the car somewhere else for the tune, and no finger-pointing between shops when something isn't right.


We build engines for race cars, drag cars, and street cars with serious power. Audi and Lamborghini V10s, Nissan GT-R VR38s, Ford Coyote engines, as well as a few others.
Every build is measured, documented, and assembled to spec, and every clearance and torque value is recorded so the engine can be serviced correctly later.

MoTeC is our specialty, and Phoenix Speed Industries is an authorized MoTeC dealer. We supply, wire, configure and calibrate MoTeC systems.

Not every car needs a standalone. We calibrate factory ECUs on BMW, and soon Ford F150 platform.

We tune on our own Mainline hub dyno. A hub dyno bolts to the hubs instead of spinning rollers, so there is no tire slip.

Dealer-level factory diagnostics for Lamborghini, Audi and VW. If a car has a problem nobody else can find, that's usually where we start.

Pre event inspections, teardown inspections on race engines, fluid and safety checks, and the setup work that keeps a car from breaking on race day. If you are starting or rebuilding a race program, we can put the systems in place for it, from data logging and maintenance schedules to spares and inspection routines, and consult on the program as a whole.

We are developing a full program on our own shop car, with the engines built in-house. Details as the program comes together.

Same approach: our own shop truck is the development vehicle, and the engine is being built in-house.
Call (623) 248-5209 or send us the details through our online work request. Tell us the year, make and model, what's been done to it, what engine management it runs, and what you want it to do. You can attach photos or video to the request too.
