Frequently Asked Questions

We specialize in European vehicles (BMW, Mercedes, Audi, VW, Porsche), JDM imports (Honda, Toyota, Subaru, Nissan, Mazda), exotic vehicles, and American muscle with GM LS/LT swaps. We also handle most domestic vehicles for routine repairs and maintenance.

Yes — LS and LT swaps are one of our signature services. We handle the full build: engine sourcing, custom mounts, wiring harness, cooling, exhaust integration, and getting it running and tuned. We've done swaps across a wide range of platforms.

Call us at (469) 826-6006, email us at info@upspeedgarage.com, or use the contact form on this site. For complex builds like engine swaps, we may schedule a brief inspection to give you an accurate number.

We're located in Terrell, TX and serve Terrell, Forney, Rockwall, Rowlett, Garland, Mesquite, Kaufman, Seagoville, Sunnyvale, Balch Springs, and the surrounding east DFW / Kaufman County area. Many customers drive from the greater Dallas area for our services.

Yes. We have the equipment and experience to diagnose BMW, Mercedes, Audi, VW, Honda, Toyota, Subaru, Nissan, and more — including platforms that require manufacturer-specific scan tools. We go beyond code reading to actual root-cause diagnosis.

Absolutely. Custom exhaust fabrication is one of our core offerings. We work in stainless steel and mild steel and can build to any spec — full turbo-back, cat-back, custom routing, specific tone targets. We can also install bolt-on aftermarket exhaust systems.

Most engine swaps take 1–3 weeks depending on complexity, custom fabrication requirements, and parts availability. We'll give you a realistic timeline at the quoting stage — we don't pad it, and we don't rush it.

Yes — wiring and electrical work is a strength of ours. We build custom wiring harnesses, integrate swapped engines into factory or aftermarket ECUs, and diagnose electrical faults on complex modified vehicles.

Yes — UpspeedGarage is fully insured. Proof of insurance is available on request.

We offer free quotes for most services. For complex diagnostic work, a diagnostic fee may apply — and if you proceed with the repair, it's often credited toward the job.

We accept major credit cards, debit cards, cash, and electronic transfers. Contact us to discuss payment options for larger builds.

Our standard hours are Mon–Fri 9AM–7PM and Saturday 10AM–5PM. For after-hours drop-offs, call us at (469) 826-6006 to make arrangements.
