HOW WE BUILD RELIABLE RESTO MODS
A clear, documented process from day one to first drive.
We treat every car like it’s our own—documented, photographed and tested at every stage so you know exactly what’s happening under the sheetmetal.
01 • DISCOVERY & PLANNING
Build around how you actually drive.
Street cruiser, canyon car, drag‑strip bruiser—we spec engine, gearing, suspension and brakes around your real‑world use, not just peak horsepower.
02 • TEARDOWN, MOCKUP & FAB
Clean installs. Serviceable later.
Engine and drivetrain mockup, bracketry, exhaust and cooling routed for clearance & serviceability. We avoid hack‑and‑slash shortcuts that cause problems later.
03 • WIRING, TUNING & TESTING
Modern reliability. Old‑school character.
We looms, standalone ECUs and dyno‑proven tunes so it cold‑starts, idles and cruises like a new car—then hands you the keys with a full shakedown report.
LS & COYOTE SWAPS • STANDALONE ECUS
Modern powertrains, tucked and tuned like they belong there.
Beertech has deep experience dropping late‑model LS and Coyote engines into classic chassis—clean firewall lines, proper cooling, and wiring that looks like it rolled off the assembly line that way.
LS swaps
- NA or boosted combos for street & strip
- Accessory & pulley packages that actually clear
- Fuel systems sized for your future power goals
Coyote swaps
- Clean brake booster & steering shaft solutions
- Factory‑style drivability with serious RPM
- Manual or auto transmission integration
Standalone ECUs & wiring that won’t haunt you later.
We design and build harnesses around Holley, Terminator, Pro EFI and other standalone systems, with proper sensor placement, heat protection and documentation for future service. No spaghetti harnesses, no mystery relays.
CHASSIS • STEERING • SUSPENSION • BRAKES
We can build your old muscle car to the modern era.
Big power is only fun if the car can turn, stop and track straight. We upgrade steering, suspension, drivetrain and braking systems so your classic actually feels like a modern performance car.
- Rack‑and‑pinion steering conversions & tight, on‑center feel
- Coilover and 4‑link setups tuned for your roads and tires
- Overdrive transmissions for highway cruising at sane RPM
- Big brake packages that clear your wheel choice and stop hard
Whether you just want to ditch the floaty steering box and drum brakes, or go full pro‑touring, we’ll design a package that works together as a system—not a pile of parts.
Common upgrade paths we build:
- Stage 1: Steering + front brakes + basic suspension refresh
- Stage 2: Coilovers, sway bars, rear disc and modern wheels/tires
- Stage 3: Full chassis, drivetrain and interior modernization
We can phase the work around your budget and timeline, with each stage fully drivable on its own.

What most owners ask before we tear the first bolt loose.
If you’re new to resto mods and swaps, you’re not alone. Here are straightforward answers based on real projects we’ve already delivered.
How much does a typical LS or Coyote swap cost?
Costs depend on the condition of your car, engine choice, supporting parts and how "turn‑key" you want the finished car. Most complete, reliable swaps we do fall into a broad range, with transparent line items for parts, fabrication, wiring and tuning. During your consult we’ll walk you through good‑better‑best options so you can pick a realistic budget.
Can you phase the work so I don’t do everything at once?
Yes. Many customers start with chassis, steering and brake work so the car is safe and fun, then come back for engine and drivetrain upgrades. We design your build in stages so each phase is fully drivable and doesn’t create re‑work later.
Will my car be reliable enough for road trips?
That’s the entire point of our approach. With modern engines, properly sized cooling, quality wiring, standalone engine management and careful testing, our goal is a car you can jump in and drive hours without wondering if you’ll make it home.
Do you only work on American muscle?
Our bread‑and‑butter is classic American iron—Camaro, Chevelle, Mustang, Nova, trucks and similar platforms—but if you have something interesting, we’re happy to talk through the project and let you know if it’s a good fit.
Questions before you schedule with us?
Here are answers to what we’re asked most often. If you don’t see your question here, send it in the form below!
Do you only work on BMW and GM vehicles?
BMW and GM platforms are our core focus, but we also work on other high-end performance cars including McLaren and modern Porsche, as well as select other platforms on a case-by-case basis. Use the form to tell us what you drive and your goals.
What kind of power gains should I expect?
It depends on the platform, mods, fuel, and how conservative you want the tune. In your intake we’ll outline a realistic power range based on cars with a similar setup that we’ve already tuned.
Can you help me choose parts before I buy anything?
Yes—and it’s one of the best ways to avoid disappointment. We can recommend a combination of parts that work well together and support your target power without over-spending in the wrong areas.
Do you offer remote or email tuning?
Our priority is local in-house dyno and street tuning, but in some cases we’ll support remote calibration for existing customers or specific platforms. Tell us where you’re located and what you’re working with.
