2.2 L I4 · Turbo Z
The 1985 Dodge Daytona Turbo Z is a front-wheel-drive sports coupe built on Chrysler's K-car platform — the L-body. It was Dodge's attempt to bring affordable turbocharged performance to the American market during a lean decade for muscle cars. The Turbo Z trim topped the Daytona lineup, pairing the turbocharged 2.2L four-cylinder with a firmer suspension tune, rear spoiler, and sportier interior appointments. For its era it was genuinely quick, and the turbo 2.2 engine became a cult favorite among Mopar enthusiasts. Handling was above average for an American FWD coupe of the mid-1980s, and the low, wedge-shaped body held up stylistically better than many contemporaries. At nearly 40 years old, any surviving Daytona Turbo Z is firmly a collector or hobbyist vehicle. Parts availability has thinned considerably, turbo and fuel system components require patience and know-how to source, and the cars demand an owner who is either mechanically inclined or has access to a shop that knows vintage Mopar.

Maintenance schedule
- 1 Every 3,000–4,000 miles or annually, whichever comes first Change engine oil with a quality conventional or synthetic oil rated for turbocharged engines
Turbo bearings are oil-cooled; degraded oil accelerates turbo wear dramatically. Short intervals are cheap insurance on a 40-year-old turbo.
- 2 At purchase and every 4–5 years Inspect and replace all rubber fuel system components (hoses, injector o-rings, fuel rail seals)
Original rubber is 40 years old. Cracked hoses near the turbo are a fire hazard.
- 3 Annually and before any spirited driving Inspect intercooler hoses and boost tubes for cracks and soft spots
Boost leaks cause rich/lean surges, hesitation, and can destroy the turbo through lean conditions.
- 4 Every 2 years Flush and replace coolant
Depleted coolant accelerates aluminum corrosion in the head and water pump. Overheating a turbo 2.2 is a very expensive mistake.
- 5 Every 30,000 miles or 2 years Replace spark plugs and inspect plug wires
The turbo 2.2 is sensitive to ignition condition. Aged wires cause misfires that are easy to misdiagnose on early electronic fuel injection.
- 6 Annually — especially before winter storage Inspect and lubricate door, hatch, and chassis rubber weatherstripping and seams
Cracked seals let water into the floor pans, accelerating rust from the inside out.
- 7 Every 30,000 miles or 3 years Check transmission fluid (manual gearbox)
The Getrag/A520 5-speed units are hard to source; fresh fluid extends synchro life.
- 8 Every 3–4 years or if showing any weakness Inspect and replace the battery before winter storage
Cold cranking a turbocharged engine in Wisconsin sub-zero temps with a marginal battery is a recipe for a no-start and potential fuel system flooding.
Always defer to the manufacturer's service manual for warranty-mandated intervals.
Cost of ownership
Annual maintenance
$600 – $2,500
Fuel
Premium gasoline recommended. At ~19 mpg combined and ~10,000 miles/year, expect roughly $900–$1,100/year at current Midwest prices.
Insurance
Classic/collector car insurance is strongly recommended and is typically $200–$600/year through specialty insurers, far cheaper than standard policies on a vehicle this age.
This is not a cheap car to keep running. Parts are scarce and increasingly expensive; a single turbo replacement or rust repair can push annual costs well above the car's market value. Budget generously for deferred maintenance when buying. The reward is a genuinely unique driver that costs very little to insure as a collector vehicle.
Seasonal care
Lake Geneva, WI Winter
- Store the vehicle if at all possible — Wisconsin road salt is the single greatest threat to a 40-year-old unibody. Even one salted winter can undo years of rust repair.
- If driving in winter is unavoidable, rinse the undercarriage thoroughly after every salt exposure, paying special attention to rocker panels, frame rails, and wheel wells.
- Use a quality battery tender during storage. Cold temps and age-related battery drain will leave you stranded.
- Before storage, fill the fuel tank and add a fuel stabilizer to prevent phase separation and varnish buildup in the injectors and fuel rail.
- Allow a longer warm-up period before driving in sub-zero temps to ensure the turbo receives full oil pressure and flow before boost is applied.
- Check and top off washer fluid with a -20°F or lower rated fluid; original washer nozzles on these cars are difficult to replace if they crack.
Summer
- Monitor coolant temperature closely — heat soak in stop-and-go traffic stresses the turbo cooling system. Allow a 1–2 minute idle-down after hard driving before shutting off the engine.
- Check tire pressure weekly in summer heat; fluctuating temps on aged tires (especially if original or old replacements) increase blowout risk.
- Inspect the A/C system — the R-12 refrigerant this car used from the factory is no longer available; it has almost certainly been converted to R-134a or needs to be. Confirm the conversion was done correctly.
- Check coolant level and condition before any long summer trip; heat + old coolant = head gasket problems.

Red flags
- Any rust perforation through the floor pan or rocker panels — structural repair on a 40-year-old unibody is expensive and rarely done well
- Blue or white exhaust smoke — points to turbo seal failure or head gasket breach
- Evidence of overheating (stained overflow tank, warped header area, blown head gasket history)
- Fuel smell in the engine bay — aged fuel lines or injector seals are a fire risk and must be addressed before driving
- Non-running car sold 'as-is' without a known reason — diagnosing a dead 1985 Chrysler FI system is a specialist job
- Obvious bondo or undercoating freshly sprayed on the undercarriage (seller hiding rust)
What to inspect
- Entire undercarriage for rust perforation — probe the rocker panels, floor pans, and rear subframe with a pick tool; bondo and undercoating can hide severe rot
- Turbo unit: check for shaft play, oil leaks at the turbo housing, and blue smoke on acceleration or deceleration
- All rubber fuel lines from the tank to the engine bay — look for cracking, swelling, or seepage near heat sources
- Intercooler hoses and clamps for cracks; squeeze each hose and look for split areas
- Cooling system: check for a milky residue on the oil cap (head gasket), coolant color (brown = neglect), and any signs of past overheating on the head
- Early electronic fuel injection sensors — a cold start idle that is rough, surgy, or requires pumping the throttle points to MAP sensor or coolant temp sensor issues
- Body seams around the hatch, C-pillars, and drip rails for rust bubbling under paint
- Documented maintenance and ownership history — the fewer owners and the more paper trail, the better
