The 2007 Toyota Supra doesn't exist—Toyota discontinued the Supra (A80) in 2002 and didn't revive it until 2020 (A90). If you mean a 2007 JZA80 still on the road, you're looking at a 1993-2002 model with 15+ years of age by 2007, facing issues common to aging 2JZ-GTE platforms.
Blown Head Gasket (2JZ-GTE Stock Boost)
Common · high severityTypical onset: 60,000-120,000 mi
Symptoms: White smoke from exhaust on cold start, Coolant loss with no visible leaks, Oil/coolant mixing (milky oil cap residue), Overheating under boost
Fix: Factory torque spec and composite gasket design are inadequate for even stock boost long-term. Proper fix requires ARP head studs and MLS gasket, head resurfacing, and timing belt/water pump while you're in there. 18-22 hours labor if no head warpage.
Estimated cost: $2,800-4,500
Spun Rod Bearings (High-Mileage or Modified Engines)
Occasional · high severityTypical onset: 100,000+ mi or any mileage if boosted beyond stock
Symptoms: Metallic knocking at idle that increases with RPM, Low oil pressure at operating temp, Metal shavings in oil filter, Sudden catastrophic failure under load
Fix: 2JZ rod bearings wear, especially cylinders 5-6. If caught early, can re-torque and replace bearings with crank polish (12-16 hours). If spun, needs full bottom-end rebuild or short block replacement. Machine work adds cost.
Estimated cost: $3,500-8,000
Automatic Transmission Oil Cooler Line Failure
Common · medium severityTypical onset: 80,000-150,000 mi
Symptoms: Transmission fluid leak near radiator, Pink/red fluid dripping under engine bay, Transmission slipping or delayed engagement after leak develops, Coolant contamination in trans (if internal cooler fails)
Fix: Rubber lines and crimped fittings deteriorate. Replace with braided steel lines and external cooler to prevent catastrophic mixing. 2-3 hours labor if just lines, add 4-6 hours if transmission needs flush from contamination.
Estimated cost: $400-1,200
Fuel Pump and Filter Clogging (Ethanol and Age)
Occasional · medium severityTypical onset: Any mileage on 15+ year old car
Symptoms: Hesitation or stumbling under hard acceleration, Lean fuel trims on scan data, No-start or extended cranking when hot, Fuel pressure drops under load
Fix: In-tank fuel filter screens and 20+ year-old pumps fail. Sock filter clogs, pump impellers wear. Drop tank, replace pump assembly and inline filter. 3-4 hours labor. E85 conversions accelerate failure.
Estimated cost: $600-1,000
Transmission Mount Failure (Manual and Auto)
Common · low severityTypical onset: 60,000+ mi
Symptoms: Excessive shifter vibration at idle, Clunking when engaging clutch or throttle transitions, Visible sagging of transmission tail, Driveline vibration at highway speeds
Fix: Rubber deteriorates, especially rear trans mount. Aftermarket polyurethane mounts add NVH but last longer. 1.5-2 hours labor for rear mount, 3-4 hours if doing all mounts.
Estimated cost: $300-700
Crankshaft Position Sensor Failure
Occasional · high severityTypical onset: Any mileage on aged vehicle
Symptoms: Intermittent no-start with crank but no fire, Sudden stalling while driving with no warning, Tachometer drops to zero during failure, No stored codes in some cases (fails when hot)
Fix: Sensor on timing cover fails from heat cycling. Common on all 2JZs. Replace sensor and check reluctor wheel for damage. 1-1.5 hours labor, inexpensive part but causes breakdown.
Estimated cost: $200-350
There is no 2007 Toyota Supra, but if you're looking at an A80 Supra from the '90s, expect to spend $2-5K immediately on deferred maintenance unless fully documented—spectacular engine when maintained, but head gaskets and bearings are ticking time bombs on aged examples.
