The 512 TR was in most people's opinion the best looking version of the mid-engined flat-12 line which began with the 365GT4 BB and ended in 1995 with the F512M. The 512 TR was produced from 1992-1994 and boasted many major improvements over the Testarossa:
Engine:
1. Bore and stroke of 82mm by 78mm, 4942 cc capacity (unchanged)
2. HP increased from 380hp SAE to 421, with most of the increase coming from a redesign of the intake manifolds, a repositioning of the injectors, and a recalibration of the injectors, and a recalibration of the engine management system, the later controlling the integrated electronic fuel injection system
3. Torque increased from 354lb ft to 360
4. 0-60mph, 5.7 sec to 4.8
5. Top speed- 180mph to 192
6. New cylinder liner manufactured in aluminum with Nikasil coating
7. New pistons due to larger intake valves
8. Increase in compression ratio (10.1 to1)
9. Modified cylinder head gaskets due to a higher compression ratio and a different cylinder head coolant circulation layout
10. Reinforced camshafts of a new profile
11. Valve tappets with a new design bucket and springs
12. New larger diameter intake valves
13. Separate air boxes with individual filters and a dynamic air intake
14. Longer and straighter air intake manifolds
15. Integrated electronic fuel injection system and ignition (Bosch Motronic 2.7) with self-diagnostic capabilities, and with ECU located in the cockpit
16. Double independent submergible fuel pumps
17. Exhaust manifolds with new layout
18. Metallic type pre-catalyst converters
19. Exhaust muffler with resonators and new heat shields
20. Aluminum oil radiator with U circulation and without fan, allowing for better permeability; aluminum tubing
21. Dual copper water radiators with U circulation in series and new aluminum tubing
22. Coolant expansion tank located between intake manifolds
23. More powerful alternator
24. Secondary air pump with new air distribution pattern
Chassis:
Up front, the chassis frame was strengthened around specific points; for example, the steering rack mounts and the front suspension mounts. Highly stressed frame pieces are made of special chromium-molybdenum steel. At the rear, the old engine sub frame has been done away with. To gain a noticeable increase in stiffness, the rear frame was made an integral part of the entire chassis. The engine is now lifted out from above. Around the passenger compartment, the steel platform, rear bench, front and rear firewalls, and pillars are all welded directly to the tubes of the chassis. End result is that chassis flex has been reduced by 25% and torsional rigidity has been increased by 12.5%. Other chassis specifics as noted by Ferrari:
1. Overall weight reduction of 88lbs
2. Lower center of gravity
3. Reduction of unsprung weight
4. Steering points in aluminum alloy
5. New steering column shaft design
6. New steering rack with longer arms and more direct ratios
7. New steering moment offset
8. Bilstein gas shock absorbers with aluminum body and adjustable plate
9. New shock absorber settings
10. Lighter weight springs
Gearbox and Differential
1. Limited slip differential (40%) with reduced axial thrust to increase reliability
2. New transfer gear ratio
3. Strengthened transfer gears
4. New synchronizer pre-loading springs
5. Gear shift lever housing with sliding ball bearings
6. New selector and modified gear shift lever inclination
7. New single plate clutch with reduced inertia and asbestos free clutch linings
8. Entire gearbox and transmission strengthened throughout
Brakes:
1. Larger front discs, 315mm x 32mm, with cross drilled braking surface
2. Larger rear discs, 310 mm x 28mm, with cross drilled braking surface
3. Aluminum calipers with larger pistons: front 44/40mm; rear: 40/36mm
4. New ducts for brake cooling
5. New brake proportioning valve
6. Brake pedal ratio is more direct
7. Redesigned hand brake with reduced application effort
Styling:
1. New trapezoidal shaped air intake scoops on front with prancing horse
2. Body colored front spoiler
3. New profile to the C pillar fins in the rear sections with elimination of vents in sail panels
4. Integral air intake slots added to the engine cover
5. Rear lights are now dual colored and a redesign of the underbumper to change aesthetics of the exhaust system and exhaust outlets
6. Wheels redesigned and increased in size to 8x18 and 10.5x18
7. Interior restyled with elimination of center console and repositioning of the corresponding instruments under the central part of the dashboard
8. Door panels and armrests have been changed
This particular car has been driven and enjoyed. It recently had a transmission refresh with a new main shaft, new correct quill shaft, new clutch, and new first gear installed. It also had a full engine out major service, including timing belts, cam seals, gaskets, accessory belts, tensioner bearings, new water pump, A/C recharge, and all fluids and filters. Both of these services were done in 2017 and the car has less than 200 miles since the work was done. Receipts for the car are included back to 2006. The Carfax shows a damage report and an insurance company issuing a total loss claim but the car retained a clear title. It was repainted but the extent of the actual damage is not known. It was fully serviced at Ferrari Service of Costa Mesa shortly after the damage and has been driven over 20k miles since then. It shows in excellent condition for the mileage, and having recently been serviced, should pass any thorough PPI with no issues. We welcome and encourage indpendent inspections by a qualified shop.
