Nissan Terrano II (R20) is a legendary body-on-frame SUV that still enjoys cult status among off-road enthusiasts. Produced from 1993 to 2006, this car has become a symbol of reliability and off-road capability, but even it requires modernization to suit modern realities. Tuning Terrano 2 can pursue different goals: from aesthetic transformation to transformation into a serious off-road monster.

In this article we will look at all areas of tuning - from simple cosmetic leisure activities to deep processing of the chassis and power unit. We will pay special attention unique features of the R20 model, which are often ignored during modifications, but which can radically affect the result. For example, weak points in the suspension when lifting 3+ inches or the nuances of engine chip tuning TD27T with a turbine.

1. Diagnostics before tuning: what to check

Before spending money on upgrades, be sure to evaluate the current condition of the car. Nissan Terrano 2 - a car with a considerable age, and many of its components may be on the verge of wear. Neglecting diagnostics often leads to the fact that after installation, for example, a lift kit or a powerful turbine, they break down. wheel bearings or CV joints - their resource on the standard machine was already running out.

Here minimum checklist before any tuning:

  • 🔧 Condition of frame bushings and silent blocks (wear more than 30% - a direct path to backlash after the elevator)
  • 🔥 Compression in cylinders (for TD27/TD27T norm - 28-32 bar, below 25 - capital is required)
  • 🛞 Body geometry (check the diagonals: a difference of more than 5 mm indicates frame torsion)
  • 🔋 Condition of electrical wiring (especially important for installing additional equipment)

☑️ Critical diagnostic points for Terrano 2

Done: 0 / 4

Pay special attention rear axle. On Terrano 2 with factory blocker H233B Axle shaft seals often wear out. If you are planning serious off-road tuning, it is better to immediately replace them with reinforced from Nissan Patrol GR - they can withstand heavy loads.

⚠️ Attention: If your Terrano 2 was operated in conditions of severe corrosion (for example, in coastal regions), before the elevator, be sure to check the integrity of the side members. Installing spacers on a rusty frame can lead to it to the fault under dynamic loads.

2. Engine tuning: from chip tuning to swap

Power units Nissan Terrano 2 - this is either an atmospheric diesel TD27 (85 hp), or turbocharged TD27T (100-125 hp). Both engines are known for their indestructibility, but they also have potential for improvement. Let's consider options from simple to radical.

2.1. Chip tuning and ECU firmware

The most budget-friendly way to add power is flashing the electronic control unit. For TD27T this can give an increase of up to 20-30 hp, but there are nuances:

  • 📊 Stock turbine Garrett T25 at high speeds it blows ineffectively - firmware without upgrading the turbine will only give an increase to 3500 rpm
  • ⚡ Increasing boost pressure requires strengthening intercooler (the standard one heats up after 2 runs uphill)
  • 🔥 Risk of pistons overheating with aggressive firmware (solution - installation oil cooler)

For atmospheric TD27 Chip tuning is practically useless - the increase will be a maximum of 5-8 hp. It's better to consider here installation of a turbocharger (more on this below).

2.2. Turbo kits and boost upgrade

If you want real power increase, consider the following options:

Modification Power (hp) Cost (₽) Difficulty of installation
Turbine installation on TD27 (whale from TD27T) 100-110 80 000–120 000 Medium (requires exhaust modification)
Turbine upgrade to TD27T (Garrett T28) 140-160 150 000–200 000 High (needs adjustment of fuel equipment)
Installation common rail (whale from ZD30) 180-200 300 000+ Very high (requires ECU and wiring swap)

The most popular option is to install the turbine on atmospheric TD27. For this you will need:

  1. Turbocharger Garrett T25 (can be used with TD27T)
  2. Intercooler (better from Nissan Navara D22)
  3. High pressure fuel pump (Bosch VE from TD27T)
  4. Reinforced nozzles (e.g. Denso with a flow rate of 220 cc)
⚠️ Attention: After installing the turbine on TD27 necessarily reduce the compression ratio up to 17:1 (standard - 21:1). Otherwise, the risk of detonation at high loads increases significantly. This can be done by installing a thick cylinder head gasket or milling the pistons.
📊 What engine does your Terrano 2 have?
  • TD27 (atmospheric)
  • TD27T (turbo)
  • Gasoline GA16DE
  • Other engine

2.3. Engine swap: best options

If even a turbocharged one is not enough for you TD27T, consider complete engine replacement. Best options for Terrano 2:

  • 🔥 Nissan TD42 (135-165 hp) - direct swap, suitable without modifications to the mounts
  • 💪 Toyota 1HD-FTE (205 hp) - requires adaptation of the gearbox and wiring, but provides a huge power reserve
  • ⚡ Isuzu 4JG2 (150-180 hp) - reliable and economical, but difficult to configure

The simplest swap is TD42 from Nissan Patrol. It is placed on standard mounts, and the box FS5R30A from Terrano 2 compatible with it after minor modifications. The main plus is power 165 hp with a torque of 363 Nm, which is 40% more than TD27T.

Details on the TD42 swap

To install TD42 on Terrano 2 you will need:

- Flywheel from Patrol Y60 (diameter 300 mm)

- Sachs or Exedy clutch for diesel engines (article 3000950010)

- Modification of pallet fastenings (will have to be welded)

- Replacing the fuel tank with a 90-liter one (the standard 65-liter one will not provide the required range)

- ECU firmware for a new engine (you can use a unit from Patrol GR)

3. Suspension tuning: lift, reinforcement and off-road mods

Suspension Nissan Terrano 2 — it is dependent on the front (torsion bars) and rear (springs), which gives excellent cross-country ability, but limits the possibilities for tuning. However, there are several ways to upgrade:

3.1. Suspension lift: spacers vs. complete replacement

The most popular upgrade is increased clearance. Options:

  • 📏 Spacers (2-3 inches) - budget (15,000–30,000 ₽), but worsens handling
  • 🔧 Replacing torsion bars to reinforced (from Nissan Pathfinder R50) - +2 inches, maintains rigidity
  • 🏔️ Complete lift kit (for example, from Old Man Emu) - +4 inches, but requires modification to the steering rods

When lift is more than 3 inches necessarily you need:

  1. Lengthen the tie rod (otherwise the steering angle will be reduced by 30%)
  2. Install camber corrector (standard silent blocks cannot withstand the load)
  3. Replace shock absorbers with gas-oil ones (for example, Bilstein B46-2444)
⚠️ Attention: With a 4+ inch lift be sure to strengthen the spring fastenings. On Terrano 2 standard brackets often tear off under dynamic loads (for example, when jumping off-road). The solution is welded ears from Toyota Land Cruiser 80.

3.2. Suspension reinforcement for extreme off-road

If you're planning on serious off-roading, the standard suspension won't be enough. Recommended modifications:

Knot Modification Cost (₽) Effect
Front axle Reinforced balls from Nissan Patrol 12 000–18 000 Resource increase by 3 times
Rear axle Installation difflocker (For example, ARB Air Locker) 80 000–120 000 100% off-road locking
Stabilizers Removable Disconnect Sway Bars 25 000–40 000 Increased suspension travel by 30%

For extreme conditions it is also recommended:

  • 🛡️ Installation crankcase protection (for example, from 4x4 Labs)
  • 🔗 Replacement jet thrust to adjustable (to adjust the geometry after the elevator)
  • 🔩 Strengthening shock absorber mounts (welded eyes instead of standard ones)
💡

Before installing the lift kit, be sure to check the condition spring cups on the frame. On Terrano 2 They are often rusty and can crack as the load increases. The solution is to cut out the old ones and weld new ones from 5mm steel.

4. Transmission tuning: transfer case, axles and gearbox

Transmission Nissan Terrano 2 - one of his most reliable places, but there is still room for improvement. Especially if you are planning serious off-roading or increasing engine power.

4.1. Transfer case modifications

Standard transfer case RL2F has a reduction gear with a gear ratio 2.04:1. This is not enough for extreme offroading. Upgrade options:

  • 🔄 Installation of distributor from Nissan Patrol GR (gear ratio 2.28:1)
  • ⚙️ Replacing gears with Marlin Crawler (options available 2.72:1 And 4.0:1)
  • 🔧 Installation two-stage transfer case (For example, Advance Adapters Atlas 2)

The most budget option is to replace the gears. Set from Marlin Crawler will cost 60 000–80 000 ₽ and will allow you to get a downshift 4.0:1, which is critical for overcoming steep climbs.

4.2. Strengthening axles and differentials

Standard axles Terrano 2 (H233B front and C200 rear) can withstand up to 3.5 tons of load, but with increasing power or extreme off-road conditions they need to be strengthened.

Recommended modifications:

  • 🔨 Installation stockings on the axle shaft (bending protection)
  • 🛠️ Replacement oil seals on SKF or Timken (resource increases 2 times)
  • 🔗 Installation blocking (For example, Detroit Locker for rear axle)

For front axle H233B it is also recommended to replace crosses on Spicer 1310 — they withstand large rotation angles, which is important after the elevator.

⚠️ Attention: When installing the blocker on the rear axle C200 be sure to strengthen his body. A welded difflocker creates additional stress, and a standard cast iron body may crack. Solution - installation steel casing from Nissan Patrol.

5. External tuning: from bumpers to LEDs

Exterior Nissan Terrano 2 can be transformed both in a retro off-road style and in a modern aggressive way. The main thing is not to overdo it with plastic body kits, which will only worsen the geometric cross-country ability.

5.1. Bumpers and protection

Standard bumpers Terrano 2 made of thin metal and cannot withstand heavy loads. Popular replacements:

  • 🛡️ Steel bumpers from ARB or Ironman 4x4 (weight ~50 kg, but full protection)
  • 🔧 Aluminum bumpers (30% lighter, but more expensive - from 100,000 ₽)
  • 🚙 Tubular bumpers (the easiest option, but weak protection)

For the front bumper it is also recommended to install:

  • 💡 winch (the optimal choice is Warn Zeon 10-S with a pulling force of 4.5 tons)
  • 🔦 Additional spotlights (For example, Hella Rallye 4000)
  • 🛂 Protection radiator (mesh or perforated sheet)

5.2. Optics and lighting equipment

Headlights Terrano 2 leaves much to be desired, especially in off-road conditions. Improvement options:

  • 💡 Replacing lamps with LED (For example, Osram Night Breaker Laser)
  • 🔦 Installation additional LED panels on the roof
  • 🌓 Headlight tinting (only permitted! - no more than 30% light transmission)

When installing additional light it is important:

  1. Use voltage relay (For example, Hella 4RA 003 561-001)
  2. Route wiring to corrugation (protection against chafing)
  3. Install anti-glare diffusers (so as not to blind oncoming people)
💡

When choosing a winch for Terrano 2, be guided by the weight of the vehicle when fully loaded (about 2.5 tons). The optimal traction force is at least 4.5 tons (with a reserve for dirt and slopes).

5.3. Wheels and tires

Wheel selection is one of the most important aspects of tuning Terrano 2. Optimal parameters:

  • 📏 Diameter: 31-33 inches (more - only with arch trimming)
  • 🔄 Departure (ET): from +10 to -10 (depending on the width of the disk)
  • 🛞 Disc width: 7–8 inches (for tires 235/85 R16)

The best tire options for different conditions:

Coverage type Rubber model Size Price per piece (₽)
Mud/snow BFGoodrich Mud-Terrain T/A KM3 235/85 R16 18 000–22 000
Stones/rocks Nitto Trail Grappler 245/75 R16 20 000–24 000
Station wagon Goodyear Wrangler Duratrac 225/75 R16 15 000–18 000

When installing wheels more 33 inches you will have to:

  • Trim the arches (or install fenders)
  • Change springs to tougher ones
  • Adjust speed date (otherwise the speedometer will lie)

6. Interior tuning: comfort and functionality

Salon Nissan Terrano 2 simple and ascetic, but it can be made much more convenient. The main thing is not to overload the car with unnecessary accessories that will only add weight.

6.1. Seats and ergonomics

Standard seats Terrano 2 are not comfortable, especially over long distances. Replacement options:

  • 🪑 Sports seats (For example, Recaro SRD)
  • 🛋️ Seats from Nissan Patrol (full mounting compatibility)
  • 🔧 Heating (sets from Webasto or Eberspacher)

Also recommended:

  • Install adjustable steering column (for example, from Toyota LC80)
  • Replace gear knob to shortened (improves ergonomics)
  • Add armrest (can be made to order from aluminum)

6.2. Multimedia and navigation

Modern gadgets can make trips to Terrano 2 much more comfortable. Optimal solutions:

  • 📱 Installation Android radios (For example, Pioneer DMH-ZF9350BT)
  • 🎵 Acoustic system (speakers Focal Access 165 + subwoofer JBL GT-BassPro12)
  • 📡 Walkie Talkie (For example, Baofeng UV-5R for off-road trips)

When installing the radio it is important:

  1. Use can bus for integration with on-board electronics
  2. Route wires through corrugation (protection against chafing)
  3. Install additional fuse at 20A

6.3. Organization of space

B Terrano 2 there is a lot of space, but it is often used irrationally. Useful improvements:

  • 📦 Trunk boxes (For example, Front Runner)
  • 🔧 Tool holders (on the back door or behind the seat backs)
  • 💧 Additional tank (for example, 20 liter under the hood)

Also useful for long hikes:

  • 🔥 Webasto stove (Webasto Thermo Top Evo 5)
  • ⚡ Second battery (For example, Optima YellowTop)
  • 🍳 Gas stove (built into the trunk)
💡

When installing a second battery, use denouement (eg relay VSR from National Luna). This will allow you to automatically turn off the additional battery when the main battery is discharged, avoiding complete loss of energy.

7. Newbie mistakes: what not to do when tuning Terrano 2

Many owners Nissan Terrano 2 make critical mistakes that lead to breakdowns or even accidents. Here are the most common:

  • 🚫 Installing an elevator without suspension reinforcement → rupture of silent blocks after 500 km
  • 🚫 Ignoring wheel balancing → vibration at speeds of 80+ km/h
  • 🚫 Replacing the motor without upgrading the brakes → increase in braking distance by 2 times
  • 🚫 Using cheap Chinese spare parts → breakdowns after 1-2 trips
  • 🚫 Neglecting wheel alignment adjustment → uneven tire wear

Another common mistake is installing wheels that are too wide without trimming the arches. This leads to:

  • Rubbing tires on fender liners
  • Increased load on wheel bearings
  • Poor handling at high speeds
⚠️ Attention: Never install hydraulic locks to bridges Terrano 2 without preliminary strengthening of the axle shafts. Stock axle shafts H233B They break down when blocked already on the second or third run in heavy off-road conditions.

8. Legal aspects: what is possible and what is not

Any tuning must correspond technical regulations of the Customs Union. Otherwise, you may be deprived of your license or prohibited from operating the vehicle. Main restrictions:
