Toyota Chaser Guide & Tuning

Toyota Chaser Guide, Tuning & Servicing

1JZ-powered icon — from clean bolt-on builds to big turbo conversions. We specialise in JZX chassis setup, parts supply and in-house fitting for reliable, repeatable power.

  • JZX90Early chassis (1992–1996)
  • JZX100Classic 90s Chaser
  • JZX110MK11 platform
  • ~400 bhpProven fast-road setups

From stock refresh to fast-road power — we’ll build the right plan for your Chaser’s current spec and goals.

Chaser tuning — done properly

The Toyota Chaser is one of the best-value JDM performance platforms: strong 1JZ engines, great chassis balance, and huge parts support. The key is doing modifications in the right order — baseline health first, then bolt-ons, then supporting mods for the next step.

  • JZX90 — older imports benefit hugely from a proper baseline refresh
  • JZX100 — fast-road bolt-ons, intake/exhaust and turbo upgrades
  • JZX110 (MK11) — refined daily/fast-road builds with strong power potential
  • Supply + fit: cooling, fueling, ECU strategy, drivetrain and chassis upgrades
  • Reliable mapping strategy with a focus on repeatable results

Real-world examples

JZX100 · bolt-ons

~400 bhp fast-road setup

This JZX100 came in for sensible bolt-on upgrades and left with a strong, responsive setup — around 400 bhp. Perfect for a quick road car that stays drivable and reliable.

  • Carefully chosen intake/exhaust improvements
  • Health checks and supporting service work
  • Calibration strategy for safe boost and repeatable power
JZX110 · 395 bhp

MK11 build with strong midrange

Our MK11 JZX110 example produced 395 bhp — a great “sweet spot” for fast-road performance while keeping OEM manners.

  • Matched parts list (no guesswork)
  • Focus on response and midrange torque
  • Supporting mods to keep temps and fueling under control

Beyond the bolt-ons — what’s next?

Once you’ve completed the basic bolt-on route, the next step is choosing how you want the car to drive: sharper response, more top-end power, better traction, or a full conversion. We can supply and fit everything in-house and tailor the plan around your use (road / fast road / track).

Turbo & airflow

Bigger turbo / conversion planning

  • Turbo upgrade selection matched to your goal
  • Manifold + wastegate setups, downpipe and exhaust routing
  • Intercooler upgrades and hard pipework for consistent IATs
  • Boost control refinement and supporting intake solutions
Fueling & ECU

Support higher power properly

  • Fuel system upgrades (pump/injectors/lines as required)
  • ECU solutions and calibration strategy for safe, repeatable power
  • Datalogging, health checks and ongoing optimisation
  • Knock/AFR monitoring for long-term reliability
Cooling & reliability

Keep it consistent

  • Radiator, fans, thermostat and hose refresh
  • Oil cooling solutions for sustained boost / track use
  • Boost/vacuum leak testing and ageing component refresh
  • Ignition system health for higher cylinder pressure
Chassis & brakes

Make it feel modern

  • Brake upgrades, pads/lines/fluid and big-brake solutions
  • Coilovers/suspension packages, bushes and geometry setup
  • Wheel/tyre setup advice for traction and stability
  • OEM+ refresh: arms, ball joints and anti-roll bar links

Restoration & age-related maintenance

Chasers are now classic JDM imports — and the biggest performance upgrade is often a proper refresh. We see the same ageing issues across JZX90/JZX100/JZX110 platforms: tired bushes, corroded hardware, worn suspension arms, neglected cooling systems, and driveline components that have done decades of work.

Whether your goal is OEM+ refinement or a 400bhp+ fast-road build, starting with a solid base makes the car faster, safer and more enjoyable — and it avoids chasing issues later once boost and heat go up.

  • Rear subframe, suspension arms and subframe mount bushes
  • Diff bushes, propshaft couplings and driveline mounts
  • Fuel and brake lines, handbrake cables and underbody protection
  • Cooling system refresh: radiator, hoses, thermostat, fans
  • OEM+ brakes/suspension for confidence on the road

We don’t have a dedicated Chaser restoration photo set yet — below are examples from our Supra restoration work showing the same type of underside refurbishment and protection we carry out.
