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
~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
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
Want similar results? Tell us your current spec (turbo, fuel, ECU, gearbox) and your goal — we’ll advise the best route.
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).
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
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
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
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.
