Now available through Redline Sportscars, this comprehensively engineered turbocharged MX-5 represents a properly executed fast road build — developed as a complete package rather than simply a power upgrade.

Finished in A5 Satellite Blue with gloss black hard top and detailing, sitting on OZ Ultraleggeras, the car presents with a clean, understated aesthetic. Underneath, however, is a serious specification.

Engine & Turbo System

The proven 1.8 BP engine has been turbocharged via a TIG-welded log manifold and breathes through a full 3” fabricated exhaust system with rear silencer (98db compliant).

Supporting modifications have been carried out correctly to ensure reliability and consistency:

• Bosch EV14 550cc injectors

• Walbro 190lph in-tank fuel pump

• Larger throttle body

• AN oil and water feed/return lines for turbo

• Boost regulator

• Front mount intercooler with proper ducting

• Fabricated charge pipework

• Mishimoto aluminium radiator

• Cooling re-route

• Thermostatic oil plate

• 13-row oil cooler with ducting

• BOFI uprated clutch

Engine management is via a Motorsport Electronics ECU, professionally mapped to produce 190hp at the wheels on wastegate spring pressure. The delivery is strong, responsive and highly usable — with excellent mid-range torque.

Transmission & Differential

• 5-speed gearbox fitted

• 6-speed gearbox supplied with the vehicle

• 4.1 ratio differential

• Type 1 Torsen limited slip differential

The shorter 4.1 final drive complements the turbo torque curve perfectly, delivering urgent in-gear acceleration while maintaining drivability.

Chassis & Geometry

Significant attention has been given to handling and geometry:

• HSD coilovers

• Steering rack riser blocks (bump steer correction)

• Whiteline front anti-roll bar with adjustable drop links

• Rear anti-roll bar removed

• Rear lower arms converted to spherical bearings at the hub

• Rear upper hub bush converted to spherical

• Front strut brace

• MR2 rear hub flange conversion (not fitted)

The spherical rear conversions are a notable upgrade, maintaining geometry under load and providing increased rear stability and traction when driven hard.

Braking System

The braking system has been upgraded to match performance levels:

• Bias-adjustable pedal box (driver adjustable)

• Porsche Boxster front calipers

• G60 front discs

• CL6 and road pad options

• Freakyparts rear sport disc conversion

• Mintex 1144 rear pads

• Bronze rear caliper bushes

• Braided brake hoses

Pedal feel is firm and adjustable, with excellent consistency.

Interior

Driver-focused and purposeful:

• Fixed-back bucket seat (driver)

• Genuine Takata harness

• Roll bar

• Motamec Prototipo-style steering wheel

• Sterling wheel spacer

• Boost pressure, AFR, oil temperature and oil pressure gauges

• Radio delete

Exterior

• A5 Satellite Blue paintwork

• Gloss black hard top, ducktail and windscreen surround

• Firefly rear overfenders (body colour)

• Firefly ducktail (included, not fitted)

• OZ Ultraleggera 15×7 ET37

• 20mm spacers front and rear

• Offset number plate

The overall stance is balanced and cohesive, retaining the character of the original car while subtly enhancing its presence.

Summary

A genuinely well-engineered turbo MX-5 producing 190whp with supporting modifications across fuelling, cooling, braking and chassis systems.

A fast, usable and mechanically sorted example, offered in excellent overall condition.
