Experienced Mitsubishi Mechanics

Most Mitsubishi Evo’s are “fast road” – it’s expected.  Many see some time on track days, while some are dedicated track warriors.  Whether you own a Mitsubishi Lancer Evolution, Eclipse, Diamante, Galant, Mirage, Montero, Outlander or other – we’re able to repair (or upgrade) your Mitsubishi vehicle.

Mitsubishi Repair


Mitsubishi Repair & Servicing

Whether you live in, or around, Kilbirnie, Glengarnock or Beith in North Ayrshire, JMA Motorsport is a great choice to repair or service your Mitsubishi.  In fact, we have customers from across the west coast of Scotland and as far as Aberdeen.

Besides the everyday stuff like alignments, tyres, brakes and annual servicing, we also do engine rebuilds, big horsepower swaps, dry sumps, swirl pots, you name it.  The guys here are Mitsubishi owners and really enjoy working on them.

All work guaranteed.  Proper name brand new parts only.

 


Mitsubishi Turbo Service and Upgrade

We all wish a turbo would last 100,000 miles, but typically they don’t.  We service turbochargers, including bearing/wheel replacements, housing swaps, whatever is required to get your Mitsubishi back on the road safely.

Performance-oriented owners will appreciate turbo upgrades, adding more power.  If you prefer quick spooling twin scrolls or big open high boost turbo’s, we can help you select the perfect combination of parts based on your horsepower goals, driving use (street or track) and budget.

 

 


Engine Rebuild, Swap or Repair for Mitsubishi

We do a lot of basic engine repair and service items for Mitsubishi vehicles.  The range from little stuff like oil changes, spark plugs, timing sets to the bigger ones, like head swaps, new headers and machine work.

High-performance projects include 4G63 and 4G64, and go anywhere from 400 horsepower to double that number.  Some prefer high-revving long rod motors that avoid rod flex at the bottom end, while others want peak torque for launches and acceleration.  We’ve done them all – let’s chat about goals for your Mitsubishi.

 


Induction Service & Upgrade for Mitsubishi

Many owners focus exclusively on the exhaust side of air flow around the engine.  However, some great gains can be had by improving the intake side.  Whether it’s manifold improvements or intercooler upgrades, more cold air means more power available.

Simple things can be done to improve air flow, like intake hoses made bigger, cone intake filters bigger and de-restricting everything to make sure your Mitsubishi can breathe freely.  Most of these upgrades are the most affordable cost per gain.

ECU


Mitsubishi ECU Mapping & Remapping 

Engine management is the brains of the auto, controlling more in a second than Apollo spacecraft did in hours.  Getting the right Mitsubishi ECU mapping done is absolutely critical to things like air fuel ratio’s, boost levels… the list goes on and on.

Depending on your goals, it could be that stock engine management can handle the power you want to run – in which case a simple remap can sort things out.  For those big power, big changes, we recommend modern ECU’s that give Launch Control, Anti-Lag, in-gear boost control, cruise control, multiple boost maps, and more.

Suspension Upgrades


Mitsubishi Suspension Alignment, Repair & Upgrading

Our North Ayrshire garage generally has several Mitsubishi (plus Subaru and a few others) on the go at any one time.  Alignments are done 6 days a week, both 2 wheel and 4 wheel.  We even do custom camber if you want a bit extra.

Need coilovers? New shocks, struts or springs? We do all that, plus drop links, adjustable toe/camber arms, lightweight wishbones – whatever you’re needing.

The best thing to do is start with a phone call and chat about your vehicle.
