 Induction  
Induction modifications allow the engine to breathe more easily, a hi flow foam Air filter flows more air, so more fuel can be added to make more power and torque.  The easiest and the first modification you make.     450 - For Two and City Coupe and Cabrio 1998-2007
Lower restriction in the inlet side means that the turbo get up to speed (120,000rpm - 2000+ revolutions a second ! ) making gear changes feel quicker.     451 For Two Coupe and Cabrio 2007 onward 
Custom carbon/Alloy cold air induction kit, free flow direct cold air feed for maximum power, this best suits more modified cars and works well in conjunction with other modifications including, larger turbo, free flow sports cat exhaust and a suitable remap to ensure all the modifications work together.     452 - Roadster and Roadster Coupe

 Intercooler pipes
These were developed to maintain high boost pressures and allow better flow through the design of the cross section of the pipe.  We did see a small increase in power but nominal - when we tested the pipes but it was steady boost levels they were designed for.  The shape of the pipes change air flow more than a smaller constant diameter pipe - as these twist and turn through the cramped engine bay - optimum flow and  no deformation under boost or vacuum and not subject to heat as the thinner imitations were our design specifications.      
 
These are oversize Forge silicone 4 ply and allow more flow through the standard intercooler, these will really work better if used in conjunction with free flowing air filter and TIK Air line -the strong 4 ply construction does not collapse when the throttle shuts and is much stronger than its imitators ●  (Fitting time 1hr)   Forge Motorsport 450/452
 
These are oversize Forge silicone 4 ply and allow more flow, the kit comprises of the intercooler pipes (x2) and the Tik intake pipe, this is designed to work in conjunction with free flowing air filter ●  (Fitting time 2.5hrs) 451 TURBO (84ps)   Forge Motorsport 451 (84hp)

 Exhaust
The exhaust system functions ok for the standard level of performance, however freeing up the exhaust will allow the engine to perform better as it can expel the burnt gasses quicker, a good design would ensure the gas pulses help draw the following wave of exhaust gasses out too meaning the car should be able to back on boost promptly after each time the throttle had been shut (like when changing gear), a sports cat (around 200 cells) would allow emissions to be within legal limits.      
Janspeed Stealth exhaust is one of the best designs around and well made, a great sound and gives great power and torque, stainless steel stealth design - this proven exhaust outperforms all its competitors and gave +7% when tested back to back on a std Roadster ● (Fitting time 1hr)   Janspeed Motorsport 450/452

 ECU reprogramming.
Obd tuning program changes turbo boost pressure, fuel and timing setting optimising tuning for the engine.  Increase power up to +30% power and +35% torque increase ●.  Your MPG should not increase as long as you don’t use the extra power.  The cars leave the factory with fuelling set to comply with set tests and government figures.  Changing the mapping to suit vehicle characteristics on the road often improve the mpg • (Fitting time .5hr)   Smartcar Specialist Ltd 450/451/452
 
Ecu custom reprogramming with dyno power test custom made tuning program to suit your cars modifications, rolling road dynamometer run showing power ● Power up to +40% • (Fitting time 3hrs)   Smartcar Specialist Ltd 450/451/452/454

 Head tuning
Conventional tuning also works on the smart car- but cylinder head work is expensive as it is very time consuming and the rewards much smaller than some of the cheaper modifications.  We would recommend changing, camshaft and valve springs and Brabus valves with the cylinder head modifications.      
Brabus valve springs, allow higher rpm and reduce valve bounce Qty 6 ● (Nb recommend other head modifications at the same time )   Oem Brabus 450/452
 
 Camshaft
Brabus Camshaft allows increase in lift and duration of valve opening allowing more power to be made (nb recommend in conjunction with valve springs)  ● (Fitting time  3hrs)    Oem Brabus 450/452
 
 Ported and flowed cylinder head.
Ported and flowed to allow better quantity and quality of gas flow, standard cylinder heads are usually suboptimal due to design and manufacturing constraints, Burr and casting marks smoothed out to allow better flow and mix and maximise performance.      
Flowed Polished head BARE no valve, valve springs, followers, camshaft or followers included.  Exchange req £250 surcharge 5 hrs labour to clean and smooth the head, remove burrs and prepare head ready for refitting the timing components ●  (Fitting time 10hrs)   Smartcar Specialist Ltd 450/452

 Magnecor plug leads
The standard Spark plug leads work fine for standard engines, those running higher boost or modified will be subjected to higher temperatures and the spark need to be 100% to ensure power is not lost through failing/poor quality ignition conductors.  If you need to replace original conductors upgrade them at the same time.  Magnecor leads reduce Electro Magnetic Interference and reduce the chance of electrical miscommunication in today’s advanced vehicle management.        
Magnecor HT leads made from aerospace extreme heat-resistant silicone rubber.  Metallic Inductance Suppressed Conductor will suppress EMI indefinitely and maintain optimal spark for your engine ● (Fitting time 1hr)   Magnecor 450/452
 
 OBD multifunction Gauge

 Brakes
These works fine as standard in the Smart but changing to better quality discs and pads will allow you brake harder and more often and in shorter distance.      
 
 Brake pads
Performance Brake Pads Designed to give drivers a significant extra margin of safety, these pads have been extensively tested and designed so that they give almost racing-level brake performance. Thanks to Kevlar based asbestos free low metallic content friction material these pads work constantly well from cold up to 950C. Wear rates are similar to those of standard road going material with the advantage of low brake dust on alloy wheels ● (Fitting time 1-1.5hrs)     450/451/452
 
Brake discs are designed to stop the car, these are from higher quality base materials and include racing influenced drilling and grooves, these allow heat to be more effectively removed from the metal under hard braking and remove the brake dust created under braking      
A range of high performance discs for the Smart we recommend grooved or combination drilled and grooved, the main advantages are improved brake fade characteristics, in improved de-glazing and higher working temperatures ● (Fitting time 1.5hrs)     450/451/452
