There's a reason you see so many Miatas at track days and autocross events. We won't know who you are personally or be able to track you after your visit to our site. If you go for a larger compressor but the standard size exhaust housing, however, this can give more power but the small exhaust housing can be restrictive at high boost. So if you are serious about finding the best tuning mods for your car. Exhausts If you fit a huge bore exhaust to a non-turbo engine it can often lose you low down power and torque, but fit one on a turbo car, and it really is the bigger the better! There are a lot of considerations to make when adding a turbo to a NASP engine. If you are forcing more air into an engine you areincreasing its volumetric efficiency (the efficiency of the engine at drawing in air). Forced induction is where highly compressed air is fed into the engine. The evaporating water absorbs loads of the heat from the pressurised air, bringing the temperature down to a safe level. Use of this site: Please treat the information on this site as purely speculative. There is a lot of debate in our forums but we have compiled a list of the best tuning mods for this article based on feedback from our members. . Turbos are expensive but will add the most power for your money. An advantage of a screamer is that less gas will be going down your main exhaust system. Please drive sensibly we do not endorse speeding or racing on the public highway or driving recklessly or in a manner than could endanger life or property. The best turbos to add to a non turbo NASP engine are small units with low boost levels unless you are prepared to invest heavily in engine mods. We are going to ignore the most popular mods, as these often only turn out to be aesthetic upgrades rather than performance upgrades. It might seem a little strange to see a mid-range BMW on this list, but in reality, the turbocharged N54 straight-six under the hood of the 335i can handle massive amounts of power without a crazy amount of work. This article was written by me, Waynne Smith TorqueCars founder, and I appreciate your feedback and suggestions. When the heat and pressure inside the combustion chamber is so great that the fuel/air mix ignites before the spark plug fires, its called detonation. High octane fuel is the friend of turbo cars, as its much more resistant to det (detonation), enabling cars to run higher boost safely. Pre-ignition / detonation Pinking or det is the main killer for modified turbo engines, and is what blows headgaskets and destroys pistons.

The hotter air is, the less dense it is, so the lower the proportion of oxygen content, which in turn means less power.

Just turning up the boost with no appropriate adjustments to fuelling is bound to end in disaster, so make sure it is sorted. On most aftermarket turbo applications it is unlikely that the cars existing fuel delivery system will be able to deliver sufficient fuel so you will need to uprate the fuel pressure with a new pump and fuel pressure regulator, the injectors will also need uprating. Take an extreme example of a turbo charged 1.6 engine in early Formula 1 motorsport that produces almost 1500 bhp. Some replacement turbos could be the same size as your current one, but are simply stronger and capable of running more boost pressure without failing. With modern ECU's and engine management the efficiency of the engine and drivetrain is always improving as emissions standards get ever tighter. document.getElementById("comment").setAttribute( "id", "af7e2908516c6ba2a27650289b4706fc" );document.getElementById("bc9bd3f3e4").setAttribute( "id", "comment" ); Join our forum today and benefit from over 300,000 posts on tuning As important as position though, is it being unrestrictive.
