It is easier to bolt on a supercharger than it is to get a turbo working.

See our article on performance exhausts for details of the issue around large bore exhausts and how to choose the right size for your engine.Īirflow through the head can be dramatically increased with some professional porting and polishing.Īdding forced induction will see big power gains but this is usually too expensive to be cost effective. Do not go with the biggest exhaust you can find this will slow up the exhaust flow rate - the best for power gains are usually between 2.5 to 3.2 inches. You need to derestrict the airflow into the engine as much as possible and the bottleneck on most engines is the air filter so fitting a cotton panel air filter will address this.

Lexus GS intake and exhaust modifications.īreathing mods are usually easily sorted and probably one of the easiest mods to do. Gas flowing the head and getting a 5 angle valve job will also make a dramatic difference to the power gains and torque band if done properly. Look to aftermarket parts suppliers for uprated injectors and fuel pumps and in some cases you'll find that your manufacturer offers uprated options as fitted to performance models. If your car is making more power then it will need more air and fuel so fuelling upgrades are important mods if you are serious about power.
One of the most significant with the best cost to power gain, engine mods you can do is to fit a fast road cam. Don't get misled by manufacturer claims of big peak power gains, they don't tell the whole story, it is the torque or power band you need to focus your attention on. Peak power is all well and good but if you want a truly driveable car it will need a wide power band and lots of low down torque. The 2JZ engine though is stunningly over engineered as fitted to the Supra we have seen power figures of 700-1000bhp on a standard block. In 2006 power levels dropped as the more economical 3.0 V6 3GR-FSE engine was introduced but by 2008 power figures were again on a steady climb. You can usually raise the power of most engines by around 20% before you need to think about strengthening the block. Even the relatively small 3.0 2JZ-GE engine puts out 225 bhp in standard form. When it comes to car tuning you always get a percentage gain so start off with the range of powerful engines Lexus have used you have a great basis to work from. It doesn't take a lot of money to make big changes to the performance and handling of your GS If you want to get a little more power out of the top end we need to choose our mods carefully. We shall now turn our focus to the GS engine. Adjustable shocks work best here allowing you to tailor the cars handling to suit your driving style.īear in mind that a track day suspension setup will be hard to live with on our roads with potholes and rough surfaces to contend with. To improve the handling you are generally looking at suspension and tire upgrades and larger drops are not always good, as it can impair the ride quality. Handling modifications are usually high on the agenda for the GS tuning projects. Then if you start modding it you can end up with something very special indeed.
If you do some serious weight reduction you will literally transform the standard car into something quite nippy and agile.
The GS is frequently overlooked as a performance car, probably because of the badge and fact it is a saloon but with the excellent range of engines on offer it is a really good candidate for a car tuning project.ĭue to it's size and equipment load there is a lot of weight in the GS which can hold it back.
