The first-generation Lexus IS is in a position to transform into a lightweight sedan powered by a 2JZ powertrain. If you’re not sure where to start, YouTube’s MartiniWorks has a list of recommended modifications to tastefully upgrade the luxury sedan.
While installing a 2JZ-GTE engine in the engine bay proves to be the ideal solution for increasing power, MartiniWorks recommends keeping the 2JZ-GE unturbocharged. Instead of opting for an engine change, the suggestion is to install a small turbo and remap the ECU. A 300-horsepower build would do wonders, which a GReddy Supreme SP exhaust formula could simply elevate.
The Lexus IS, sold as the Toyota Altezza in Japan, was designed to be marketed in the U. S. market with two transmission options: a five-speed manual or a five-speed automatic transmission. Of course, as a car enthusiast, the suggestion is to go through the manual. This setup and the rear-wheel-drive setup would make the sedan a fun car.
To improve its functionality on the track, MartiniWorks recommended installing BR Series threaded shocks, which would cost you around $1,200. These can be simply combined with a stabilizer bar, but it’s not really necessary. However, you need to make sure that your rings are in top condition.
In terms of looks, a set of 18-inch wheels with 215/40 or 223/35 tires would be a smart choice for the car. Specifically, five or six-spoke wheels from brands such as Enkei and Konig. You may need to stay away from SSR or OEM wheels, as they can also get in the way of wheel arches that are “too thin. “
As for the finishes, MartiniWorks recommends rearranging the brake lines, rotors, and headlights. The most productive thing is to leave the taillights alone, as they have the signature of this sports sedan rival to the BMW 3 Series.
