Is the IS F fast?
With 416 horsepower, the F in IS F could stand for fast—or for freakin’ fast—but you won’t be thinking about silly things like words when you’re the pilot of this rocket. After the test model was delivered to my office on Oak Lawn Avenue, I thought I would take it out for a quick spin.
What kind of engine does a Lexus IS-F have?
When developing the IS-F, Lexus gave their 5.0L V8 to Yamaha for a high performance overhaul. With high-flow cylinder heads, titanium intake valves, and an 11.8:1 compression ratio, Yamaha got the engine to 416bhp @ 6600 RPM and 373ft/lbs of torque at 5200 RPM.
What kind of engine does the 2013 Lexus IS250 have?
All 2013 Lexus IS250 models come equipped with a 2.5-liter, V-6 engine that makes 204 horsepower and 185 lb-ft of torque, which is enough power for pleasant acceleration and adequate highway cruising and passing, but is nowhere near sporty.
How does tuning work on a Lexus IS-F?
Before the tuning was available, owners were able to get by because the ECU will automatically retune itself in a basic way, adjusting to changes from basic modifications. If you open up the airflow coming in and the exhaust flow going out, that will allow the ECU to inject more fuel and make more horsepower.
How manybhp does a Lexus ISF make?
As for headers and exhaust, I’d recommend doing them both at the same time because if you’re going to do one, you might as well just do both and really get your money’s worth. With both the intake and the full exhaust system freed up to flow better, the Lexus ISF will make around 500bhp, give or take, depending on altitude and fuel quality.

Do you need a turbo for a Lexus IS-F?
Obviously the next logical step to the horsepower heavens is a turbo or supercharger kit, but they’re pretty damn expensive, often hard to come by or even custom jobs. You will also need to ditch the stock ECU at this point for a standalone unit.
What was the problem with the Lexus IS-F?
The problem was that the untuned engine was subject to significant power loss in higher temperatures. The IS-F’s newfound tuning solutions give the car more robust gains in various temperatures and a much smoother power curve.
