They both have lapped much faster cars than them by simply out driving.
Good luck |

my AWD IS350 Fsport 2015 got smoked by a 2018 Toyota Camry XSE he said has intake+exhaust. that's weird.

When I got my IS350 I made the choice between it, the Focus RS and a VW golf R. The R didn't have a sun roof so it was out. The Focus RS was marked up 10k above sticker and it had no reliability record. So IS350 it was. If you want a seriously fast car trade to IS in and get a Corvette or M3 or Focus RS. The IS350 is not the fastest car on the block. It looks damn nice and will outlast a sti.

Get our suspension package and Supercharger for your IS300/350, you will be right up there with a tuned Focus RS. As for reliability, I'd much rather tune a 3.5L 6-cylinder engine to 360whp vs. a 2.3L 4-cylinder.... its a no brainer. I was pulling with a Focus RS the other day and it wasn't even close. Our stage 1 IS350 SC is also equivalent to an Audi S4 with APR Stage 1 tune (don't ask me how I know). The Focus RS main advantage is that it has a suspension and tire package that is optimized for performance. It comes with Michelin Pilot Cup 2 tires STOCK (which will last about 6000miles:)! The IS platform is actually very good. Lets put aside the interior which is leagues ahead of the focus/subaru/evo econobox interior... the Lexus has an inherently better suspension design -- double wishbones up front, versus struts on the other cars.

I have to respectfully disagree. I think the Focus RS is already showing its true colors, as there are many reports of stock cars with various engine and differential related issues.

Rafi One issue...like any direct inject motor, you will have excessive carbon build up that will require walnut blasting approximately every 30K. It's a simple task to complete at home and requires about three hours of your time. |

I'm with you on this one Rafi. After owning and stage-2 tuning two STI's, the Lexus G series motor is bombproof! The RS is an expensive piece of garbage riddled with issues. The G series motor has been around for quite sometime and has a great track record (pun not intended). There's a reason it's still in Toyota's lineup. A simple RR Tune will safely get you above a stock STI. Adding the headers and a high flow exhaust put no extra strain on the motor and you get a huge bump in torque and HP.

Why would a G motor need this if its also port injected?

It's direct inject and port injected. You still get carbon buildup, just not as bad. I'll do a video of the cleaning process once my engine reaches the 30K mark.
I found this thread that might help you. https://www.clublexus.com/forums/is-...s-problem.html It would be interesting to see your engine when you clean it. We have opened up several ISF engines, and there is a big difference between an engine that runs our Air/Oil Separator (AOS) vs without. With a proper AOS, it is super clean. Rafi |

Rafi Are you guys going to make an AOS kit for the IS? or can I purchase the ISF one? |
