  1. New spark plugs

    Because you cant get the DFE type in the cooler heat range
  2. Local Supercharger Expert - ISF

    The Bullet HTV1900 is a Harrop. I know because I had this exact s/c on my V8 Soarer... It is definitely a far better s/c than the centrifugal from RR Racing. shouldnt have to lose port injection because the injector bosses would be integrated into the s/c lower manifold if I was to go this far I’d not be worrying about intercooling and instead would convert to E85 as not only would you maximise gains but E85 runs cooler and gives additional headroom against pinging
  3. New Front Pads & Rotors

    17x10s with R-comps on the rear Obviously look different to the stock 19s on the front (17s arent doable on the front anyway) but they give far more and cheaper options for tyres for track days
  4. New Front Pads & Rotors

    PMu HC+ which I think are equivalent to HC800 are great pads capable of track days. Anything less than those in the PMu range aren’t really up to track work, I have a set of B-Specs and while the rears were ok, the fronts were getting too hot after 2 or 3 laps. Given that in my experience the HCs work from cold and have good bite, I should have just bought a set of those and not had to worry about changing pads if I do a track day.....
  5. lexus isf rev drops too low to 500rpm

    This is standard for the ISF it seems, it is not a fault. I suspect it may be for fuel economy/emissions reasons, to set the idle rpm as low as possible. I agree, in reality it is too low and a bit annoying but you can overcome it by turning on any source of electrical drain such as headlights/sidelights, window demister, A/C, etc... or put it in Neutral :)
  6. Is-F 2011 Poor Audio Quality

    The AUX input is no different to any other source except it is analog - it is still processed the same way, still goes through the head unit EQ and sound processor. The only difference is unlike the digital inputs you have the opportunity to pump a strong signal into it to compensate somewhat for the low gain, which may or may not work... I have run various sources through both the USB and analog inputs and they all suffer from the low gain of the stock system regardless. The difference in audio quality is barely worth worrying about.
  7. What oil does lexus use in the ISF

    My invoices from Lexus Perth say they use Mobil 5w 30...
  8. Supercharged ISF

    $8k USD for a messy inefficient centrifugal s/c install running only 3 pounds boost? Yeah no thanks. ill give them the benefit of the doubt and assume it's still early days but when s/c kits for the likes of the Toyota 86 (which runs higher static CR than this engine does) are superior twin screw blowers pushing 3x the boost for the same price, i think there's considerably more development to be done. [edit] For a more relevant comparison, the new Mustang has barely been released in AU and already there is a twin turbo kit in development (which is specific to RHD cars so its not just a US copy) which will be running 10-15psi (98/E85 fuel). Estimates of 450-600rwkw. Similar spec engine to the IS F - 5L V8, 11:1 CR
  9. ISF ECU tune , thought ?

    Fair enough, obviously the price/exchange rate is a lot worse since I got mine then!
  10. Looking to buy an ISF

    Your car is actually a MY2013, the changeover date was August 2012 :) MY2012 cars (ie, built from Aug.2011 - July 2012) do not have the HDD nav or BT streaming
  11. Looking to buy an ISF

    Mine doesnt, and it is a MY2012....
  12. Looking to buy an ISF

    2012 cars dont have BT streaming!
  13. ISF ECU tune , thought ?

    Considering the PPEs can be had through Chatswood for around $1600 delivered thats a ridiculous price for labour.
  14. New Front Pads & Rotors

    No need unless they are damaged/missing. only consumables are rotors and pads.
  15. New Front Pads & Rotors

    I got a complete set of front and rear OEM-spec crossdrilled rotors from GSL Rallysport for $380 delivered Put a set of Project Mu B Spec pads in and the brakes are better than factory plus far less dust, win-win :)
