One of the longest turbo installs in the world and still no figures, would have been cheaper and easier to put the RR Racing supercharger on. The turbo lag will be horrible.
As we are not tuning the car that side of things are out of our control. There was an attempt to tune it and it had some issues and then the owner pulled it apart to change turbo. Its back running again but unfortunately we don't have dynos or anything more to show The lag isn't actually that much
All first turbos that where tried were done prior to ecu being cracked open. Now that ecu can be tuned turbo can be done just like Supercharger they are both forced induction. Main difference between two is that turbo setup is more complicated to build and install and harder to manage but up side is potential to make more hp. Not only has engine ecu is now tunable but transmission is now capable of tuning as well. One company has already done it and that particular ISF is in trials. RR racing is looking to develop their owned transmission tune as well. One of the big advantages to transmission tune is that it allows torque converter to stay locked all the way up to increase Redline of 7200 RPM. I wish them luck its nice to have option. I think S/C on 5.0 ISF motor works well. I would love to see Roots stlye S/C on ISF the low end torque and midrange would be crazy.
Short answer - no really. Turbos are quite abrupt in their power delivery, especially one this size. A turbo will "usually" run more boost and generate higher IAT's than a centrifugal supercharger. Superchargers are almost always more reliable. The trade off being efficiency and peak power.
The is350 has more engine bay space but theres nothing easy about any of this. Its all custom fabrication with a low mount turbo and no real preventative way to stop water getting in the intake for sure
No one in the world would trade and F for a g37 are you crazy you need too know what your dealing with this is a classic Japanese muscle and only so many were made
