Suggestion please for replacing hardlines with high quality ( assuming m12 x 1.5mm?...are all banjo bolt threads the same on Mitsubishi turbos for volvo?

  • A turbo specialist told me once that you don't need water cooling. Oil should be enough. You can eliminate all the cooling lines and hoses and all will be well
  • I have a custom 16g, run at 15 psi and higher. I don’t want to mess with what has been a very reliable and fast set up that keepsnice and cool under load, even if some say you can get by without water cooling, call it peace of mind when when I’m thrashing the 740 for long periods of time!
  • It's up to you. The turbo shop owner told me in detail, he supplies turbos (much larger than yours) pushing much higher levels of boost, generating tons more heat, with no water cooling and no problems whatsoever

  • @RichGT I have previously used the eBay braided line kits (available for approx $100) on a friends 15g swapped 740. He hasn't had any issues but if you had any concerns you could take them to somewhere like enzed or Pirtek and have new lines made.

  • This is a 12b housing, with a 16g...it’s old, but works well, not ready to risk it on a street car, water cooling is good. Thanks For the link Tim
  • So 12b exhaust housing with a 16g 4g63 turbo? Probably easiest to remove your existing lines and take to Pirtek or enzed to get them made up if you can live without the car for a couple of days
  • I have some flex lines that were for a turbo install done a while back and they were not used.
    I will dig them out and check the thread sizes, I recall there were two different thread sizes across the 740/940 turbo ranges.
  • That would be useful thanks
