Installing Hks Gtss Turbos On Gtr

Hello

I am installing a set of HKS GT-SS turbos onto my GTR and noticed that the banjo bolt for the oil line has a brass restrictor in it.

Does anybody know if I should use this or use the original banjo bolt which would flow heaps more oil?

The one that comes with the turbos has a oil hole that would only be about 1mm is size. The original banjo bolt is about 3-4mm in size. I would have thought that the more oil the better?

I can't read the instructions as they are in Japanese.

Any help appreciated.

Cheers.

You must run the oil restrictor supplied with the hks gt-ss turbos as ball bearing turbo do not need any where the oil a bush bearing turbo does plus the restrictor helps to drop oil pressure on the oil seals after the restrictor. For example i have had to restrict the garret ball bearing turbos back to a restrictor 0.8mm as the garret turbos do not like oil pressure over 60psi and a good gtr cold will do that idling.

      There is a LOT of stuff that can be done, it all depends on how much time and money you want to spend on doing in.  Not all ECUs will be able to do it, and the more control you need the more time and knowledge needs to be put into making it work.  If you're willing to spend the time and money and have the right hardware and skills involved there's a lot that can be done.

      I am impressed with all this level of adjustment. I didn't expect all this possibility

      Correct.  In the case of the 500kw dyno plot I showed you the car actually runs two boost control solenoids for boost control and a 5psi wastegate spring.  It allows me to control how much boost pressure is applied to both sides of the wastegate valve at any point and fairly accurately control boost target as a result. I've tuned it so that it's able to target anywhere from 5psi to 25psi depending on what's needed.  The target tables I've set up in that car are Gear vs RPM, so every gear has potential for a different boost (and torque) curve.   First and second gear have quite low boost targets, third gear actually has different target boost all the way through the rpm range as it's a stock RB25 gearbox - the boost targets have been chosen to maintain a peak of 600nm (what the owner has set as the maximum torque he's happy with putting through the stock 3rd gear) but it carries that to the rev limiter.   The boost curve to achieve that is something of a ramp up, then hold, then ramp up again and the power curve looks more like a flat line haha.
