Hi guys, I have a 33 Skyline GTST that is producing 380Hp and and was pulled over last week by Traffic Police. I have a top mounted GT35/40 that i have been instructed needs a mod plate. Upon visiting the engineer, we discovered that law states "if the turbo/supercharger does not meet factory specifications it is classified as an engine modification, which requires the approval of fuel system, brakes, gear box, and diff. I do not doubt the the components are strong enough, but in order to get it plated properly i need some kind of paper work confirmation. Does any one know or have access to the Hp limits of these components, or know of a factory produced vehicle producing similar Hp and using the same components? I know Nissan produced the 400R but have been unable to obtain a definate answer as to weather GTST's and GTR's use any of the same running gear/brakes. If anyone can help it would be greatly appreciated. Thanx.

      Leak from Tokico BM50 Brake Master Cylinder

      By GTSBoy · Posted

      The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/

      Yeah, I guess its pretty easy to get to if this doesn't work. Just wait till next oil change and pull it out. I am going to have to do the oil pan gasket soon and thought I'd just replace it while I was there.  Thanks

      All that matters is you're safe and you were able to type that post. Hopefully heaps of parts you can recover for the next shell.
