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.

Gearbox strength should not be an issue, and even if it was the GTS-T gearbox is as strong as the GTR one. Differential likewise.

The only thing you may need to look at would be the brakes, which would probably require an upgrade to GTR specs or so. Depending on your power levels, there isn't obviously going to be any factory 400hp or so (?) car to base anything on.

You may just need to visit a few more engineers to get their opinion.

      Give the fluid a really good flush, then go do the same track again. Report back too please

      Need AC Compressor for R32

      By joshuaho96 · Posted

      I think most of the benefit there is really from the battery as well, having 1 kWh or so means you don't need the engine running at idle to run the AC, when the battery is depleted you can run much higher idle to charge the battery at a lower bsfc point and then shut it back down, you can regen on braking to recover some of that power too. I can't imagine the benefit from only running the compressor as much as needed is huge if you're mostly only running the AC on hot sunny days where it really needs to work hard to keep interior cabin temp under ambient.

      Yeah, unless you're doing it by the book, your data is probably not useful. Boiling point drops rapidly with only just a little water in it.

      How hard are you tracking it? I have 378 in front and 355 in the back with decent pads and my brakes were spongy after a decent session with lots of braking. It was a short track though but got up to around 190-200 max. be keen to hear. Mind you, I havent flushed my fluid so thats probably part of reason.

      Rb head oil drain dimensions

      By Papichulo96 · Posted

      Awesome thanks for the reply Man! I already plugged up the back just cause I can’t take a chance on it leaking on me again haha. But i will fab a catch can with 2x for the cam covers and a lower one for the sump vent.    Now as this will drain back as well , Is there any concern I should have of the oil being drained back. I don’t run e85 or anything .   2nd question is, from the picture does it seem that my sump fitting is above oil level? Silly question but I rather have someone’s experienced opinion lol
