Hello all,

I recently got myself an N/A 1999 Nissan Skyline r34 25GT 4-DOOR sedan Tiptronic transmission, completely stock. I'm fully new to skylines and know not much about cars lol, so wonderin if any of you's could help me out:

Question 1: Is it normal for the car to jerk when you change the transmission from say Reverse to Drive (like the car gets a push, feels like a jerk)

Question 2: My fuel guage is incredibly innacurate (after I fill up, it shows as "full" even after like 70kms!)

Question 3: Is it ok to use normal ULP, if not... what exactly would happen?

Hope someone can help!

P.S. i've attached some pix of it if you're interested

nice, got a clean car there.

Q1/ ensure the car is completely stationary when you change gears; i.e. reverse out of driveway, ensure car is completely stationary, foot solidly on the brakes, shift slowly but smoothly into drive, release the brake and onto the accelerator. give that a go and let us know.

Q2/ 70kms is fine, normally it's accounting for the fuel in the pipe from the filler cap to the tank.

Q3/ i wouldn't recommend it as i believe the lowest octane rating in japan is 98ron. you will get increase of knock and possibly pinging (more prevalent on turbo cars) on an n/a you might get away with it. to give you an idea i had to fill my car with unleaded once, because that's all the petrol station had - and my safc2 read knocks up to 46, as soon as i found a servo with premium i put it in straight away and once empty, i filled it up again with premium and i get knocks in and around 15-25'ish, this is of course due to the fact that my car is tuned for premium unleaded fuel. if you wanted a car to run cheaply on fuel, you wouldn't have gotten a skyline in the first place.

hope that helps

lol thanks to all, and EUG about your solution to question 1, i actually do always change it while fully stationary and in fact it gives less jerk when the car is still slightly in motion. it sorta feels as if the car is readying itself to pwn some ass lol. and lol ok 98ron it is, what's with hillzy telling me differently!

      R32 update from 1990's spec.

      So for the wide band is a Bosch 4.9 correct for the Link G4+ along with a Can bus? Just get the Link gear or is generic ok too? Eg here: LINK LINK DIGITAL WIDEBAND CAN MODULE WITH BOSCH 4.9 SENSOR : KYP Performance House

      RB26DETT Sketchy boost mod?

      Bit difficult to follow. Have a look below and see what the standard R32 layout was like. Note there was a restrictor in place immediately before "turbocharged pressure control solenoid" that, if removed, magically got you 1 bar boost.

      I might be way off the mark here.. there must be a T junction under the manifold. That takes manifold pressure through a check valve prior to the T, one side splits out to this bleed off orifice, the other straight to the wastegate actuators.

      RB26DETT Sketchy boost mod?

      By ARB26 · Posted

      Carrying out some engine due diligence before my first drive in a 260RS that has been in storage for 10+ years, and found two lines that are susposed to be plumbed into the boost control solenoid. One of the lines (the wastegate boost supply line) to actuate the gates, had a bolt in one end blocking it. The other line (main boost signal line) from the very rear of the intake manifold (RB26DETT) and runs up to the boost controller had this pill in the end of it as seen in photos. Other than the obvious (T28 Ceramic turbos might well be cooked)  Can anyone shed any light on if there is any validity at all with this mod, bleeding a constant fixed rate of manifold boost pressure off through this 3mm hole?  Is it deliberate?  Was this a 90s Jap mod done to RB26's? Or has someone just fitted this without any idea of what happens to ceramic T28s if they are not gate controlled?
