hey,

car is now going. Changing gears is some what tempromental. I change gears, and get crunching. Could this be due to gearbox not having right oil in it.

i have used some castrol 75 W 90 W gearbox oil.

am a bit worried it could be stuffed, with a synchrose, but the gearstick does flow into each gear pretty easily.

any thoughts. or recommendations....

how much oil did you put in? because i was having the same problem....but mostly going from 1st-2nd...

its really important to only fill till it spills out from the filler on a FLAT surface...cause first time i changed mine i didnt lower it back down to get rid of excess...

did that last weekend and i had about 400ml too much and now it shifts heaps better....

im kinda having a little of the same problem too.. when i first take my car out in the morning when i go from 1st to 2nd, 2nd feels really tight but after about about 5 minutes of driving it loosens up and goes normal. what up with that huh. also sumtimes when your driving kinda normal and in 3rd changing into 4th it wants to jump out of 3rd while your changing..kinda like it cant wait to get in 4th.. what do you stooj`s reckon

Its got to do with the viscosity rate of the oil.When the oil is cold,its thicker which makes it hard to change gear but when it warms up,it thins out and gear change is easier.I know its expensive but try fully synthetic g/box oil.problems will be fixed.

I just did the gearbox oil on my R32.

I bought REDLINE lightweight Shockproof.

It's excellent.. I can't recommend it enough.

my second gear use to crunch but now it doesn't do it at all.

anyway, that stuff sells for $25 per litre.

I just bought the 3.78L bottle, $100.

The R32 GTST gear box takes 2.8L for those who are interested.

I know $100 sounds expensive at first, but when you consider that you change your oil every 5000kms and if you are using like MOBIL 1 synthetic, it costs you at least $50 each time.

how often do you change the gearbox oil?

It's a very good investment...

I found my one from Croydon Racing Development (or whatever they are called now...in silverwater, sydney)

i bleed the clutch lines again. and the brass button feels a lot better....

But then the clutch pedal welds snapped. So the metal casing which bolts up to the car makes the pedal stick behind the brake pedal.

was lucky i was only 2 minutes from home when it happened.

i am gonna do the gearbox oil again...

      S1 rb25/s14 starting problem

      By Duncan · Posted

      Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.
