Hi Guys,

I was hoping you could give me some advice regarding my 1993 Nissan Skyline R33 GTS-T.

The problem I am having is quite difficult to explain. I'll be driving along normally with the throttle open and then all of a sudden the revs will drop and the engine will cut out. It's like the throttle just cuts out. I can have my foot flat to the floor and the revs just drop and the engine cuts out.

But, if I then turn the ignition off and restart the car, it will continue on driving normally until of course, it happens again!

This happens every trip I make in the car without fail. It generally happens after I go over a large bump, or when I change gears. It has also ocurred twice when I have activated my windscreen washers. It also tends to happen more often when the car is cold, or has been driven hard for the first time in the course of the trip.

It also has a tendency to happen when the car is at idle-albeit less frequently.

The car also has a tendency to hit flat spots and hesitate at high revs (above 4000).

I have had the car dyno-tuned twice and the plugs replaced in an attempt to solve the problem. The car also has a new clutch. But, the problem began to occur before the clutch was replaced. Other mods on the car include a turbo-timer, short shift gearbox and sports exhaust.

It has been suggested to me that it could either be an airflow problem, or, a problem with the ignition regulator/modulator, but, the mechanic I have been taking the car to has so far been unable to fix the problem. Obviously I am not too happy with this and was also hoping you could recommend a reputable mechanic/workshop in Melbourne that specialises in or at least has a great deal of experience with R33 Skylines.

From my limited knowledge of cars, I feel it is probably an electrical fault or fuel injection problem, but, I really don't know. This problem is very frustrating and also very embarrassing when it happens in the middle of an intersection-not to mention dangerous.

Any advice you could offer me on this issue would be greatly appreciated.

I dont think it have to do with gearbox... if something wrong with some sensor I think it would stuff up ur car no matter what gearbox you have.... n lucky my '93 R33 auto has been driving beautifully so far... zero mechanical problems....

      S1 Autech 260RS Wiring Diagrams

      By ARB26 · Posted

      Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻
