Hi all.

Just gave my 93 R33 a run at full throttle from about 60 kmph and it started "popping"

93 R33 gts25t

Only mod is turbo back full exhaust .

Standard boost, no pod.

The popping sounds the same as when it changes gear under heavy acceleration. It started around 5-6000 rpm and lost all power while it was happening.

Could it be?

A, fuel cut.

B, Detonation.

C, Faulty wast gate / Std Bov

I would love some opinions and to hear from anyone who has had this issue and fixed it.

Thanks all.

Also it didnt happen anywhere near as much if I accelerated slowly to full throttle still did a couple of pops but held its power.

Yup you got it. Exactly the same.

Ill start working on the electrical side as soon as i have done the fuel pump.

I changed the filter and it helped a little.

Its going to go something like this,

Fuel Pump, injectors and the things that they include..

then ignition side coil pack, leads plugs.

Im not looking to make it a rocket ship it will just be nice to have it running at full capacity.. (foot to floor no issues)

Check your FPR, pull the vac line off it and have a sniff.. If it smells like fuel, then it's a faulty FPR.

I had the same problem as you, but my issue was contaminated fuel..

Could also be a faulty pump.

By the way, do you have a larger pump ? Say a 040 ? If so, they hate 1/4 tanks of fuel lol (well mine does anyway) and it surges on boost..

Firstly im going to get the std pump to 12 v so its running at full pressure and see if that makes a difference. After that ill fit the 040 as the DIY topic explains.

I take it "FPR" is Fuel Pump Return line?or something to that description?? The one that runs from the engine back to the tank past the filter??

  • 3 weeks later...

had similar problem after fitting 3" hi flow cat. changed plugs to iridium and reduced gap slightly 0.9 mm i think, smaller gap better when combustion pressures are higher as fuel harder to ignite. gave coil packs a good clean as there was carbon around them. ran fine then. drew

    • How much is it to re-uploster?  Well that's a "how longs a piece of string?" question !  And I answer thusly: "twice half its length! " . . . . . .  Seriously you'll have to chase multiple quotes for that one from different uphlostrerereres !  Ask around, in your area and on the forums, chase reviews and most of all see the finished product in person cause photoshop is a wonderful thing !
    • Hey everyone!!  I've noticed that whenever I do my oil changes, after putting 4L in, the oil level sits at the top mark in the dipstick. This is after letting the old oil drain for a very long time too! I've checked the oil level daily for the past few mornings. It happens every time and it's confusing because all the threads say that it should take about 4.7L (With some just adding the full 5L) My next thought is to figure out if the dipstick I have is correct so could someone please tell me the length of the RB25DET engine oil dipstick?  I've checked images of some of the genuine dipsticks, but none of them have the length in it. https://justjap.com/products/genuine-nissan-engine-oil-level-dipstick-fits-nissan-r34-skyline-c34-stagea-c35-laurel-y34-cedric-gloria-rb25de-t-neo?currency=AUD&srsltid=AfmBOortQXofgmiHVRKuIaiKuygL4k0Ewp68c3isGZk0vvKOJ7Yqf3iB However.... the engraving on the genuine ones say 05002 while mine says AA000. This makes me believe that maybe I have a wrong dipstick? I just want to confirm before I buy a new one. The car is a fresh import from Japan so I don't have details of the previous owner to ask him. Thanks in advance 🙏🏾 
    • Sport. I didn’t rebleed it cause I just removed the slave and left connected.    I will change line and slave and see how it goes.  
    • Oh and how is the rattle when foot is on the clutch ?
    • Did you get the sport or track ? From what the documentation says the uniclutch has a small amount of movement to disengage.  So your story of tricky pedal setup seems common.    Hopefully you got it bled up too, as the bite point moving around is usually either plates wearing in or air in the line.
