hey boys need abit of help my r32 gtr (running 12pound boost pretty stock with pods and an exhaust) when it hits hgiher boost and higher lvl of rpm as in about 4500rpm the revs start to break up and the car has no power. only started yesterday morning and has been doin it ever since. people ive spoken too reckon it could be an electrical problem with the air flow meters??

any advice/oppinions are appreciated :)

Gday mate,

Common problem that is usually coil packs or even the ignition amplifier, especially if they are still the original stock R32 GTR items. Mine had the exact same problem as did a mates.

I've even had an AFM problem however that went into a limp mode and limited the revs to around 2800rpm.

Hope this helps mate

If it is just one coilpack then you would be better to replace the whole set as they are all the same age and if one goes then there would be a high likelihood that the others would go too. It is difficult to isolate coilpacks because disconnecting individual coils may show no difference over 4500rpm but it will create a miss in the whole rev range, just confusing the whole situation, lol.

Your best bet would be to find someone else with a GTR and to do some part swapping to isolate the various ignition system components.

thanks mate i just took it for a drive and noticed that it doesnt do it when the clutch is engaged or it is out of gear??

yeah that would be right as the engine is under no load whilst out of gear, over 4500rpm and the the engine is under a decent amount of load

      Yeah, plenty of air flow, there is a dedicated path that feeds the air in to the OEM intake tube behind the bumper As for a "tangible effect", maybe, but getting the pod/intake air out of the hot engine bay is worth it psychologically to me, even if it gives no performance difference, so the tangible effect in my Lizard brain saysss yessss  In the end, to me a tangible effect isn't always about performance, sometimes it a sound or a look, or even a...... feeling  Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga Ooga-Chaka Ooga-Ooga

      yeah first and reverse is where you will find clutch release issues (whether hydraulic or mechanical) because the difference in revs required is the highest there; particularly changing down from 2nd to 1st when still moving. To be clearer though, it is possible that the clutch release bearing is the wrong height. This is less likely than a hydraulic issue but it is not unheard of when you are mixing and matching

      Replacing turbo water line - any recommendations or advice?

      By jtha7 · Posted

      Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!

      From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
