Hey i have R33 series 2, auto when i put overdrive on and keep a steady speed over 70kph the revs drop by a hundred or 2 and then goes back up to normal. This was happening every few minutes but is now happening every 10 seconds? Mates have said maybe trans service or do timing kit. I think theres just something wrong with the overdrive, because the car runs fine with it off. If i take the overdrive off theres no change with revs. I have tried with and without air con and problem is still there. Does anyone know what the problem is?

might be worth checking the level of the fluid in the transmission. it may be getting a bit low.

^+1 as 9/10 auto trans problems are fluid related in my experience.

If not, try checking your coolant temp sensor readings for fluctuations as this will make the car drop in and out of over-drive intermittently.

      Forced Performance Hta Turbos

      Dredgggggeeee time; I have recently finally started driving the car. It sat for so long that the fuel tank gave birth to rust sludge and blocked my lift pump sock and one of my walbro 460's and left grime, rust chunks and muck all through the surge tank and system. I decided to commit and pull the trigger on an oem r32 gtr fuel tank and Frenchys twin 460 / sender / surge tank hanger combo and all new larger lines and fittings etc, also boost doc heater hose kit / new heater core and a heap of other bits and shits like wideband sensor installed in the dump and Syltech iacv + lines and all wired and added to current tune. now having lightly driven it a couple times without issue, I can happily report on the hta3076 in its current tune. still no boost control switched on, 20psi gate springs, car makes 22psi at 3200rpm in 6th gear with 30-50% TPS from cruise at 100kmh. Going by the old graph, this means it should be making 300-325whp at the same numbers above. Very very responsive setup under true road driving loads. all that's left for the build is body loom + PDM, finish the remote aircon setup, install carbon fibre parts and go for full tune and 30psi. the 315 rear tyres are now performing like they're 195's, wheel spin in any gear at almost any rpm, whereas my previous setup hooked up in 3rd no issue, albeit Nt01's back then / RB25 5spd vs (new) old date r888r's Z34 6spd now, + obviously all the support upgrades I listed in the quoted post above. car sits at 1-3psi on cruise at 100kmh, expectations totally exceeded and I'm beyond stoked with all this so far.

      I've also been eyeing their rear axles for my car. I purchased seat mounts from them about 7 years ago and they were hot garbage so I've been a little wary about purchasing them. With that being said, please buy them and get back to us haha.

      Being a manual, we very quickly ordered new R34 gearbox (From Nissan) and remaining parts from Kudos motorsports. Would highly recommend the team there. Ultra helpful and quick to share advice and upgrades. We are in the middle of taking the Auto out (Genuine 94,000/kms) and putting the Manual in this weekend. Part 2 of the build will include likely a Plazaman Intercooler and Plenium, Hks Exhaust with Tomei Dump (ordered).
