hey i have a strange hesitation when accelerating. it accelerates to about 3800/4000rpm then really struggles (big lack of power) then once it gets to 5000/5200rpm it kicks hard again at full boost. any ideas?? please!

only mods are turbo back exhaust, k and n pod and turbo smart bov. no boost controllers.

Lets do this by trail and error. Yes Just make sure they are gapped to .8mm. 1.1mm is great for modded cars but you have much the same as I had.

Yes try cleaning the air-flow meter with brake cleaner. Take it easy on the trigger,,,just a mist spray. Some say they are self cleaning but that is just not true.

Next get rid of that stupid bov and go back to the factory one. On standard boost the factory one is more than capable.

It can't be coils because they only ever fail at higher rpm.

If all this doesn't fix it you need to start talking to a Mechanic.

Neil, I thought 1.1 was good for standard cars but 0.8 for modded? :confused: Also, the factory bov is more than capable, but so is the turbo smart one. So why bother wasting time and effort pulling something off that already works properly?

Sir33-I had a similar issue but my car struggled from 4000rpm onwards, I changed spark plugs and gapped them to .8 but it didn't fix my problem.I then took it to a workshop and they fixed it.The guy on the counter said that it was my spark plugs and that the mechanic re-gapped them.I tried to find out at what gap he set them but the mechanic wasn't around.Car is going unreal now.

Jimx sorry,,,Yes I got it around the wrong way. 1.1 for stock and .8 for the big boost boys. The reason I want him to go back to the factory bov is to see what happens. Maybe the Turbo-smart one he's using is faulty, Wouldn't be the 1st time a product straight out of the box was stuffed.

boj, where u get this done?

i have the same prob.. same mods but hks ssqv.

i was told best to get a  aftermarket ecu like power fc or safc and it'll fix the prob.

Hooligan-I went and saw the guys at JustJap at Kirrawee.Worth getting it checked out before you splurge some money on something that might not fix your problem.

      R34 Skyline climate control unit transistor

      By sinn3r · Posted

      perhaps i should have mentioned, I plugged the unit in before i handed over to the electronics repair shop to see what damaged had been caused and the unit worked (ac controls, rear demister etc) bar the lights behind the lcd. i would assume that the diode was only to control lighting and didnt harm anything else i got the unit back from the electronics repair shop and all is well (to a point). The lights are back on and ac controls are working. im still paranoid as i beleive the repairer just put in any zener diode he could find and admitted asking chatgpt if its compatible   i do however have another issue... sometimes when i turn the ignition on, the climate control unit now goes through a diagnostics procedure which normally occurs when you disconnect and reconnect but this may be due to the below   to top everything off, and feel free to shoot me as im just about to do it myself anyway, while i was checking the newly repaired board by plugging in the climate control unit bare without the housing, i believe i may have shorted it on the headunit surround. Climate control unit still works but now the keyless entry doesnt work along with the dome light not turning on when you open the door. to add to this tricky situation, when you start the car and remove the key ( i have a turbo timer so car remains on) the keyless entry works. the dome light also works when you switch to the on position. fuses were checked and all ok ive deduced that the short somehow has messed with the smart entry control module as that is what controls the keyless entry and dome light on door opening   you guys wouldnt happen to have any experience with that topic lmao... im only laughing as its all i can do right now my self diagnosed adhd always gets me in a situation as i have no patience and want to get everything done in shortest amount of time as possible often ignoring crucial steps such as disconnecting battery when stuffing around with electronics or even placing a simple rag over the metallic headunit surround when placing a live pcb board on top of it   FML

      Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

      I think Fitmit had some, have a look on there (theyre Australian as well)

      Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.
