ok so i finally finished installing my FMIC today and went for a lil test drive in it. Had the boost controller adjusted wayyy out so stock boost. Gave it a bit and i felt it jump back alot once i hit 4.5k rpm. It used to do this before i adjusted the boost up to 12 so i just assumed it was that and got out and adjusted it up (although it had done it more than before) so i cranked it to where 12 psi is, then accelerated in 1st to about 4500 rpm. Felt a bit better until i hit the 4500 rpm then a loud bang and a whizzing sound from my turbo. Then the car stalled. .. I started it once more and it idles but very roughly and the turbo whizzes very loudly, as soon as i put any strain on it it stalls, I can hear a rattling sound coming from my inlet manifold to. Is my turbo/engine rooted? If so what would have caused it? Could it be a problem caused by some kind of intercooler leak?

Edit... hose ^^

wait up, was a hose came off but was ver hard to see from the angle i was looking at lol. Um should my inlet manifold be rattling tho, the hose is on but im scared to start it as im scared it sucked up some crap into the manifold and its siting there

yeh was the hose, sorry if my sentences sucked, i tried to say nevermind it was a hose but came out all retarded. I think was just something to do with unburnt fuel or something causing the ticking in the inlet manifold. With hoses on its gone. Was woried :)

have got a problem still tho. I get what sounds like an annoying constant beeping as soon as boost kicks in. Its not the normal turbo spooling sound and doesnt incease in frequency much.. Is this because of the new cooler or something? Or is there likely to be a boost leak somewhere

found the problem, the underside of one of the silicon joints had a split in it :) Thought those things were good for a fair bit of pressure and stretching (didnt overtighten em) ive replaced it and will eventually replace them all. Its the justjap kit, all the welding is pretty mickey

      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.
