hi how are you all.

my name is David, and i drive an 94 r33 skyline turbo

ive only had the car for a few months, so i havn't really got the chance to know it.

the other day i decided to drive my lazy self to melb (i live country east of melb), to the rajab dyno day. the result was 148.5 rwkw

the mods i have on the car are

fmic (it has no name)

it also has like a security door like mesh infront of it, something the previous owner put on

hks air filter

big jasma xhaust, im pretty sure its got a larger dump too

turbo smart boost controller (at 8, 12 psi) - it was at 12 on the run

turbo smart blow off valve

my car is running rich aswel, sometimes i hear a backfire on the down shifts.

to my surprise my friends r33 got 151.3 (with air filter, xhaust at 10psi)

i have been meaning to get my car tuned, but i live so far out.

any suggestions to what i should do?

any help would be much appreciated!!!

thanks a lot, fellas

Dave

hey SECUR1TY nices wheels.... oh and car too!

yea i can do the o2 sensor easy enough, and the piggy back is questionable.

are the safc's good? (assuming its all tuned right)

i have heard all over the place they are really good or very bad. i really cant afford a PowerFC too.

i also have another issue, its illegal for me to drive my car, i already have been done once by the boys in blue. however i was considered unlucky that day, because most r33 boys dont have too much trouble (im from vic by the way, on my P's)

so im even considering selling my car, so i want to prevent needing to put money into the car.

someone also suggested a fuel pump? yes , no?

anyways have a good day.

rgds, Dave

hey TracidTrax.

yea i know. ima country boy. i live 2 hours drive from anyone who knows what a car is, and possibly how to fix it.

i would get a tune sooner but its hard enough with travell and the fact i still have to go to skool.

how much do you think a tune up is going to cost me???

i know the dyno was poor, i will try to fix that figure!!!

cheers, Dave

my r33 has made 201.9kw with the following mods:

- no name dump, apexi front pipe, apexi cat back

- k&n panel filter

- avc-r @ 10psi

- safc II

- o2 sensor replaced

I got it tuned at UniGroup engineering. Heres a link to the dynograph. I reckon the figure is a bit high but it does show how the safc & proper tuning helped out :

thanks mate.

safc's are good if you go to the right place that will give you a safe tune, i.e. still run a LITTLE rich.

fuel pump won't be the problem, but you may want to upgrade for reliability reasons (stock pump can fail).

also if it's running rich, safe bet it's not the fuel pump. It's always good to run a little rich, as it's good insurance against burning valves..

did the workshop who dyno'd the car comment on a low reading? some dyno's can be fairly conservative. and if it's a no-name front mount, chances are it's a hybrid copy or something, which are very poor quality coolers.

if your car has those mods, it will probably be in need of a tune. and maybe get a workshop to plug in consult port which will tell if o2 sensor is broke, or injectors are maxing out, or afm isnt' working or whatever.

also, don't run more than 12psi on stock turbo!

hope this helps! i mean, how does the car feel on the road? does it feel like it should have more power? perhaps go to a couple of car dealerships and see what a stock r33 should feel like.

.

ive heard nothing but praise from the hybrid copy coolers. ive even got one sitting in my room waiting to be installed.

hey guys

sorry with late replys.

i havnt really had the time to think about whats gonna happen with my car.

but something will be needed to be done.

ive driven a range of skylines with the same mods, and none of them feel the same. weird.

i would really love to have a PFC installed, but i have no money! which is a bum.

i was thikning about getting a safc, so someone can tune it right. do yous think that would be a good idea?

i had it dyno'd on a dyno day, so they werent too interested on the result or what was going on, but i was pretty dissapointed

the intercooler on my car, looks dodgy. however its restricted a lot by the mesh that sitting in front of it, had trouble finding the time to take the front bar off. is it hard to take the front bar off?? also what would you use to clean an intercooler?

when i want to 'boot' my car i prefer to do it in 8 psi than 12. it jsut feels better. however still empty, and boost comes on around 3.5 ish rpm

i apologise for the bad attempt to explain all this.

better go keep the teacher happy now

thanks fellas.

ps. ruffels you car is a piece of ass

      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

      R34 Skyline climate control unit transistor

      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...

      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.
