hey all, just wondering what your predictions are for my new donk. should be rolling out hopefully tomorrow or monday at worst. oh the suspense after sitting in the driveway for 4 months!

R33 GTS25t

-pod

-3in exhaust (possibly dump as well, output seems pretty good)

177rwkw

now with:

-replacement engine

-kkr430 turbo

-fmic

-forward facing plenum

-440cc injectors

-fuel pump

-bov

im thinking ill go for 13-14 psi boost. and am hoping for at least 200rwkw, optimistically 210. what do you think?

also, 1/4 mile on 255 bridgestones? im thinking 13.3? am i having a wank dreaming of 13.0?

haha appreciate any input. bear in mind this is the 2nd engine ive had to replace in 9 months so funds for bigger mods have been hard to come by.

i am looking forward to pulling apart my wrecked motor, some may remember it getting a compression test of 0psi in one of the cylinders. so i might post some pics when i get stuck into that. also, im hoping the head is fine so there might be a few bits for sale soon.

thanks guys!

i have read that on an r33 the KKR480 was good for 270RWKW at 18psi, i 'd say the 200-210 make your thinking would be about right.. if not slightly higher..

are you running some sort of piggy back ECU or full aftermarket??

Well a bonnet down 177rwkw is a high 12 over the 1/4 if you have something remotely wide tyre wise on the rear and you have by a long way. I'd say if that pod filter has no cold air partition and feed the 177 is more like 150 realistically on the road.

You have aftermarket engine management right?

If drag racing is something you want to have a go at then things like some pineapples for the rear diff cradle wouldn't hurt and hopefully you have an upgraded clutch in there too.

A 12 should be so easy it isn't funny if you are making a genuine 210rwkw bonnet down.

:D

thats alright! but mines a 430, not a 480 :D

well, no im strapped for cash, so im remapping the stocko ecu. which is not ideal i realise, but i will get a pfc by my 21st in july hopefully.

wha? the pod doesnt have a box or anything, though if you think its wasting that much power i might have to make something up! surely its not worth 25kw though? :D

yeh as i said above, remapping stocko ecu because i havent got the cash atm. but i will go pfc for sure.

im not really that into the drags, but i would like to know my times just so i can ram them up my commo-loving mates. not sure how long the clutch will last though :D but my tyres seem to develop a lot of traction certainly compared to the ones i had previously (theyd bloody want to for $425 each)

12s!! sweet as!

Yep it's worth a fair whack alright. The engine bay air is often 70+deg C around town on a hot day it's hotter again, it's not a good thing really.

If you are getting a full remap (fuel and ignition) then thats fine although I thought the R33 remaps were as pricey as a powerFC?

It's 12's when you actually do it on the strip. Not a lot of point talking about how fast your car is going to be but, rather just go and see. :D

wow. thats some hot air. so what do you have to do? shield the pod from the engine bay, with plastic or something? heat wrap? or redirect it somehow so its drawing cooler air?

i have been told they charge hourly rate to do ecu's, which should equate to maybe $3-400 at worst. i dont see how it could cost more than that! it would be a waste of time if it did.

know that, that why i said around the 200 -210rwkw mark, i didn't think there was anyone re-mapping the r33 ECU? and charging by the hour sounds more like dyno time then re-mapping the ECU?

may be an SAFC / SAFC 2 could be a good cheaper option than the re-map? you should be able to get a good second hand one for $200-250 then at a good tuner maybe and hours tune.. $100-150... you can also re-sale the safc once you get the PFC hehehe..

Good luck finding a pfc.................

There impossible to fine

well brand new i mean...............And you dont wanna get them second hand....

Btw with your turbo you will have shit load of lag

Warlord You got luck bro..................

You never know what is wrong with the unit when it is second hand .....

there has been alot of story of people buying dud

I think it is time you look at others than the Pfc

dont get me wrong the PFC is the best ................... But now there is better

I've never heard of a 'dud' power FC purchase to date, not that it may not happen, just seems to be by far the exception ot the rule.

Searching this forum you struggle to find someone complaining of a dud purchase....

rev m8...............................

I bought a brand new PFC in novemeber and it was a dud.....Luckly i bought it from a dealer so there for i go my money back. there has been heaps of story of pfc being duds and yeah for tuners.........................these are computers the bound to be faulty

Anyway i hav now in my car an EMS 8860................. it is rated highly and my car is done at bel garage and the masters at tuning....

Pfc are still the best comps around but the becoming rare.

      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...

      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.
