So I reckon I have just about finished modding this car now.

Bought it about 3 months ago changed all the fluids, did timing belt, serviced auto trans ect. Replaced sparks and then coils with splitfires as stock ones were mis-firing. That got it running normal. Then did a full 3" exhaust, FMIC, bumped the boost up to 11psi. Bought a SAFC NEO and had it tuned the other day. First few runs it wouldn't do over 148rwkw, then tuner realised fuel pump was stuffed. Put in a high flow pump and tuned the NEO and it pulled 199.3rwkw. Car is much nicer to drive now, pulls very hard throughout the rev range - my Apexi RSM is showing a 1 second improvement in 80-120km/h roll on after tune and it is now 0.8secs faster to 100 than before tune. Hoping to get down to WSID on Wednesday night next week to see what it does down the strip.

When I first bought this car I didnt want any mods, but then one thing leads to another.....ect

Anyway car is a daily so dont want to do any other power mods - as far as reliabilty goes is there any other supporting mods I'm missing? - I want this to last me a while.

That's a pretty good tune with the NEO considering it doesn't have much to play with in regards to timing.

My advice would be to get a transmission oil temp gauge, as a rule of thumb I have to wait until the Engine oil is 90c before I know I can give the car heaps without the auto slipping.

A temp gauge on the gearbox would let me know when the time is right, quicker :stupid:

Trans and dff should be OK at that power level without crazy abuse (shoving in D from N) and that sort of stuff. I've had 2 auto R34's over the past 6 years and neither showed signs of gearbox trauma...even the N/A that was boosted.

wow impressive tune,

how much did the safc neo set ya back (( that is the computer that was tuned right0?

Yeah NEO (piggyback air/fuel controller) was tuned only. PM sent on price i paid.

Have noticed quite low oil pressure the last week at idle - I started a different thread on it, really hoping its not something serious...

Why is your tyre presure 50?

Secondly how do you rate Race solutions to tune a skyline as we know they specialise in rotaries.

No idea on the tyre pressure, Hitman did the tune - I went with him after recommendations from others on this forum. Dyno figures can say whatever, but the RSM dosnt lie (relativley speaking in terms of improvements in times) so I'd rate him very highly.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Strange issue RB25DET wont start

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      By GTSBoy · Posted

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.
