Hi all

It's my first time posting in sau as i recently purchased an NA R34 with an aftermarket turbo.

First of all, can anyone recommend a good tuner (preferred specialised in skyline bnr34) in Melbourne? I would be getting the car retuned after fixing a problem that it currenly has.

Secondly, so the problem it has now is that it can rev upto redline on P mode but when driving the rev caps at around 3000-4000. Up to this point i think that either there might be something wrong with the AFM, or i have to install the aftermarket fuel regulator and fuel rail back into the car as i think it could also be the problem from the fuel pump. However i am no specialist in cars so if anyone of u guys can give me anyhelp that would be greatly appreciated.

The previous owner did told me about this rev-capped problem and gave me the aftermarket fuel regulator and rail, however i am not 100% sure if that is the solution to the problem so i am wondering if the problem can be easily fixed by a professional tuner/mechanic incase if it is something non-trivial.

Also, both the fuel injector and fuel pump are aftermarket and not stock, the AFM i believe is a Z32 AFM.

Cheers

Also that car sounds butchered.. stock RB25DE ECU with a turbo slapped on it.. don't dick about with the fuel reg or mixing and matching shit without an aftermarket ECU or at least a piggy back (as you have an auto)

Sounds like you bought a problem. Which is why the guy sold it.

Prepare to open your wallet.

hmm prehaps not as bad as u thought,I've had my mechanic looked into it and he thinks there's no big problem but it just take time to find this rev-capped problem,which is likely to be either afm or fuel related.

The car has GReddy emanage ultimate ECU since it's an auto as well as many other mods with over 10k receipts, so I am wondering would a professional tuner be able to diagnose the issue better for me?

Yes a tuner would be your best option

Sorry my bad for creating multiple threads.

Also, apparently Chequered Tuning doesn't tune emanages anymore. Is there any other suggestions? Thanks in advance.

I would suggest getting an Adaptronic e420D and splicing it into your loom to control injection/ignition and letting the OEM ECU control the automatic box.

That "rev cap" as you call it is actually a TP Load cut.. your ECU is going "wtf.. why is there so much air going into the motor, I'm cutting fuel"

Talk to Trent, tell him the bastardised setup you have and someone from SAU recommended using an Adaptronic e420D to make it boogie.

I tried, unfortunately the guys from Chequered Tuning said Trent wont be able to talk to me over this matter, as apparantly he doesnt get involve with emanage anymore ;/

      Rb25 trigger kit and timing misalignment

      By drifter17a · Posted

      The trigger kit I have is similar to the one in the link below. While going through Facebook, I saw someone else mention a similar issue, and I’m starting to think this could be related to the crank gear itself. I understand these parts are CNC machined, but maybe some earlier versions or individual pieces might have slight inconsistencies—it just doesn’t look right in my case. https://www.facebook.com/share/16an8evZd9/?mibextid=wwXIfr I originally installed the crank gear using the thin OEM washer, but as shown in the attached photo, the timing belt walks very close to the edge. When I tried using a Nitto washer—which is thicker—it actually made the issue worse. The belt walks about 1mm off the front edge, which raises more concern about alignment.   I’ve gone through the full process of elimination:   The tensioner pulley and bolt are brand new and installed correctly. The bolt isn’t bent and is oriented properly. The back of the tensioner and the idler pulley are clean and seated correctly. The idler sits slightly more forward, which I understand is due to its design. I’ve experimented with both tight and loose belt tension, but it makes no difference. As soon as the engine runs, the belt immediately walks forward again—even if I reset it beforehand.     At this point, I’m considering replacing the crank gear with your Race Version 1 (12-tooth), but before purchasing, I wanted to ask:   Are you aware of any alignment issues when using this gear? Would this gear help keep the belt aligned correctly, or could the walking still occur? Does it work with a standard missing-tooth crank and rear washer? Is there any specific crank setup or install procedure required?     For reference, I’m not using a front washer, as the PRP crank gear seems to replace the need for one.   Looking forward to your advice.

      Yep, looks that way. Never driven an E30 or R31 so I can only imagine

      Yuh, My new R34 box is sitting on the workshop floor (in its large shipping box, which is a nice thing on its own), along with a front plate to convert to push clutch. There was no way I was interested in rebuilding my existing one. Was only partly interested in the risk of buying a used one. But, if you want a 2nd hander, I can point you to one in/near Melbourne at least. @Komdotkom has one that should be in good enough condition to be usable. I don't think it's in a for sale thread, you'd have to message him. @redzedhas one that definitely needs a rebuild.

      I used to love going to Amaroo to watch the HQ series go for broke (eventually stopped due to lack of spare parts) and also the Porsche series.  It was so cool to back your car up to nearly the edge of the viewing barrier and party with your friends, having a bbq and alcoholic/non drinks. It was such a family/mates atmosphere
