V35 Issue - Desperate Need Of Help

Hello Guys,

I've been having this problem with my V35 250GT for some over 6 months now and the car is now sitting at a well known workshop where the mechanics are stuck so I've come to the forum to ask for assistance.

6 months ago I had my VQ25DE engine replaced with a new one, since then the car has had issues on full throttle and the mechanic who installed the engine closed up his shop.
I took the vehicle into Nissan and they said that there was a TPS Error code being thrown up on their diagnostics tool, they checked the TPS and saw the wiring had been hacked so they tried to fix it up.

This solved the problem for about a month and then the car started to feel almost like it hits a rev limiter on full throttle and the whole car shakes, it drives fine if you lightly accelerate all the way up the rev ranges.

I've been battling with the issue for a few months because nobody knew the answer to the problem, until a few days ago when the vehicle does the same on about 2,000 RPM's now and is practiaclly undriveable.

Another scan has thrown up a curl valve error (apparently sits at the front of the engine to open and close throttle) but again, the mechanic is not 100% sure without another V35 side by side to replace parts and test.

If anyone can help, please help as I am stuck and left with no other options. Even if someone can lend HyperDrive in Malaga their V35 250GT for a cost so that they can test replacement parts I will be forever thankful.

Cheers Guys!

I have a spare section of the plenum with the tumbler valves in it, if that's what you mean, or are you talking about the throttle assembly?

I would be surprised if it isn't the AFM causing the fault though. I have replacement's here but until you know the cause for sure, you are grasping at straws. You need to get a consult 3 unit on it, to read the ecu properly.

      ER34 AT ECU and HKS SLD pins

      By GoHashiriya · Posted

      Hi all, I need to get this HKS SLD attached to my stock ECU because I've now got the German autobahn and faster European circuits to contend with.  The car is a manual 2dr ER34 with an AT ECU and I've realised the AT ECU has two pins for speed sensor signals: Pin 29: Vehicle speed sensor signal (Vehicle speed sensor 2) Pin *58: Output shaft rotation sensor signal (Vehicle speed sensor 1) - *RB25DET A/T model only Before I go butchering this harness, is anyone sure of which pin is the correct one for signal adjustment? The attached document from HKS indicates pin 29 but I found this situation mentioned in the following thread on a different forum (R34 GTT Auto Trans Speed Cut Problem | Zerotohundred) mentioning pin 58 needing to be altered by member zephuros, albeit it seems to be for an RSM-GP and the info appears to be old.  R34_All_Workshop_Manual-pages-2.pdf R34_All_Workshop_Manual-pages-3.pdf R34_All_Workshop_Manual-pages-1.pdf HKS SLD Vehicle Pin out P59-P70 ER34-pages.pdf

      Slimline sub on the rear parcel shelf is doable. Pioneer TS-WX140DA is only 70mm high.

      Rear suspension upgrades

      By GTSBoy · Posted

      People like Johnny Dose Bro might be laughing at my post because I accidentally added 100mm to my numbers. 350-355 is indeed the lower limit. 450 is off-road Skyline spec.

      What is the "compromise" that you think will happen? Are you thinking that something will get damaged? The only things you have to be concerned about with spherical jointed suspension arms are; Arguments with the constabulary wrt their legality (they are likely to be illegal for road use without an engineering certificatation, and that may not be possible to obtain). A lot more NVH transmitted through to the passengers (which is hardly a concern for those with a preference for good handling, anyway). Greatly increased inspection and maintenance requirements (see above points, both).   It is extremely necessary to ask what car you are talking about. Your discussion on strut tops, for example, would be completely wrong for an R chassis, but be correct for an S chassis. R32s have specific problems that R33/4 do not have. Etc. I have hardened rubber bushes on upper rear control arms and traction rods. Adjustable length so as to be able to set both camber and bump steer. You cannot contemplate doing just the control arms and not the traction arms. And whatever bushing you have in one you should have in the other so that they have similar characteristics. Otherwise you can get increased oddness of behaviour as one bushing flexes and the other doesn't, changing the alignment between them. I have stock lower rear arms with urethane bushes. I may make changes here, these are are driven by the R32's geometry problems, so I won't discuss them here unless it proves necessary. I have spherical joints in the front caster rods. I have experienced absolutely no negatives and only positives from doing so. They are massively better than any other option. I have sphericals in the FUCAs, but this is driven largely by the (again) R32 specific problems with the motion of those arms. I just have to deal with the increased maintenance required. Given how much better the front end behaves with the sphericals in there.....I'd probably be tempted to go away from my preference (which is not to have sphericals on a road car, for 2 of the 3 reasons in the bulleted list above), just to gain those improvements. And so my preference for not using sphericals (in general) on a road car should be obvious. I use them judiciously, though, as required to solve particular problems.
