Just curous to know if anyone has tried to drive their car with the instrument cluster unplugged and removed. Obviously she has a few inputs from ecu for rpm etc etc, but do they have any outputs that are used for any function?

I know when my speedo cable failed and the speedo on my dash didnt work, it caused drama with the HICS computer as it wasnt geting its speed reading...though i suspect this was an issue as i imagine it talked to the ECU not an output from the cluster.

So anyone know, i cant try as i dont currently have my car and need to know so i can make some changes to one

I had my cluster out once to get fixed ,and noticed that when i drove it without it ,my hicas or power steering not sure ,made the steering very heavy and weird.Soon as it was plugged in again every thing went back to normal.But i do know that having the cluster out seems to make a few things funny.

So it would seem that the speedo cable into the cluster actually gives an output to the ECU for road speed and hence the HICAS computer, which even if yo have the rear sterring disconnected, still upsets the normal power steerign operation.?!?!? as i noticed the same heavy steering thing when my cable failed.

Hmmm, butchering cars is never easy.

Thats I think that is what I was noticing with no cluster in my r33.

I was just putting around the suburbs so probably didn't kick too much past 80km/hr or so, but at low speeds I didn't notice any funniness with the HICAS or power steering. It was driveable anyway. "Guessing" the speed was a bit of a gamble as well but made things interesting :thumbsup:

Also disconnecting the hazard button means the indicators won't work on an r33 - so I assume its probably very similar for r32. So make sure you keep the switch plugged in if you want to indicate.

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
    • There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again? 
    • I haven’t yet cut the chassis, maybe I switch to a reverse flow. I’ve got the Intercooler mounted as I already had it but not cut yet. Might have to speak to an engineer 
    • Yes that’s another issue, I always have a front mount, plus will be turbo plus intake will big hasstle. I’ve been told if it looks stock they’re fine with it by a couple others who have done it ahahaha.    I know @Kinkstaah said the stock gtt airbox is limiting but I might just have to do that to avoid a defect so it atleast looks legit. Or an enclosed pod so it’s hidden away and feed air from the snorkel and below Intercooler holes like kinstaah mentioned. Hmm what to do
