I posted a thread the other day about my exhaust temperature sensor (http://www.skylinesaustralia.com/forums/index.php?showtopic=103482)

Since i re-screwed in the sensor it ran fine for a day but now the warning light is flashing again, its not the engine light the symbol looks like a cat converter with steam coming of it, i assume its a temperature warning light. Since this light is still coming on and off while im driving does that mean that i have to replace the sensor cause its damaged? (since it got filed dragging on the road) if so how hard is it to replace (can i do it myself) and is it an expensive item to buy? Is damage going to be done to the car if i keep driving it with the warning?

The second problem is from what ive read is common but i just need clarification. When im driving my car a bit harder (above 5500rpm) it stuters a bit under boost and the revs are not smooth to the redline. From what i can remember it is most likly the spark plug and or the coil packs that have given up and can no longer provide a good enough spark under high boost pressures. Is this correct and if so what sort of price am i looking at to get new plugs and or coil packs (splitfires etc) and how easy are they to install can they be done by most people? or are they more a job for an experianced auto electrician?

Any help regarding these question will be appreciated, thanks in advance.

Just did a bit of searching and found out that the exhaust sensor is not needed and wont cause a problem so i will remove it all together and plug the whole.

I would still like conformation on the second question regarding inconsitant revs, is it the coil pack and or spark plugs?

$25 for a set of plugs will answer that question

I had that Exhaust Temp Sensor light on in my GTR for a while, not long after I had new turbos fitted, the car started running like a dog and the Cat was steaming! (Cat and dog reference pure coincidence! :P )

So initially I thought the Cat internals had melted...and well...had it removed.

Car still ran like a dog and would only run on the smallest of throttle openings.

To cut a long story short, I stumbled across the problem when removing the Plastic cover which bridges the rocker covers on the RB26, Not long after having new turbos fitted I painted the rocker covers, and had removed this panel, when putting it back on I did not plug the ignitor back in properly (Mounted on the panel) hence the plug came loose and car ran like shit.

Put the plug back in and No problems to this day!........

As mentioned, plugs around $25, Splitfire coilpacks around $600 depending upon how you source them.

Plugs are super easy, coilpacks come off to access the plugs and from memory they are plug and play also.

DIY approved! :D

You're welcome! DIY always starts with oil changes and plug changes and you try harder stuff from there. :) I'm a DIYer too.

There is a well illustrated guide on www.niztek.com (or .au?). I found removing the ignitor plug to be the hardest, but my car is a lot older :(

      New lightweight, square wheel/tyre combo for the E90

      What type of track driving will you be doing?  Do you have a set of class rules you need to abide by that will limit your rim / tyre width?

      New lightweight, square wheel/tyre combo for the E90

      By PranK · Posted

      I've been reading a lot lately about unsprung weight and how beneficial it can be to reduce it for driving on the track, given my semi's only have another day or two in them I am throwing around the idea of some lighter wheels and a square set up. I have 265/35/19's and 245/40(?)/19 Federal 595's at the moment. The wheels and tyres are super heavy. I looked up my wheel weight online and got 14.5kg naked. Not sure if this was 8.5 (front) or 9 (rear) but that's a lot. I have also been reading about the benefits of a square setup. Much better rotation and potentially less understeer.  When I throw these together I'm thinking about a 17x9 or 18x9 square (preferably under 10kgs per wheel) with 245 or 255's. I can get some cheap 17x8.5 BMW M Sport wheels, they weight 10.5 kg's each but at 8.5 wide could probably only get 245's on them? I know they come with 255's from factory but semi's are a bit chunkier. Otherwise it will be aftermarket wheels in a 9" width. Most of the other BMW wheels are heavy unless you pay a squillion dollars for some M wheels.  Although, the E46 M3 Style 67's could be good but I'd have to buy 2 sets to square them up.  My car has a tickle over 400hp and about to put an LSD in also, is 245 a little thin for a square setup? It kinda feels that way to me. Also, is there any tangible benefit to having 18's over 17's? Is the footprint demonstrably bigger? From those of you who went to light(er) wheels after heavy buggers, did you notice it much?

      RB26dett R33 gtst swap

      By GTSBoy · Posted

      Start with the R32 GTR wiring diagram. The ECU is essentially the same, so the pinouts are good. The details around ECCS relays, etc might differ a little bit, but the reality is that you need to get ignition power to kick the ECU so it powers up the ECCS relay which brings the rest of the ECU up. This also gives power to the other circuits that are needed to make the engine run, like the ignition coils, etc. All of this is visible on the R32 diagram and should give you a strong guide, even if it's not quite the same as the R33. As to specifics - I'm pretty sure no-one can help you from afar, as there is no way to know what mistake or omission has been made in connecting stuff up. It always turns out to be "LOL, I shorted something and an entire wire vanished out of the loom", or "We never connected X or Y main connector", or "shit, you mean I need to have that fuse installed?".

      hahahaa @GTSBoy that is my last resort. Like use a cardboard and cut it using the indicator as a reference. But I was winging my luck to see anyone had a spare bumper because drawing the outline off the hole is always easier and less chance of mucking it up
