After reading a few posts about the coil pack issues i was wondering,

1. How much for new set of coils

2. Where can we get them from

3. Watt brand (Spitfires/Genuine nissan ?)

Also O2 sensor & crank angle sensor....how much and where can we get it from?

................................................................................

..........................................

I got my car dyno yesterday at Jem performance at Moorebank NSW

but I did the following before the dyno,

1. New fuel filter(coopers brand)

2. New BCP7E NGK Spark plugs.....(no adjustment on gap.. kept standard gap)

3. Reset the ECU

It was dyno at 134 kw. A few adjustments and i got 145kw safely.

Yes my car has got a pingin issue and missfire.

................................................................................

..........................................

I will try the following now;

1. Clean the injectors out (my car has done 101,000 km now)

2. Seal the coil packs (with either Araldite or that dialetic grease)

3. Change 02 sensor

4. Change crank angle sensor (? not sure about this one yet)

I will do each in stages to c if there is any change between these items do.

maybe we can hopefully isolate something.

Have i left anything out?

What do u guys think?

I've been searching for O2 sensors too, and from these threads, lots of people have found that EL ford falcon sensors are a swap over, albeit with a bit of wiring. They range from $80-$120 from places like repco & autobarn. Aparently the wiring has a diff harness/clip, so you need to cut it and rewire. Seems pretty simple. This is what i'm doing later this week.

Hope that helps.

Looks like you have covered the common stuff.

They are a cam angle sensor also, not a crank angle sensor. Not that anyone gives a crap, but sometimes helps when ordering parts.

What boost level VS timing are you running?

What mods do you have?

ok...... GTR Killer thanks. Thinkin of VL's too much.

I started on my Injectors yesterday. I took the whole Fuel rail out and sent it in with the injectors in it to be cleaned.

I found that in the manifold...the last 3 sections inside the manifold are quiete darker in oil.

I am talking about the last 3 manifold sections closest to the fire wall.

The first 3 are clean as.

I am thinkin o gettin the head ported and polished a little ...while i have the stuff off.

Not sure yet what to do.

With that info I would have to definately recommend a head service which you will get with a port job anyway. The valves have to come out to do the porting so they will re-seat them and replace the stem seals. You will most probably find the nature of your problem once the head is off. Make sure you check your pistons for bore travel just to be on the safe side and check them for pitting or any unusual marks. Make sure you find out what's causing the darkness before you go ahead with the port job. Also make sure they do a full check on the head before proceeding. I know of a couple of places who would just start chopping without checking.

Another thing about porting, on this vehicle it is not advised to extend the head VS manifold area. This, I have been told, is already quite large compared to the capacity of the head. Depending on how far you wanna go with it. Sure, if you have the turbo to match it, then open her right up, but be prepared to open your wallet at the petrol station. If you are going to open this area, make sure you match port the manifold to suit it otherwise your efforts are wasted. Most of your power gains will be made from cleaning up the bowl area below the valve. Do not underestimate such minimal work, you will be surprised at the results.

Polishing is a bad idea....good in the 80's but reasearch tells us that pollishing the heads and manifold is actually bad for performance. You will lose horsepower with a polish.

There is a huge thread on O2 sensors stickied at the top of this section.

Get N15 pulsar plug, $90 from motortraders (trade price) and comes with plug. Plugs straight in, no fixing wires :/

I just got one and definitely does fit

don't see the point of owning 2 cars as the missus and i both work at the same spot (at my business), and her car is fast enough (will beat natro skylines, lol), and is cheap to run, and tows my tinny well enough, so no point paying $1000 in rego and insurance a year for a lawn ornament.

oh and the bicycles comment was based on the fact i own a bike shop.

      AHHHH gotchaa, I'll do that once I am home again. I tried doing the harness with the multimeter but it seems the car needed a jump, there was no power when it was in the "ON" position. Not sure if I should use car battery jump starter or if its because the stuff that has been disconnect the car just does send power.

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.

      spot the stagea

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.

      In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
