SO this is where i am up to now.

MUST READ THIS FIRST

http://www.skylinesaustralia.com/forums/in...151261&st=0

I have checked a few things and going to do alot more checking arround. BUT i got new splitfire coils, from SLIDE, and put them in and the car still misfires. I have the stock ECU with an SAFC II tuned by kutz, and all seams ok, but i still have to run .6mm gap so that it doesn't missfire, now that sux.

Can somone help me, where can i get my splitfires checked out to see if they are ok, and what else should i do?

Hay toffy, i did the folowing last night.

CAS out and tested, correct opperation and correct voltages.

Pulled out the coil loom, correct voltages, and no bad earths, all trigers correct. Coils gettign 12.4V and triger 10.2V.

All injectors correct, work as per manual, triger correctly.

Now back to 0.6mm gap and see how that goes.

I am so fed up, this sux. Sorry all sprakplugs are new too.

How did you check the injectors cobber???

I know that when my car started to miss cause of a fuel misshap when i pulled them out and got them check that 2 were knackered when they looked ok!!!

Have you check each coil indiviually to see if it just a dodgy one???

Honestly it doesn't sound like it was the stock coils giving you grief to begin with!!!

Well i haven't pulled the injectors out, just did the test in the book, voltages, resistance, and pulsed each individially, the thing is each plug looks exactly thesame, no leaning out or nothing. There are no leaks of any sought. The thing is too, it would be missfirying at the TOP aswell but it does not.

Well i am oly doing what seamed logical, i mean the coils were definatly shot, the old spark looked like something geriatric.

The car performance is definatly better, easier starts, better idle, and fuel consumption is up aswell.

I don't have the money to do much more right now, but i might have to look into the injectors.

BUT talking to KUTSI it definatly spark related as it happens at the peak cylinder pressure. So who knows. i think it's electrical, in regards to spark.

It certainly sounds electrical cobber.

You changed your ECU didn't you, do you still have the other one to try and see if that makes a difference at all???

My 33 had been playing up for a while backfireing and the engine cutting out. Thought it was to CAS but changed that and it was still doing the same thing. I finally found out the the plug that joined Haltech to the factory loom was a little loose and the connection would cut out and kill the engine.

Just something else to check.

After all that. I'd replae the old wiring loom (ignighter module to coil packs), with new fresh wires, of a larger size(there can be a performance gain as well). I'd replace your ingiter module, permanently. Then index your plugs, for height and point the gap (in the plug) at the intake valves (just mark a line on the ceramic with a texta....

Well i will check the connection plugs, but all seam preatty good, will do.

In regards to ignitor, i have a S2, and do not have it, it's inbuilt to the coils.

Does anyone have a S2 loom i can borrow overnight to have a look, i did check mine and it seamed ok, no lose conections or anyting, all good earths.

CAN YOU tell me what the plug indexing is, i think i understand, you mean point the electrode tip towards the intake valve, correct? How do you know if it is going to be the correct way in the head? ALSO what do you mean index for height?, ensure that all the plugs are the same spark gap, or hight of electrode?

SO DOES anyone have a loom i can borrow?

      HKS stroker kit step 0/1 or HKS GTIII 2530

      Definitely the stroker kit. once you mention you have a RB28 everyone will assume you will flog them and hopefully won't start asking about support mods. Anyone will be too scared to race you, except maybe the RB30 boys

      R32 GTS (RB20DE) clogged cat

      By GabsReDeal · Posted

      Just a quick update: I decided to go ahead with the de-cat for now. The exhaust shop inspected the catalytic converter and said it was in good condition. I took a look myself, and it does not appear broken nor clogged. After the de-cat, the car feels more responsive and smoother. The shop also reinstalled the exhaust temperature sensor into the de-cat pipe, and now the warning light no longer comes on, even when driving hard. The only thing that’s bugging me is the tinny, “can-like” sound the exhaust makes now (similar to having a hole in the muffler). The shop suggested that I might need to replace the muffler. I'll have to think on what to do next.

      I want to start upgrading but don't have the budget to drop 15k at once, if i was to do one first which would be better and why?

      Ceramic turbine damage to engine - what did yours do?

      By GTSBoy · Posted

      Yuh. It is very rare for a single turbo to throw ceramic into the engine. Quite common on GTRs. As I posted above. Mine did destroy the O2 sensor on the way out though! Plastic compressor is fine with the temperature. It's not some flimsy PE/PET/PP thermoplastic. It's a thermoset resin with reinforcing material in it (a composite, as posted by @Lithium above). The compressor never sees much more than 100°C because it's never boosting very high. If you boost it high enough to make a lot of temperature, then the turbine will depart the scene and stop the party anyway.

      From what I understand, it's a ceramic turbine and a plastic compressor (not sure how it doesn't melt then lol) I heard the series 2 r34 gtt has a metal turbine but I doubt that. @GTSBoy When you blew your standard neo turbo it didn't cause damage from memory just the turbine ended up in the cat?
