R33 s2 1996 missfire

I brought this car 2 days ago and between 5500 and 6000 rpm she missfires the owner before me had put spark plugs in the car that were 4 dollars each, i went to auto one and they said they should be 25 each the engine being a rb25det would this be why she miss fires??

Any help is appreciated!? thanks in advance

No, check the gap on the spark plugs. 0.8mm is what you want. The $4 spark plugs are fine,  BCPR6ES or BCPR7ES is what you want. If it still misses at 0.8mm your coilpacks probably need replacing. If its stock ecu you could be getting r and r. This happens if the ecu detects too much airflow and tries to protect the engine by dumping fuel in it. Try turning the boost down a bit to say 7-8 psi and see if the miss goes away. Try all that and report back, cheers. Buy some new $4 sparkies while you're at it and make sure you get the 0.8mm version BCPR6ES, not BCPR6ES-11

+1 for regapping plugs

I had the exact same problem after putting in cheap copper plugs and running 10 psi (felt like a spluttering and loss of power after certain rpm).

I gapped the plugs down to 0.8 and wrapped the coilpacks in electrical tape and the problem went away.

The shop said to get the expensive ones, who'd have thought it......

For future anyway, the advantages of Platinum are the longer service intervals (I think they claim 100,000km on the plugs) which makes them sound good. This is all well and good on a mazda 3, not so much on a modified Skyline. I perfer to change plugs more often so its cheaper just to get $2 copper plugs and change them more often

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..

      Lower A arm Skyline v35

      By sonicii · Posted

      The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.

      Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????

      Thanks Paul I reached out to Autotainment but they no longer work on JDM cars as the guy who used to do the work moved on and is no longer doing that kind of work. I am talking with Level Up Audio though.
