Hey there,

Some of you may know I have a problem with my R33 at the moment, seems as though it is missing, anyhow thanks to help of people here they said either the Spark Plugs, ECU or Fuel Filter would be my problem.

Now I'm just in the process of taking the Spark Plugs out to check them, now I just want to make sure I've got the right plugs here.

They say on them:

NGK

R

PFR5G

11

Yeah, they are irridium plugs and apparently RB's don't like them too much.

Car only has the following mods:

- K & N Pod Filter

- Cold Air Intake

- Forged Pistons

- Strengthen Conrods

- Blueprinted

- Balanced

- Port Polished

- Metal Head gasket

- Spitfire Coils

- High Performance Timing Belt

- High Performance Spark Plugs

- Gready Turbo Timer

Everything else is stock, stock ECU, stock boost etc.

Use these plugs I have never had a problem

with them and so has many other R33's

In regards to your previous thread,

concerning your missing issue.

I would check your coil packs for fine hair-line

cracks, which release the current as they heat-up.

Resulting in an insignificant spark that does not

ignite the combustion chamber(s) properly.

Hope this helps,

Cheers,

Bill

Is the number 11 the heat range? If so, is that right? What should it be?

Everyone is telling me different plugs, I don't know what ones to buy tomorrow ..don't want to trust Autobarn either.

I've been told use:

BKR6E Gapped at 0.78 or BCPR7ES

Not trusting them is like saying you dont trust the NGK listing, which is fairly good considering NGK make genuine Nissan plugs.

They will list Platinum plugs for your car. Highly doubt they will have BCPR7ES on shelf tho.

As you already have splitfires it eliminates coil problems as you have stated.

There's nothing wrong with the plugs you have in there now for the turbo and boost you are running. Gapping them down at stockish boost levels is pointless, it's usually just a mask for dud coils.

I suspect your problem lies with the stock ecu running into rich and retard, which in turn introduces a rich miss. A colder plug as recommended above will make the problem worse as it is more sensitive to over fueling and fouling, particularly at lower plug gaps.

As a first move, gap your existing plugs down to .9 or so and see what happens. Then get the car to a dyno for a power run and see what the mixtures are like, while it's there get the fuel pressure checked at the rail to see if your pump or fuel filter is dead/dying.

Just for reference, i run splitfires, 20psi and 7 heat range plugs at .9 gap with no miss/fouling issues.

good luck!

edit; looks like you posted while i was writing. congrats on the find. almost certainly the problem. Just so you know, plugs don't just burn off electrodes for no reason....

Id be more worried now what damage the pissing part of the plug did to the cylinder, the piston, and possiably more parts of the engine.

Thats what I am worried about now, esp after I forked out 6G's for a Forged rebuild.

What would have caused the plug to do this? It was only 1-2mts old.

Yeah, thanks for writing all that up though.

Now I need to find out why the plug did that and why, it is wierd I've never heard of it happing before. Anyone know what I should do now - anything I need to check before putting in a set of new plugs?

    • It is a kunfine Android screen . Does anyone know the wirering diagram of the fuga ??
    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
