It's the resistor pack for your injectors. Its there to change from high impedence to low impedence. If any wires are shaved, try repairing it. This unit can be removed for repair, but for now lets try fixing the problem you have now.

Check No.1 coil very carfully - something might be there

Photo's are there now.........

i already got a new set right here! i just bought some extra ones last time i changed'em,

but they are the same ones ( NGK BCP7E-11 )

also, is it ok if i kept the gap as it is? coz i never gaped one b4, and if i try and end up breaking one am going to be a plug short! hehe!

btw, i couldnt thank you enugh for ur time. uve been a big help

No problem, thats one of the reasons why we are all here, share, talk & help.

Your plugs must be gapped down, its not hard it you have a filler guage. I can guide you through it if you like.

been reading a few threads, and i found this one:

almost the exact semptoms. i realy hope its not a gasket

OK, I have read this post. This is true - if your car runs very rich, it will misfire but if you replace the spark plugs - as I have suggested - it will run fine for a while until it misfires again but we at least know where to start looking.

In any problem solving, process of elimination is your friend. We have to check what works to find out what does not.

P.S. Gapping plugs with even a good Mallet, hammer, brick is a health hazard....... only qualified professional machanical engineer technican should use these devices.

is this what your talking about? coz i found one! loool

Thats the one!!!! Even people like you and me can use this, no qualificians necessary.

1. find 0.6 filler guage.

2. on something soild like a metal bench, tap the spark plug with just enough force to shorten the gap.

3. Contine doing this & check with the filler guage.

4. If you over do it just use the filler guage or something else to very slightly open it up.

5. The filler guage should slide in without moving about or move very slightly.

In your situation because you have 1.1mm gapped plugs, measure from the tip of the spark plugs, they have to be bent a far bit - this is why the BKR6E has a factory setting of 0.8mm gap, better and easier to gap to .6 or .7. Another thing, the 6 is a hotter plug, does not foul as easy as the 7 plug range.

0.6 is probably a touch to small, the gaps on modded GTR's i've heard used are usually 0.65mm-0.8mm... Not sure about 0.6mm but can't imagine it making a huge difference either way - why not aim for the middle of that - say 0.7mm?

oops sorry, I meant 0.7 as your other spark plugs were gaped at these & 0.7 is a good gap to keep. Mine are at 0.6 but I have alot more boost & fuel to iginite.

Sorry about the confusion

    • GCG is a good company, they're a major distributor for Garrett in Japan as well.
    • Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣
    • I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).
    • Ok thanks 🙂 I will higly consider this. Any "known" company for a good reviews and experience to send that off? Is that CJ-motor good one? Or go straight to GCG site? I need to use VPN to even find some of those "shops" let alone access them 🙂 
    • You can literally put in as much WMI as it takes to quench the combustion totally (and then back it off a little, obviously), and it will keep making more and more power. The power comes from the cooling effect of the water (and the meth) and the extra fuel (the meth, which also has massive octane). It is effectively exactly like running E85. One might be slightly better than the other, but they are damn close. But with either you can lean on the boost or the timing (or both) waaaay more than with just petrol and the results are similar. Here's the first thing I googled for an anecdotal bit of evidence. Can't access the attachment without being a gold member, but it is there for the getting if able to, or searched up elsewise perhaps. https://www.hpacademy.com/forum/general-tuning-discussion/show/wmi-vs-e85/
