If anything what are you using to amplify/boost the spark in your RB. I have an RB25DET with stock coil packs (have a newer set of RB26DET coil packs to replace them with) but I want to get maximum spark. So I’m researching what has already been done so that I can choose the best option for me. Thank you in advance for your suggestions.

There are plenty of options, and some threads on here.

Why do you want maximum spark? Do you have miss fire issues? a boost spark won't equal more power unless you have an ignition related misfire.

I seem to have a slight misfire under hard acceleration from low rpm. If i accelerate normally than everything seems to be fine. I'm going to be running some test of the coil packs when it gets a bit warmer, it snowed here in Atlanta, GA (USA). I will be working to confirm that it is a misfire. I have a set of RB26 coil packs that I'm going to make sure a cleaned up in top notch shape. I have seen some things on applying liquid tape to them and wrapping the extensions with electrical tape to keep them form grounding out. Also the car seems to have a bad idle after getting to operating temp. I think that may just be poor idle setting or tune. I will be checking into that also. I did not think to state that the RB25DET is swapped into a 1995 240sx S14. I guess my thinking was to optimize spark for smoother running motor by really making sure the fuel gets burned well.

If there is any fear/worry that your coils are not working right, I wouldn't bugger around with 2nd hand coil packs. Just buy some new OEM coils or a set of Splitfires and be done with it.

I hear you on that. A good friend of mine now has an RB26 and is going with the LSX coil packs for his ride. He gave me the RB26 coil packs in trade for an busted ka24de engine block. I'm going to have to save up a bit more before I can get some new ones (this summer). This is my first RB so I'm trying to do my homework, ask the right people the right questions and then do what is right for my ride.

Std new oem coil packs (not the 300 dollar sets on ebay which are copies) and irridium or platinum plugs gapped at 0.5mm will support close to 1000hp. Split fire and the same plugs will also handle more HP than most will ever need.

Sad part is none of the Nissan dealerships I have access to say that they can get any Nissan Original Parts for and RB. I have options but they all equal me spending $400-$500. That is what I get for going with the RB vs the SR. My goal is not high (350 rwhp) so stock ones will do the trick. Thanks guys I'll source a set and go with those. Would you still add a spark amplifier once you get that or not needed at that point?

And thank you everyone for answering my noobie type questions.

    • Hi 🙋‍♂️. Just bought my Unicorn but the interior need some minor work so it would match my expectations ;). I noticed it is hard to get used oem floor mats in good condition so i started to dig if there's any chance to buy set of new ones. I found two websites - nengun and amayama and it looks like one can still buy factory new floor mats in Japan, but thers a small issue. Some mats (i assume genuine, oem ones) are marked as G4900 and these are "discontinued". The ones you can buy are marked as G4911 but i have no idea if these are also oem, made by other producer or some lower quality replacements that looks entirely different. Can anyone help? 😃  P.s. there is also some strange indication - 0V005, 0V015 and 0V505. Any idea what does it mean? Would appreciate any help with this 🙏
    • Hi, Marek here 🙋‍♂️. I finally fulfilled my longtime dream - recently bought Stagea and now waiting for it to arrive in Poland. There's only few of these in my country, and one of the owners  recommended mi this forum as a source of all the info i'd need since now i own one  so here i am.  
    • Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though
    • and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.  
    • Oh, you are right. But, in Australia E10 is based on 91RON fuel and ends up being 94RON. Hence it being the cheaper option for economy cars. The more performance oriented cars go for the 98RON fuel that has no ethanol mixed in. The only step up we have left then at some petrol stations is E85.
