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.

      Yeah, my moulds and seals are 32 years old now. I think I will continue to not use a pressure washer on it.

      I hear the old "I'd never use a pressure washer on my motorbike" BS in the dirtbike community too.  The only people that have had a problem from using a pressure washer on anything are the people that aren't using them properly.  If you hold the wand any more than 45 cms away from pretty much anything (radiators, wiring connectors, paint, etc) you aren't going to cause any damage.  We've had detailers wreck moulds and seals on cars at work before and the only reason why is they held the pressure washer too close and on the one spot for too long.  If you have 5% more brain power than a detailer then you know not to not do that and you'll never have a problem.

      I'm pretty much healed up post surgery so I spent another almost full day out in the shed re-arranging everything to make room for all of the shit that I've taken off the car.  I need to get everything off the floor and away from the car for when I start making a massive mess stripping off the remaining body deadener and then for the the painting process.  Almost got the shed to a point now where I feel I can actually start working on the car again (clean shed clean mind or something!).  Almost 11 years of accumulated car parts, building supplies, tools, junk, etc have taken a long time to get in some sort of order again!  Most stuff is now boxed up and in the back shed if it's not car related.  Most people would still be horrified walking into my shed but it's significantly better than it was before!   For those that saw my separate post the other day, yeah I ordered one.... This version- I convinced myself to stop being a clown, wake up to yourself and realise it will take you 5 weeks to make one by which stage you're over working on the car again...  Maybe I am getting on top of my "mental ailments" and making smarter choices.... $1450 delivered which will take my miserable half-dutch arse a few days to get over having spent that much!  If I don't have a use for it straight away after my car is off it I might even see if there is a "rental market" for them.  See if anyone wants to hire it for a period of time.  $25 a week or something like that.  I'll worry about that when my car is actually ready to come off it though as that might be a while away!! There's now no excuses now for not ending up with an underside you could eat off! Away for kids sport the next few weekends so hopefully can get the rotisserie assembled ready to go for the car to go straight on it the next available weekend.
