Hey guys, I run a set of the yellow jacket coil packs that Performance Wise offers. To set the scene, picture an RB30 block, built to "nissan spec" (Now, I use this term loosely, as the whole motor

Not true for Yellow Jackets. We tested the YJs thoroughly before releasing them to the market. Not just in the factory, but on the street and the track, in real life circumstances. Im still in contact

This is an outdated statement as everything is made in China these days. My Yellow Jackets are made in china and I oversee QC and work closely with my factory and now, 5 years later, and over 2000 se

coils are coils, but you would need to stuff around mounting them, they would not have bolt in direct fire ones like jjr/splitfire/owm

coils are denfinately not all the same. the aftermarket stuff has really come a long way. the nissan std coils r quite good, but imo there is a whole range on very powerful coils out there that would b better than std (and prob cost around the same sort of $$). example, i changed to MSD coils from stock ones in my V6 commodore and dropped from 14.5 to 14.02 with just the coils and a small adjustment to the tune in the last 1000rpm (merely to correct a/f ratio). making brackets isnt that envoled either.

Well i have some issues with Splitfires, the first set died 6 montch after purchase 4 coils startred to die, and it looks like that migh be the case again, either way my Central 20 ECU and splitfires don't like a gap above .8 mm at 15 psi

The issue is clearly with the ecu/tuner combination.

Have your tuner pull his finger out of his bottom and check the coils dwell vs rpm has been setup correctly.

If its not it will either provide a weak spark or overheat and kill the coils quickly.

My bets are on the later.

does that mean if i put aftermarket coilpacks in i will have to get a re tune. you cant just put these in?

are you sure your central 20 ecu supports sequential ingition and is not operating in batch mode or something ?

out of the 50-60 or so splitfires we have supplied in the last 12 months or so we have NEVER had a single one fail

out of interest OEM coils are 180 each trade price and the coil pack loom (engine sub harness) is about 200$

standard ecu

mods - zorst, FMIC, pod

only mod i added since splitfires was manual boost controller set to 10psi, 200rwkw

and i don't thrash my car, only done 5000km since coils changed to the splitfires

ok as you didn't fit the splitfires your self I'm assuming your guessing that the coil packs have died.

In other words you haven't pulled the coil packs out yourself, inspected them did the usual trouble shooting one does before they come to the conclusion that something has died. :ermm:

What brought you to that conclusion?

If its started popping it can be maaaaaaaaaany things. :D

The AFR's are too rich.

Plugs need regapping.

Plugs need replacing.

Ignition has crapped its self (if its a s1).

So fingers crossed its something silly. :D

yes i am guessing so probably shouldn't assume :D

but the car makes excatly the same noise as when my OEM coils had died.

last week it started stuttering/shaking at idle. now at 4000rpm onwards it pops to the bs

took it to my other local mechanic and he had a quick check of the plugs/sensors/af meter couldn't find anything obviously wrong

plugs were replaced same time as splitfires installed

don't have an a/f ratio gauge

yes, hope hope it's something basic. otherwise hope hope it's still covered under warranty. i've still got the receipt from the mechanic.

anyone know what the warranty is on splitfires, someone please say 12 months?

found these coil packs on ebay. they are called super spark coils and they say that they give you 10% more spark and they are to suit RB20, RB25 and RB26. at $499 what do you reckon? has anyone else heard or know of anyone using these.

they look to me to be similar looking to the JJR packs

They are exactly the same as JJR, only $100 dearer per set.

      Let's hope that's not a copy pump either. There were so many copies of them back in the day.

      Damn it, I was at work last night, and stayed in a room there during the storm with the car outside, but undercover, I just went downstairs and well....there was a large steel locker that has come from some place last night, it wasn't anywhere I could see yesterday, and yeap, it landed on the fraking car....of course it did..... LOL So, I'll need to take it back for paint and panel, luckily it was only the boot that took the hit, so it could have been worse Serves me right for staying at work and getting on the cans with some of the boys

      Yeah, really happy with how it all turned out As for aftermarket lip, nah, I'm not really a fan for practically reasons on a street car that gets driven everywhere  I did have the full lower kit on my 2015 STI, but found the front lip scrapped alot, even at stock 4x4ish ride height As the NC sits now, with the lowest point of the car at 110mm, so just legal, some steep driveways and steep speed humps will still "just" scrap those little plastic OEM air dam thingies on the undertray just before the front wheels

      Here's one I help build and tuned a decade ago, Garrett  GTX3071R Gen 1, T3 twin scroll 0.83 rear housing. Went from larger 272 cams down to smaller Tomei Poncams to help with the low end. S13 non VCT motor. Car was purpose built for the track, hence low down was the focus. Note the actual dyno chart shows lower boost, however the EBC and boost gauge showed 1.9Bar (Ignore the torque, I was young and didn't know how to set derived torque)

      Hypergear Turbochargers and High flow Services Development thread

      I’m doing some side developments on SR20det S13 engines, its one my hobby cars used it to compare flow capacity of some smaller size wheels. SR20det is one of another JDM legendary engines I'm sure there are plenty of SR enthusiasts on this forum, I will share results some common turbo configurations here. a quick run down of what the car is: Wide body 180sx Type X with black top engine (blue). It has: Stock bottom end Haltech 1500 ECU 5-0 motorsports trigger kit Kelford SR20DET Beehive Spring with Titanium Retainers Kelford Cams SR20DET S13 188-B 268/272 Cams G25-660 Turbocharger in T2 .64 rear housing internally gated ARP Head studs MLS head gasket 1000CC ID injectors Walbro 450L Fuel pump Front mount cooler kit JJR’s 3 inches turbo back exhaust (its too short for the 180sx it had to be extended) Pump 98 fuel Hub Dyno tune So far made 270rwkws at 22psi full boost by 4500RPM. Engine is very knock limited hence a pretty bad looking top end. From previous experiences it seems like SR20dets are happier with bigger size turbine, some thing like a GT30 would make way better top end, but on same time response is lost. It won't be a problem with S15 VCT engines. I'll be testing alternative turbine housing, turbine wheel and possibly dump pipe options for extra flow to resolve the problem and of course E85 would resolve all the issues.
