R35 GTR coils on the older Skylines with an RB26, with a replacement coil loom to run them so plug and play job! They are OEM Nissan so no issues with cheap Chinese fakes!

found another variation of the VAG Coils done by Ignition Projects , its basically Porsche Cayenne Turbo coils . Don't know how these Cayenne Turbo Coils vs R8 Coils vs LS2 Coils in firing power. It would be nice if someone can do some extensive testing on these. Seems like the biggest advantage using the LS2 Coils is sits much lower than the VAG Coils.

Why you need lower coils? I have vag coils and plug cover sits nice to its place.

Hey guys digging this back up.. AGIAN ( im GTSr32 reincarnated forgot my old email address)

Can we confirm the standard Dwell Time for the Rb coils? (phase 1)

R8 coils 06E905115E or NGK 48041 suggest to like around 2.5-3.0MS and can go up to 3.5MS but 3.5 can cause problems

Oem and splitfires are between 1.8-2.2 ms @14v.

So when people start coming up with new coils from every car known to man then one must make sure the dwell times are adjusted for the new coil setup.

Find that the Non R8 coil or the TSFI coil looks closer to the OEM Dwell time!


0221604115 "long" TFSI

charge time (Dwell) -> 1,8ms @ 14V (15 Ampere)

energy (1000V zener load) 55mJ

pinout 1: +12V (switched)
2: ECU ground
3: signal (TTL)
4: engine ground
---------------------------------------------------

add 0,2-0,3ms charge time for wiring resistance (0,1 Ohm)

Also

Can someone tell me what Voltage and Amps run to the coils?

Hi everyone.

I'm running the NGK 48051 since April.
I was sick of misfires out of the blue with the Splitfires i ran before.
Got a new Coil Harness, tried a different ignitor, plugs, added grounds, lowered the coil mounts 2mm to make up for the 3mm shorter plugs, NGK Iridium BKR8EIX, compared to Japanese Spec Plugs.
Nothing helped.

So i made my own wiring harness to fit the NGK Coils.
Running power straight from the battery over a relay, triggered by the power source of the stock coils.
Used 4mm^2 to the relay, 2.5mm^2 from the relay to the coils. 2.5mm^2 for ground as well and 1.5mm^2 for signal.

It sure takes some work but it was mad worth it. The engine runs a lot smoother and i haven't experienced a misfire since, not even exceeding 2 Bar going into boost.

I did have to adjust Timing a little as i had a little higher knock Level around 6500rpm, may have been an issue due to quicker/stronger spark?

I honestly am really pleased with this ignitoin setup and even if a coil burns out, who cares!
A new one is less than 30***8364; shipped to my door. Probably the best ~250***8364; i've spend on that car so far.

Setup:
Built rb26, PowerFC, Borg Warner S366 Single Turbo, 666hp/850Nm @ 1.7bar.

EDIT:
FYI, from what i know, the only VAG Coils that are actually lasting are supposedly the NGK 48051, the short versions as well as other manufactors than NGK are known to go quickly.

NGK part number & pugs/sockets

I am interested in doing this conversion, but having looked up the NGK part number you have quoted NGK 48051 it appears to be a rail with 4 coil packs mounted on it.

Did you mean NGK 48015 which is a single plug mount coil pack, also where did you source the connectors that fit onto the coil packs i don't know if you would call them plugs or sockets.

any info or clarification would be appreciated

Try again mate. I just searched and it came up with a pencil coil.

Ok so a quick question about working out the required dwell. Would you have to factor in for any delay the old ignition amp also?

Bit of a con those IP/Okada kits, lots of colourful words and pseudoscience spin. they compare there Porsche Cayenne coil to an "oem" one whereby they overcharge (overflux) to 13 odd amps whereas the other one plateaus at 7 odd amps (inbuilt current limiter) you can see the dogleg (saturation point) on the IP plot occurs when the other one goes horizontal.

The speed hunter guy must have got them free
Stay OEM !!! save your money

Absolutely my thought on them also. They take stock coils as indicated by their R35 versions. Pics below show stock and an Okada coils. See markings and their red embossed logo/cap what ever you want to call it.

Not the first person to say speedhunter gets all his parts free. I heard he does get everything free to then review and give them coverage in their magazine. So parts mentioned and reviewed you got to be careful and do your own research so not to fall for their bias.

Soo what sort of power or boost levels are people maxxing out on the standard/upgraded rb26 coil packs?, or is this more of a reliability mod?

I currently have these. Recommended by a friend but from what I hear, you can't run the center plate when you have the R8 coils installed? So I might send them back at this point. I was planning on running the center plate.

Never seen them with a centre plate they appear push on.

You could always go for the R35 setup.
