I did use the search function but all I found is built thread with people saying they have a DLI installed lol..

I bought a HKS DLI with the idea to buy a brand new set of coilpack to replace my 20yr old oem coilpacks. I know OEM coilpacks can be good up to 800whp. ( If I break the 500whp I will call it a day lol). I also know that brand new coilpacks can give you an extra 3-6whp.

1) Can coilpacks, after times ( in my case 20 yr old lol), becomes less efficient? Would a HKS twin power boost the spark and make them act like brand new coils?

2) Can I really see a gain if I get brand new OEM coils + the HKS DLI ? Or I'm better with only a new set?

If both situation get the same result, I rather buy a set of coilpack then keep old coilpacks and add an extra metal box in my motor.

Is it wise to change the coilpack loom while I'm there too?

Personally, I'd buy a new set of OEM coils and install the HKS DLI if I have any spark issues (ensure your gaps and heat range are correct) but 500whp is pretty stable for new OEM coils. If you have it though, you could always install it I guess.

As for your ignition harness, if it's crispy or you have some connectors that are starting to break, I have one with less than 1,000km on it, bought last year. Shipping from someone close ;)

I had my stock coil packs start to break down over 20psi (370ish rwkw)....while using the Twin spark. Went and bought a new set of stock coils and all good.

Personally in your case I would buy a new set of coils.... and if you still have issues then chuck a twin spark at it.

This exactly.

You've purchased stuff backwards.

Replace the coils first, if issues persist then use the DLI

instead of paying well over $1k for an OEM coil pack, get a set of spitfires.

I run Spitfire coils and a HKS TwinSpark. No spark issues. @ 620hp atw.

we tested brand new oem vs splitfires and found we could run more boost with the oem ones.. even SR20 ones.

New oem ones are now cheaper than splitfires....

ATM the coil packs average $55usd each brand new...

that,s the thing.. At my local dealer, they sell 6 coilpacks for 300$ tax included LOLLLLL 2x cheaper than spitfire or 150$ less than yellowjacket.

and my friend needed money quick and sold me his twin power for least than half the MSRP. I couldn't say no. Worst case, I will simply sell it back.

Very good point... OEM are great but when they are 10-20 years old they need replacing!

I was unaware you could get them that cheap now days, last time I looked they were about $200 each :(

lol when did that happen? i remember buying my splitfires cause they were cheaper than new OEM's (and JDM tyte y0)

locally you can't get them that cheap, Nissan Aus i don't believe have altered pricing.

For some odd reason, Nissan US have some items much cheaper in some instances.

Yeah all my parts now come from the US, generally 5 day from order to door.

Sux i know not to support local business but if its half price in another country including freight then im sorry... your not competitive.

Just get onto a supplier, some stuff is cheaper - some stuff just isn't.

NFI what governs pricing, but its likely as a GTR was sold here (32) they are putting it up.

They weren't locally delivered there so perhaps not so much profiteering going on.

I mean just for a CAS, there is a $400 "Nissan" markup over what Mitsu charge them for it

I upgraded to LS2 Truck Coil Packs. No more ignition problems and they outperform the others.

just makes for an untidy engine bay and introduces plug leads into the equation which is another point of failure. Put new oem coilpacks in and ignore them for another 10 years :P

    • Have a vb in honour of the car comming back
    • It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪
    • And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil
    • Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.
