No Splitfires have the track record that the OEM ones do. I have new OEM in my car - been running them at 1.5 bar for three years and expect they will continue to perform since my first set lasted 15 years.

That's not even the correct argument. Why risk buying yellow jackets at all, despite the warm fuzzies of forum trader and all that stuff, when they have a higher number of failures than Splitfires and don't save you much money anyway? I'd rather pay the extra and suffer the tiny failure rate of Splitfires than save 30% and near 1 in 3 failure rate that I've seen with yellows.

Couldn't agree more.

Mine and a few other members from here and HT have had Yellow Jackets literally melt. No refund given, only an ear full. A dodgy product is a dodgy product and should not be endorsed when it can cause major problems. This was with only 11psi and 1.1 & 0.8 gap me personally.

Now using splitfires on 13psi and they work fine. Have heard of a few people having problem with them, but it's quickly sorted and they've been sent replacements.

If i had my time again, I would have just bought OEM as bob said, they lasted 15+ years.

Was told its original, looks original quality wise and hasnt missed a beat 22psi for 7 months- lets see how it holds. And got it under $300 delivered. Screw YJs---never ever again theyre rubbish.

Under the artificial limitation that I cannot spend more than $500 I would clean up my existing coils and/or buy some 2nd hand originals until such time as I had the money to buy Splitfires or new genuine coils.

Face it. $500 is co close to the price for Splitfires or genuine that the gap is almost meaningless.

Let's put it another way.....would you buy a known non-genuine Z32 AFM for, let's say, $100, given the knowledge that they do work and have been used by a number of people, or would you rather pay $200 for a known genuine one? The other part of that question is that the known non-genuine ones, whilst they work, don't have the capacity that the proper ones do, and therefore can't be treated as if they actually were a proper Z32 (ie you can't use the Z32 curve in PFC or Nistune). I see the Yellowjackets thing in the same way. They work, but they don't work well enough and reliably enough to justify the relatively small saving in purchase cost.

I went through two sets of "good" second hand OEM coils before getting Yellow Jackets.

If my car was my daily, and I had the choice of running YJ for $400 or OEM for $800+, I'd go YJ because 1. my car is standard, 2. I can get the YJ in a couple of days, whereas who knows when the OEM ones would come. If I was running 20psi on a build motor, I wouldn't even consider anything less than OEM. Like I said, my set has been flawless for 2 years daily driving + two track days, yet people have had bad experiences with them almost instantly. It is what it is, a cheap alternative. People had good results with them as well, obviously not on high output motors.

I'm not saying YJ are better than X (I'm not affiliated with them, not endorsing them), what I'm trying to do is give audience of this thread (a public forum) a view from a non-built-motor perspective. People with faulty YJ coils had good replacement experiences as well.

This post is for the poor/tight arses who are looking to spend minimal but have something that'll (hopefully) last a bit longer than something even cheaper. But these days OEM is a lot cheaper, so if I were to buy a set now, I'd get OEM.

If that is legit original, then great buy! I'm guessing seller got it from UAE? Wonder why they're $50 from there, but $100+ from Japan.

How do you know they are original? seems too cheap for anyone to make a profit from that sale

Splitfires I would think would be better than OEM, when you see 1000hp GTR's i don't remember them using OEM, usually theres a set of splitfires, for example the

Mercury Motorsport 34GTR uses Splitfires and that's what was recommended to me.

To me the only way to ensure you are getting genuine anything is buy from a reputable source.

I seriously doubt the coils you bought are genuine. There are fakes going around.

I'm glad they seem to be working for you.

I don't think it matters whether you're talking OEM or Splitfire when it comes to severe duty applications (your 1000HP engine situations). Those coils are just not up to the task and you'd always be considering a conversion to GM truck coils or some similar solution these days anyway. Can be done for $800 or so easily enough these days.

Bought new original coils several years ago. Factory boxes with all the right printing. Very professional. Lasted 3 months before severe breakdown. Bought Splitfires and been good for a year or so. Revs clean every time. There are fakes but the price will tell you that. Buy from Nissan and get raped on price. So that leaves Splitfires.

I've had my YJ's in my GTR for 2 years now, 332kw on 21psi and can't fault them so far. In saying that the car isn't a daily driver so not that many kms on them.

Car will be off the road for a rebuild now tho due to suspected 6th ring land failure. Good times

Yeah those are the newer ones - the older ones (before they had a printed serial on them) were a atrocity - I had 3x let go on me and because they were out of warranty I wasn't covered but Paul from PW ended up selling me replacement ones for $60 delivered.

However even with the new ones.. I had spark blowout at 1.3 bar at 0.8mm gap.. if I ran a smaller gap it would work but who wants that?

Now I run Splitfires at 1.5bar and 0.8mm gap - happy days.

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
