Your kidding right? If you cant see that they are fakes then I question your integrity.

The guy has even copied the vehicle compatibility list from my own listings.

Do it Tao, will be a good test 30 psi and massive cylinder pressures we subject your car to week in week out.

I need to build a huge turbo to do that. Aiming for 500rwkws this time :P ?

They are good quality. See here for some feedback from real people who actually use these.

Thanks but all testing was successfully completed for most of these coils a few years ago.

I've had a set of those not in your brand. and they only lasted two dyno pulls on about 18psi of boost. My car is a built test rig, I test all sort of turbos on it and gets dynoed ever week. The level of testing is far more serious then some one looking for abit of extra power or whom ever initially trailed yours.

I now us split fires, they gets 30psi through them occasionally and they are pretty good, so if I trail yours and they work then you know they are as good as some branded items, and I'll be happy to pay for them and use it on my daily R33.

If they fail then you know more R&D is required so hopefully you can come up with a better product in near future.

Status - u do that. As for me. Im over it and I wont respond here anymore as its unfair to the thread owner. I suppose we will resume this argument in another couple of years though.

Maybe after 10 years you might accept my product as worthy......probably not :rolleyes:

HyperGear - I would like to see your results but Im not offering free samples sorry.

No no not free. I will return them to you after testing. Or I will pay for them if I wish to keep them.

you have to admit, to the untrained nose, it really stinks in here.

ive been using yellow jackets since performance-wise first started selling them.

they replaced the oem set that were breaking down.

i dont claim to run a test rig, and i dont run 30psi, but then again, how many do?

daily they see 15psi. ive had them on a mates car for a day, when his splitfires! were giving him grief. the YJ's ran 19psi with no issue. so he promptly ordered a set, and hasn't looked back.

and if that isnt enough to convince me, the service from performance-wise is outstanding. ask anyone that has dealt with him.

there are countless stories of stupid fast warranty replacements, etc. i havent needed to go down that path, but i know if i did, i'd be glad i'm dealing with him.

meanwhile, there are sponsors on this forum, praised to the shit house for fk knows why, (i refuse to name names), that can't manage to sell you 3 parts without fking the order up, and have in their product line, some of the worst chinese junk you can buy (coil packs included).

10/10 for my experience with performance-wise & yellow jackets.

THIS +1TY.

The bottom line is: YJ's are a good, price competitive product for everyday use for the majority of skyline owners that aren't running 14bar of boost. if the YJ's can't handle 30psi of boost..so what? The guys that have spent thousands preping their cars for the extra can fork out another few hundred and upgrade their ignition systems.

I replaced a set of splitfires with YJ's ~2years ago. Done ~2000kms in that time running 12psi and no problems here. Sometime in the next month i'll be seeing how they hold up to 24psi+.

I agree that they are good for street driving moderate power and boost applications to replace stock flogged out 20+ year old OEM items.

But to say they are on par with OEM or Splitfires when pushed is incorrect. Going past 20psi on my old Green Gts-t we had to start exponentially decreasing the plug gap so that the motor didn't misfire.

you mean to say there is a minority running 14 bar of boost :woot:

      Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL

      Jacks that fit under GTR lips that can reach the subframe?

      By joshuaho96 · Posted

      On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.

      Mistakes were made, my R34 Story

      Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
