I'd be interested to know this too.

Installation complete! The instructions were well written, but there seem to be some minor differences with the S2. There is a wire bundle that makes it extremely difficult to plug the wires into the coils. It runs right along all four coils right where the wires plug in, it took some effort to keep the bundle out of the way while plugging the wires in. Plugs went smoothly once the wheel was pulled.

Results seem promising, only drove long enough to warm her up. Idle seems a bit smoother. we'll see in a couple days.

Deminic do you know what gas mileage you were getting before the swap? Also did you change your plugs wehn you swapped the coils in, by your post I think you did but just wanna check.

I'm at almost 25k miles and have been thinking I need to change my plugs soon, if you did change them how did yours look?

Definitely change your plugs, yes we know that they are meant to last a lot longer and they do, BUT, they do not perform at max capacity, IMO , I did mine at 20K (12K miles) and noticed a difference once renewed.

At 12k (miles) my plugs were close to the recommended Max Gap limit, which for memory is 1.4-1.5mm...there is a slight difference in Min/Max electrode to earth plug gap for leading and trailing plugs, I would have to fish info out from my other PC if you want exact numbers.
But YES, mine probably would have lasted much longer,,,BUT..

IMO new plugs are a better investment for S2's and ANY rotary.

Deminic

Car has just over 30k mi.
All driving is mixed City/HWY and am relatively heavy footed. I get 15-16mpg on E10 and 18-19mpg on E0, both premium 91 or 92.

Its quite obvious that on the coil that the white ring is arching through the coil. All 4 coils are identical.

The plugs show signs of a healthy (using piston standards for color and wear) engine, but were in need of being replaced.

Deminic

Update:
I have gotten a couple of refuels now and it seems that the E10 efficiency has improved marginally, but the E0 efficiency has maintained.
Power/TQ: did not have a noticeable change, not that one was expected.
I can however, report that it does idle smoother and start easier.

I sadly have not been able to a dyno and don't foresee being able to do so in the near future.

Deminic, any significant updates on this?

Deminic

Not really. Couple thousand miles, holding steady. Nothing noticed while on the autoX track.

After a year of sitting on the fence I have finally placed an order for the BHR ignition system for my 09 VR GT :D

usiris208

So I just read a little about this and was wondering if I don't ever take my r3 to the track is this still a good 1st upgrade for a daily driver?

my personal opinion (may or may not be shared by others), although it will be beneficial in teh long run, it isn't necessary as a first upgrade. How many miles are on your car? I only have 11k and have had no starting issues, no major fuel consumption changes, smooth powerband to redline. If you have a significant amount of miles (i would say about >20-25k) then I would surely look into it.

usiris208

Yea i have about 30.5k on the car. Since I'm not too tech savvy with cars and don't know how to do most things... But if I buy this would it be better if I take it to a shop that has more knowledge on rotary engines or is it simple enough for any mechanic to do?

xexok

Yea I don't think its a thing that needs to be done right away. I wish I could have afforded the BHR coils recently when I changed mine because it works out to be a good deal eventually. Oem coils + wires are around $250-ish to change each time if you do all 4 coils, or just buy the BHR kit once for $500 and never have to worry about it. If you plan on owning your car through at least 2 coil/wire changes then it makes sense to try to get the BHR kit.


It is pretty simple to install. At 30k miles you should seriously consider replacing your coils/wires/plugs soon. If you take it to a mechanic then it is going to be pricey.

Honestly it is one heck of an easy mod ... as long as you know how to remove a few screws you can do it no problem. Either way, it is a standard job and can be done by anyone regardless on if they are a rotary mechanic or not. The only real way anyone ever "screwed up" was putting the sparkplug wires on the wrong coils, which would just make the motor run like *** and you will know immediately. There are some DIY's on it, check em out, you will be surprised on how easy it is.

usiris208

Thx...will definitely check this out.

Where have u been? U know it cost less than 150 bux for coils and wires and it has lifetime warranty right?

xexok

I wanted the OEM coils, not some random Chinese company that just decided to make them. Yes I could have bought wires for $22 from RockAuto and coils for cheaper there or somewhere else. Also everytime people try and tell me they have "lifetime warranty" on their coils I check and its like a 2 year limited warranty.

I just wanted to give a little support to the rx-8 community by buying some items from companys/people that try to help us out. Nothing wrong with spending a few extra $$$ to help out so those people stay in business.

again, where have u been? i got them and its made in japan. only place that 2 yr warranty is autozone which is not the place i was talking about. mine is lifetime warranty. the store i bought them from have them now and yea, its still lifetime warranty.

And whats wrong with buying ngk wires for 25 bux? its just oe wires and u can get it at amazon

Nothing wrong with supporting bhr, they are good guys. but for most people, stock is just fine especially when it has lifetime warranty

usiris208

Ok so now I hear you guys talking about other companies. So my new question is... Is there a major difference between bhr wires and others like ngk that was mentioned above?

Ngk is just oe wires without mazda box at 1/2 price

Im sure bhr use higher quality wires but if you are not into every single bit of performance, oe or ngk wires work just fine. Mind you. You dont need to replace your wires with the coils or 30k miles. Replace them at 60k to be safe. Or just replace them if its showing any signs of wear. Which is usually more than 80k miles.

Speaking of coils maunfacture, xerox mention like about china crap, mazda dont make them, they got them from some other oem, probably nippo denso. And after a few years they will be allowed to sell them off wihout going thru mazda, and to lower manufacture cost, you go to places with lower labor cost. As long as it has the same kind of requirements, does it matter if its made by chinese or made by japanese? Are you trying to tell me that the coils will magically last longer if it was assembled by a pair of japanese hands? You do know who made all those wonderful iphone/pad/whatever that the american press calls it the most revolutionary product, right? Oh yes you should heard of Prada. They call their products made in Italy, but they got busted cuz its actually all made in china, then they just ship it back to Italy and put that made in Italy tag on. Not all made in china stuff are good. There are crappy ones. But again if it meet certain requirements, i really dont see anything wrong with it.

Prophet

There is a reason people don't like Chinese made products. Aside from political reasons, the standards of manufacturing are far lower. That's why we had kids toys with lead paint on the market. They do not care. Most OEM knock-off parts from China tend to be pretty shotty. I have seen hard parts like A-arms from China made from much softer metals that bend or break very easy compared to OEM. There is reason they are so damn cheap and it's not just the labor cost. Some high profile products are good, because of heavy oversight by the contracting company, like your apple example. Things like car parts are not protected like that. Do what you want, but I avoid Chinese crap as much as I can.

xexok

I dunno I don't purchase apple products, believe it or not I have never owned an ipod. There is just a reputation for chinese goods to be cheap and not work as good. Is it true? Who knows for sure, some china brands are horrible and should not be made while I'm sure other things work fine.

Btw my wires looked pretty shitty at 30k miles, some parts of them were starting to look heat damaged. It might be a good idea to at least inspect wires at 30k. I know I could have got OEM NGK wires from RockAuyto cheaper but I went for an "upgraded" which I am not even sure is an upgrade. The BHR wires probably do nothing but at the very least they look better on the engine. :P

You just have to know what u r looking for. There are garbage brands everywhere, china has more simply bcuz most ppl ask for the lowest price tag. While thats a normal thing but after certain point, u just have to make compromises. But ppl never blame themselves for their ridiculous request in the first place, but they just love to bitch at the manufacture.

Lead posion toys, i guess u forgot that we got that in the states too when we were still a delveloping nation. Even today lleaded paint is still everywhere in nyc. They shouldnt do it of course, but see the reasons above. We had that problem too, and ittooka while for us to correct them, and its still affecting us today.

Me neither, i never had any apple products. But they are all made in china and theyhave pretty bad working cindition, explains why some of them choose to end their life.

I stillhave my oe wires, i swap them out b4 to try rb wires, and now im back to oe wires, cuz really i dont see much point to use fancy wires at stock power level. Wanna dress the engine bay up with that red wire? Sure. But im cool with the ngk blue in my engine bay :-)

ASH8

ain't that the truth

xexok

I was talking about the wires I bought from you guys that fit the regular coils, I don't think they really do much for me other than look nice. Not saying anything bad about the wires, they look like they will at least last longer than oem.

xexok

I feel like we are having two different conversations here, and I have no idea what one your having.
