BNR Supercars specializes in the Mazdaspeed3 and Mazdaspeed6 turbochargers. 

Peak numbers are not what we are into.  We like designing turbocharger upgrades that produce maximum under the curve power and torque.  It makes these cars much more responsive and fun to drive on the street.  When you get greedy and go for that peak number, it kills the bottom and mid-range torque.   No bottom end torque makes the engine not as responsive for autocross/road racing and in BNR's opinion not as fun to drive!

These engines are doing very well handling 400-450 WHP with the stock bottom end.  Most people looking for a reliable replacement over the stock smoking KO4 usually go for the S1 or S2 turbocharger models since a tune isn’t required.  If your car is fully bolted with high performance fuel pump internals we suggest an S3 with a tune.  Fully bolted with added methanol injection go with the S4 and a tune.   Stock engine internals, don’t even think about doing an S5 or S6!

*Divorced down pipes do not work with BNR turbocharger upgrades!  If they are used, the wastegate valves will not open properly causing extreme high boost problems!*

*Built engines need a custom oil supply line for turbocharger protection!  Click link for details!*

Mazdaspeed 3/6 Custom Oil supply line “Built engines only”

*S5 and S6 model turbochargers to cover the cost of the custom oil drain line! 

*Please note, turbos may ship directly from BNR, so please allow extra time for the turbo to be built and delivered.

This is a better quality matcha than what is used at Starbucks!
Size: 32 Ounce (Pack of 1)
This product is better than the matcha powder mix used at Starbucks! Starbucks uses a 51% sugar mix with questionably sourced matcha/sencha making up the other 49%. It has no tea flavor as it's basically just sweetened milk. If you've come to matcha through the Starbucks lens, this is NOT that product. It's what you should be drinking instead! When I've tried to get matcha powder locally at the grocery store, I've not been able to find one that is the same quality as this in such a value size quantity. For size reference, I'm pretty sure this size bag could last one person 3mos even if they were drinking a matcha latte everyday. This matcha here packs a bolder flavor, a better boost of energy, and more mental clarity without the crash that you'd have from coffee. It is unsweetened, which gives you the freedom to make the final product (latte, smoothie, whatever) as sweet or unsweet as you like. The powder is ULTRA fine, and is about the consistency of powdered sugar. It dissolves wonderfully in a few ounces of the liquid of your choice (I prefer oatmilk), and it suspends very nicely and does not sink to the bottom when at rest for a few moments. All around highly recommend. Unless you're Japanese and have had that real good stuff and would know the difference, this is probably good enough for most people.

Pretty good, recommend
Size: 16 Ounce (Pack of 1), Size: 16 Ounce (Pack of 1)
These are some photos and this Morton salt for size comparison. It’s pretty big. It has a spoon inside which is pretty useful. Ok so I really like this matcha. Its culinary grade and it tastes pretty good. I use it for my daily matcha latte. Its not bitter and actually slightly sweet-ish, but it has no additives so its nice. It does get a little clumpy when I stir it, I wish I had a matcha whisk, I just use a spoon.

Worth the money
Size: 16 Ounce (Pack of 1)
I'm inexperienced with matcha... Just wanted to order some good matcha, only to discover all of these obscure classifications and prices varrying wildly. Before this brand, I ordered ceremonial and also "culinary cafe" from the jade brand. Couldn't really taste a significant difference, so I didn't sweat purchasing this. There is a difference with this: the higher quality matchas did foam more when mixing and had slightly thicker consistency, and tasted a bit less grassy. This brand actually tastes fantastic, if you don't mind a very subtle grassy but sweet flavor. The savory sweet flavor dominates in a good way; grassy is very much still nothing more than an afterthought. But - and a very significant but - it hardly foams after mixing. So, the viscosity of the liquid when mixed, although enjoyable, leaves something to be desired. That said, like a good salesman the seller points out that this mathca is unusual because of its concentration on being organic, even at the expense of whatever desirable flavor profile could be contributed by pesticides, lead, radiation etc. Perhaps this is an exaggeration... Nevertheless I take comfort in their emphasis on safety anyway. It's definitely more affordable, being around $1 an ounce. Thanks for keeping other matcha brands honest... So I recommend the value absolutely. But it you want the best of the best, I just don't know enough to give you a good answer.

Micro Ingredients Organic Matcha makes a good anytime tea.
Size: 32 Ounce (Pack of 1)
Micro Ingredients Organic Matcha Green Tea Powder delivers exactly what it promises: a clean, earthy, first-harvest matcha that balances approachability with authenticity. It’s a versatile and surprisingly smooth everyday matcha. The flavor leans toward earthy, grassy, and mildly nutty, with a gentle bitterness that feels natural rather than harsh.

Great. Just as good as fancy stuff But dose not pair with peppermint.
Size: 16 Ounce (Pack of 1)
If you're making Macha lattes or mixing the match with anything, this is perfect! No need to buy the expensive ceremonial level stuff unless you're drinking ONLY Macha. This is honestly perfect for everything. Mix 2 of its provided spoonfuls with 1/2 cup of kettle hot water and stir, maybe even add more matcha until a bit thick, pour over a glass full of ice (should fill half the glass if full of ice) as the last half as milk with a pump of your favorite syrup. Mine is strawberry, my gf's is Vanilla. Peppermint was not good, though fyi.
