BNR S5 Turbocharger Upgrade

The S5 has a 3.5” compressor inlet and works with a 3.5” or larger intake pipe (same casting as S4).   All the tuners like using an aftermarket boost control going to your 44-46mm v band style wastegate!  The S5’s point milled, billet compressor wheel is rated for 62 lb/min air flow and is the larger of the 76mm Garrett compressor wheels with a 58mm inducer and 76mm exducer with 3mm compressor tip height extension.  Our S5 is comparable to the competition’s GTX 3076, but what separates BNR from the others is our own custom, 44-46mm external wastegate, .82 a/r turbine housing!  This turbocharger on a forged engine with ported stock intake gets 20 psi by 3400-3600 RPM.  The first test car maxed out the intake and the 6 port injection at 515 RWHP at 32 psi!   Axillary port injection is needed to go higher than stock fuel limitation  (370 WHP).  The S5 has the capabilities for 550 WHP without sacrificing response.  The S5 spools better than the competition’s 3076 by approximately 300 RPM even with the big turbine housing!    We lowered the price recently because we stopped making the oil return lines!  OIL LINE DETAILS HERE!

Here is what you get with the S5 turbocharger upgrade!

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.

Has no oily scent.
Scent: Earthy, Nutty, Refreshing, Size: 4.06 Fl Oz (Pack of 1)
Just started using it. Smells like oil not over powering. The quality is rich and it’s not runny oily. For the size of it’ll last couple months. Worth the price.

Pattern Name: 8 Exfoliating Gloves, Pattern Name: 8 Exfoliating Gloves
These are a absolutely excellent pair of gloves and I am very impressed with them. They are a great price for the quantity and quality of the gloves. I have used exfoliating gloves before but they were extremely cheap and of poor quality coming from China and I was never very impressed. These gloves are of another caliber entirely. They feel nice to the touch, aren't scratchy or irritating to be worn on your hand while your exfoliating with them. Some other gloves or exfoliating stones are abrasive and when you are done they leave your skin raw and irritated but these ones did not do that, they gently rubbed dead skin off and I could actually see it coming off in tiny little peices and when I was done my skin was so soft and clean afterwards and I have never had any exfoliating product do that before. I bought some sun laboratiories exfoliating body gel once before and I used it with these gloves and it worked fantastically as well.

I am in love with this mitt
Pattern Name: 1 Exfoliation Glove, Pattern Name: 1 Exfoliation Glove
I am in love with this mitt!!! I am a long time user of the sun laboratories sunnless tanning lotion line of products and I use them all the time to give myself a wonderful golden bronze looking tan and generally it comes off easily with soap and water but sometimes it doesn't come off as well and I still look a different color than what I actually am. So I came across this mitt when I was looking online to buy more of the sunnless tanning lotion that I always use and it was reccomended that I try this out. I bought it thinking that this could be what I need to help my skin look better and I was not disappointed when I used this. It gently rubbed all the sunnless tanner lotion off and my skin looked back to normal, there was a major difference in my skin tone from before and after I used it. This mitt also works if you use the sunnless tanning lotion repeatedly for several days or weeks in a row and don't have time to properly exfoliate to get it all off in between each time that you use the sunnless tanning lotion. It easily rubbs off all the built up layers than can get gross and make your skin look off.

Works great!
Pattern Name: 1 Exfoliation Glove
This mit works great! I used a tanning lotion and as it started to rub off I needed something to help make my skin even again. The shower water was brown as the water rinsed my skin and the mit. So I know it was working! It is a little rough on your skin to hell scratch it off but overall I recommend.
