Miata MX5 2016-2018 · Engine


Max YOUR ND Miata Performance!  Each of our ND has over 200 runs on the dyno to test everything from headers to intakes (the headers work, intakes really don't) to superchargers and turbos.  It must be noted that the ND has the smartest ECU we have ever seen, and it takes AGGRESSIVE action to protect the motor.  That means even slight variations in weather can result in the car pulling timing, and it also pulls timing if the temperatures of the car fluids start to spike.  As a practical matter this means we see dyno results vary by 20 hp and more with just a mild shift in the weather, or fuel, or coolant temps, etc.  If your dyno work before and after a change does not precisely duplicate weather variables and car temps and fuel you are wasiting your time and producing data that is not meaningful.

REVIEWS

Brian, just wanted tyou to know you've got another highly satisfied customer. I got my RoadstersportIII muffler on Friday, installed it in 20 minutes, looks and sounds awesome. I like the baffles out!! My new tires/wheels came Saturday, just got them on and test drove them. Fantastic!! And how they look--- just what I was after. I will add the front "mud flap" that looks like the rear one, for some stone protection, but the offset was just what I was working for. I'd love to send you some pictures for your photo gallery. If you'll send an adress via e-mail, I'll send some high-res photos showing clearances and side profiles, etc. The graphite spokes and polished rims really set well on my black car. Thanks again, me and my wallet will be back!!

After reading many other positive reviews on both the GWR and Miata forums I finally decided to buy this product. My main concern for many months was whether or not I was up to the task of installing the header. But with the excellent instructions on Brian's forum as well as several Miata forum threads it turned out easier than I expected. After receiving notice that the header would arrive on a Friday afternoon, I began the disassembly process. After about 3 hours I had the stock manifold out. Later that afternoon the new catted header arrived right on schedule. And it is a thing of beauty. I opted for the stainless version. Installation on Saturday morning took another 3 hours, although I could have shaved some time off of that but I was actually enjoying the process of double checking torque values and cleaning up my engine compartment. I already have the GWR catted midpipe, so that connection was a snap. I put everything back together, reconnected my battery, and went for a drive. NO CODES! Nice throaty sound with my RSII muffler, and a significant boost in power and low/mid torque. Another happy camper here. I since have added a M-E tune and I feel I have realized all of the gains that Brian has achieved on his 2012 project Miata. I've put several hundred miles on my Miata since the install with zero problems. This is the car that Mazda should have built all along. Thanks Brian.
