On a couple of my vehicles during the summer months I remove the wiper arm assemblies for the aesthetic value of not having "*****" !


With wiper assemblies and without

I have a big brake kit project that I have been working on for a little while. I ran into an interesting challenge. The company that offers the kit does not offer the rotors drilled and slotted. I only like drilled and slotted for the looks and so I need to match the rears with the fronts. Easy enough to do. A few measurement's and a fast math problem for spacing the marks and a drill press.
A perfect pattern copy of the rears.

This is what the rotor and caliper looks like after I drilled the rotor to match the rear

Hers the rub. I bought 2 new rear calipers and painted them RED. I did not realize that the BBK calipers were Anodized RED. . So I guess I will run them as they are and when I need to service them will disassemble them and have them powder-coated to match the rear.

How to give me up to 50 real Horsepower increase with NO ECU calibration or extensive modification to any part on the engine.

I have been using Nitrous when it was un-cool and many called it a cheat. This was back in the day that if you did not know what you were doing with it disaster by way of melting pistons was common. I have used and sold most every better Nitrous system and have even offered custom Nitrous set up a few years ago in one of my shops. My 2002 MINI Cooper S has a 3 stage system with direct NOS Nitrous foggers in each of the intake ports as well a launch single stage and a IC cooler sprayer for mid 1/4 activation. So roughly about a 150HP shot system on my little base OEM 1.6 4 cylinder. LOL
About a year ago was bored to popped one on my MAZDA and dyno'd it. Dead on 50HP increase. I tried for 75 but the ECU grunted and placed the engine on limp mode. Oh well I cant get to greedy. Besides until I can get into the ECU and do some serious calibrating it fine that the MAZDA ECU will hold me back from "stupid". HA!
The NOS Sniper system is a very safe to use system that will work on almost any engine. Its easy to install and not permanent mounting. I did use a spacer plate at the Throttle Body that I had machined up for my water/meth system but after have trouble with space decided to make another spacer but thicker for all my engine "goodies".
NITROUS is FUN!

One of the starting engine mods I prefer to do to most of my rides is a larger Throttle Body. Unfortunately for the 2.5 SkyActiv NA engine no one offers a performance one yet? So I had to machine my own. I obtain a donor throttle body from a auto recycler and disassembled it. From there I machined the larger diameter without sacrificing the integrity of the main body by going to thin. The Throttle plate had to be made from scratch and it actually took a couple days to get the closed angle at 180 degree difference from the opposing edge correct. I counter sunk the throttle plate screws as best as possible considering longevity over the highest flow capability. I did however reduce the throttle shaft size so I think that compensated for the screws? The end result was a Throttle body that is 5% by volume increased. The engine will start and idle fine and after a few months on the engine has not generated any DTC's, loss in MPG or any other negative results. I did do a DYNO test to see what it actually did for the power at WOT/REDLINE. To preface after the engine was where I considered it to be broken in based on compression and leak down testing I ran a base line Dyno . It was also interesting but expected to see that Mazda like many auto manufacture sorta fudges on the power advertised. That is a thread topic all its own. My reason for doing an early Dyno baseline is for me to use for comparing future Dyno tests of anything I may do to the engine to improve it performance level in any capacity . The results gave me a surprise and I was pleased to see some positive increase if even so slight. Sorry I won't post the numbers it would be the ingredient catalyst for controversy? I personally ran all aspects of the Dyno test along with the program pre-set perimeters for the most realistic results and no SAE smoothing. In the end I was pleased with this project and to see some gains in power if ever so slight. I ran 3 Dyno runs to confirm the results and carefully adjusted the Delta's in the program to match the first run perimeters.
