Street Glow 4500k headlights

This is a slight move away from the whole greencar thing, but I would like to talk about the Street Glow 4500k headlights. They are good. Simply put, they are BETTER than Sylvania Silverstars (though I have not data to judge longevity, I will soon) and they are a much better value.

 The Street Glow lights are brighter, bluer, cheaper and overall a much better purchase that the Sylvania Silverstar lights. I bought a pair for about $13 and I have been impressed with my purchase. I did have some problems with the original set since I purchase the “XS” variety (which are a different model, with different specs, brighter) and they burned the crap out of themselves. I replaced them with the 9006 that I really needed, went for a test drive and was blown away with the headlights. These are the bulbls to go with.  Overall, eBay seems to have better prices, so check there first. Please post a comment if you have any questions.

Monza Cat Back Exhaust System Mazda MX5 Miata 1990-1993

I finally purchased and installed the Pacesetter Monza Performance exhaust on my MIata and I have to say that I was very pleasantly surprised at the purchase and the value. The body of the catback is a sleek black with very nicely welded seams and the metal looks like it will last for longer than a couple of years (though not as long as a Stainless Steel muffler would).

It goes together relatively well and is quite easy to put on the car. The only problem I had was with the U clamp that came with the catback was too small and I needed a new one.

As for the sound, I like thr growl. The old (OEM) muffler was already loud from rust, but this muffler has a low throat on low revs and screams on high revs. I was suprised at the increased throatiness of the engine on addition of the catback and performance was definitely increased, more so than any other performance enhancement on my car. I would definitely suggest this catback.

As for the price, the quality of the product and the final outcome, I would have to say that this is a good purchase for about $170 and a weekend in the garage.

DIY Dyno at Home

This is awsome and only if you are the most dedicated wrench head or a computer geek should you read any further. But this guy has published plans for a homemade dyno using a timing light spak plug clamp, a laptop computer, MATLAB and some old fashioned geek ingenuity. Basically he records some numbers from a pre-measured drive across the countryside, measures the “clicks” from the timing light clamp and puts three and seven together to develop the dyno curves. Absolutely fascinating stuff! Check out the DIY Dyno Page.

Change oil in your Mazda

In keeping with my series on performing oil changes on my Mazda, I replaced and serviced the transmission, the transaxle and the engine oil over the past week. I found some very good resources online for changing my oil. It actually cost me quite a bit more than the service station since I needed a lot of the tools required to perform the changes, but I squeezed it under $200 for all three with my tools. Oh, I also replaced the spark plugs and the wires with Denso plugs and wires. They were quite expensive compared to the regular brand but I have read a lot of literature that suggests that the firing point of the Denso/NGR plugs are just right as compared to the ones from Bosch etc.

Miata.net Garage has a good section on changing oil in four places on your car including Trans., Gearbox, Shifter Oil Change Pics which I found really quite useful. The author had suggested to use either Redline or MTL but I could only find Valvoline 75w30 at my local car stores so thats what went into the tranny and the transaxle. There is also a nice article over at the Tech Guys page that gives you all the gory details of the torque specs and such. Make sure you buy the seals and gaskets before you open any oil drain plug. 😉 (Mine leaks at the seal because the previous owners ignored them)

Mazda Miata Enthusiast

Now I can be a little obsessive about a new things, but this guy in his Mazda Miata takes the freakin cake. I love his dedication, really appreciate his insight and in general have been really inspired by his website. If you like Miatas, it is worth the time to check out http://mymiata.paladinmicro.com/ Of special interest to me is his section on air intakes (I have decided to change my intake design due to this article, and others that I have read after I read his) and his praise of a Jackson Racing Supercharger. I really cannot afford the Supercharger right now but I am sure that I am going to get one.

A site dedicated to Mazda Accessories

I have to bookmark this for future reference. Parts I am interested in include the Venom 400 mod chip, the Racing Beat Power Pulse Muffler (along with required connector pipe) and the High flow intake assembly. The intake uses a K&N filter and looks very much like the one from “That Crazy Italian” (or something of that sort.

Mangnaflow Performance Exhaust for 1990 Mazda Miata

Doesn’t that look dreamy? I am looking to buy a high performance (and loud exhaust) for the Miata and the Magnaflow Catback exhausts seem to receive the most accolades. There are other, more expensive systems out there for much more money, but this looks very nice. I also have my eyes on a couple of Monza and OBX racing headers and stainless steel catbacks, but thats for another post. Till then, revel in this mandrel bend, resonator tipped beaut!

Dimensions = 4x9x18″ P-SS Muffler, 4x4x14″ P-SS Resonator, 2.25″ SS Tubing, 4″ Slash/P-SS Tips, Rear Exit. All MagnaFlow Miata Systems feature fast-flowing mandrel-bent stainless steel tubing, a straight-through stainless steel MagnaFlow Performance Muffler and a polished stainless steel rear exit tip. You’ll love the smooth, deep, throaty tone, and the extra torque and horsepower will make towing a pleasure. This system has the MagnaFlow performance muffler best suited to the needs of the vehicle. Included are all the system’s hardware, gaskets, and flanges for installation.

Mazda Miata MX- 5 Performance Projects

Being the eager beaver that I am, I wanted to get a leg up on getting my Miata up to snuff with performance upgrades. In addition, my friend Chris is also my mechanic and he suggested that I would really like the increased horsepower and the added fun. Also, since I want to make a lot of these upgrades myself, I figured a good book would be nice.
So I purchased the “Mazda Miata MX- 5 Performance Projects” from Amazon (used of course) for about ten bucks. I will have to post a review of this book once I receive it. I also bought a cheapie book on MIata history, but thats my geeky side showing. I cannot wait to get my baby tuned up for some country road swerving fun! 😉

Welcome to the Green Car blog

Well, green cars that run fast and are good on gas, namely my new (new to me) Mazda Miata MX-5. I am the proud owner of a 1990 Mazda Miata with about 150000 miles on it. It is going to be my project car, my beater and everything else in between. I am hoping to get more information on the car as soon as possible.

Though most of the stuff on this page is going to be about Miatas such as upgrades, products, tips and tricks etc, I am going to write about green cars, their reviews, worth, value and so on. So please stay tuned and if you are a tuner/wrenchhead yourself, please feel free to register and post your own thoughts.
