Mazda has been showing off some outstanding capabilities in manufacturing high-end and reliable SUVs recently, and Mazda’s proposed EV line-up isn’t too far off. However, we have not forgotten about (and never will) Mazda’s old works of art. Placed among the best of JDM cars ever made, the Mazda RX-7 carries the spirit of the time.
For the RX-7, Mazda pushed the boundaries a little and tried out an unconventional approach; the rotary engine was a choice that made the RX-7 a true legacy. For the most part, the two-seat RX-7 gained popularity for its slick and smooth-running rotary engine. Besides, it was a lightweight sports car with a decent power-to-weight ratio. The third generation received a twin-turbocharged twin-rotor 13B-REW 1.3-liter rotary engine that revved up to around 260 HP. It was freaking awesome, and it stopped there. It was time for car lovers to take it a step further.
However smooth and effective, rotary engines need to be handled well. Also, it’s always welcome to revamp your car’s look, and a vintage RX-7 deserves some icing on the cake. Now, let’s look at some of the coolest modifications you can apply to your RX-7 to show what a dedicated owner you are.
Treating The Rotary Engine Gently Should Be Your First Priority
The lesser the friction, the more desirable it becomes; that’s a general rule for everything, and it applies to a rotary engine too. With a completely different construction to the usual reciprocating piston combustion engines, rotary engines tend to behave in a smoother way. The reason for that is quite simple: there are fewer parts for a rotary engine than a regular one.
That said, there’s nothing free of shortcomings. Rotary engines start to wear away after a certain amount of mileage (don’t expect me to drop a number!). Due to low thermal efficiency and also not-too-tough apex seals, it shouldn’t throw you a curve if some issues show up. That’s why you may want to keep a lookout for the heart of your RX-7 more than before.
What You Need To Consider For Pushing The Power Outcome
More power? Stout turbo kits? Grabbing a turbo or a supercharger and put it right into your car seems to be an easy way, but don’t rush into such decisions unless you want your engine gone for good.
First things first, you can take your chance with a new exhaust system, more preferably a crisp cat-back exhaust. Providing an enhanced airflow to the car, a cat-back exhaust system perfectly helps your soft engine breath—and sound—better. Indeed, gaining a considerable amount of additional power is an undue expectation. Rotary engines are smaller than smoky, wiry V8s; hence not much comes with a mere exhaust system modification. However, it’s a must-do if you want to enjoy a turbo kit.
Fixing up a new intake system could be the next thing you go with. K&K offers high-quality aftermarket parts for that matter.
If you’re lucky enough to own a stock turbocharged RX-7, make sure you take good care of it by doing modifications on your turbo’s intercooler. This helps the engine with more dense, oxygen-rich air, resulting in a better internal combustion engine. however, don’t worry if your engine is a naturally aspirated one. You can still grab your chance to add a fresh turbocharge kit to your RX-7. Either way, consider consulting an expert, and as mentioned, don’t risk your car’s life by carrying out the stages on your own.
The Best Modifications You Can Make On Coilovers
Upgrading your brakes with a new kit is mandatory, and the reason is as clear as day. Still, increased power would turn out to be hazardous if you’re stuck with your old, soft factory suspension. You can’t get the maximum out of your RX-7 unless you trouble yourself for some modification on the suspension as well. Coilovers are perfectly fine in various respects; not only do they improve the handling—especially when the speedometer has surpassed the limit—but also it brings your RX-7 into a more defined shape by establishing height and damping.
You can also have a good ride with air suspension. Of course, the Mazda RX-7 isn’t meant to travel on tough trains, but air suspension is always a suitable choice. It can lower and raise off-hand; thus, it protects you in all situations, offering more safety and comfort.
Cosmetics: Make Your Mazda RX-7 Glitter More Than Ever
Tire modification is probably the most prevalent car modification, regardless of the type of car. Its popularity is due to improving both performance and appearance., while it’s easy and fast. Tire companies including Michelin and Goodyear offer top-line aftermarket tires, though other models can ideally fit your RX-7.
Great tires that you can get a load of are:
– Barum Bravuris 3HM
– Yokohama DB AVS
– Toyo R1R
A new set of tires also allows you to embellish the look of your car by putting on some charming rims. There’s no special benefit to decking your tires up with glitzy rims, but a tuned-up, high-performance JDM legacy deserves a sporty look. You shouldn’t be worried about robbers taking your new set of rims because they come with specific bolts that don’t come off easily. What’s more, is a fancy rear spoiler that you can set up on your car. You can also install vendors or a scoop on your hood to boost the sporty spirit of your RX-7.
The Mazda RX-7 is one of the most popular Japanese sports cars in stock form, but everything can be improved with some quality mods.
