1993 Mazda RX-7 Plasti Dipped Whole Car

So I picked up another FD about 2 months ago and I am trying to build it into a reliable daily driver with about 350 hp mostly stock, but with reliability upgrades. In order to keep my costs down and also to keep me from caring too much about the paint job and door dings at the parking garages, I decided to try plasti dipping the car. This is inspired from DipYourCar.com and will allow me to change the color of my daily driver FD every few months should I choose. The paint costs about $180 to paint the entire car, the only caveat is that it has to be a matte finish, though they do sell glosifier products, they don’t look as good to me plus I like the matte look.

Here’s the process of me dipping my car in an electric blue color, I still have to finish 1 final thick coat but ran out of paint. I am going to make the final coat electric blue mixed with matte black so it brings the color down a notch, I am trying to model the color after this color done by dipyourcar.com:

Here’s the car before hand, notice all of the different color pieces and the fiberglass that is unprimed. I wanted to see how far this plasti dip goes in covering up your mistakes and it really goes a long way! I have to fix a few spots but overall this stuff is GREAT at hiding issues.

I setup a make shift paint booth in my driveway and cleaned the car with the PlastiDip PreDip cleaner spray, as found here. I was spraying at night, which I don’t recommend but I had a really bright light, here’s the car after the second coat, I was spraying light coats to avoid bubbles:

Here’s the car after the third coat:

Here’s the car after coat #4:

Here’s the car after the 5th coat, I still need to do 1-2 more coats after I use their Fix Kit and repair a couple of problem areas. The final color will be a bit less bright and will be more like the Audi S4 showcased above:

RX-9 Rotary Rumor Mill Churning Again

There is news out of Japan regarding the RX-9. Whether fact or speculation, a few sources have now said that Mazda is working with Toyota hybrid technology. Whether the RX-9 will be the worlds first Rotary Hybrid sports car or not is remain to be scene, but it does appear that Mazda will enter into the Hybrid market very soon.

It’s an interesting notion that Mazda may deploy a battery cell system paired with the wankel rotary engine, for a few reasons. One being that the rotary engine has long suffered from poor fuel economy, despite it’s small displacement (typically 1.3 liters). Another interesting benefit is that electric motors provide low end power, which would benefit the infamously low torque found in the RX-8’s Renesis engine. There is, however, a major downside to deploying a hybrid battery system in the RX-9, and that is weight. A rotary sports car’s worst enemy is weight, and unevenly distributed weight would be a showstopper. If Mazda is able to properly balance the added weight from the battery systems, it is possible with other weight saving techniques, they could keep the sports car to a weight of around 3400 lbs (500 of which would be battery cells), which would not be the end of the world but would require the new engine to output over 300hp to be considered a proper sports car in this day and age.

Picture below is another concept that seems to be inline with some of Mazda’s latest prototypes, which typically foreshadow their sports car lineup pretty well:

The concept car that is rapidly turning into what is expected to be the basis for the styling of the next version of the 2013 or 2014 Mazda RX-7 (or possibly RX-9) was made public recently in a Mazda USA commercial titled “What do you drive?”. The concept car can be seen in this video at around the 17 second mark:

RSC Raptor GT 4 rotor, predictions for 2011-2012 RX7?

Shades of things to come in the 2011-2012 Mazda RX-7? RSC out of Germany has created a super car powered by a 4 rotor engine running on E85.

The use of E85 as a fuel system allows the German car-maker to pass emissions testing with a 4 rotor turbo charged rotary engine.

This fuel platform may be foreshadowing what Mazda may power the 2011-2012 Mazda RX7 with. Mazda has already developed a 16X (1.6 liter 2 rotor) engine, that may be brought to the US market with a turbo charger or supercharger running an E85 fuel system.

Body work and Paint on my 93 FD RX7

A KS-Auto Burnout Style Full Aero Kit was installed to my 1993 Mazda RX-7. Wide body flares were fixed to the rear fenders and the front fenders swapped out for new FRP material wide body fenders.

Here is an image of the body kit fitted initially:

The kit was made by Shine Auto and made from a (FRP) Fiberglass based material. There were many fitment problems and required some fiberglass work on every piece except for the side skirts. Here are some pictures of the kit after the fiberglass work was performed:

Additionally, the rare flares were molded in:

Interior Restoration on my 93 RX7

I purchased this car with a blown motor and trashed interior. After nearly 2 years of mechanical restoration I am now working on the interior.

To begin with, the interior was covered in a cheap carbon fiber dash overlay kit. Basically this is a carbon fiber piece that is glued onto the interior pieces. The glue was covering every piece of plastic in the interior, and took quite a bit of work to remove. Here is a before shot of my gauge cluster and other dash pieces:

First I removed the glue by scrubbing it with goo gone and water. Then I sanded the piece down using 600 grit sand paper, followed by a wet sand using 1000 grit paper. After the piece was clean and dry, I sprayed it with Duplicolor Truck Bed Liner.

This picture was after the first coat.

After a 3 coats, I let the paint dry and then I wet sand each piece with 1000 grit sand paper. This helped to remove the rough texture. The finished results are as follows:

This is the speedometer put back together, and after I painted the silver gauge rings (they had oxidized).

Here are all the pieces that I refinished:

Here is the current interior with the refinished dash pieces installed.

I have just purchased a genuine Spirit R steering wheel and shift knob. This is the Spirit R wheel:

As well as new floor mats:

I have also purchased a new JVC head unit.

Spirit R Shift Knob:

These items have yet to be installed, but should round off the interior beautifully. I have also elected to remove the steering column gauge pod as I am not happy with how it sits. I will instead be purchasing a new 3 gauge speaker pod instead of the current 2 gauge pod I have installed.

2011 / 2012 Mazda RX7 Concept Pictures

While no official word has come out of Japan as to when and if a new Mazda RX-7 will be put into production, the chief engineer at Mazda has gone on record stating that he will bring the RX-7 back during his tenure.  Many concepts have arisen over the past few years that are definite to be part of the new RX-7 styling, however no official design has been made public.  Here are some rumored concepts to be part of the styling:

The new RX-7 is rumored to be equipped with a new 16X 2 rotor rotary engine (1600cc displacement).  This engine is based on the side port technology used in the current RX-8 “Renesis” engine.  While this engine does improve gas mileage, it only produced a lack luster 235hp, and dyno’s of RX-8s are common to only show 180-190 rear wheel horse power.  This is a far cry from the original 255 flywheel and 225 to the wheels that the original RX-7 provided.  Not to mention the huge aftermarket gains the original RX-7 13B could provide (up to 350-400hp on stock block).

As a rotary fan, I am hoping Mazda will release a rotary engine capable of handling forced induction (whether it be a turbo or supercharger).
