Project V8 RX-7: Part 17 – Eimer Engineering Arms, Wheel Spacers and the Hunt for Perfect Stance

by Mike Kojima

In our last articles about Project V8 RX-7, we left you last with photos of our new SSR Professor SP4 wheels and Toyo R888 tires looking flush, but we weren’t ready to explain how we accomplished that task yet. With our Rocket Bunny aero kit giving us a huge space in the wheel wells to fill, we were going to take advantage of all of that.

Our car had to use all of the space for wide wall-to-wall rubber. More rubber means more grip, and with our LS3 providing the torque and power to use it all, we were obligated to do so. However, just putting wide rubber on a car not designed for it creates a few technical issues that, since we are MotoIQ guys, have to be engineered out of the equation. This means the typical spacer to fit and beat to match approach was not going to be a solution.

Project [Rotary] FD RX-7: Part 6 - V-Mount Cooling System (Overview and Intercooler)

by M-P Spierer

The cooling system in the FD RX-7 is widely regarded as its most glaring weakness. Many of the engine's cooling components are constructed out of plastic, the intercooler is wildly undersized, and the orientation of the radiator does not allow for proper airflow to the intercoolerIn the next two installments of Project [Rotary] FD RX-7 we tackle these issues by implementing a 100% custom V-mount cooling solution.

Project V8 RX-7: More Oiling Insurance from Improved Racing, Accusump and Earl's (Part 2 of 2)

by Jeff Naeyaert

In Part 1 of our improvements to the Project V8 RX-7's oiling system last week we got an oil cooler, Ano-Tuff fittings and Pro-Lite 350 hose from Earl's and an oil thermostat from Improved Racing.  In Part 2 we'll finish it off by walking you through how we put it all together.

LS3 V8 RX-7 Accusump

Project V8 RX-7:  More Oiling Insurance From Improved Racing, Accusump and Earl's (Part 1 of 2)

by Jeff Naeyaert

It’s no secret the LS family of engines can have oil starvation issues particularly on the racetrack. In high-g turns oil is forced to once side of the pan leaving the oil pickup dry and thus starving the oil pump and the engine's components of oil. Catastrophic damage can result in as little as a few seconds depending on engine speed.  We already installed an Improved Racing oil pan baffle, today we'll go one step further to protect our E-Rod LS3!

Project V8 RX-7 SSR SP4 Professor Wheels Stoptech trophy brakes toyo r888 tires

Project V8 RX-7: Wheel, Brake and Tire 3 PART MEGAPOST!

Part 3 - The Wheels and Tires Meet the Brakes and Body Kit

by Jeff Naeyaert

In Part 1 of our Wheel, Brake and Tire miniseries, we ordered a set of SSR Professor SP4 wheels for our RX-7 from Tanabe and were patiently enduring the two month wait for them to be built in Japan. During that time we fitted our car with a Stoptech Trophy big brake kit (in Part 2) hoping they would clear the wheels.  Right on schedule our wheels arrived and we were able to pick them up from Tanabe's facility in Torrance!  In Part 3 we’ll finally see how close all our guesses were to being “good enough”!

Project V8 RX-7 Rockebunny RX-7 Stoptech Trophy Big Brake Kit

Project V8 RX-7:  Wheel, Brake and Tire 3 PART MEGAPOST!

Part 2 - Stoptech Big Brake Kit

by Jeff Naeyaert

Ever since our projects, Project FR-S and Project STI got the Stoptech Trophy kit on them and we felt how amazing and confidence inspiring those brakes were, we HAD to have them on the FD.  After all, it IS our flagship project and that nickel finish is just way too bad ass and EXPENSIVE looking!  Stoptech makes a Trophy Big Brake kit for the FD RX-7 and those are the brakes we alluded to in the last article that our wheels needed to clear!

RX-7 Toyo R888 335 tires on SSR SP4 wheels

Project V8 RX-7: Wheel, Brake and Tire 3 PART MEGAPOST!

Part 1 - Huge Wheels and Tires from SSR and Toyo Tires

by Jeff Naeyaert

Two installments ago we put the Rocket Bunny wide body kit on our Project V8 RX-7 and if you remember it was looking pretty damn stupid on the stock wheels and tires inboard at least 6 inches on each side.  In Part 1 of this 3-part update we'll be feeding you over the next 3 weeks we get some ridiculously large tires for our FD and try to find some wheels to match!

Project [Rotary] FD RX-7: Part 5 - Cooling Oil and Generating Spark

by M-P Spierer

Whether it's high RPM, high power density, or for some, high failure rate, the word "high" is regularly used to describe various attributes of the rotary engine.  Today we are fighting against the rotary engine's high inclination for dangerous oil temperatures and ignition break-up. This requires significant upgrades to both the oil cooling system and the ignition system...and by upgrades, we of course mean complete redesign.

Project V8 RX-7: Part 15 – Major Suspension Overhaul

by Jeff Naeyaert

A couple of annoying sharp eyes on our last update a few weeks ago revealed that we had some KW suspension bits on our RX-7, so we've been forced to get off our lazy butts and write about them, some SuperPro bushings and a bunch of Improved Racing suspension goodies we put on as well in our attempt to make Project V8 RX-7 not only corner as well as it goes straight, but also remain tolerable and civil for daily driving.

Project V8 RX-7:  Part 14 - Going Wide with Rocket Bunny's new FD3S Widebody Aero Kit

by Jeff Naeyaert

If you follow us on our Instagram or Facebook page (and if you don’t why the F not?  seriously, click up there on the top right of the page and connect!) you know we received one of the first batch of FD RX-7 Rocket Bunny kits to come into the states!  If this seems out of character for us, it is—never in our history have we put a bodykit on one of our project cars—and for good reason, most of them look terrible, are molded poorly and are difficult to install.

Project [Rotary] FD RX-7: Part 4 - Turbo System

by M-P Spierer

Designing and installing the turbo setup is one of the most enjoyable aspects of any build. There are many decisions to make when planning out a turbo setup and each decision has significant effects on subsequent decisions. It is a balancing act of desired goals and undeniable trade-offs. Many questions need to be answered like, am I looking to maximize mid-range response or top-end power? And, how much response will I be giving up if I choose one turbine housing A/R over another? These are questions that have different answers for every build. For this RX-7 we are trying to maximize response around a specific power limit without breaking the bank.

Project [Rotary] FD RX-7: Part 3 - Fuel System (Chassis Side)

by M-P Spierer

Fuel systems upgrades vary drastically and sometimes only a simple pump or injector change will suffice. Other times, like in this project, it seems like every component in the entire system needs to be changedRecently, in Part 2 of Project RX-7, we covered the engine side of the fuel system, where the injectors, rail, and pressure regulator were upgraded. Now it's time to discuss the remaining fuel system upgrades that we are so eloquently dubbing the "chassis side."

Project [Rotary] FD RX-7: Part 2 - Fuel System (Engine Side)

by M-P Spierer

There are three key ingredients for combustion in any gasoline engine: air, fuel, and spark. Parts 2 and 3 of this project will focus on the fuel component of this recipe. Rest assured, this won't be your typical run of the mill RX-7 fuel system.

 Modified StreetCar Shootoout Full Race S14

2013 Modified StreetCar Shootout - The Rules, The Cars, The Big Tease.

By Wes Dumalski and Sarah Forst 

Like all good stories, this one starts on the airplane while on line for the shitter. I hear a voice come up behind me “my GOD this woman won’t shut the hell up”... I turn to fund the animated Bill Caswell and we begin bantering about this woman on the plane who had been talking about absolutely nothing at all for 2 hours. I am on this plane and talking to Bill Caswell because I could not get a refund on my Expedia package and rather than let the tickets go to waste I figured I could still head to Arizona and cover the UMS tuning time attack event and find some good feature cars. As luck would have it two complete car nuts are on the same plane heading to the same place to do the same damn thing; be geeks.

by Jeff Naeyaert

Now that it doesn't look like the world is gonna end we need to get our RX-7 smog legal and on the road!  Since the car has been down for surgery with the heart transplant the registration has long since expired. It's only a matter of time before we get busted by the fuzz for old tags and excessive hooning around.

Mad Mike's 500 Horsepower N/A Rotary V8 Slayer

By Tatsunori Tsuchida

In 2008 a very special shipping container arrived in Tokyo harbor. Its final destination would be various drift circuits throughout the islands. The contents of the container, a RX-7, highly tuned by New Zealand’s best. Now this wouldn’t be the first time foreigners have drifted in Japan, but it would be the first time a foreigner had done it on such a large stage as D1GP.

Turbosmart Time Attack FC RX-7

by Khiem Dinh

The FC is the middle child in the RX-7 family meaning it doesn't get quite as much love as the other two.  The 1st generation FB was a pure sports car that really introduced the rotary to North America while the 3rd generation FD was (and still is almost 20 years after its introduction) sex on wheels.  The FC was designed to be a little softer than the FB, but it was still a better performance car all around with an independent rear suspension and rack and pinion steering.  Of course, you could also buy the FC with boost!  For the 2011 World Time Attack Challenge, the boys down under at Turbosmart decided to show that the FC is a highly capable car even with a simple build.

Rotary madness, motoiq

Rotary Radness, Mazdatrix's 13B REW/MSP Hybrid!

By Mike Kojima

So far we have not focused too much attention on the Mazda Rotary engine on the pages of MotoIQ.  This is not because we haven't wanted to but because no one on our staff has much expertise on the engine except for Eric and he has been pretty busy lately doing other things in the world of internal combustion besides messing on rotaries.
