WATCH: Easy DIY Curb Rashed Wheel Repair!

Sooo we kinda f-ed up one of the SSR Professor SP4 wheels on Project V8 RX-7 pretty bad backing into a curb a couple weeks ago.. With nothing to lose and no time to get it professionally repaired before LS Fest West last weekend we took a stab at fixing the curb rashed wheel ourselves! 


WATCH: Project V8 RX-7 gets ARP wheel studs, wheel spacers and a new set of nuts!

We were so excited about our new Sikky shifter video that we almost forgot to show you exactly how we approached new lug studs and spacers for the rear. We did a pretty good job guessing what offset would give us that perfect flush fitment of our SSR SP4 wheels on our Rocket Bunny widebody RX-7, but there was still room for improvement! We took care of all that with a set of 10mm FIC spacers, new ARP wheel studs and Muteki lug nuts!

5 years ago we installed Sikky Manufacturing's original T56 Magnum relocation shifter, and it served us well, but now they've updated the design. We got our hands on one to compare and install in Project V8 RX-7! Click to watch and see more!


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.

From custom fabricated control arms to revalved KW V3 coilovers with HLS, Mike Kojima goes under Project V8 RX7 to explain everything we did to address the new suspension geometry challenges we faced when adding 50mm to each corner with a Rocket Bunny wide body kit.


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.

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: 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”!

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!

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 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.

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 Car Update:  The V8 Edition

By Colin Holte

A quick glance at the project car column should tell you that MotoIQ has a large (and ever expanding) roster of project vehicles.  With all these vehicles it can sometimes be tough to keep the updates flowing for each.  In some cases vehicles may have even been sold but we still keep them on the project roll for posterity.  These articles are intended to share a little bit of the details with you of where some of the project vehicles that haven't seen the spotlight in a while are at in their evolution.  In this installment we check in with the V8s:  Project Mustang V8 5.0, Project Tundra, Project V8 RX-7, and Project Lexus IS F.



Project V8 RX-7: Goin' Legit (Project RX-7 vs the State of California)

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.  


Project V8 RX-7: Part 12 - The Intake & Moment of Truth! (VIDEO INSIDE)

by Jeff Naeyaert

Welp, the last day of Project V8 RX-7 Week is upon us!  If you’re a rotary zealot or Vh8er and we’ve been pissing you off all week, your suffering is almost over my friends!  All we've got left is the intake and this son of a bitch should be ready to roll! 

Project V8 RX-7: Part 11 - Finishing the Driveline

by Jeff Naeyaert

The end is in sight!  Only a couple of things left on the TO DO list and the most glaring is our driveshaft and rear end.  Ordinarily this wouldn’t be a really big deal; you just get up under the car, take a few measurements and head to your local driveline shop where they can either modify your old driveshaft or build a whole new one.  But we've got a few other things in mind! 


Project V8 RX-7: Part 10 - Power Steering

by Jeff Naeyaert

We want power steering!  Even though our RX-7 is pretty light at 2,843 pounds with 3/4 of a tank of gas (to be exact), doing 3 point turns in the neighborhood or negotiating parking lots sucks.  That suckness is compounded by the smaller 330mm Sparco steering wheel we're using.  Some argue you get better steering feel at higher speeds without power steering, but the best argument for NOT having power steering in your V8 converted RX-7 is that it’s a buttload easier to just plumb a bypass line on your power steering rack and ditch the power steering altogether.


Project V8 RX-7: Part 9 - The Exhaust

by Jeff Naeyaert

The title picture already gave it away, so I’ll save the prose, it’s time to build an exhaust!  This isn’t going to be a sissy grandma exhaust either like on Project G35 whose owner couldn’t stand how loud the Berk exhaust they originally installed was… in fact, it's the same folks at Berk that are gonna kick it up a notch and help us make a super bitchin’ set of pipes that’ll make children cry and leave no question in any Rotard’s mind that our dead Wankel was replaced with a big ol' hunk of American Iron aluminum!


Project V8 RX-7: Part 8 - The Shifter & Some Engine Dress Up

by Jeff Naeyaert

Hey guys!  Long time, no write.. I'm sorry.  We've had a lot going on and recalling the last episode of Project V8 RX-7 I hastily titled it “Bringing the E-ROD LS3 to Life (Almost),” which unless we were going to do a lame “(REALLY Close Now)” followup article, committed us to have a running engine by the end of the story.  Unfortunately, there turned out to be a lot of things we still needed to cover before turning the key—so much so that our article woulda turned into a novella and lost the attention of even our most devout reader by page 12!  Thus, Project V8 RX-7 Week was born! 


Project V8 RX-7: Part 7 - Bringing the E-ROD LS3 to Life! (Almost)

by Jeff Naeyaert

Now that we've checked "mount the engine and transmission" off our E-ROD LS3 swap checklist we can turn our attention to all the little things needed to get our RX-7 on the road.  What's left?  We need a fuel pump, cooling system, shifter, driveshaft, exhaust and we still have all the wiring left to do.  In this episode, we figure we can tackle the fuel and cooling systems as well as the wiring before we put you to sleep.  Let's get to work!


Project V8 RX-7: Part 6 - Installing the E-Rod LS3

by Jeff Naeyaert

In our last installment of Project V8 RX-7 we took a look at the T-56 Magnum transmission from Tremec we’ll be using for our swap, now it’s time to bolt it up to our E-ROD LS3 and get this engine in already! 


Project V8 RX-7 Choosing a Transmission!  Tremec T56 Magnum

Project V8 RX-7: Part 5 - Choosing a Transmission, the Tremec T56 Magnum

By Mike Kojima

When we were contemplating the buildup of our E-ROD powered RX-7, we planned to bolt up the same T56 six speed transmission that we had in the car when it was LS1 powered.  This plan went to crap shortly before we decommissioned the 7 for the E-ROD swap when while driving under normal conditions--nothing abusive or even brisk for that matter--the transmission got itself jammed in 3rd gear and no amount of muscling could free it.


Project V8 RX-7: Part 4 - Dressing the E-Rod

By Jeff Naeyaert

So we’ve got our E-Rod kit, unpacked everything and laid it all out, but curiously missing are all the spinny things that go on the front of the engine—more specifically, the alternator, power steering pump, a/c compressor and the other pulleys and tensioners necessary to keep everything playing together nicely.

Project V8 RX-7: Part 3- Inside the GM LS3 Cylinder Head

By Mike Kojima

In the last edition of Project V8 RX-7 we looked into the bottom end of our EROD LS3 engine to find that the modern Chevy V8 is a far cry from the old small block Chevy of years past.  Lately on some forums that cater to import performance, there has been a huge backlash against the LS swap, particularly into Nissan S chassis and RX-7’s.  All sorts of bleating noise from uninformed sheep decry putting “NASCAR” engines and the like into the S chassis. Purists claim that putting in a domestic engine somehow is making their favorite cars all the same and causes them to lose their soul and other things not defined by logic.  Such is the garbage cluttering the net these days.  Like many FFF facts on the interwebz, their are many fundamental inaccuracies to these statements.

Hybridnoun- the offspring of two animals or plants of different breeds, varieties, species, or genera, esp. as produced through human manipulation for specific genetic characteristics.
In what was nearly a generation ago, a fire was started in the Sport Compact performance market. Some guys on the west coast started dropping DOHC B series engines from the Acura Integra and H series engines from the Prelude in to the smaller Civic, dumping out the SOHC D series econo motor. The creation was called a Hybrid and in the smaller lighter Civic the bigger engines produced amazing for the time performance and launched a huge industry that for awhile dominated the modification scene creating a lifestyle of its own. Import Performance. This generation was rooted firmly against anything domestic. Domestic offerings were considered unrefined, unreliable, unsophisticated and redneck.
