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!

Shorai Lithium Iron Battery (and Lots of Plumbing)

by Dave Coleman 

Shorai doesn't technically make any automotive batteries, but they have a full line of motorcycle batteries. I can't think of any reason why a motorcycle battery won't work in a car, and certainly not one powered by a motorcycle engine and charged by a motorcycle alternator. Shorai's direct replacement battery for the Hayabusa (theoretically all we would need to start a Hayabusa engine) weighs only 1.7 pounds!


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.

Tubular Subframes and Engine Mounts, Oh My!

In July, 2010, we posted Part 2 of Project Miatabusa and proclaimed, in a very carefully worded headline, "the engine is in!" "In" was the operative word. Not "installed", or "mounted" or anything nearly as accomplished as that. In fact, we had kinda faked it, hacking away with a plasma cutter to see just what the engine wasn't going to get along with. Now, finally, the engine is actually mounted.

Project Miatabusa Part 9: We Finally Found a Starter!

by Dave Coleman

Somewhere in the great wide world of starters, there's surely something that will fit in the notch between the Hayabusa engine case and transmission case, line up with the Miata flywheel, have the right tooth pitch for a Miata, and have an unshrouded pinion, right? Sure, but where?

Project Miatabusa Part 8: Miatabusa Gets the Shaft!

by Dave Coleman

The idea was to take the Hayabusa's relatively fragile transmission and replace it with a shaft that holds a Miata flywheel. That's pretty simple to say, but actually doing it...

What are you waiting for? Holy crap, click on this thing!


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.


Frankenmiata: Dyno Secrets Revealed For The First Time!

by Dave Coleman

Secrets? What Secrets? How about the secret to how we found 45 hp completely by accident? Or the secret to how we made 20 lb-ft of torque for $8.32?



Project Miatabusa Part 7 - Mounting the Gauges

by Dave Coleman

Last time we looked at cramming the Hayabusa's instrument cluster into the Miata housing, it proved to be a shockingly good fit. There was a very large unresolved issue of how to actually secure the Hayabusa cluster's circuit board, though. Here's how that project was finished:
