So, we had the engine out...

It's certainly better than the facebook "Why would you ruin a Miata with a V8" discussions I have seen.

I saw a comment that was "Why would you ruin a Miata by converting it to RWD just so that you could put a V8 in it?"

Ha! I like that one. Save the FWD Miatas!

In reply to Keith Tanner:

I'll admit though that up until about 5 years ago, I though BB6-chassis Preludes were RWD. But I didn't pay much attention to Hondas back then and the proportions make it look like it should be RWD

So, Keith... you gonna have an LS powered ND running by Summer Camp?

Mostly kidding... I know you probably have higher priorities with the ND right now. Although I bet there's already a customer that wants the first one...

Actually, I think that would be a worthwhile goal. I tend to be the guy who sets big targets. Dunno if it's realistic, we need to have a council of war and talk this out.

And yes, we've got someone who's just itching to send us a car. If the R&D car changes to red, you'll know what happened.

What about CARB legality? Same deal as the NA/NB kits with the 430 hp e-rod?

Also, does the swap retain the sound tube?

Ooh, good one. To answer the question here before I update the page - the E-ROD EO only applies to cars built before 1996. To get CARB on this thing would require transferring all the emissions controls (including stock manifolds and cats) from a single donor car. Space constraints make this highly unlikely.

As for the sound tubes, we may not find that necessary. But if you want it, I'll find a way to keep it

Here's your "sound tube"

Oooh shiny

Well, here's a reason why not. That's an old SBF on the right, it's about the same size as an LS3. Coyote on the left.

The reason why GM is sticking with pushrods for the forseeable future for most of its V engines. They're WAY more space-efficient. You can cram more horsepower into a smaller space.

Also, way back when GM was developing the LS1 for the C5, they built a 4V DOHC engine and what became the LS1 and put them in a pair of prototypes and sealed the hoods and had the press drive the two prototypes back-to-back without telling them which was which and tell them which they preferred. The response was overwhelmingly in favor of what became the LS1.

The term is power density.
