Boss Frog V-8 Kit

Has anyone had a chance to look at the : miata.net site and looked at
What's New and Hot ? Page down and look at the Boss Frog V-8 kit. My
'62 Corvette was 2600 pounds and 365 HP. Just think of what a Miata
with 400 HP + would be like. And all that torque ????

Wouldn't it mess up the weight distribution quite a bit by
weighing down the front end and "lightening" the rear?

Combined with a light rear end, it might not be very drivable.
I guess with all that horsepower, you'd probably put in a 30
gallon fuel tank. That would add almost 100+ lbs on the rear
wheels.

They claim "only a few percent" difference from stock. Such a car is
definitely not going to drive like a Miata anyway, so it's probably a
trivial issue. Obviously, a survival-minded driver will need to exercise
some judgment regarding throttle opening.

Flyin' Miata offers a similar kit, but it appears to position the engine
a bit farther rearward, which requires some firewall cutting. It's good
to have a choice of less work versus better result.

The Australians solved the problem by making the Miata bigger. Stretch the
front, stretch the rear, add a bit of width, along with a turbocharged V-8
and new chassis components. (Bullet)

Don't know about that one, but we have 2 club members (father &
son) who have converted 3 or 4 Miatas to V-8s. IIRC they replaced
the entire drive train and suspension along the way. There's
photos on our website in the gallery. It probably helps that the
dad trains auto shop mechanics.

Better choice of engine as well. LS1/2/3 engines have aluminum blocks
and I would have to think they'd be lighter, more modern and more
powerful than the cast iron 5.0 from the Mustang.

An inconspicuous, modern day Cobra. With a salvage drivetrain it could
probably be done without breaking the bank.

Would there be any problem registering/insuring something like this? Do
you just sort of forget to mention the extra 200 horsepower, or what?

Both the Boss Frog and FM kits use those engines.

FM's website has a cost breakdown for a variety of build options,
including a turnkey car: http://www.flyinmiata.com/V8/costs.php

If you already own the Miata, it's a non-issue in most states. In
others, you'll probably never comply with emissions regs (CARB, etc.).

Insurance depends more on the driver than on the car. With a long, clean
record, it shouldn't be that bad for a car used only for pleasure. Never
lie to your insurance company--it's grounds for denying a claim, which
could ruin your life.

My bad. I was thinking of the Monster Miata.

Well, I think if you guys will go read the info. again, the last
sentance kind'a shows that they don't figure that you will use this car
to drive to work in. It sounds like they designed it for track or drag
use. For track use, the driver should know and be able to drive high HP
cars . I don't think it would be very hard to control this thing.

Use a really, really strong throttle spring...
