Atom's VTEC engine?
What is it? It's a 2 litre 4 cyl, but they are claiming 220 bhp. Is that factory performance or is it a preparation?
I'm kind of dreaming about putting one of these in a MX-5 because the car is fantastic but it doesn't move!
Cheers,
Alex

I belive it's a supercharged Civic Type-R engine. That's what I think I remember from Top Gear

I think the supercharged version of the atom is 300bhp.
I think the 220bhp is the i-vtec engine from an accord.
Or you could go for the S2000 engine @ nearly 240bhp from a N/A engine 
S2000

Displacement (cc) 1997
Maximum power (PS @ rpm) 240@8300
Maximum torque (Nm @ rpm) 208@7500

As Rug says:
The atom has a 300BHP supercharged Civic Type-R engine.

the atom uses the honda k20a engine which is out of the latest civic type-r. the k20a engine has more tuning potential than the s2000 engine, the k20a
engine is being used more in motorsport than teh s2000 engine i understand. the 300bhp is supercharged but the naturally aspirated versions come in
197bhp uk spec and 220bhp jap spec which is what most people are using in racing and the i believe the atom aswell.

Won't you have problems with engine rotation if its a honda k20a attached to an mx5 box (or any standard rwd box for that matter)?
I.e 5 reverse and 1 forward gear?

You want a mazda rotary engine in your mx-5 . As far as I know the mx5 box bolts up if you use the rx7 input shaft.

Noooo The whole point was that I love VTEC engines.. as much as I love the MX-5 mk1.. so I may well think of a different engine.. or maybe a
different car!
Engines hmm, that rotary one (RX-8), or maybe the Honda S2000 one (may have the same problem as the Civic Type R one, ie wrong direction?), or the
Toyota 4a-ge one (new Elise)?
I was just dreaming anyway..

Normal is getting dressed in clothes that you buy for work and driving through traffic in a
car that you are still paying for - in order to get to the job you need to pay for the clothes
and the car, and the house you leave vacant all day so you can afford to live in it.

The S2000 rotates in the conventional direction.
Go rotary - think of the noise!

He he he he, that sig is really good, oh wait, I drive a Fireblade Locost!!
It's interesting how bike and car engines are getting closer sometimes, with this 1400 cc 200 bhp new Kawasaki superbike coming soon, and these
jap car engines with low torque and high rpms.
BTW do you think either the S2000 or the rotary would actually fit?? I was surprised that the MX-5 is a really, really small car (you can park it
anywhere).
Also, can you get anything in the region of 220-230 bhp out of any of these two? (More or less reliably and without spending mega €€€.)
Oh, also I've seen that there's quite a lot of performance aftermarket stuff available for the original MX-5 engine (turbos and things)
but I don't think it's worth considering getting 230 bhp from the 1.6 if reliability is important.
What I really wanted is that VTEC!!
Cheers,
Alex

There's not many engines smaller than a rotary and they'll certainly make the power you're after.

Just remember to keep it cool, they really don't like being overheated.

These guys:

do turbo and supercharger kits for the MX-5, 300+ HP in some applications.

That's interesting if it can be done reliably, I suppose small means relatively light as well (I know nothing about rotaries). If coupling is
relatively easy, that's another plus.

Not necesarily! You can put a v8 in a Locost, and you could never put that in a MX-5. It's a very very small car really!
quote:
as for the power 230bhp is acheivable with the s2000 although you would have to restrict it a bit 
(237bhp as standard )
Oops!!
Also the RX-8 has about 230 bhp, so with any of these two I'd get what I aim for directly from the engine designers (rather than from
aftermarket preparation). That should add to peace of mind as for reliability.

Alex

In the UK, Brodie Brittain racing offered a turbo conversion for the MK1 MK-5 that didn't affect the manufacturers guarantee in the same way
that Elford garages had marketed a turbo conversion for the MK1 RX-7 a few years previously.
To retain the Mazda's warranty, the boost was kept to reasonable levels, but more stupid/desirable conversions were available too.
Might be the easiest route to follow.

Neil.

Not true! There's at least one RV8 MX-5 out there.

'tis true, it's mine - I just (I think) sold the car for 4&1/2 grand, it has the 4.6 motor now with quad 44IDF webers - making room
for the '7'
The engine fits fine, you just have to be a bit creative with exhaust routeing!
