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
/Carl
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.

On piston heads their is an ariel section http://pistonheads.co.uk/gassing/forum.asp?f=79&h=0
quite a lot of interesting stuff
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.
Ned.
Thank you everyone!
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.. 
reminds me of someones sig I saw the other day....

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!!

Alex

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

These guys:

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

the s2000 fits in an Mk Indy so i would imagine it would fit in an mx5,

as for the power 230bhp is acheivable with the s2000 although you would have to restrict it a bit
(237bhp as standard)
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.

Install the above engine and add this body kit....

[Edited on 22/9/05 by stevebubs]
didn't that belong to a mr bobc from this forum, the engine now resides with our esteemed webmaster i do believe.
Is that a comb I can see on the dash?......
'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!
Bob C
Oh yeah - the flyin miata turbos for the old mx-5 go well up towards 300horse using stock engine internals, just adding intercooler, aftermarket ecu
& clutch.
Also note the owners of these fearsomely fast peices of kit report reliability well into 6 figures and better mpg than stock.
Bob C
Most impressive, Bob
BTW I thought that the mk1 MX-5 engine was 115 bhp as standard (1.6), but the other day I was told my '91 has 90 bhp. Not that I care but
I'd definilety like to know if it's the same engine we are talking about here, i.e. the one you can get 300 bhp from.
Cheers,
Alex
I think the 90horse 1.6 came out with the 1.8 late in mk1 life, around '95 I think. I'd bet on a '91 being the more powerful
engine.
I heard it was based on the old 323 turbo engine so its innards were rather overspecced, including such details as oil jets under piston crowns, but
that's all old gossip & might well be wrong.
Bob
That'd be good news.
The other option, as I don't have a car for this yet (the one I have is my girlfriend's really, so I'm not trying!), would be buying
one with a broken engine, then putting a different engine in (being it a 1.6 MX-5 one prepared by "Flyingmiata", the RX-8 or the S2000
engines as discused). I can't find any of these engines second hand here in Spain, do you know where to find a rough estimation of price for them
in the UK, so I can weigh up wether or not a different engine is a better option than a preparation?
Cheers,
Alex

The rx8 isn't the only mazda to have a rotary engine, the older rx7's had them, many were turboed too with a good bit more power than the
rx8. If you're really thinking about it make sure you get one with low mileage cause they can be unreliable, other people here will be able to
further elaborate on what too look out for.
Mark
[Edited on 28/9/05 by Mark18]
Thank you Mark. I'm just evaluating different possibilities. If I finally try something, that'd be probably next year. Still I'm
learning very interesting things in this thread, which is good in itself
Looks like a standard rotary is less reliable than a MX-5 engine + huge charger (plus fitting it is more of a project). The resulting car would be a
daily driver so this is an important factor.

Alex
