Low weight engines
At the Swedish Locost forum there is some discussions about low weight automobile engines and since I know very little about the subject I thought
I'd get your input on the engines mentioned and perhaps some other suggections.
- Suzuki Swift 1300 GTI
- Fiat FIRE 999cc
- Nissan Micra 10K
- Daihatsu 3cyl turbo 1000cc
- Subaru Trendy, 1200cc 3 cyl
- Rover K-serie 1800 cc
- Toyota 4-AGE
- Honda B16A1 /A2

Some of them are light, but aren't they a bit shit? (eg Micra! about 60 brake horse as a guess, Fiat Fire about 50?).
If weights your thing, take Rell's advise - can't beat a bike engine for weight/power.
I use a 1660 XFlow, and its fast enough with 115 bhp at the wheels, and i cant see much of a handling penalty over a lighter engine.
Hope this helps.

take a look at the 13B mazda rotary engine 190lbs and 250bhp in std form. and with people generating > 500bhp with larger single turbos you really
cant beat it.
the main problem..... finding one. I got mine for 300squid brand spanking new, but deals like that dont come along very often

Currency converter...
300 squid = £300.
£300 = 3900 Swedish Kroner or 430Euros.
 hope this also helps!

why not go for the mazda 20B engine ok a bit heavier with the exsta rotor but you can get 900 bhp out of one 
now that would be silly
for all you non Believers http://cp_www.tripod.com/rotary/pg20.htm

AFAIK they were all turbos, only the newer RX8 kind are N/A.

Don't be so quick to dismiss the FIAT FIRE engine (silly name eh?) My first car (not so many moons ago - honest) was a Panda Super with the 1
litre engine. Could easily spin the wheels in 1st,2nd and 3rd ! also took a hell of a thrashing (police stopped me at 105 on the M1 - they said out of
amazement!)
it even managed to keep up the same performance after i had cross threaded a Spark plug in the head and just left it half hanging out!
I think with a little tampering it could easily out perform some of the heavier engines out there. In fact there was a company in the UK (they have
apparently ceased trading) who psecialised in producing Full Race versions of this engine.... - I note that Team Pandamonium now use bike engines
though....
Combine a tuned engine with a really light car and you might just be onto something... not in the same league a BEC of course but a LOT
cheaper.....

13b's come in NA form too, I've got one!
There's quite a range, most about 150-160 bhp standard with the restrictive intake and emissions nonsense, easily upped to 200bhp with no
internal porting.

All this talk of 13B's is getting me excited. I'd like a 13B (probably n/a, but I don't mind a turbo) but it's got to be
complete (ECU, exhaust etc), with a box, close to home and cheap. Note: Cheap!
Neil.
p.s. Did I say it had to be cheap too?

Yeah, mine cost me 400 lovely squidleys, but it did come with the rest of the car, admittedly not much of the rest of the car and what was there was
pretty battered, but that did include delivery from somewhere devon way all the way across the country to essex!

My car has a VVC 1.8 Rover K and it's a great little thing. A recent report reckoned that the problems some engines have experienced are down to
poor dynamic balancing by tuners. The current VVCs have 160brake standard, but if you want more I believe the non-VVCs are considered easier to tune.
Incidentally my 155ish bhp engine also has 128ft/lbs and pulls my 700kgs of car like a train!

I agree with protofj, the fire engine can be tuned to over 100BHP without the turbo, you can pull 65BHP out of a standard 999cc panda engine by
fitting the cam, carb and dizzy from a 4x4 to the nornal 2WD HC engine, it revvs to 8000 without problems and weighs less than my pinto head!
I could not find a gearbox to fit mine so went pinto instead, shame cos I had the engine in storage ready!
PS How did you know you were doing 105?, the speedo stops at 100 - I have been 100mph and 3/4 " on the speedo , so ner
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

The Elford Turbo was a post-import conversion from Vic Elford that didn't invalidate the Mazda warranty.
It uses a blow through carb and runs around 6psi. There was a factory 12A turbo that ran with FI, but that was Japan only.
Cheers,
Neil.

There are problems with bike engines (needs high rev, no reverse et.c.) that make a small, light car engine easier to use. Also according to the
swedish regulations you can only have a quite limited power to weight ratio.
Btw, have anybody looked at using the Ural bike engine? They have gearboxes with reverse and they are quiite inexpensive.

The 1989 swift GTI is the fastest (of the swifts) as they have hollow cams plus other gubbins., they are very revvy engines and would be great for a
locost. You could use the gear box from a subaru Justy (1.3 4WD) but make sure you get the right MK.
I think they have about 100 BHP as standard but with a lot of money they can reach over 250 BHP. Obviously this results in an unreliable engine.

, have anybody looked at using the Ural bike engine
They are also prehistoric and do about 70mph flat out. They only have reverse in the right hand sidecar configuration as well, not in UK version.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.
