Lightweight Engines

[kee]

Been thinking about getting an engine to build up after iv finished putting all the current bits on the fez.

I want to get a light engine, so have been looking at k-series and suzuki G13b out of a swift Gti.

this will be for a future transplant into my fez.
i also want to be getting up to 200bhp.

anybody any experience with these engines, or other lightweight engines.
if i could keep it under 1.6 to save tax that would also be a big bonus
i am aware of a lot of hatred regarding the headgaskets on k-series, but thats not a big issue really.

Thanks in advance,
Kee

the baby zetec? keep it in the family?

[kee]

zetecs are heavy though

too much of this 'keep it in the family' going around for my liking, i want something different

Reliant engine! 598cc one for the ickle win. Sorry, that might be very silly but it is light! First all-alloy production engine I think?

oh right, i thought the zetec se(?) 1.4/1.6 was a pretty light engine, but i could be wrong.

huyabusa engine??

rotary?

A K-series would be a good bet, 140bhp out of the 1.4 in Caterham Supersport spec and doubtlessly more if you ditch MEMS.

ah yes sorry i thought you meant the bigger ones.

yeah they are all yamaha built all alloy.
could be done, not been done yet, but i would rather go 1.7 from a puma in that case if i was to do zetec.

Cappuccino engine? I think they have been taken to ~200bhp but it would cost a fair bit. If you get a late spec J one they weigh about curse word all, being a tiny three cylinder all ally engine. I think it may fit a wagon R gearbox, not sure though.

[rtlkyuubi]

yea them little 3 cylinder japanese engines! Daihatsu charade's have them.

vauxhall x14xe, quite light, very tunable, how that compares to your other options I'm not sure

[LowStandards]

I'd go rotary, Mazda 12a would fit the bill. There tiny, and for retrofit transplant purposes you can tax em on there actual capacity - 1146cc

There pretty damn cheap as well, £200 would see you with a complete one with a 5-speed hung behind it...

2 litre duratec from the mondeo will do what you want for virtually no money at all, its lighter than the x flow you have in there now, already fits on a fwd box and with TB's and mega squirt and a decent exhaust but no internal mods it will get very close to 200bhp while still being drivable, economical and relaible.

duratec in a mk4 here

Nice revvy light k-series. My 414 goes well with just filter & exhaust & will rev all day!
90 in 3rd on 17"s (speedo need calibrating...)

I imagine in a lil' fezza it'll be a blast!

[Mr K]

fiat punto sporting 1242 twink. iron block with an alloy lowside and head, but still weighs only a few kg more than a reliant engine (i.e. sod all) due to there being nothing of it.

[gazwad]

1.6 k series, with a big valve head, piper cams, TBs and emerald should see around 180bhp with good torque. and don't worry about head gaskets- put a new one on when you get it and just don't let it overheat and you'll have no problems.

Surprised no-one's mentioned any bike engines!
GSXR 1100 or 1300 Hayabusa, FJ1200, ZXR900, Ducati 916 as a wildcard?
Pick an air or oil cooled one and you've done away with a whole pile more weight...

1.6 has greater potential than 1.7

220hp on standard valve sizes Normally aspirated

G13b, 230bhp on TB's 400+ with a turbocharger!! All ally, easily available, and spares are easy to get hold of.

Bike engines are more hassle to transplant though, and not as streetable as car motors.
