Probably because they have a reputation for head gasket failures if you don't spend 15 minutes warming them up??
I don't think that' anything to do with it really. I think the causes liner heights, the original plastic pegs, head gaskets themselves. It's obviously better to warm an engine before thrashing it, but that's not the primary cause of HGF.Yoyoman said:
Thank you all for your feedback.
I think I will probably go with a sigma engine.
Whilst a k series is tempting, I haven’t got the knowledge to change head gaskets and don’t want the worry of one going on me. Or maybe I should hang on a few months to increase my budget and get into a Duratec ??
A K's the way my man.I think I will probably go with a sigma engine.

I once had a 130bhp 1.4ss with the 6 speed box and it was a sheer joy and for me the absolute sweet spot in a Caterham.
Dave Andrews (DVA) who posted earlier upgrade it to a 1.8 and whilst as usual he did a fantastic job and the engine was superb (a lot more grunt) it lost the sparkle and rev happy nature which made the 1.4 such a joy to use.
So K all the way for me and if you can get the 6 speed as well so much the better!
...and I always recall Dave telling me that 4" liner height was the way to ensure HG longevity.

I reckon that one day history will look back fondly at the K-series in a similar way that we look at the Lotus Twin Cam now. Its a truly innovative piece of British design, underappreciated (even maligned) in its time, later understood, developed and appreciated for its character and historical significance.

Im an ex k series owner. I had a 180bhp 1800k which was built by Dave Andrews, It revved like buggery as I had my limit set at 8500rpm on standard rods and pistons. It was mad and sounded fantastic. I wasn't shy with it either it was thrashed and driven hard with flames, pops and bangs. In 4 years i never had a problem, with it only costing me oil changes a clutch and general service items in my ownership.
I did have a 1.6 sigma for a weekend. It was fun but didn't seem to have the rasp and raceyness of the k series. If the k series are well looked after and built properly they are a reliable fun light engine which matches the caterham chassis well.

The other option is try and get your hands on a Superlight twenty which are based on the original superlight albeit with a sigma engine, 6 speed and lots of carbon and represent good value in CATERHAM terms.
A friend of mine has one and loves it.
I have never owned a K series car, but I’m on my second Sigma powered Caterham and mine is a Superlight Twenty. If you are going to get a Sigma car, I would definitely recommend looking out for one of these. They have all the bits you want as standard like the 6 speed box, big brakes and loads of carbon. They are lighter than most of the current range too. Caterham quote 498kg! There were only 20 of them made, so it’s nice to own something a bit special. Standard, they are 135bhp which is enough for the road. If you want to take it on track, get the 310 upgrade done by Caterham to get to 152bhp. If you want to go really fast, speak to Premier Power and they can take it over 200bhp if you really want! On mine, I’ve had the 310 upgrade, and a set of throttle bodies and ultralight flywheel and clutch fitted by Premier Power. I’m never going to sell mine, but I would try and get one of the other 19!

I've got a very original Superlight ( 007 ) , which is having the carbon refurbished at the moment, I've also got a 1.6 Sigma Supersport.
Both very similar specs, though the Superlight has the 6 speed gear box and big brakes and lots of carbon.
Price wise I would say the Superlight is worth £17-£18k
Sigma supersport spec £16-17k
Looking forward when this lock time is lifted to see which is a better car.
