Andrew, you'll have to rent it as the seagull scene is very funny. You may even find a clip on your interweb thingy.

WELL SAID

but maybe bmc knows it all then.
oh i remeber he said he was a rocket scientist.
thank goodness a series engines are a bit easier to work on.

well seriously, disc brakes modified who cares it is your car and we can do what we like.
we all have different reasons for modifying.

and i would like a k series in my van without a doubt

Finally somebody was brave enough. And I'd like a K-series too

Nikki,
Do you take your Moggy to the States then as you say "motorway and freeway". Sorry to hear about your ill relative in the States, hope they made a good recovery.
Ian.

Well folks, just go for it - I'm sure Jonathon can arrange a special offer for bulk buying - even BOGOF (buy one get one free) - works for the supermarkets

Ian, I'm thinking of emigrating to Canada (my mother is Canadian)... and my girlfriend, 'MeriKate, is American with family in VA.

If I knew how to post pics (or had the time ) I'd be happy to post the rebuild as it progresses, if anyone is interested.

If I could I would, so someone please find the space to post this I'd love to see the rebuild for the K Series.

Regards,
Wal

I could host the pictures on our branch website as a 'feature'. Shame the modified/custom register is not sorted out yet as that would be an ideal place to host them.

If you wish me to host the pictures Jonathon and post them please e-mail them to me: cam.shaw@mmoc.org.uk

A K series engine makes great sense and after having bought something from JLH i wouldnt doubt the engineering quality. The only reason I went with a mazda rotary engine is because i am a massive fan of the engine.
However i am also guilty of having a 948 on an engine stand and a head from a fiat uno sitting on a bench close by to see if they might get on. Chances are no they wont but I really love engineering and the thought of an opverhead cam a-series is pretty cool to me. Hence why I think the BMW conversion is just another way of giving someone something they want and what suits them.
cheers, michael.

Err... sorry to spoil the twin-cam party but one of the things I really like about the A-Series is the push-rod design. No need to worry about snapping cam-belts or losing the timing when you change the head. Plus no fuel injection or ECU.

I suppose it boils down to what you like about the moggy - I am a great admirer of simple engineering and therefore wouldn't want to change to an engine with an overhead camshaft and fuel injection. Plus there is so much that can be done to tune the A-Series to get more than enough power for most people's needs.

Having said that, I've never driven a K-series car...

I don't think you have to keep it injected, if that sways you

Post by **chrisd87** » Mon Mar 13, 2006 7:17 pm

Hmm... maybe if you replaced the timing belt with a chain too

Suppose I just like ye olde things too.

Post by **bigginger** » Mon Mar 13, 2006 7:50 pm

Me too - but I STILL want one. I'll put it with my Quandary, in between the rock and the hard place

You can run the K series on Webbers if you really want to but injection is the way to go in my opinion. Its reliable and economical, plus it offeres greater torque than the carb route. I understand the reasoning behind the keep it simple theory and I do agree with you. But the modern electronics and injection systems seldom go wrong. Maintenance on our K conversions could not be simpler as all you need to do is change the oil and filters plus check the plugs everything else is set or automatically adjusted. The timing belt on the K has never posed a problem, but for added peace of mind a double width performance belt is available.
I can say though that driving a K powered Minor will change your approach to how these cars are generally percieved and driven. I'm sure Nikki will second this.

Would i be right in saying that the K series is prone to blowing head gaskets if the coolant level drops too low? I met someone that had a freelander and this happened.

Post by **chrisd87** » Mon Mar 13, 2006 8:18 pm

I guess you're right re the reliability of injection and timing belts, but I can't help but like simple mechanical things that work well. I suppose I like the easily adjustable element to carbs too.

And I'm probably best kept away from fast cars, experience has shown

Post by **jonathon** » Mon Mar 13, 2006 8:28 pm

Yes you are correct, but only when fitted into the original vehicle and when running both a lambda sensor and closed loop injection. There are several tricks to improve the cooling , the first is to reposition the thermostat which is normally sited to get the engine to a very high running temp before the water is introduced to the rad, this method is needed to meet emmisions, but can fool the owner/mechanic into thinking that because the rad is cold that then the motor is also, susequent overheating can occur.We also use very efficient alloy rads with twin 10" fans, plus the Minor offers a much greater grill area for cooling than most standard Rovers.

The A series will soon blow it's head gasket too if you let the water level run too low !!
