Does anyone know much about them???

Is the 350z engine getting lonely then.
Nope! It has 2 other engines to keep it company just now!
Wait for BT to reply. He seems extremely clued up on all things. Rover/mg
Very light all 2.5 engines are basically the Rover engines are the same only difference is minor changes in mapping ie the MG 190 develops less
than 190 bhp and the Rover 160 more than 160 bhp V6 and the 180 is the same as the 160. However these engines have any major jobs on them done
by the book and special tools are required for cam belt changes, like all K series they don't suffer fools I have seen one ruined by the bottom
sprocket bolt not being tightened to spec. Only real problems with them tend to be leaking thermostat housings and the variable inlet manifolds
motors sticking.
140 bhp 2 litre V6 is a simplified version.
I have a ZS180, it's a cracking engine. Goes well and sounds lovely. Doing the belts was a pretty horrible job, but would be infinitely easier
with the engine out of the car.
The plastic inlet manifolds and the motors that drive the internal valves are probably the weakest aspect as BT says. New manifolds cost a fortune
and as they are (plastic) welded together they are very difficult to take apart and fix (but not impossible apparently).
These don't have any of the head gasket issues that the 4 cylinder engines suffered from*, they have wet liners but a solid deck unlike the very
open deck on the K4.
*Apart from the early versions fitted to the Rover 800, these were pretty terrible.
Cheers guys.
I've found a reference on the internet suggesting that the engine is 155kg fully dressed. Does that sound about right!?
[Edited on 19/12/11 by scootz]
Yep sounds about right 1400 k i belive is around 100kg
I also have a 180 as my tin top. Cheap to get 200bhp very dear to get more.
Have a look on you tube for a kv6 hill climb car. That sould get you exited.
Here you go Scootz...
Link thingy
Cheers Mike... unfortunately the YouTube links in that thread are now 'private' 
QED did a fair bit of the hillclimb developmements http://qedmotorsport.co.uk/qed-shop
Tom New of New Techniques, has fitted them to his own and customers race cars.
Graeme Wight Junior of GW Racing has fitted them to westfields/Dax 7 types.
Uber light, about 90kg all up from memory. as has been said, not really open to abuse by muppets, but a cracking engine, i always thought it would be
great with a low pressure pair of turbos or a blower?
KV6...Lovely engines...not as flimsy as the inline 4...my Dad's is (I think) just over 150k with no issues whatsoever so far....
Make sure you get one from a ZT or 75; the version that was in the runout 800s is allegedly worse for reliability than the 4 pot...

Whats your plan Scott ? Most people who want big power out of these ditch the kv6 and fit a turbo four pot.

whilst the kV6 wont give the power necessarily of a turbo 4 pot (and im a big fan of turbo 4 pots!! ), its shorter, much much lighter than an iron
block trubo 4 pot, doesnt need a honking great heavy turbo manifold, turbo, intercooler, is much easier to 'package' as they say too. Gives
nice progressive power delivery over a wider rpm range, as opposed to near vertical torque curve when a turbo 4 pot comes on boost, for 2k-3k power
band if you are very lucky, so the delivery is much more suited to a very lightweight car. In hillclimb circles, putting the power down is much more
important than pub numbers as is the lack of weight. On paper the blown 4 pot wins with the numbers, but on the clock given the same peak hp figure a
V6 pwer delivery would be long gone imho, especially as its liklely to be 50-100kg lighter all up (all turbo gubbins included).
Ive seen plenty of cossie powered 7 types struggle, sledgehammer and walnut come to mind. Great fun on the road or trackday where the stop watch isnt
king though.

I love the engine. At the moment the zs is at rock bottom with 01 an 02 mk1's selling for sub £500 with an mot and a face lift mk 2 on an 05
can be had for £1500 Cheers guys... I hadn't realised that whole Rover / MG cars were so bloomin cheap (although I think the missus would kill me if she had to put up with a car-carcass lying around waiting for the bits to sell).
2003 MG ZS + 180, 2.5 V6 Silver | eBay
low mile for age.
2004 MG ZS 180 BLACK SALOON 54 PLATE | eBay
This one would have easy broken for a profit and a free engine.
I passed on an 02 in the summer for £300 They make great track day cars.

I've sold the RV8 and auto-box out of the F27 and want to rebuild it with a lightweight V6.
I was going to put a 350Z engine / box in there, but there are two drawbacks... firstly, it's a 240kg combo (a LOT of that is the gearbox!) and secondly, the big power (300bhp) would mean having to spend serious cash on upgrading the rear axle (Cortina).
I then looked at the Alfa V6's and despite the most glorious sound, it turns out that they're even heavier buggers and there's no quick-fix rwd gearbox solution. So more £££££'s!
The last two on the list were KL-DE v KV6.
I couldn't find anything untoward about the KL-DE, but found that the KV6 trumped it in just about everything but physical size. Furthermore, the KV6 can bolt right up to a Type 9 using an off-the-shelf bellhousing.
So I'm thinking of a KV6 on an aftermarket ECU and Triumph bike TB's, and a Type 9 with alloy case. SHOULD see 220bhp, an all-in drivetrain weight of 140-ish kg, sensible financial outlay and the rear axle will only need 'breathed' on.
That's as far as the plan goes today... expect it to change full circle by the end of the week!
