MG MGF Technical - V6 in Total MG

I told you

I told you!!

V6 fitted to which car?

In an MGF Stephane :o)

Neil, we know! LOL

I still remain to be convinced that this conversion is a great idea. The KV6 weighs 50kg more than the 1.8 litre K-series that we all know and love. The engine is also a comfortable 70mm taller - which has an impact on the height of the centre of gravity for this lump.

The centre of gravity is a core consideration here for the handling of the car. Remember too that the V-configuration of the engine means that more of its mass will be higher on the V6 than on the corresponding 4 cylinder... Under 1G braking and cornering, of every 10mm the C of G is raised, the weight transfer moves by 10mm - or put another way, a 5% further weight transfer under braking or a 10% further weight transfer under cornering for a car of the MGF's size...

The car's suspension will need to be substantially stiffened to cope with this mass change ... at least for spirited handling on track.

I think that the reviewer's take on the car was just right: if you want a "Grand Tourer" then this KV6 powered MGF is probably just the thing. Lovely, relaxed engine, with plenty of character. Just don't expect a high performance sports car... But I'd be happy to be proven wrong.

So where is the first 1.8T transplant?

Purely as a matter of interest, what power and torque does the KV6 deliver?

And does it get HGF? :-)

I know that Kingsley is actively considering this option at the moment Will - and the engine and turbo should fit :o)

>> Purely as a matter of interest, what power and torque does the KV6 deliver?

LOL - no HGF Jamie! Although that is in FWD applications...

Regarding the power and torque characteristics compared to the TF135... well check this out: http://www.mgf.ultimatemg.com/group2/engines/images/KV6_v_K16_power.jpg

The KV6 is a very attractive engine - monster torque and power, straight out of the box.

I just feel that the MGF isn't necessarily the best recipient for this powerplant, but since I haven't driven a car so equipped, I am hardly in the best position to give an authoritative opinion on this :o/

Worse - it could get two at the same time!

Please remember that the V6 MGF is made by a bloke in a garage in Cleckheaton not in an R&D facility in Longbridge. So he is doing very well

If MGR were serious they could produce a TFV6 very easily. Yeah Rob I understand your comments about the C of G for the V6 in an F. It is heavier and higher. it all depends on placement and I fear that the KV6 in the car described is placed where it can fit, rather more than where it should be.

Personally however I do beleive that it would be very possible to engineer out the problems as envisaged
Mind you, an HGF might mean an engine out job!!
and with it nicely cooking in the confines of a tight engine bay....arrrrrrrgggg!!!

>>Please remember that the V6 MGF is made by a bloke in a garage in Cleckheaton not in an R&D facility in Longbridge.

IMO thats a bad thing! Who knows what 'issues' this chap may have overlooked producing this car. At least if the like of MS or B&G had made the car you would have some confidence that it had been engineered properly, but personally I don't with this bloke.

>>If MGR were serious they could produce a TFV6 very easily

You seem to forget that MGR tried that idea, and rapidly dropped it. What you should be asking is why did MGR drop the idea? It could be because of the reasons Rob described, or it could be for numerous others reasons (fuel tank relocation/MPG/Cost etc). But at the end of the day if MGR were not happy to do it, there must be some good reasons.

You could possibly engineer some of the problems out, or fill the car with electonics to stop peeps crashing it like some manufacturers do (& making it very bland drive at the same time) but it all requires money. MGR could 'easily' squeeze 20-30 BHP more out of the 4 pot if they really wanted too.

But then, MGR never put a TC or SC on a roadgoing (production)car. Others have. Why?

Hi guys,

just bought a second hand 1999 MGF. Drives fine but has a ticking noise in the front left. I figered out it should be at the brakes or the suspension. I tried to remove the wheels to take a look but it seems that there is some kind of klip in the form of a bolt above the real bolt and I can't find a way to get it of. Can someone give me a hint?
Tomas

I think you refer to the chrome caps fitted over the locking wheel nut, There is one on each wheel. You should have been given a plastic removal tool which is used to remove this cap. Then you need to use an adapter to remove the locking wheel nut, this also should have come with the car.

good luck

V6 in an MGF, it was only a matter of time - we've been talking about it for ages on here.

I came close to doing it myself a while ago, got as far as working out how it would be done, locations of bits and pieces etc (i had planned on a Porsche slab tank under the front bonnet though, having owned 2 KV6 powered cars the last thing you want is to reduce the size of the petrol tank!), but time and money didn't allow.

The other reason i didn't do it was although the hike in torque would have been usefull (and very welcome), +30bhp just wasn't worth the effort.

To make this a viable proposition i feel you need at least 250bhp from the engine and this means spending a lot of money with RSM or similar on top of the purchase of the engine and the installation costs. Afterall, you can get 160bhp from a stock TF or a Trophy 160, +30bhp isn't really all that much in comparison.

The extra torque would be very welcome, and this is why i ummed and ahhed about it for so long, but ultimately it was just too much work, money and hassle for too little gain IMO.

I'm sure the V6 F is superb fun to drive, goes like stink and it looks like it's been done very well, and a couple of years ago i would have been the first person to sign up for a conversion like this.

I wish him the best of luck and hope he has a number of clients - who knows i may still be one of them one day - the idea still appeals (but it is a decision made with the heart not the head).
