K series engine mounts
alan87 - 7/2/12 at 06:20 PM

Hi all,

Am currently day dreaming, but have a fisher fury with 1.4 k series in.

Was out in the garage over the weekend, having a tinker and got thinking about the possibilities of changing the engine.

Does any body know if the mounts are in the same position on say a 1.8 k series as they are on the 1.4?

Thanks.

Alan

If you scan through my photo archive there are some pics of my 1.8 mountings. It may help I hope.

1.4 1.6 and 1.8 Blocks are same on post 1995 engines.

The 1.8 really isn't worth the effort because it is restricted by having the same head a valve sizes as the 1.4 it just doesn't feel as sporty as the 1.4 ans 1.6.

Check you don't have have the version of the 1.4 from some 25 models which had a restricted movement throttle butterfly for insurance group reasons if you have just swapping the throttles bodies will liberate 20+bhp.

If you want to swap the engine the 1.6 is good choice.

The power outputs are

1.4 81 or 103

1.6 112

1.8 117 in 75/ZT and Freelander higher outputs in some MG TF and 75/ZT turbo

The actual outputs varied a bit as emission standards changed.

Don't some heads have smaller inlet ports than others too?

There is the 1.8 VVC that BT hasn't mentioned though, which is ~160 bhp. The 1.8s aren't as revvy as the smaller engines, but that may not be an issue. They are also the larger valve versions.

There are slightly taller though due to the VVC mechanism on the side of the head, so ensure you have some clearance under the bonnet.

Thanks for the info gents.

So the general Consensus is that te 1.8 isn't really worth it!

Britishtrident, that's an interesting point about the butterfly valve, but the main problem ive got is that I don't know which variant of 1.4 I've got. Unfortunately there is no build history with tr car, and I can't find any serial numbers on the block to help!

Yes, the early 1.4 engines had a different head casting with more restrictive inlet ports - not really an issue on a standard engine as they still make similar power, but not a good choice for tuning.

A decently worked head (e.g. DVAPower ) with a hotter pair of cams on a 1600 bottom end is the way to go IMO.

If you can look into the end of the throttle body while operating the throttle it should be obvious; the lower power engine only opens the throttle part way.

Ancient history these days, it would have to be a very old engine (pre 1995) to have the early head.
Early engines generally had an alloy inlet manifold --- which is better than the later plastic type. The VVC manifold is similar and can be fitted to the standard head.

To all performance intents and purposes all normal K16 heads you are likely to come accross are the same, on these bigger valves are the first key to higher performance especially on the biigger capacity units. Next step is cams.

Not that any of you have but if you drove a 7 with a Kseries 1.8 Turbo engine 150hp ish and bags of torque you may think differently.

My striker currently STD wit just jenvey throttle bodies is just over 160 bhp with cat fitted, but am aiming for 200 bhp
