Mk1 1.2 8v e7f tuning?

[Wilko22]

Hi, im wondering if anyone can help me and knows of the differences in the energy range of engines? For example heads, manifolds, cams etc. are any of the parts swappable for more power? Also does anyone know if i swapped the engine with the newer 1.2 turbo engine, how much work would it be, is it possible atall? Any idea how it would effect insurance as it'd be the same size engine just off a newer model.. That happens to have a turbo?..

any info appreciated, not alot about for this engine..

if your going to go to all the effort of an engine swap, put an F4R in it.. seems a waste of time otherwise!

 

[Wilko22]

Weight, insurance, tax.. I would rather make the engine its got faster, if i can do it just by changing some parts off other engines, the 1.2 turbo was just an idea if i can't at the min..

 

[Jaff.]

Energy engines aren't renowned for their tuning potential tbh

 

[Wilko22]

Ino.. I cant find out any information on them, i wanted to no if any of the parts from other engines fit the e7f because thats the engine i've got in the car i've got.. Is the block the same as the 1.4? Or any parts on any engine? Some cars have the same block for the 1.4/1.6 just with different parts on them..

 

[JamesWilson]

Ive got a 1.4 ive spend a fair bit on and its tbh only a tiny little bit faster. So now I'm collecting parts for a F4R, which I should have done the first time round.

 

[Jaff.]

Just wait and save up your money for a better car. You'll regret spending so much on such a weak base

 

[Wilko22]

But thats the 1.4... If parts off the 1.4 fit on the 1.2 i can get them cheap second hand, cheaper and easier than swapping engines..

 

[Jjay]

"Yeah but that's a 1.4" so? Same principle.

Also, your doing all these mods it will make your insurance rocket anyway.. Unless your one of those not gonna declare

 

[Wilko22]

It cost me £150.. Ino i can buy another car, i dont want to buy another car, this one has had alot of money spent on it by a mate and its a shame to get rid of it, i dont want to make it the fastest car in the world, i want to keep it a 1.2 and would like to no if anyone knows if any other parts fit, if you don't thats fair enough..

 

[Jaff.]

I don't think any do. It's an old engine that isn't used or modified anymore. You have a case with 1.4-1.6 but even then its not worth it

 

[Wilko22]

its not even on the road, its just a project, i dont even know what im going todo with it yet, and same principle, different engine.. Look at vauxhall corsa b, 1.4/1.6 are the same engines, ones more restrictive, 1.2 is completely different and no parts from the 1.4/1.6 fit and i can insure it with all the mods for 1300 less than i paid on my last 1.6 with no mods, i've spent the last couple of years looking at doing things like this, im not stupid..

 

[Wilko22]

Thankyou thats what i mean

 

[Jjay]

If its not on road and don't know what your gonna do with it why not get 172 and use that as project?

 

[Wilko22]

As iv already said i got this for £150 and its had alot of money spent on it by the previous owner..

 

[Jjay]

Ok give up trying to talk sense. I'm out

 

[Wilko22]

Ok give up trying to talk sense. I'm out

Helpfull..
You can always buy a faster car, i dont want a different car, its just had the sides smoothed, headgasket done, alternator, new subframe, and other bits, if i dont modify the engine im stripping the car, which i don't want to do

 

[Jjay]

So why mess about with it if its just had all the work.. That's my point. Insure it, put it on road, drive it, save up. Get something decent

 

[Wilko22]

Because im not driving at the minute.. And iv gotto strip the engine to sort out a piston ring

 

[Wilko22]

According to ebay, the headgasket and bolts etc are the same for the 1.2/1.4 which suggests to me they have the same engine with different pistons, ports, manifolds or whatever i just wanted to know what parts were different between the 2

 

[Wilko22]

So you don't know then?..
Questions still unanswered if anyone can help..

 

[Jaff.]

You realise bolting bits on to it won't make the blindest bit of difference without sorting the managment out right?

in fact it could make it worse

 

[Wilko22]

Cant u just put a different inlet and exhaust manifold on?

 

[Jaff.]

If you can get one to fit yes but to make the most out of it you need management that understands the changes. Standard engine management doesn't have to scope to increase bhp much more than 1 or 2 just by bolting bits on

 

[Wilko22]

So do you know if the 1.4 manifolds, head, throttle body etc would fit and would i be able to use the ecu off a 1.4?

 

[Jaff.]

In that case why not buy a whole 1.4 and put that In?

thats what I'm trying to say there is no point in doing it at all. If you had a stronger base to begin with then yeah if you want

 

[Wilko22]

Wouldnt that make it more tax? And if i change everything apart from the block and head then its still freshly skimmed.. Head gasket should last longer than the second hand engines, if i do an engine swap i was thinking of the newer 1.2 turbo because its still a 1.2 and its faster than the standard 1.4..

 

[Jaff.]

Or just leave it until you can afford another car? Youre changing for change sake, you're not gaining anything

 

[Wilko22]

but surely more air+fuel in and out means its going to make a bit of a difference, or do the manifolds, throttle body and things not restrict this engine? is it just the pistons that are different between the 1.2 and 1.4?

 

[Jaff.]

Ok if you change them how do you expect the managment on there to cater for it?

 

[Wilko22]

maybe 1.4 ecu, manifolds, cams, trottle body, injectors if it needs.. not think it will work?

 

[McGherkin]

Turd, Polish, Can't, A.


Rearrange the above words into a popular phrase. Unless you're making a big leap in power (e.g. a 2.0), the costs of converting, insuring and taxing the modifications/bigger engine simply outweigh the fact you'll have slightly more power.

 

[Wilko22]

already said, insurance is still cheaper with the mods than my last 1.6 with no mods by £1300, plus i will be doing the work so no labour costs, i can get parts cheap through a friend, i don't want to know if people think i should do it or not i want to no if it can be done, whats involved, what would i gain?

 

[Yellow Dave]

If the engine has had all that work, and still needs more doesn't mean it's a good reason to keep it as its had lots of money spent on it.

Bolt all those 1.4 bits onto your 1.2 with a 1.4 ecu still won't work properly, as its still a 1.2 but throwing in the wrong air and fuel mix. It's seems you need to do a bit more research on engine management. If you're car was carb'd then you might get away with it with minor fettling.

With reference to car tax, if your car is pre 2001 engine size won't affect tax unless it's a 1.6 or more. If it's registered after 2001 tax is done on emisxsions and not engine size so may not increase.

But what are you likely to gain is maybe 5bhp and a rough running engine

I would Not Bother modding this engine tbh I now have a 1.4 16 valve used to have 1.2 16 valve and tbh there is not a massive difference. The 1.4 is quicker on the top end and above 4500 rpm But I Am sure the 1.2 16 valve I had was more torquey at low revs around town. I may have just been lucky with My 1.2 I think the way to go would be engine conversion Maybe the 1.7 volvo engine then add a Turbo. They used to do this with the Renault 5 turbos.

 

[Wilko22]

you can do it with the 1.4/1.6 corsa b engines, its restricted by the manifolds alot, you can swap the heads, everything.. if i changed the head aswell would that make it work? so the only things making it different from the 1.4 is the piston size? is all this not similar to getting it bored out abit then adding abit more air+fuel

thats what made me think of the newer 1.2 turbo, that way its still a 1.2 clio and it wouldnt be a modified engine just an engine from a newer clio that hapend to be made with a turbo.. which i have read is faster than a standard 1.4 clio engine..

So then that would make it 1400cc? So your insurance is going to insure a 1.2 made into a 1.4 by someone that isnt a reputable engine builder cheaper than just putting a 1.4 in, and also your reasoning about tax is out as you've increased engine size.

The money you spend on it will outway the extra youd pay on insuring a bigger car, as you won't be able to remap the ecu yourself to get it to run

To be honest i don't care if it will work, how much it will cost you etc. But in my opinion it is a complete and utterly waste of time, let alone waste of money and a waste of a 1.4 engine you'd be breaking to do it. Hence why probably no one else has done it and can give you a straight yes or no answer

no sorry if it wasn't clear, keep it 1171cc change everything else..
and to be honest i didnt ask if you cared if it will work i asked what parts will fit if any, what work is involved, if anyone knows, what power to expect, even though ino its not going to be a massive increase, if they don't fair enough, no need to comment..
no need for people teling me they wouldn't do it, thats not my question..
