View Full Version : C14se on 40's.
as opposed to the oe injection. Discuss. Also to convet it to carbs, could i run a 1.3 head? :)
what cam so i can run a 1.3 dizzy? also carrier so i can run a mechanical pump?
ast2 cam maybe, and a 1200-1400 cam carrier. Only a guess but can't see why it wouldnt work!
wonder how well it'd run with a 1.3 carrier with cam, c1.4se head and bottom end?
all the carriers are the same in terms of fitment. i wouldnt bother with a standard cam if you are going for 40's anyway so just get hold of which ever dizzy set up you prefer. Or of course you could run it on megajolt to keep the dispak. Oh and keep the 1.4sr, tis the best one
You reckon the c14se head would work with a 1.3 cam carrier and up rated cam Luke? Think I'd probably go with a 1.3 carrier just to use the mechanical fuel pump
are you not better off with a proper facet though?
I do have a facet, but is it really needed if the sport runs ok of the oe pump?
fair point. is the sport a standard pump?

Yep just a standard pump. Might need a reg?

Standard mechanical pump will work fine without a regulator, although feel free to fit one if you wish.
Go for an uprated cam if you can, in the carb carrier. How lairy do you want it?
What ignition setup are you hoping to use?

Double post
Was just going to use the 1.3 set up?

I cant see any problems especially if you are sticking with the C14SE head (no changes in CR etc) :)
John
keep the head and bottom end
Maybe get a carbed cam carrier as it will have the hole bored out for the mechanical pump
either use the mechanical pump or a facet to supply the regulator, 3psi after that ;)
Kent AST2 is the weapon of choice for an 8V (you could goto a Piper BP300 but its a little peaky and annoying imho)
could use a 1.3 dizzy, coil and gin module but imho the red capped 1.4 Carbed setup is marginally better (again imho)
Build and rant the tits off it :)
Cheers stu, Really fancying this instead of trying to turbo it! Anyone know if you can use the Kent cams with the 1.2/3 dizzy set up though?
iirc they have 'both' dizzy fitments on the cams... but wise to check.
kents are both drives.
obviously a round port manifold is needed

yep, i currently have a 1.3 item, so will have to find a suitable one for the c14 head.
or ask a nice engineer to mill your ports round

looking at it Mike, the 1.3 port faces are already much bigger than the oe c14se ones.
oh well, you'd probably be able to sell it on for decent money & you do see them come up on the bay for the 1.6's fairly often.
ports might be bigger, but iirc the MPI valves are bigger than the carb ones.... Willing to be proved wrong though.
edit, not relevant, need to learn to read posts lol

lol wonder what gains you'd get from flowing the head and port matching the inlet?
the mpi valves are bigger. bit of port tidying up would probably get 10% more hp alone, so add the 40's, a cam, match the manifold & get them properly set up & you'd be looking at more like 30%

i have just finished my C14se on twin 40 weber carbs
i have the Kent AST2 cam and 1300 distributor altho i may yet run the dispac and some form of management
if you have any questions i may be able to help out

Any pics chap? Are you running the c14se head?
Is it worth running an adjustable pulley with the ast cam?

If you can get one cheap then yeah chuck it on, otherwise IMHO they aren't worth the rrp
Cheers Stu. :)
might have an afternoon in the garage assessing what i've got and what i don't need. Just need to find a car to put it in lol

i wouldn't bother with an adjustable pulley to be honest
:)

Normally about 20-25% on an 8v, but it obviously depends what you start with. I've seen a 70% improvement come out of a triumph head lol
Might be worth investing in doing that then whilst it's all in bits. :)
Haven't read all the details, but is it possible/worthwhile CR wise to use an E16 head?
Iirc the two mpi heads were too all intents and purposes were the same. I reckon little gain from moving to a 1600 head
My concern was more that I've got a 1600 8v in my boot and access to a head shop, that may not have been clear lol
Soooo, here's a 1.3 inlet gasket on the 1.4 mpi head.

Feasible?
Mk999999999 opinions please?

As Elgan has shown and Edd is in the process of doing it then it must be feasible. You get the best of both worlds, the larger cathedral ports of the 1.3 manifold & the bigger valves of the C14SE head.
The basic castings will more than likely be similar so I don't see any problems with material removal breaking through to anything.
That's what ive done, put gasket on, and used dremmel type tool on it
For me it means I can fit the turbo stuff using a standard 1300 bottom end

Is there a difference between the E16 & C16 heads?
edd your scum if thats going in a sport
I think there is rich, but it's small iirc. Best hold fire on the wanted ad then lol

Not here please, take it elsewhere. Back on topic!
Is there a difference between the E16 & C16 heads?
no.
can i put the spanner in the works & point out that the c14se head flows way better than the 1200/1300 heads, so having a round port must be a better shape... the cathedral shape has always confused me anyway... its not a shape that is considered good for anything other than church windows... why not chemical metal the intake? i've seen it done on a racing quad head with ridiculously good results
No chemical metal for me, would sooner fit the correct manifold.

no.
They are a different part number on EPC so there must be some differences.
probably a different supplier.
The difference is that a e16se head has a egr valve and the c16se doesn't

Thanks Edd.
What kind of an answer is that Mowgli?!? Not your usual knowledgable self!

I did a test while at Uni with access to a flow bench where I filled the bottom of a 1200 head port with plasticine.... Low valve lift was marginally worse flow but at higher lift it flowed better than std. There is a pretty comprehensive write up about the round 'straight' port idea in Vizards Ford OHC engine book.
John, just sell the 1300 manifold and buy the 1600 one... its 'only' £100 and im sure you'd get close to that for the 1300 one lol
Think i might well do that, then get the head flowed.

OEM's traditionally use a different part no. if they use a different supplier, or change a spec in some minor way...
the only possible difference between the e16 & c16 heads could be in mounting holes for sensors connected to the different efi setups & the dizzy clamp
ps. i used to make a fortune for the tractor dealership i worked for by finding out the old part no.s & checking if they still had stock at the warehouses, then try to get a stock order at a knocked down price.. we used to get cranks that retailed for £650 for around £120, then sell them to other main dealers for £250, or £500 to farmers.. and honestly, nobody else in the trade could work out what we were doing...
we once bought a pallet of turbo engine cranks with turbo spec big end shells for £90 each, took out the turbo shells & sold them for £100 a set, put std shells in the box & sold them as non turbo for £500..., or £800 for the turbo engines(with the turbo shells back in)... just cos i asked someone a quick question about an old part no.
The 1.4 heads have a smaller combustion chamber than the 1.6's therefore a 1.6 head will
Loose you power. As for the port shapes you have to remember the inlet charge moves through the port much
Like water. Therefore taking it out to cathedral shape will make bugger all difference IMO as the difference is at the bottle of the port which doesn't have a massive effect.
Having said that of course If you take a c14se head and open up just the opening of the port so that it the gets smaller you could end up with a Bernoulli effect ad as the inlet charge speeds up it should draw in more. Of course that's nice in theory but heads never do what you want them to.
Mk999999999 opinions please?
port shape looks doable but it depends on a lot more than just the entry, I'll have a look at the E16 I have if it's the same shape and see what I think, looking at that though I'd be tempted to try and keep the round port shape.
Combustion chamber size isn't a huge deal because you can always skim it down to what you need, but if the 1.4 is smaller to start with then you're less likely to run into problems with belt tensioners etc from skimming it too far.
Ok sooooo.....
I can't use the c14se cam carrier as the breather on the carrier isn't doable. Will have to re think the breather arrangement
http://i97.photobucket.com/albums/l240/tooleater16v/ca99039b.jpg
That is a 1.6 round port manifold lol
Could you not blank it off somehow ?

Think I'll just use a 1.2/3 cam carrier and redirect the breather with a 1.2/3 breather box and filter.

The Sport manifold has a convenient hole for the hose to drop through ;)
