is this a c14se head

[youngcorsakeenan]

I think i have found an alternative to the c14se head(I may be wrong). For those of you that dont know Daewoo are owned by GM, GM let them use there engines design but they were produced using Daewoo(sh!t) materials. I have an old Daewoo lanos 1.4 mpi engine lying around so I took of the head to see is it the same as the opel/vauxhall C14SE mpi i have nothing to compare it to. I am hoping someone will be able to tell me if these heads are the same.

it has been confirmed that these heads are the same apart from the valves being dished slightly on the daewoo head, therefore lowering the C.R slightly so it will need a good skim if i want to put it on my 1300 ohc block.

Which would be the best/cheapest cam for fast road use kent AST2 or piper BP270? I will be using the 1300 cam box and dizzy, would the 1300's origional pulleys and timing setup be ok with the different head?

[AlexW]

Just to double check, the inlet ports are round? If so they will be based on the C14/16SE

[youngcorsakeenan]

yes the inlet ports are round, has anybody put a c14se head on a 1300 block?, how does it work out?

[Balley]

It says on it, under the cam pulley (above the thermostat I think):D

should be stamped C14se



*****Sorry Miss read am I bad :[*****

[youngcorsakeenan]

sorry mate i should have picked a better title:roll:

[comptoncj]

Edit. think the combustion chamber is shallower than on mine . :)

[Stuart]

measure the head volume and calculate the compression ratio.

you took pics of the inlet ports, would have saved measurements and all that gayness

[youngcorsakeenan]

I'l measure the conbustion chamber volume after x-mas, the fact that the chamber is filthy might make it appear deeper;)
Would anyone know what the volume should be for a C14SE.

[Stuart]

in the region of 38 or 55cc. I cant remember exactly as it was a while ago that I measured one lol

[youngcorsakeenan]

Thanks mate:thumb:

Does anyone know how the timing will fair out on a 1300 block, it my biggest worry:confused:

[Stuart]

it will be fine

[youngcorsakeenan]

sound thanks lads for all the help,
She should move fairly quikly, for those that dont know this engine will be going in my corsa which will be done up as a corsa A gt replica
The spec will be(hopefully ;) )
-standard 1300 block
-daewoo head (very similar to C14SE)
-Twin 40s with this manifold http://www.dellorto.co.uk/merchandise/products_details.asp?PartNo=M4563&CategoryID=8&PartsectionID=46
-cam is undecided either piper bp270 or kent ast2(depending on people opinions)
-performance exhaust manifold also undecided

I'm aiming for around 90-110 bhp

the daewoo engines were made by holden and gm uses a global spec, so it will be pretty well identical, but i think its from a 75hp 1500cc engine. measure the cc of the chambers, and see what a std 1300 one is in comparison

[youngcorsakeenan]

no mate this is defo from a 1.4 mpi as we changed the engine, but i'l measure the cc of the chambers

[burgo]

i know that bolting a 14se head on a 1.2st lowers the compression to 8:1. im also fairly sure the 1.2 and 1.3 combustion chambers are fairly the same

[mowgli]

the 1200 & 1300 heads are identical

[burgo]

the 1200 & 1300 heads are identical

theres your answer then. you would need to skim fook loads off the c14se head to get the compression ratio back up which would lead you into valve clearence problems

[youngcorsakeenan]

the combustion chamber took 37ml of oil. i'm not sure what that is in cc's

37cc

[youngcorsakeenan]

haha i knew that:p

[youngcorsakeenan]

i havent collected the 1300 yet so i cant measure the chamber volume of it, does anyone know the volume of the 1300 chamber. if i knew the chamber volume of a 1300 i would be able to calculate what the C.R would be with the daewoo head on the 1300 block;)

errrr??

[stafford]

If it helps ive pulled a 1.4 spi (little square ports) head off a 1.3 sr bottom end and that worked with the 1.3 belt setup, thin belt and very small teeth, i dont trust that setup personally.

[youngcorsakeenan]

**** so id be better of using an astra 1.4 block(mk3 8v)?:mad: i didnt want to go over 1300cc ahwell

[youngcorsakeenan]

are all opel/vaux 1.4 8v blocks/cranks/rods/pistons the same. iv measured the chamber volume of the 1.4 spi head(roughly) is spilled some and got pissed of so i left it till tommorrowlol it took roughly 20cc which i preasume is wrong?????

I know for a fact that the pistons are different between the daewoo and the vaux 14NV spi as they look very diferent but i dont know what the diference would be in volume.
The C.R's are as follows
daewoo 1.4: 9.5:1
vaux 1.4 spi: 9.4:1
vaux 1.4 mpi: 10.1
These are taken from autodata
So IF(?) the mpi and daewoo heads are the same AND the spi and mpi pistons are the same(?) then i should be lookin at a C.R of 10.1 maybe more with a bit of skimming

So does anyone know the chamber volume of a C14SE MPI?????

[grasser26]

Hi-I dunno the cc of a se head but a nv head is 22cc ish as you found out-if you check on here in stuart's signature there's a link to a calculator for cr.I had my head skimmed 1mm and it gives a 5cc drop-normally the total volume for a 1.4 nv is 41cc-this should bring the cr up to 10.5:1.

[youngcorsakeenan]

thanks mate that roughly what the daewoo head is so should be good c.r. the chamber alone takes 37cc so should be ok.thanks
