E16SE head on 13S block + T40's = which ignition system?

[_Jake]

evening all as some may know im building a 1.3

Spec will end up something like

13S block +20thou pistons
E16SE head +1mm Valves
Kent AST2 cam
Twin Dellortos
Matched Manifolds
etc etc

now im a bit confused as to what distributor/coil i'd use? would i use the the standard 1.3 stuff? Or the dizzy off a GTE/GSI? i have a full ignition system system off a 14NV too if i could nick parts off that? Any help appreciated :)

EDIT: before anyone says use the search, i have done but all i can find is 1300 heads on 1600 blocks lol
Oh and the car its going in has a 1.2 carb Loom in it and i dont really want to chop it about too much!

std 1200/1300 stuff is best... the e16se is peg drive & it is too complicated to modify the ignition ecu, whereas the 1300 delco is slot drive & as long as the advance diaphragm is ok & the bob weights aren't jangling about, it will be fine, but has the ast2 got a slot or a peg?

also if you haven't bought the pistons yet, get some 1200st std or oversize ones, and bore it out to suit..

1400-1450cc is then doable and extra cc is the cheapest tuning mod there is

Red cap 1.4 carb dizzy +coil etc. happy days.

Ime the aftermarket cams have both drive types.

[mowgli]

i have actually got a proper early 1300 bosch dizzy with points & a spring loaded rotor arm rev limiter....

you would be better off with a 1.4mpi head as it wont drop the compression as much. most aftermarket cams have both drive mowgli, i believe the 1.4sr ignition set up is regarded as the best

[mowgli]

with 1200 pistons with unmachined crowns & the e16se head, it would be a pretty good match

[burgo]

have you ever measured the combustion chamber of the 1.6's? they are huge. im sure i worked out it would give 8:1 on a 1.2 bottom end

[mowgli]

i've got a spare one out in the shed, i'll have a play in daylight.

i did work out that a 1300 crank & 1200 pistons with no machined crowns on a std 1200/1300 head would give over 11:1cr

[Stuart]

Iirc las time I measured a 1600 head it was 38cc..... I could be very wrong lol

[Edd]

What would the cr be if your put a 1600 head on a standard 1300 bottom end ?

[mowgli]

not great. but probably ace for a turbo...

[Edd]

Thats my thinking

I already have some low comp 1300 pistons but in a bottom end that needs rebuild

If I could dump a 1600 head on the fresh lump already in I would save time and cash

any guess to what they cr might be ?

[Stuart]

Measure and work it out.

[Edd]

And how do i do that ? :)

[mowgli]

you get a sheet of perspex, some drills & some threaded rod, then acquire an accurate syringe... (ask a farmer)

you drill the perspex to match the head bolts, & then put in 2 small holes in the middle (one for filling, one for air to escape).

bolt the perspex to the head, ensure the plug is in. then using the syringe measure in cooking oil till it is filled. you now have the head volume. in cc (same as ml)

you do the same for the bore with the piston at tdc.

you then measure the thickness of the old head gasket, & the diameter of it in cm. then divide the diameter by 2. this is the radius (r) then to get the volume of the gasket it is r2x 3.14159 x the thickness (in cm)

add all 3 you get the unswept volume.

then you need to work out the swept volume. this is bore diameter(always in cm)/2 = r. then r2 x 3.14159 x stroke (in cm)

then you add the swept volume & the unswept volume = total volume

then divide the total volume by the unswept volume.

this figure is the cr

[Stuart]

There is a calculator in m sig link o put the numbers in and get the cr lol

Ive considered doing that but ive allready got the oversize pistons and would rather use new than the old ones out of the 1.2 ive got at the moment

Any reason for 1.4 stuff over the 1.2/1.3 stuff in perticular?

Ive allready got the E16SE head mate, i'll just have it machined to up the cr :)

[mowgli]

You would get good money for the 1300 pistons & you can still get 1200 ones new & quite cheap.. And it will raise the cr without getting the head massively skimmed, which will then need a vernier pulley to attempt to get the cam timing back in order.

Purely base on experience the 1.4carb ign setup is tried and tested for the two best amateur 1.6 builds I've seen/used.

Cant see how having the head skimmed would alter the timing at all? the valves are just lower down then?

Nice one thats what i shall be using then, cheers :)
