1.4sr with 1.2 head

[big gra]

im wondering if i put the head off my old 1.2 onto my 1.4 will it be better, and should i put the 1.4 cam in? cheers

[Jon_nova1]

yes and yes, get a 1.3 inlet too

[Adam]

Use a 1300 head

[Stuart]

better in what terms?..... why not be vauger :p

[big gra]

better acceleration and speed really, i have a 1.2 engine and my mate has a 1.3 engine, which is best to go for, 1.2 head or 1.3?

1.2
with the one three inlet 32 34 carb

[Jon_nova1]

both heads are the same for the 1.2 and 1.3, but to fit the 1.4 carb you'd need the 1.3 inlet

Agreed, I've got a 1400SR and put a 1300 head and inlet on it at the weekend, standard carb though, and it feels like it pulls a bit more, really do need to get rid of pieburg for the weber in my garage, but ran out of time to set it up! :( Go for the 1300 head and inlet mate ;)

[Adam]

Get the 1.3 head, the 1.2 one has a higher CR. And might push cr too high.
1.3 is tried and tested.

[big gra]

cheers people, will let you know how it goes on!

[Jon_nova1]

i had the 1.2 head on my old 1.4 carb engine and it worked fine ;)

[big gra]

if i put the 1.3 head on, will i still use a 1.4 head gasket?

[Jon_nova1]

you'll need the 1.2/1.3 head gasket set, if you buy the 1.4 head gasket set you'll have the wrong inlet manifold gasket

[big gra]

will the piston not catch the head gasket if i put a 1.2 head gasket on?

[Sirnixalot]

the 1.2 pistons are 4mm larger than the 1.3 so nope you dont have to worry about the gasket getting pinched

[big gra]

cheers guys!

[Adam]

Always use the headgasket to the block you have.
Dont use a 1.3 headgasket on a 1.4 block. Sod the inlet gasket, there only two quid buy on their own.

[coochiSR]

Why not a 1.3 HG on a 1.4 block, i did :s:s:s

[Jon_nova1]

i used a 1.2 head gasket a couple of times, according to the leaflet i got in the headgasket, the gaskets are exactly the same, it just tells you the bores are different, well gives the specifications of the engines it'll fit
