what power would this get

[turbojolt]

all parts will be in good working order and fully rebuilt engine

1.2 spi engine block
high lift cam kit and a reworked head
1.4sr pistons crank and rods
twin webers ( 40's)
4-2-1 exhaust manifold (wraped in heat tape)
and a good s/s exhaust system

About 150BDP (Break Donkey Power)

Definition of BDP :- Donkey power is not as powerful as Horse power and just a little bit more smelly.


Not sure but probably around the 100bhp mark.

Why not just go for a 1400 engine?

the deadly insurance

[Welsh Dan]

I'd have thought it would cost you more to declare the webers etc.. than it would to upgrade to a 1.4.

[Andy]

I have heard some say,and dont quote me on this! that its cheaper to insure a car thats been converted i.e your case a 1.2 - 1.4 rather than the 1400 car itself,that said i dont know your circumstances!

[turbojolt]

this would also give mea high compression engine is that better than a normal 1.4sr engine

[Andy]

Im not sure on that one but taken account of all costs involved id say it would be much easier and cheaper to either get a 13 or 14 sr engine,theres loads about on egay and with the money you dont spend on the head work and labour etc will go towards the slightly higher insurance premium???

[turbojolt]

yer but i dont think this kind of conversion is around as much as a 1400 swap
i think it would be somethink special some think diffrent

[Andy]

[quote=turbojolt]yer but i dont think this kind of conversion is around as much as a 1400 swap

Ya joking arent ya! you could get a 1400 engine for around ?100 plus wiring box and shafts etc off ebay,the cost of all that work and parts you say is going to be ???s

[Welsh Dan]

How old are you, with how many years NCB etc..?

I took my policy out with Flux in september on my 1.2, at the time I'd had my license for 3 years, was 21, with no NCB or accidents/penalties and it cost me around ?480.

If i fitted a 1.6 they'd charge me ?800 renewal including some business miles that I have since added to the policy (which add a static 40%), so thats around ?570ish without the business miles (which I get the company to pay for anyway).

At a rough guess, the engine work you've listed would cost around a ?1000 before the additional premium?

[Adam]

Wouldn't give much power seeing as 1.4 pistons wont fit a spi block.
Unless you've had it re-bored.

What head are you using?

i would use a 1.2 head and are you sure about the pistons not fitting as some one told me they would be a direct fit

[Adam]

Yes im sure.
1.4 pistons wont fit a 1.2i spi block. Theres about a 5mm bore size difference iirc.

1.2 carb i think they'll fit, but you wont beable use the 1.4 crank as it has a different stroke than a 1200.

[turbojolt]

so if i was to use the 1.2 carb block and 1.4 pistons and rods that should work

[Adam]

I'd just start with a 1400 block, instead of trying make a 1400cc engine up from a 1200 block :p

[Welsh Dan]

Wasn't it that the 1200 carb block combined with the 1300 crank and rods made the 1400 high compression engine?
