Can I Fit A 1300GT Head To My 1100 Crossflow Engine?????

[72mk1escort]

Right i am after fitting 1300GT Pistons,Connecting Rods,1300GT Head Onto My Current Engine (as i know its a good 38,000 mile block etc ). I then will be fitting a twin choke webber,KnN Filter,4 branch manifold and escort sport exhaust system (standard type) so basically i am making it 1300GT spec.

 

Can this be done are am i being silly

I think the 1300Gt head will fit BUT if you put 1300GT pistons in you will not increase the capacity but you will reduce the compression (less power). common misconception.

 

The crossflows share the same bOre size so if you want to convert to 1300cc you need to change the crank as it is a longer throw and that is where the capacity increase comes from.

 

You'e best off just buying a good 1300gt, escort-tec does them for £50

just whack a 1300 in it.

[hotrodholty]

if your gonnna puta 1300 in you might aswell put a 1600 in and just tell everyone (insurance)its a 1300, 99% of people wont tell the difference between 1100, 1300 and 1600s

[bortaf]

At least the 1100 and 1300 share the same block, the 1600 block is taller and stands out a mile and you'll basicly be driving with no insurance!

better not hit me in an uninsured car

 

And i can guarentee a copper or insurance surveyor WON'T be one of the 99% who can't tell the difference

i always thought the blocks where the same and the 1600 was just a bored out 1300 block, and the 1300 was a stroked 1100

when i changed mine from an 1100 to a 1600 i didnt notice any big differneces (mine is insured as a 1600 though).

Right this can be done then could someone please write me a list of the bits i will be needing to convert my 1100 engine into a 1300GT.

 

Cheers

you would be surprised i know a local racing engine builder who is an insurance surveyor no fooling him

If the blocks are the same you'll need all the above plus a 1300 crank

 

You might be able to leave the 1100 pistons in, see which give better c/r

[petrolhead]

to convert a 1100 to a 1300GT you need to swap over nearly all the moving parts. Crank, conrods, 1.1 pistons could stay to raise CR and head. So it goes back to my first statement: why not just buy a good 1300GT for £50?

 

1600GT block is an inch taller, it will fit where a 1300GT goes. 1.1, 1.3 &1.6 share the same bore size.

 

Any half-serious individual could identify the engines by doing 10mins of research on the internet just from raising the bonnet. The amount it costs to send an insurance inspector out to a crash site, you can bet that he/she will be more than half-serious. It's not a risk worth taking in my opinion.

damn you and your fast typing Fiesta Steve

[Fiesta Steve]

I'll forgive your slow typing as you gave a more detailed answer

 

[72mk1escort]

Im not trying to hide it from the insurance company i just thought it would be easier to keep my 1100 block cause i know its a good un

 

Thanks for all of the info

 

But what does CR stand for

[escortmad79]

Instead of wasting your money converting an 1100 to a 1300 why not just buy & fit a 1300?

 

They're a lot cheaper than 1600s as they're not as popular

Its hard to find a 1300GT that you know the history etc of and really i would want to hear/see an engine run before i bothered to fit it into my own car

[72mk1escort]

"Crank, conrods, 1.1 pistons could stay to raise CR and head"

 

What does CR stand for?

[Fiesta Steve]

Compression Ratio

Compression Ratio

 

Makes sense now thanks

If i Fit a 1300GT/Sport Engine,a twin choke webber,KnN Filter,4 branch manifold and escort sport exhaust system (standard type) so basically i am making it 1300GT spec.

 

If i do all of the above how much power (roughly) will i be putting out?

 

Also will my standard gearbox,propshaft and axel put up with the extra power?

[petrolhead]

I would say that if you get 70bhp on a used engine with those mods that would be good.

 

If you took the time to keep the 1.1 pistons to raise the CR and changed the cam to a BCF2 (fast road) and a bit of DIY port matching you might break 80bhp. Doesn't sound alot but they still go well in an OSF

[petrolhead]

That power won't even bother the standard gearbox, prop or axle. If it does then the part was already on its way out

[72mk1escort]

Thanks Alot Mate

 

Also what is port matching

[petrolhead]

Difficult to explain but basically the holes on your intake and exhaust manifolds never quite match up to the ports in the cylinder head. Port matching essentaily is getting a tracing of your cylinder head ports, holding it up to your manifolds and grinding away to enlarge the holes to match perfectly.

 

If you do it properly, the air fuel has a lovely smooth flow straight into the cylinder without any obstructing lips or ridges. Worth one or two horses, but every little counts!
