xflow 1100>1300

[alesh]

Hi.
Please don’t judge me if I ask a strange question.


I have an xflow 1100, I would like to increase the capacity to 1300. What all needs to be replaced?
Thanks

Well I might be wrong, but I think it's a straight swap.

1100 out 1300 in, or do you mean re-work the 1100 to make it a 1300?

you can actually just swap in the 1300 crank from memory and get a hc 1300 from your 1100.

Sounds like a good plan.

May need rods too but I can’t remember the numbers

I have one engine that is 1100. I would like to convert to 1300.

Importing the whole engine from England to Slovenia would be a big expense.

You will need the 1300 63mm crankshaft and the 1300 rods, which are shorter than the 1100 rods, although not quite as strong. If you're bores and pistons are in good order, just leave them there. You will gain a useful compression increase by using the 1100 pistons in a 1300. Pistons attach with circlips, so it's an incredibly easy process. New main and big end bearings will be needed, unless the ones that are in the 1300 are included and healthy, and then you might get away with it.
All in all a very easy process.

Thanks for the information.
But first I have to open the engine and then buy crankshaft and rods....somewhere

[alladdin]

there were some on FB - needed a regrind tho i think

[alesh]

I thought a little.
It would probably be better if I bought the whole 1600 engine.
Does anyone sell it, at a good price

1600 ? Or 1300 ? Try ebay - Germany or another EU country. 1300 engines should be cheap.

I`ve got a brand new 1300 LC engine, sitting in a ford box. Engine is from 1977 iirc.
If you can organise collection in germany you can buy it from me.

I don’t have a lot of knowledge about Crossflow engines but I do know that the bore is the same for 1100, 1300, and 1600 so stroke for each is longer and to accommodate the longer stroke the blocks are taller much like the Duratec engines.
this is where my knowledge is sketchy but pistons from a smaller capacity engine if they are put into lager capacity engine increase compression.

Of course the easy way is to just fit a 1300 engine which you would have to buy for the crank…

I’ll leave it there as I have run out of knowledge
