x/flow to pre-x/flow conversion - HOW?

[keeh]

Howdo.

I'm looking into a pre x/flow conversion on my 1300 x/flow.

I have no clue on what combination of parts to use to keep a reasonable compression ratio. I am aware that there are 1300 pre x/flow engines somewhere that had been used in cortinas, anybody got the internals?

 

i have some 1100 rods which work out 4.85mm longer than my 1300 rods. I want to try do this without having any machining done on my block to keep costs down, i'm on a tight budget. I'll need around 33cc's of combustion chamber to keep around 11.1 CR with a 1330 engine.

 

any help will be appreciated, I know of a 1500gt head nearby and also been offered a 997 head off here.

Anybody confirm for me?

 

I think, using 1100 rods with pre x/flow pistons will do it, but the pistons may need shaving a couple of mm to fit perfect.

Im buying a 1500gt head tomorrow, owner thinks the chambers are around 30+cc but can't check as there are no valves.

 

If the pre x/flow pistons are 41.65mm height against the x/flow 44.75 then the 1100 rods will make the difference up plus more which is why the pistons will need shaving.

will give me a nice light piston and as such a nice revvy engine

 

if anybody can help me out here

Sounds like you know what you doing to me
