As above did they make one as standard. It's just my dad is looking in to buying a kit car which the guy is saying it cones with a 1.8 xflow standard. Which we both find strange as you only see 1.6 xflows any info would be great
Cheers

 

There is a version of the later x flow based on the 711M, called the AX made in south africa, it is basically a thicker walled block, that can be taken out easily to 1825cc, with oversize pistons, with stroking around 2000cc is available using a modified datsun crank.
On true x flow 711 blocks 1760cc(pistons only) was regarded as a safe limit, this may be what the advertiser means ?

Agree with tabetha the only x-flows i have come across are 16 bored out to 1740-1760 at a push but this is towards the xtreme end of the engine especially for drivability........this is more suited to track days than town driving.

 

ask him just that, why is it a 1800cc when they never made one,chances are they mean a pinto out of a old sierra. if insists its a x flow ask him for a spec list and post it up,we,ll have a look.

 

could be a cvh ?

 

It is possible to get 1800cc on a 711m block, but bloody expensive, not personally seen it done, but know it has been done, by stroking as well as boring.

hi folks thanks for the replys ive since brought the car and with abit of info ive found out here and there i brought it as a 1600 not an 1800 so when i do take it apart if its anything else its a bouns
thanks

 

What's the letter after the engine number 711?

I had an 1840cc crossflow. But as above, generally only up to (under) 1800cc is possible on the 711 block.
