FRM liners is the problem.
http://www.hondatuningmagazine.com/t...da_frm_liners/
When rebuilding a F20C most places/people fit steels liners. You can't hone or replace the FRM, it's a thin layer of special material that is set during the casting process.
Unless this company bores out the existing cylinders and fits steel lines... with appropriate rings and pistons then it's not a proper rebuild.

You CAN hone them and fit pistons and rings up to 0.25mm oversize according to the Honda manual, they also explain in detail how it is done. I can't understand why so many people on here think it's game over when an engine is damaged.

The FRM is extremely hard and it's the rings that are the wear item hence you simply replace them and off you go - no need to rehone unless you have damaged bores.

The manual also states there should be a 60degree crosshatch in the cylinder walls. To me that is not like glass, however I haven't ever had the experience of doing one, maybe when using the recommended fine stones you can't actually see the crosshatching.

So decent second hand engine as is: about £2200
Second hand engine with a load of work done to it: about £2200
If what they're saying is true, what's in it for them?

My bad, I must have gotten confused 
Service manual info:
Reboring limit: 0.25mm {0.01in.} max
Hone the cylinders using the following equipment, materials and methods:
. Use only a rigid hone.
. Honing stones:GC-600-J or finer stones for non ferrous metals
. Pressure:200- 300kPa(2 3 kgf/cm',28-43psi)
. Honing rpm:45-50
. Honing thickness;Less than 0.02mm (0.0008in.)
Do not hone more than 20c ycles,
. Honing lubricant:Oil type
. Honing pattern:60 degree cross-hatch(A)
. Hone cleaning: Clean the stones every five cycles.

you pay them 2,200 and give them a bare engine (yours) in return for a remanufactured engine....
so whats in it for them..................
2,200 - cost of shipping - labour - parts = 1500 per engine profit give or take i would say.
dont see how thier profit margins is anything to do with this though
