Ah, but a monosleeve like the one above has just held together for a world record 230+mph run on the Bonneville salt flats, and who knows how many other runs it made in that engine 'til the record was finally reached. (care to share Jim?)
I'm guessing glue won't quite hold up to that standard.

In 2006 I rattled the engine hard enough to crack the plugs, but the head gasket didn't fail and the monosleeve didn't split. We also had a radiator that was too small for the additional horsepower and I boiled all the water out of the engine each run, but managed speeds over 220 mph . . . still no liner or gasket failures.
Over the years, several sleeves in this monobloc have been replaced because of corrosion . . . it's hard to imagine how quickly things rust when exposed to the Bonneville salt . . . but it's still running the original pistons that were installed for 2005.
I'm convinced it's a necessary part of the Bonneville program . . . OEM liners would not take the abuse. Is it overkill for a normally aspirated engine? Probably, but I understand the Novamotor F3 engines used them. YMMV.

The problem with stock liners is that they crack where they are thinnest, of course it could be a matter of engine power and detonation.
I have not had any problems in my own engine but I still keep the power output down below app. 300 Hp.
Last week we tested my freinds 75 he bought from Nick Humphrey, it pushed easy more than 360 Hp with out any problems, still without monosleeves, but some special made sleeves.
I still think above 350 Hp it would be a great idea with the monosleeves.
Any idea what this monosleeves cost?

Savali (Netherlands) has some 2100 monosleeves laying around, would those do, or do you need to stay below 2000cc?

Beninca in Australia also sell monosleeves to suit the Nord and TS: Special Parts
Not sure on price but not cheap by any means...
Another option is to use the Alfa 155 Q4 turbo 16V engine (really a re-badged Lancia Intergrale engine), however there is a fair bit of work as this is a transverse mounted engine.
However, the 16v head mates up to the Fiat 2L as found in the RWD 131, 132 and others with very little modification.
But of course, fitting a Fiat block with what is essentially a Lancia head is sacrilege to most Alfisti! But certainly a cheaper option for those seeking BIG HP that want to keep it Italian…
As a side note, Australia’s fastest 4cyl for a awhile was a Fiat block / Lancia 16V powered, street registered Datsun 1200 with a large TO4Z turbo that has run 7.66 down the ¼ mile

These fiat/lancia blocks require heavy modification to go over 300bhp as well. They do have 16 valves, which helps flow a lot.
