Side note, I didnt realise you owned a laith?! and was the 1.6 hdi box ma again?

Haha probably won't VNT this one. I'm not going to push it on any more power. Cheers for the reminder though
Not mine unfortunately, next door neighbour's. Old boy but happy to let me go round tinkering to turn stuff down and anything that requires 'thinking about' he takes it on. Runs a harrison, a myford and a little john along with a bridport(?) mill in his double garage. Right Aladdin's cave.
BE box IIRC

So refitted and got the car running, clutch was better but would still slip, gave it a couple hundred miles but wouldn't hold from low.
So acquired a 1.6HDi Gearbox and stuck that on along with a Solid Fly and the 215mm(?) clutch. Also changed the intercooler setup to the 1.6 method for OEMness.
With it all fitted, got the car running again and took it for a drive. Immediate improvement, also has the benefit on longer ratios so sits nicely at 70mph on the motorway.
Gearbox from 1.6 hdi 90hp or 109hp? i thought that has a different type of fitment

109hp Gearbox. Not sure on the exact gearbox code. 20DM73 seems to be familiar.
I thought it would be different but I took my 1.4 gearbox to a car breaker and offered it up to a 1.6HDi engine which it would of bolted up to. So took a gamble and fitted the 1.6 gearbox to my 1.4 which now drives spot on with the extra power.

On my 1.4 Hdi i run on Gt1544S with FMIC, ceramic paddle clutch and, with the standard turbo 98hp and 251nm...i didn't go to dyno with the new turbo setup... Now, i'm collecting info about changing the engine with 1.6 hdi...or continuing with 1.4

No real different with the solid flywheel, originally the 1.4 was solid also. up to 110 at the fly. 170lbft torque. On the stock 200mm clutch which was really on it's limit.
I have driven the 1.6, and its hellish pokey. The one I drove on a run on the M5 was on track for 70mpg. Would be quite happy to drive one. I just stuck with the 1.4 for the cheap tax and this one has been around a while so kinda grown attached.
Could push it more now but I don't need to, it drives spot on, i believe I'd need to change the rail sensor to run more pressure and then I'll be up on the limit of what the injectors can flow. So for now I'm happy with it.
Good luck with whatever you choose to do. 1.6 should be capable of good things. Steve @ HDi tuning has got some good figures out of his.
