Me Dave? Or another Dave?
I'm probably not your man to talk to about the right turbo, Pete (TB205) seems to know a few things if you want to go into the realm of a VNT as he ran a 200bhp VNT HDi, ooooor, Ruan or someone if you want to go for an boost actuated turbo that is also modern, and fits easily
I've always been one for doing jobs right, and I wouldn't buy anything that wasn't either recon with warranty or new. Thus for me the next step after FMIC would be a hybridised rebuilt k03 and I'm certain with that 180bhp would be possible. Possibly even 190bhp with the very best exhaust (just something that looks like a drainpipe, not something naff with kinky bends) and a fit engine generally.
Torque isn't as high as it could be, possibly it's a touch lower at lower rpm, but that makes for an easier life on the HP pump, so you can probably run standard everything else and get good torque and good power!
Beyond that I'd go VNT like Pete did, but to really make the most of that it's an upgrade pump (make sure it's recon or very good, otherwise it's no better than a good standard one), an upgraded rail sensor, an upgraded clutch to take the big low-end torque, alternate setup for ECU/solenoids to run VNT, a VNT turbo (again, make sure it's very good or recon to assure it will work as expected), and so on... you might even want to re-tip injectors to make life easy at around 205-210bhp.
That is my 2 pence any way.
Going big on torque is why soooo many cars on here both need fancy clutches and also suffer with p0230. Pump is spinning slowly and making BIG injections through small injectors so you need BIG rail pressure too... arghhhh!
Better as a next-step after FMIC to rev more (not 5000rpm, more like making peak power at 4000rpm rather than 3250rpm) with a bigger turbo, retain moderate mid-range torque.
Then if your wallet is liking the idea of a step up from 250lbft/185bhp you can sink £1500 more for turbo, mapping, solenoids, clutch, injectors, pump, rail sensor etc to get another 20bhp and 70lbft.
No doubt Pete's car will have been rather amazing, but he spent a lot of time getting it perfect, and that takes money too.
From experience I can appreciate both ends of the spectrum. Any HDi with FMIC is faster than it needs to be, so beyond a certain point it becomes a personal preference rather than right or wrong.
All those nutters with 1.9Td's that rev hard and make mega power can't be wrong and represent one end of the spectrum, while those with VAG's that make peak power from 2500rpm to 5000rpm that are devastatingly fast, but about as much fun as a train to drive (imo), clearly have something they like!
