IIRC Ruan got 245lbs-ft of torque on the k14 with an 11mm bosch....
Back in the day when there was a lot less known about the capabilities of the stock head, and that the stock turbos were massively restrictive, that was prettymuch the set-up to have.
I don't understand what you're aiming for really though... It's all well and good having a torque figure in mind, but its about the torque spread imo. You can get 240lbs-ft at 2.5k with a k03/gt15 but it'll be dead past 3k really and all your mates will laugh at your tiny manhood because you can't get past 90 at adenauer....
On the other hand, if you get a td04 or similar, you'll get much better torque nearer the top of the revs with the correct pump mods....
Also, you don't want to neccessarily be targeting a 'boost figure'. a T2 will get to 30psi. But you'd be mad to run one there really, as the heat it generates makes the charge less dense, and even with a front mount IC you'll not have the flow to get any decent power at the top end.
And though I'm not 'on the pulse' anymore with diesel tuning, IIRC there have been failures from all engines, irrespective of code; so imo the best thing is to just rag on and if it blows up, it blows up... pack a spare engine for the 'ring.
And don't expect to keep up with your mates.... I'm not being predjudice, but a '6/Type R both pull hardest at the top end, meaning they're always pulling towards max. power. A diesel is pulling away from that point past 3.5-4k without significant modification and a hooter of a turbo, so realistically your top speed will not be close to the aforementioned petrols....
