After a bit on looking about on the net including andy forrest performance web site it looks like the standard td05 turbo should be good for 340 to 350 bhp but what boost pressure would be safe for the unit ?
Please correct me if I am wrong as I can only go of what I car read on the net and on here

Well from a bit of study of a compressor map for it, 1.2 to 1.4 bar looks like a safe working range on a 2.0 litre. It'll actually run up to 1.8 bar I think, but above 1.4 bar it's not really making any worthwhile power there. On a 2.5 litre I think you'd find it wouldn't be big enough to work well without 'choking' - running out of puff in other words. But I may be wrong. Others have plenty of practical experience on these - I'm just looking at the numbers.

I'm running a TD05 on a 2.5 litre, approx 330 of each.
The same car when a 2.0 was boosting to 1.4 bar and naturally tailing to 1.2.
Now on the the 2.5 its boosting to 1.2 and tailing back to 1.0 IIRC, due to the 25% extra capacity.
On the remap my IDC's went up from 90% on the 2.0 to 95% on the 2.5.
Power wise I don't think its much different from the 2.0 (its near the top of what the TD05 can do anyway) but it spools up quicker and has more torque on the 2.5

I have an FE TD05-16G on my 2.5 conversion. With Gruppe-s headers, 440cc injectors at a raised fuel pressure and running 1.45 bar boost my car made 341 bhp at 5550 rpm and 357lbs/ft torque at around 4500 rpm, torque curve was quite flat between 3000 and 4500 rpm then starts to drop of.
