didn't realise you was running that kind of power my misses drives mine so it's staying at 198.8bhp other wise it will end up in a ditch.
With that kind of power i think its hobsons choice as you will go through t3's like there no tomorrow, as it happens i still have the t34 and if your interested reply back. If your running a t34 you will need to make up a spacer plate 12mm to go between the manifold and the turbo to clear the manifold, or www.autospeacalsits.co.uk do a tubular manifold and the turbo bolts straight to it with no spacer plate it also helps with the lag. The other problem is space, fitting it in without having to fit a new radiator ever 3 miles because your acuator has gone through your radiator yet again!!! i went through 3 rads but mine is a mark 5 cab so there is less space in mine for the rad and cooler.
