The guy says in his message posted above it made 408HP, which may well be true, WITH a T4, that he claims it used to have, so he needs to ammend his advert as there is a clear discrepancy with figures.

Also they are cast iron blocks, not alloy , unless he has one of the reproduction 200 blocks which I doubt!

He clearly admits from his message he dosen't know to much mechanically, to be fair to the guy.

I find it strange he has grey injectors as well with a T3.

As for the 700HP his living in dream land, quite literally, even experienced tuners have not managed to extract that sort of power and you would need to put a hell of alot of expense into it doing so. (Excluding Rods which is a little different)
