Read the ad. more carefully! It says the gains are for a M52B28 (or M52B23), fitted with a M50B25 inlet manifold, as well as the TB. The standard B28 manifold strangles the engine to the point that it gives no more power than the 2.5, although with greater torque. Fitting the 2.5 manifold unleashes the potential of the extra 300cc, so considerable gains are possible, although 30 - 40 bhp extra is probably stretching the truth a little, with no other mods.

i read it right the first time mr moore
thats a good gain if you have a m52 under the bonnet
i would have thought that sort of gain would be quite difficult on a NA engine thats all lol
