Looks fantastic Pedro congratulations!  however H145 4.4 gears are rare and only on wagons or vb10 not sure for H150 though maybe also wagon 1200. Otherwise a cheap AMR500 supercharger with a single Su for low down torque should do the trick  then you can sell the webers and recoup all costs.

Thanks D, got lucky and found someone who was changing the diff in their wagon, very happy with the 1500 the power and torque is exactly what i wanted and what was lacking in the old engine, the supercharger sounds good though there's no such thing as too much power. 

thats nuts well done! 4.4 are a nice unit and swear
my a10 vb10 did run the best of the lot on my daily
both traffic / hwy, so with an A15 must be a ripper!
