Turbo for a 1 HZ

Before you let out a big groan!!! This question is (I think) a bit different:
My thoughts have been turning to more power, and I am far from convinced that I should do it... but maybe I get a christmas bonus!!

Anyway I have done loads of pricing and looking at (pretty much exclusively Ozzy) 1HZ turbo kits. But then I threw it to one of our suppliers - in Holland, and got back the following after some questions about where the kit came from:

"1) The brand name is Toyota, The kits will be build with original Toyota Parts, (no Australian parts will be used) The offered turbo is a low pressure turbo, the turbo boost isn’t more than 0,55 up to 0,6 bar. It will give an extra 35 HP and additional Torque of 30 – 35%,

2) Without fitting the boost compensator the engine will not run 100% when the turbo isn’t switched on (below 1500-1800 rpm).. The turbo is providing more air/oxygen to the engine, this will gain more power but only when the engine receives more fuel as well. The fuel pump must be adjusted to the need of the turbo. A standard fuel pump is providing more fuel on total the rpm range, but you only need more fuel when the turbo is switched on. Without the boost compensator, the result is incomplete combustion (black exhaust gasses) below 1500-1800rpm.

I have translated this from Dutch, hopefully it is understandable."


Now I am well aware of the risks of turboing etc and for sure would fit a pyrometer and a boost guage. But I have never heard of a 1HZ toyota based turbo kit - can anyone shed any light?
