You can get the boost compensator assy from the early hdt pump new from Toyota here for ~$180 us. PartSouq Auto Parts Around the World
I don't think the hz pump was ever manufactured with a boost compensator, but early hd is pretty much just a tdi hz and this part should fit. I can't confirm if you only need that or if other modifications to the pump are needed. AlbertoSD built a factory turbo 1hz in his build thread Builds - 1985 BJ70 Story and Modifications and the ip work is covered somewhere toward 75%. You can also probably find a cheaper price if you're willing to research Toyota/denso part number cross references and buy from a denso vendor instead.
