I reckon go for it for one particular setup high comp and low boost.
Just set the psi low and use high comp.

Problem is if you are going draw through the Rex turbo is BBearing?
that means smoke when your on boost.

Theres a guy in adelaide who has a website somewhere as he imports
kei cars and parts and he has an answer to using BB with drawthrough
by using some kind of valves or flaps to avoid this.
Hes done it with the same turbo topgear used and this guy sells them
also for about 200 off the subaru liberty twin turbo. Give him a call
and he should tell you what he does, he told me but I forgot.

Some Honda guys are using high comp with big muther snails on low boost.
