Andy, can you confirm that the OE turbo is BB? Maybe when you get the one from Japan??
If so, why is Danwatt's and Jet's BB highflow shorter?
My highflow is very nice, the cost was $1100 + install.
Boost is the same as OE (0.8bar @ 3200rpm), but it now boosts to 1bar and ~3800rpm and holds it to redline (literally).
Don't know if it is BB or Bush, what internals were used etc etc... the workshop that installed it has "lost" the invoice which the turbo repairer needs to check their records.
(Really starting to piss me off).
Can't hear my turbo spinning when the car is shut off (but I do a cool down before shutting it off, so maybe that is why).
Will see what it can do when I get the eManage installed (probably around the same time as Jet gets his Haltech in).
