Is it about trying to keep low down torque, rather than all out power?
Also why a fixed geometry turbo rather than variable.

Thanks

my mate has the GCB 22 in his defender and it’s insane with power, these have the same oil and drain locations like the factory turbo so it’s easy to install and can run very high boost and power at a really low cost $1100 vs $3500-$6400 for a vnt

I chose this on my daily as I try 3 different vnts and it’s very hard to setup correctly with low down power and power up top, had one vnt wastegate break on me with was disappointing and another vnt had been messed around with the settings and drove like rubbish

vnts are harder to dial in to what you want, my circumstances are much different to most

plus fix geometry is easy to setup and tune for the most part
