hi, on our 4.0 L 1uz- if we had a single turbo with a 71 mm and another at 76 mm (two different applications- NOT twin turbo)... how fast would it spool up? start to build boost and how fast would it hit full boost?

on a 3.0L 2jz-gte.. when i had the 76mm turbo, it made full boost by 4800 RPM.. (in 4th gear) so i'm curious what it would do on a 4.0L 1uz... ???

i wanted to know which application would suite me better... if i should go with the 71mm or a 76mm turbo on the 1uz...

thanks

 

It depends on your other mods as well...I mean, you can always use nitrous to spool the turbo too. I guess you kind of need to be more specific on the setup and what you're looking for

 

check out username stevechumo. I don't know what size turbo he's rocking, but it spools pretty damn quick
