Yea I get that. But the turbo is a luxury, not necessity.
And not to smash windows here ba's good luck angel must be farking the devil atm.
I'd hate to see all this work again go into the motor then have the cheap turbo do an impeller an fark the internals.
Just smash some 3" mufflers in the system and sell the rest.
Either way it's ba's decision but if it were me I'd take the time, and rebuild an NA motor and have reliable motoring for the next million kilometres.
