Any workshop have good review of bolt on turbo?

Planning to bolt on turbo my manual Preve, looking for workshop around Petaling Jaya, Subang, Shah Alam, Puchong, Putrajaya is recommended, by as long as within Klang Valley also can la.

well i personally compare directly cfe and iafm+ crankshaft is the same, thus in order to make the iafm+ engine able to handle high boost above 0.9 bar u can just upgrade it with cfe conrod and piston, throw in a racing oil pump and it will handle the boost reliably.
