1.5mm metal gasket
Intercooler Pipings
255 Walbro
Sard Fuel Regulator
Tial 38mm wastegate
E3 big 16g turbine
510cc injectors
EVO Ecu n Wiring
609 Air Flow
3" full exhaust pipings

Items tht i have but not installed: stainless steel 2.5" diameter banana not flanged

What i have in mind to play with 3k-4k
achieve 1.4bar boost

-Piggyback
-18g turbine upgrade
-20g turbine upgrade
-clevite engine bearings

do i need to pump up to 600cc injectors to accompany the turbine upgrade and is a piggyback enough for the performance.

I reckon with yourset-up and budget you can up the boost but get a standalone... and it will be much safer and better in the long run. : )
