TL_V70 And NO MBC don't do it thats where people come unstuck. Pistons and rods are not super necessary it depends how you drive and how its tuned and how much boost.
Coil not needed fuel pump is if running bigger boost or to replace old tired unit and bigger intercooler is recommended ebay do $250 dollar units . Deautschworks DW200 is fine and not to expensive or hard to fit for a fuel pump upgrade.
To modify an 4.4 ecu to tune with is a not to hard either there are cheap ECU's out there and if your confident the can be DIY Moded

MBCs have been used to great effect for ages, I gave mine extra turns every so often, didn't have a AFR meter, it was great fun and epic boost, perfect with auto box , in comparison, a V70T5 with no MBC crapped it's auto on me.
The rods are fine, it's an urban myth they bend, you only hear about the ones that bend and you don't know how stupid the owner was in doing so of course. You don't hear about all the successes.....
