I am currently having my car built but I have a few questions for you guys with big builds already because I feel like I may have over looked some stuff but maybe not? HELP lol

the brief set up...(major things at least)

ETS T4 turbo kit with a twin scroll ball bearing Precision 6266 turbo
ported built head
kelford stage 2 cams
ERL sleeved block
CP 87mm pistons
manley turbo tough rods
buschur double pumper
FIC 2150 injectors
jacks transmission
jacks upgraded pins in the Tcase

my main question's are this...do I need the following thing to reach my wanted goal of 700 maybe a bit more lol

FUELING..... do I need to do bigger then stock lines? and do I need a upgraded fuel rail? my friend has a 615 awhp evoX still on the stock fuel rail and fuel lines, so do I need to upgrade? I plan on e85, maybe E98 or c16 for when we wanna turn it up for race nights (I have the buschur double pumper already)

AIR FLOW.... Do I need to buy a new intake manifold, port the stock one with buschur, or just leave it? and also if I do need either of these should I need a throttle body as well?

TUNING....
I plan to have buschur tune the car unless you guys know of someone else I should take it to?... buschur is only a few hours from where I live and of course I hear great things about them,but I am willing to travel if needed... the tune is very important to me and the car obviously, Im new to the evo world! porsche guy over here! haha the evo was supposed to be a daily until I fell in love with it!

THANKS SO MUCH GUYS! the forum has been great so far!!
