what injectors for my build??

[bobpogoman]

ok i got a well-built 7mgte, topline pistons//rings, wiseco cometic hg,nippon racing valves, engine got about 15 000 kmd on it.

i got a walbro 255 lph pump, aeromotive fpr,3inch straight exhaust,crazy sounding unknown Bov,brand new oil pump oem,fluydine rad with flex-a-lite electric fan, and some things i forgot.
Apexi Safc-1 (old one not electronic) i will buy safc-2 later

upgraded ct-26 to 60-1 trim.

im willing to do 19-20 psi, only thing left to buy are:
from suprasport

Spearco replica fmic,
Lipp ic piping,
wideband o2 sensor/cable/gauge (Innovate MotorSports DB-Blue Gauge / LC-1 Kit),
Dual Stage Boost Controller with electronic switch for low//high boost
Injectors with clips.

here are my questions:

for the intercooler, the spearco kit to fit stock piping will fit with 2.5inches lipp ic piping? and is it good for 20 psi?

for the injectors, what size? 550?650?750? i would say 650 but not sure.

for your mods listed there go with the 550's you wont overrun them. people tend to make over 500 hp on a walbro and 550cc injector so you should be good.

yeah, 550's I have a ton of fuel left and I'm making about 375rwhp on a 57trim CT.

but, for a couple bucks if im getting 650 s it wont hurt? ill just lower my fuel psi. i mean if i wanna upgrade more later... i can get 650 and it will work for now ?

and for the ic?

stick with the 550 or the car will run too rich off boost also it will make you run toooo much timing unless you go standalone

 

[bobpogoman]

kk ima go with 550 s but for the intercooler?

 

[Jimmysmk3]

the intercooler should be fine might just need to make some minor modifications.
