Injector selection questions .....

[nightspeed87]

Well I have a 6bolt 2.0 going in with 2g pistons and etc,
I currently have a walbro 190lph on stock injectors and porte 14b,
but my future goals are appox, 300- 350 whp on possibly a super 16g
with a supra 260lph fuel pump, logger, full 3in exhaust, afpr, fmic, and a safc2m and maybe camshafts...
What size injectors would one evaluate for me to run ( the biggest possible with that set up) Because I need to clear up some speculation that Ive heard about with
a safc you cant properly run injectors bigger than 620cc...Is this true?
I dont have a eprom ecu, and I most likely wont have the money to get dsmlink
at least not anytime soon, so i need to know what I need with the set up I listed above
to reach my hp goals. I dont know how much boost it takes to get up there but I hope it wont take
over 20lbs to reach that goal, plus im going to be on 93 pump gas.. ( Like I said im going for at least 300whp and no more than 350 so in that range, and I know its somewhat hard to tell this because of other variables but Im sure you guys have an idea... ) Thanks...

It s either 550. or 660s
You should be alright with 550s, even though u might want more power, or whatever i d go with 660s just to be safe
You will be able to tune them with the safc
You also might wanna get a Maf from a 2g
You could also always go with a chip which should make your car easier to tune, and give you cool options.
Get a datalogger, an an EGT
That should be very good to start with
hope that helps

yea its givin me an idea... See ive never been in the market for bigger injectors
so thats why I was asking these questions.
Id probably want to go with 660s and just gone and get as big as I can safe run properly incase my upgrade demands ever rise in the future... So the safc2 can properly
tune the 660s and have it run like the 450s in normal driving situations?
Because I know once you go so big with injectors size you'd want to get dsmlink to properly tune... I know id probably need a wideband 02 with that safc2 correct?
And what chip are you referring to? Also, I was going to do the 2g mass in the near future, but doesnt the 2g mass make it harder to tune with because you also need more fuel just to compensate with the added air the 2g mass is running? Will I still be able to run about 20lbs of boost with that mass on those 660s>?

well the old safc with 5 knobs will maybe a lil less street friendly but yea the other ones, properly tuned it will be like drivin the 450, exept more fun
Those chips, such as www.tmo.com altough it looks like they dont sell them anymore...
or http://www.dsmchips.com/, will make it even more easier to tune with (check the 3rd stage)
I m sure you ll have fun lookin at those options
You will obviously be able to tune it better with a wideband, and I will obvously will advice you a dsmlink instead of a safc but it s not everybody that could go that route.
You will be able to boost more than 20 psi, I dont know what turbo you will get but considering your need, you re probably end up with a evo316g,safc and a 2gmaf, lot of people went that way, (and me 2 so i went thru all of this)and some with good tuning went 11 with that set up and the supporting mods youre planning to have
