i want 1600cc injectors, but i want them to fit in stock rail, and i dont want to mod the injectors







so give me an answer

use the flux capacitor.

or dont post 15 year old stupid bullshit in my post?



please let the car drivers post real answers

i know you dont want to, but did you see the website that shows you how to modify them? All youre really doing is putting new o rings on. Other than that, i dont know any place that sells 1600cc's that are drop ins.



But for the price (i can get them 60 bucks per injector) it doesnt seem to bad to modify them, or get one of the nice looking new fuel rails. https://www.nopistons.com/forums/pub...IR#>/smile.png They are pretty ... and expensive :(

yeah i was gonna do the mod....but i dunno...i wanna be able to reuse them if i get something different



and im not ready to splurge 500 on a fuel system right now

i know where you can get a secondary fuel rail for dirt cheap. PM me if you are interested.

I toyed around w/ going from 1300's to 1600's and asked Cameron at Pettits. He looked at me and asked if I was planning on making over 500RWHP. I said no. He said then dont waste your money.



So I ask you, What kind of HP are you shooting for.



Have you ever seen this fuel calculator?? Its handy.

yo i have 18800 hp



jims go online you tit

i'm not sure if he's here but carx7 on the other forums modified his stock rail, not the injectors.

yea i do too...but changing the secondary rail = no more FPR = need new FPR = need new lines = need new primary rail = need whole new fuel system

My suggestion.......Forget 1600cc injectors. You don't want to do or pay what is required for 1600's soooooooooooo.........leave it alone https://www.nopistons.com/forums/pub...1047683561.gif .

because i can use 1600cc injectors WITHOUT doing all that....what arent you understanding



ive seen you post like 5 times and they were all already stated, or just not relevant to the thread

Never go cheap on a fuel system!

yeah but if it works .... :/

"So youre so smart...eh". Its people like you we associate with sorry fire stories. "So youre so smart.....WOW". At least you read my posts......intresting were'nt they.

Have you recently checked and seen how many posts you have on this forum https://www.nopistons.com/forums/pub...IR#>/wacko.png . If you have that many posts and are considering silly S*** https://www.nopistons.com/forums/pub...IR#>/blink.png like you are now I would not take the time to check all the crappy stuff you may have asked and posted in the past https://www.nopistons.com/forums/pub...1047683358.gif .

You having a brain FART stupid https://www.nopistons.com/forums/pub...IR#>/wacko.png ? Continue pretending you dont understand anything. Thats why you know nothing!!!!!!!!! https://www.nopistons.com/forums/pub...iss-monkey.gif

Damn everyone chill out. This isn't even GenD. This is nopistons, save the drama for the evil forum.

Now children, don't make me lock the thread!



I'd just buy an aftermarket FPR, and modify your secondary rail. Like Turborotor said, don't go cheap on the fuel system. Are you still running the stock injectors? EMS? Turbo?

stock turbo...haltech e6k...walbro pump, otherwise stock fuel

hmm funny i have 1600 secondarys and i dont have 500hp https://www.nopistons.com/forums/pub...>/rolleyes.gif then again they're prolly running at like half duty cycle, maybe when my cars running agian and i get a new turbo i will have 500hp...HMMMM.

think of it like this. Buy 2 1600's .. 70 bucks a pop. modify them. THEN, when you decide to spring for a more complete fuel system, buy 2 more if you cant use the modifed ones. 140 bucks, no biggie. It doesnt look like theres anyway around it :(

Marren makes drop in 1600 injectors. They are offered through their pro-import series injectors. They run for 115 a piece. I don't think they are listed on the website so you will have to call them.

you dont need 1600s, the stock turbo will see to that. if you tune it right you can run like 13-14psi on your setup with the fuel you've got, until the turbo is quits

Just modify the stock rail. If you **** it up, you can find another one for

$15-20.

Ditto, stocker runs out of steam at upper rpms.

hey... that caculator is fun i just found out that i need 9999999999cc primary and 9999999999cc secondary injectors with my ecu running at an 80% duty cycle to be able to maintain 4610996363.2 hp at the flywheel.



the thingy is warning me to change my stock fuel pump, but i think in can manage with keeping it.

Not safe on the stock 89-91 rails. The surrounding bung is too thin and can crack when you bore it out.



Seriously, folks, there's an easy solution to this.



Find a stock secondary fuel rail from a 1987-1988 TII. This will use banjo bolts instead of welded ends, and the fuel pressure regulator bolts on and off as well. Use this rail with the stock FPR and you will be fine.



Next, take your S4 fuel rail and bore out the holes to 35/64ths (0.547"). If you look hard, you can find a drill bit for this (http://www.arizonatools.com/catalog/...4/detail/1355/). make sure to set your depth lock on your drill press. Then, chamfer the ends so you don't destroy the o-ring when installing them.



Now you have a rail that bolts on in the stock position, will fit the stock fuel lines, and costs a total of $20 if you source one used, with a stock FPR.



If you are uncomfortable properly drillign this, just take the rail to your machine shop.





Your other options include: having a custom fuel rail built, which is more costly than you want, or using a stock o-ring and trimming the injector, which you also don't want.



Hope this helps.
