30# Injectors to Large, Right?

[Hickfied]

I am hopefully buying a 90lx 5.0 5spd this week. I have not test drove the car yet, but I think that it will run rich with the 30#er's on it. The mod list is as follows:

khumo tires (all weather) 265 40 17 front 285 40 17 rear less than 7000 miles on the

e cam w matched valvetrain (ford motorsports) springs, lifters, pushrods
1.7 roller rocker ( crane energizer)
30lb injectors (ford motorsport)
cobra upper intake
gt40 lower intake
cold air intake
superchips performance module( not installed)
77 mm pro m mass air
edlebrock 70 mm throttle body
new bosch platinum plugs
new 8.5 mm racing wires
new msd blaster coil
new msd 6al ignition box w adjustable rev limiter
new cap and rotor

If I purchase this, it will only be a DD, nothing more. I have my "drag car". I was thinking about swaping out the MAF and injectors for a stock set I have laying around. Maybe try to make some money off of it. I don't think the 19's will be to small... But what do y'all think?

19's should work fine.

 

[Sicarius428]

19s will work just fine for your setup. You don't need 24's till you get to about the 320 rwhp area so ya, 30s are gonna be a bit much.

Definitely sell the 30's and make some money to buy a good MAF to go with your 19's.

I had a '94 cobra motor with E303 cam and 1.7RR's. Headers, exhaust, throttle body, MAF, etc... I still had 19lb injectors and they worked great. I sold the car to a buddy, and he put 24's in it, and said there was no power improvement at all.

I would recommend not installing the superchip. I've never had one personally, but I've heard they kill gas mileage and don't offer any improvement. Just bump your timing to 14* and you'll get the same effect.

Yea, I asked the guy and he saud he already took it out along time ago. I figure I can also sell it to some riced up domestic

 

[Grn92LX]

30's will be fine.

 

[gcwh02]

you can go 19 or 24 but ill say 19 since its your DD

 

[5spd GT]

It will run with 30's.

Is 30's ideal? Not even close!

Go 24's at the max, good luck with it!

 

[stangjunkie]

ditch the bosch platinums and go for some autolites

bosch=

30s might be fine with the aluminum shift knob and kumo tires....

umm don't go back to the stock mass air thou it will choke the hell outta those heads, but i think 19's will work great, i called trick flow becuase i was gonna get one of their kits and they said with h/c/i, 24 were a must, so i bought some, and now with my setup the 24 makes it rich, imagine that, idiots

idiots? they prolly make that say a "must" becasue if you under inject it, you will blow it up. they obviously have a reason for saying 24s becasue it makes premium HP.

how do you know your car is running rich? what wideband do you have? my car smells rich, but its not!
