Hey my dad needs new injectors for the 90 Formula. The specs are

ZZ4 Crate
1 5/8 inch Edelbrock headers+y-pipe
3 inch American Thunder Catback
SLP Runners
Lingenfelter intake

B&M Flexplate
Stock 700R4
2.73 Rear

He just got a set of Venom injectors in the mail, but the injectors were tossed in a box and shipped. He's going to send them back to Summit.

 

24 #/hr. That's what I'm running with my setup. They'll support up to about 400 hp.

 

400 hp easily.
You should have no probs with a 24lb/hr injector.

 

That's what I am using! Ford SVO 24lb'ers.

 

What type of brand do you guys suggest? My dad wants 30 lbs injectors because that is what Summit suggested.

 

I am using the SVO Ford Motorsport blue 24lbers. You can get a set rather cheap-- new. Or you can usually find some for sell for around 100 bucks or less -- on the classified boars.

 

I'm also running the SVO injectors. Got them from Summit.

 

If you are running a ZZ4 cam with no head work and just the mods you listed, 24's are more than adequate, plus an AFPR. 30's would be a bit too much. Summit must have a sale or trying to push old stock. You are running a combo pretty close to what I was. From experience you need a set of gears, torque convertor, tranny cooler, and at least a shift kit. 3.73's or 3.42's would wake it up! You would swear it was a different car, trust me, been there.

 

The car is my moms daily driver.

My dad still wants 30 lbs, one reason is the GN came stock with 30 lbs injectors.

 

The GN was also turbocharged..
