Injector choices

[s13dan]

I dunno rather to go 550 or 660cc for my setup. Gt28rs,Z32maf, head back exhaust ,fmic. and a simple ass SAFC from 1918... Will be uppgraded soon with ECU tune. 10psi everyday prolly 18 Hi boost. I dont want to stress the 550's but is 660 ganna hurt anything?Drivability? thanx

As long as your car is tuned, larger injectors aren't going to hurt anything. You may as well even go with 740s if they're close to the same price, just for the extra overhead.

Youp

Better to have more fuel than not enough

yeah i want to go 740s when i get my turbo upgrade

def go with the 740's just to be safe. I have a lil more on my setup and i got the 550 from another project that I was doing and if I had to buy them I would have gone with the 740's. IMO

u better make sure your engine can hold that power. larger injectors = more boost.. hope you got a good head gasket in their

wow as big as 740? i know about duty cycles so i suppose with an enthalpy tune and dyno tune and a managment system all will be good?What happens if i dont retune my ECU can i still achieve a proper AFR with just an AFC and wideband? its just that i see 450+hp 240s with 740 and 800cc injectors.

As long as your cars tunned for the bigger injectors it's not going to hurt anything.

It wont effect driveablity

Bigger injectors DONT mean you need to run more boost

You can't run 740's with just a SAFC and a wideband.
