Fuel injector options

Michael DeLoach · Nov 27th, 2002, 12:18 PM

If I turbo my GA16DE do I need 370cc injectors or will the 259cc injectors from the SR20DE be good enough. The reason I ask is that I have a set of perfectly good 259cc injectors just laying here in a box. Your input is greatly appreciated.

Thanks.

depends on how much boost you're going to run

I will most likely be running somewhere between 7-10 lbs of boost. I don't know how much more than that a GA16DE can handle.

The stock SR injectors will barely handle about 7-8 lbs.

Get an Apexi S-AFC either way.

Well I was able to get some 370cc injectors for $125.00. What exactly does the Apexi S-AFC do? Thanks

if u dont know how to use an AFC (piggy back fuel comp)....stick with a JWT ecu, ur car will last longer.

I do plan on using the JWT ECU. I was just trying to get info about the AFC since someone else brought it up!

The AFC allows you to add/subract fuel where it's needed. It's an excellent tuning tool but like mentioned above the JWT is safer unless you really know what your doing. I plan to use teh AFC along with the JWT ECU and a Wideband o2 so I know exactly where fuel needs to be changed. The Greddy Emanage is another piggyback that is actually better than the AFC since you can adjust timing curves as well as fuel.

SE-RtinMI, Thanks for the info......

Assuming you are going to be running 5-7PSI of boost on the street and maybe at most 10 PSI at the track. Will using 370CC injectors affect your car economically while using less boost on the street??
