"Best way to tell is post as much about your mod list as you can. We can probably give you a general idea if it will work or not (or there are multiple websites out there that can calculate from HP and engine variables to what size injector you need)."


where might we find one of these websites bumpin?

 

not positive on a turbo build, but i would imagine that it cant be too much different than a blower build...you will run out of injector at around 300 WHP maybe a touch under with a blower car.....

 

Skip the L67 injectors- I ran them for awhile and max'd them up and recently upgraded to Lightning 42.5s I got for cheap. If your going turbo, those L67 injectors won't last you long, and you'll be wishing you'd have gone bigger in no time at all.

 

Found them in the past on a google search- if you can't find them, I will look for them.

Really? I would think L67 injectors would be fine for any moderate 3400 turbo build- but I guess it depends on the rest of the setup- I just know some L67 injectors go on clubgp for very little money.

 

Hmmmm reading > me, I missed the part about it being a 3400. Still, #33s are pretty small for turbo stuff. Even really mild L36/turbo builds usually need #42.5s. I guess if you got them for cheap enough, why not. That said, if you search Ford forums you can get Lightning injectors for just a tiny bit more, and they'll give you alot more room for growth. There is always going to be a "more boost" temptation.
