I have a garret t3/t4 .60trim I am looking to put this all together very soon, I am just curious of what size injectors our good for the horsepower range.? I am only boosting 10lbs.

 

I am running rc 550's on my turbo b16 on 9psi on a t3/t4. 550's are good to 300-375whp.

 

just get some 750's or 880's

 

440 or 450cc should be plenty if your trying to stay cheap like sayi get some dsm injectors but id say go ahead and get some larger like 550 cc if your gonna spend the money and get rc or something so when you go bigger (aka boost happy) you'll be ready

 

Precision Turbo 440cc injectors would be ideal for your application.

Put in your horsepower goals, and this should give you the approximate sized injectors.

 

Good link, best answer in this thread.

this should be a sticky (maybe it is in the FI FAQ I cant remember) I have seen so many questions in injector size lately.

(*edit, I just checked in the FAQ and within 30 secs I found this http://www.robietherobot.com/storm/f...ectorguide.htm

 

always go bigger....

 

to an extent you wouldn't run 1600cc's on a 300whp car

 

440 or 550s would be fine.

And I can never get a good answer out of that RC calc. I think I am stupid or something, haha.

 

DSM 450s, got mine for $25

 

good eye!!
nah everyone seems to suggest 450cc-550cc which is fine for 10psi...but
what i meant to say is step up to 750cc or 880cc

i'm running 750cc at 8.5psi if i want to turn up the boost
n dont have to worry about maxing out the injectors..

IMO

 

450cc should be fine.

 

 

ya get me some for $25 lol

 

and make sure that they have been cleaned and tested (add a few bucks). I wouldn't use them however, and 550cc injectors will do more than fine.

Don't be cheap, do it correctly.
