There is a guy in the bargain trader who is selling ford racing 24 # injectors and a MAF sensor calibrated for them. My question is, is it ok to buy fuel injectors used, or is that one of those things you dont do?

Buying used injectors is no big deal. Be sure to ask about the miles on them though. If they have quite a few, consider sending them off to have them professionally cleaned. If you don't have them cleaned, after installing them, run some injector cleaner through the system for the first couple fuelings.

And don't try to clean them yourself. Odds are you'll damage them in the process. They're pretty delicate inside.

now, if i get these injectors, besides upgrading the MAF sensor for 24# injectors, is there anything else I would need to do, or can I just swap them out for the 19#'ers and it work just fine? anything at all??? I really dont want to put them in then realize i need new fuel rails, pressure regulator, and pump. Id like to get all this before I decide on the purchase Thanks!!!!

They'll swap in no problem...direct fit....long as the MAFs cal'd for them, your all set...I'd def throw a Kirban AFPR on the list, your gonna want to have the ability to tune....pumps not a bad idea anyway...gotta have the stuff to support the mods...

am i gonna see any problems with flodding or choking and the sort though, or will the recallibrated MAF sensor tell the computer that its different, also how about differences in gas mileage?

Things should be all set...Tons of guys swap to 24s....pretty much plug and play...It may stumble a time or 2 til the computer catches on and relearns...running 24s on a 19s puter "could cause some issues, but I think overall things are ok...
Some guys run chips, or TwEECer the tweak 24s into the puter...I would get it running and kinda dial things in then head for a dyno tune to nail it down...

Someone who's done the swap should chime in..I opted to stick with 19s versus running 24 with the stock 19s puter....i was leary and didn't want to mess around with possible gremlins, nor did i want to get a chip burned...But as I mentioned, plenty of guys run 24s with the 19 puter....

Call around to your local parts stores. One of them is bound to have a test stand for fuel injectors. It will test and clean all of them before the install. If there happens to be a bad one then you'll need to buy just one instead of a hole set. It's also always a good idea to put new seals on the injectors prior to installation along with just a dab of silicon grease.

Make sure the lower cap is together. Seen way too many sets with missing lower caps due to damage. I hate that.

You're right. The Cobra computer accounts for the 24# injectors even with the same MAF as the GTs use.
