o.k i just need alittle help with this, i just remove my injectors my friend got them tested for my and says that six injectors had 16.somenthing OHMS and two had 7.5 so i have to replace those two, he just gave me 4 injectors from his 93 thunderbird 5.0 H.O i just want to know if its o.k to mix 4 of my original injectors from my 5.0 tpi n my iroc and the other 4 from the thunderbird .any help will be apreciated

 

No, you can't really mix them.

But you can buy sets of 8 on eBay and elsewhere all day long, for about $40. This is the style to get. When they're that cheeep, "free" things that you can't use become much less significant.

 

thank you so much for your help , hey so i cant mix them but if get another 4 injectors just like my friend gave me that can work???

 

Sure, if you can find 4 that have the same part #....

OTOH, I think you'll find that you can buy 8 used injectors for the same price as 4, and enjoy a whole lot less trouble. Remember, used injectors mostly come from junkyards. One car = one car, to a junkyard; meaning, a set of 8 injectors from one car = a set of 4 injectors from one car (one car's worth of injectors, in either case); meaning, the price will pretty much be the same.

Forget your friend's. They gain you NOTHING. Buy 8 injectors that all came from the same place and that are all the same part # and move on.

 

hey man thank you again, hey my friend says that if those 4 didnt help me he has a brand new new set of 8 injectors but those are for a newer mustang engine i think its a 4.6, those are not for free haha but he can give me a good price i know that for sure, and sorry for all those questions

 

does anyone know if those 4.6 fuel injectors will fit a 5.0 tpi?????

 

Yes people know that.

Yes they do.

Injectors are, for the most part, HIGHLY generic.

I have sets of Frod/Bosch 19#ers myself in a Cadillac 4.x motor, a Northstar (4.6L or some such), a Jeep 4.0L 6-cyl, and a Chrysler 318.

Note that the person selling those injectors on eBay lists TPI 305s in his list.

The only thing you'll need is a set of new O-rings.... which you'd need no matter what injectors you use.

Some silicone dielectric grease, if you have a packet of that, or some spray silicone lube, makes them all go together much easier.

The 4.6 Mustang injectors are identical, same part #, to those ones I pointed out on eBay from the same motor with some different sheet metal wrapped around it.... so a "good price" would be, about $40-45, plus some reasonable allowance for shipping; maybe $50ish total.
