Injectors dont fit.. any ideas?

[Prettyboy]

Alright I ordered Precision Turbo Injectors 550cc from 3sx awhile ago and I am just now getting my motor back together. Well i stumbled onto a problem, the injectors don't fit into my stock fuel rail with the clips that are on the stock rail. So do you guys have any suggestions as to what I can/should do? Are there clips i can buy that you know of? Please let me know ASAP trying to get my car back out on the road!

Are you sure they are seated? The lower plenum insulators get hard and dont let the injector go down and could cause issues.

You talking about the injector retainer clips? if they seat on the lower plenum and fint inside the rail , those clips arent really necessary

In for a update. I have the same exact 550's stored away to be installed when I get bigger turbos.

The stock 360cc clips do not fit on larger injectors. Dont worry about it, once you have everything tightened down properly they wont be moving around.

i remember reading something on pte's that the bottom plastic piece is larger than stock fuel rail holes.. some other company rebranded them and cut that plastic piece down to fit if i remember correctly

If they where sold by 3sx then the they should have the correct upper and lower dimensions.

I have a set of Injectors Dynamics ID725s and Im not sure if the stock lower cushions will work with them. Does anyone have a measurement for the stock injector lower port? Want to buy new seals and cushions but don't want to buy the wrong ones.

I`ve used Evo 450`s, PTE 780`s, PTE 1200`s all without the clips and all without problems, the rail is bolted to the intake manifold, the injectors are going nowhere..

the other guys are right, you dont need those clips.
