Are svo injectors plug and play on lt1 cars or do i have to modify any thing? also these will be going into a 94 ybody. thanks Daniel

 

They will "fit" and the harness connector will plug right in. Where you will have a problem is the retainer clips usually will not fit. Most people just leave the clips off.

 

they will not leak with out the clips? or is it that the fuel rail is bolted down so this keeps them tight

 

no they should not, mine dont and i left the clips off

 

They get sandwiched between the rail and the intake and will not fall out. On one set, I was able to get the clip in the grove by sliding the injector out of the rail slightly.

Currently running some Bosch injectors at 58psi and there are no clips, and no problems.

 

The fuel rail will hold them in, but I got the clips to work with my 30# SVOs anyway - you just have to be careful which groove you try to use - if I remember correctly, some of the grooves were too big in diameter but one of them fit. If you get them clipped in and they are positioned right when you bolt down the fuel rail with both o-rings covered, then you are good to go. Don't forget to reprogram your PCM for the larger injectors if at all possible.

 

i was going to add that because i figured out at the end with a little force i could get mine to clip in with the injector slid out a bit. but i figured with it being sandwiched in like that i did not really need them anyway

 

Also place a thin film of motor oil on the new o-rings for easier installation and blow off the intake manifold around the injector area so as not to knock dirt in the holes.
