Plugging primary injector holes when converting from EFI
 

Hey guys, the center iron on my 1994 13B-REW motor has two holes for primary injectors. I'd like to plug these shut, and from what I've gathered there are a few ways to do this:

1. Leave OEM primary injectors there and hope they don't create a vacuum leak.

2. Racing Beat injector plugs

3. Mazda Racing injector plugs

4. I've heard that other setups might exist also, but haven't spent too much time looking yet.


I'm hoping to get opinions, suggestions, and/or reviews from people who have used any of these methods. I'd like to do something that is easily removable for now, in case I might want to convert back to stock.

Thanks,
Scott

Rogue Wulff has a nice looking injector blockoff kit. He's on this forum.

I wish I could say I made mine. Cause I could prolly sell a few of them, with the "NO PISTON" logo engraved into it.
Aside from being black in color, and a little thicker at the top (along with the custom engraving), it looks quite similar to the RB injector blockoff. I can't remember 100% for sure, but I believe it has the letters "M R" beside the no piston logo. Mazda Racing perhaps?

Thanks, guys.

Rogue_Wulff, got any photos?

Sorry, no pics. Camera broke, and I'm too cheap to buy another right now......

I made some many years ago ,the test manifold with a carb is in storage .It was used to start EFI motors on the test stand .

put the "dead" (no connection) injectors in and plug the rail with easy to find threaded plugs.

Thanks for all the advice guys, I'll probably start with the method suggested by KGParts unless I stumble across a very cheap set of RB or Mazda Racing plugs.

i should still have a set that im not using, shot me a pm

Freeze plugs work great and are cheap as well as removable.
