i just got an edelbrock turbo kit and i've been told that i should upgrade to 450cc injectors. the kit come with another set and also runs with the stock set. how would i plug one set so that i could just run one set of 450cc injectors?

 

if you want to block the extra injectors holes in the manifold simply use frost plug
install them with some red loctite

 

how do you frost plug them?

 

I had the same problem, glued plugs.. .well one plug got blown off and rest 3 were loose... What I did then was to thread it and put threaded plugs in the holes with threadlocker, works fine and they wont fly off on boost.

good to know. where did you get the threaded plugs from? And would it be fine if i just upgraded one set of injectors so that together they equal what i want?

 

If your ecu supports dual injection, sure I guess.
I got the plugs from a local bolt store.

 

do you know if thats something that could be set when it is tuned?

 

if your ecu supports dual injectors I would assume yes, however I wouldnt know about a particular ecu.

 

hmm. alright i guess i could call up a tune shop to find out. thanks for the info on this. if anybody else has any other good ways to plug them let me know.

 

You could tap it like the other guy said and use a plug to do it. Here's an idea...http://www.niagaraplastics.com/threaded_plugs.htm

 

Thats basically how I did mine. except my plugs are metal.

did you just get yours from a hardware store? so i just need to screw it in with some locktight and i'm good. how did you get the treads to match up with out having anything to compare it to?

 

I measured the hole, bought a tap and tapped the injector ports to match the plugs I bought. I bought them from a bolt store, but keep in mind this is europe, so things are bit different.

ok that helps. what things are different in europe?

 

we use metrics and we have bolt stores that just sell bolts and plugs But I dunno if home depot would have them and depending on the size a 1/4 NPT tap and plug might suit you well.
The plugs I used were M12x1.5 thread...

did you have an edelbrock intake manifold?

 

Measure the hole size, research what drill size is needed for 3/8" and 1/2" NPT threaded holes, then get a plumber or machine shop to tap & plug them with ordinary brass NPT plugs. They hold far more than the 60psi a water system sees, so they will work fine for 10-20psi on your turbo kit.

nope, stock toyota, but I plugged the injector holes on the head, not the manifold.

I'll look into that.

i would rather be able to use the injector holes in the future if needed but if i don't could i just weld the holes closed?

 

well i haven't recieved the manifold yet, its still being shipped but i just called edlbrock and found out it comes with plug so that you can just run one set. thanks for all the information though.
