ok i searched
but i cant seem to find a how to and a why to do this mod.
i have see pics of tii lim with 2 extra injector bosses installed but i dont kno
why they do this and HOW to do this.

honestly im more interested in tig welding some holders for water alchy injectors.

but want to get more knowledge

 

I'm not sure how to interpret your question....

As for the "why": To allow more injectors, which increases the amount of fuel available to run more boost, upgraded turbochargers, E85, etc.

The how: Buy some injector bungs from a place like ATP Turbo. Drill a hole in the intake runner. Insert bung. Weld in place. Plumb the fuel rail. Program EMS for the additional injectors.

 

ADI injectors are different than fuel injectors. Just go to the website of your favorite ADI injection kit and see the installation directions.

There is also an "Auxiliary Injection" subforum on this website:

i know waht hes talking about... where the secondary injectors are, another set of injectors are placed in the other two runners( where the zero start crap is usually at) where the injectors are non-existent.. ive seen them craiglist a number of times

 

Hes refering to not understanding what exactly the question is. Better know how to tig and have a good standalone to control them.

looks like this.. is there a specific how to.. better yet whats the name of the mod so i can read up on it .

 

i didnt think the stock fuel rail would flow enough for 4 injectors...
