I'm upgrading my stock injectors to something bigger and I was wondering what stock injectors from another car would fit my S4 TII fuel rails with no mods. Also what are the largest injectors I can fit on my stock fuel rails?

 

I don't know what injectors from other cars will fit, but why do that anyway?

Why not buy injectors that are sold for the RX7's?

I believe 1600's will fit in the stock rail.

What are your goals here? Do you have fuel control?

 

Cuz I ran by a crapload of fuel injectors at my friends house that his dad just had laying around. I was just curious... I have a standalone...

 

It's not worth the trouble to use them, especially if they are used.

 

Some are new and some are used.

 

You really dont need a aftermarket fuel rail. Stock one works fine and you cant see it anyways.

 

stock rail have been tested to flow enough for 600 whp. also, i had to get my 1600's machined by bnr.

if your gonna use them, send them out to witch hunter performance, and they will do a top notch job on them.

 

Sweet...
