I've read a bit about injectors and i know i want to go with 720 secondaries for right now untill i'm ready to go bigger and get more power, will these denso's work for my setup?

Currently running stock TII swapped into N/A with full 3" Apex exhaust, intake, FCD, and soon to add FD Fuel pump.

Assuming this is an S5 engine, you will need high impedence injectors. As stated in the listing, those are low impedence. Also, with 720cc injectors, you will need some sort of tuning device to adjust the air-fuel ratio.

 

I have those exact injectors in the primary position on my car. If you have an 86-87 1/2 they drop right in with zero modification at all. If you have an 87 1/2 - 88, you will need to file the tab off the injector side to use the factory connectors. You will also have to wire in resistors... I prefer 6 ohm 10 watt because that is similar to the stock resistors.

If you have an 89+ you will have to solder in new injector connectors (Bosch EV1) and wire up resistors.
