im thinking of doing a t2 swap on my 86 fc (base model). my question is if i get bigger injectors on my n/a can i transfer them to the t2 motor. also how big can i go with the injectors in my n/a before i have to change something else.

 

You can go bigger injectors but im not sure why you would want to. I believe you can put in 550s from the TII but why you need them with the NA is a much better question. If you need more fuel make sure you have done the fuel pump rewire. then when you get a TII youll most likely get the injectors

 

I can tell you that if you get larger injectors for your N/A, it will run like ***, unless you have some method to control the injectors. Rotaries run rich already, and the NAs are running Pig Rich from the factory. BigDongsr94 is right, you'll likely have the injectors for when you go to T2 anyway, so why worry about it now?

 

On the topic of fuel and na's, how much hp can the na fuel pump for a s4 support? Thanks

There is no valid reson to change the NA injectors unless you have somthing along the lines of a large P port, N2O, Big turbo. Doing so will result in nothing but pore runing conditions.

There is allso no fuel pump relay to rewire in a NA. So dunno what you are refering to here. :-/ The whol rewire deal is for TIIs that have a fuel pump resistance relay that drops the voltage under low RPM range to prevent flooding or pig rich conditions from low load and to high of fuel pressure.

You can fit 1000cc injectors if you want and get them for a FC the size dosent realy mean much. 550s 650s 920s they all fit.

If you swap a TII engin it will have injectors why do you want to buy more and put them into your NA? Sounds like extra work with no benafits to me.

 

If you run the numbers, it's about 200hp at the wheels on a DynoJet.
