Hey,

I had a question about upgrading my fuel injectors on my S5 TII. Rotary Ressurection says the S5 13BT uses High Impedence injectors.

Im having a very hard time finding high impedence injectors past 550cc from any company.

Kevin says that:

Does everyone who upgrades injectors on S5 TII's have to do this? Or am I just totally missing something and not looking in the right places for injectors?

Thanks.

P.S.: Im looking at buying 4x 720cc Injectors

 

That's because they are very rare.

Pretty much, yep. This applies to all post-87.5 FC's. The resistors are cheap and easy to install.

 

I thought fc's had low impedance injectors? I got greddy 720's and didnt have to do a thing. I didnt know there was a difference on s5's.

 

S4s had low impedance up to 87.5, then they transitioned to high impedance.

 

I have RC Engineering 750cc secondaries on mine, and I have no complaints.
About $98 bucks a pop IIRC.

 

You should easily find the which resistor you need by searching...I looked into this a while back.

 

Okay, you guys answered my question.

Thanks
