I am planning a new fuel setup for the FD, i converted the turbos to non-seq, i have a downpipe, midpipe and RB cat back. I also have a power fc and am planning on running about 15 psi. my question is, what injector sertup is best and safest?

 

I would say 1300cc secondaries and a walbro fp would be more than enough. Make sure you get a good map/tuned though. Def. help if you have o have access to a datalogit.

 

^ yea dat sounds good.

 

1300 or 1600 would do. I would use the 1600 to keep the cycle duty down. If I recalled correctly the 1300 have the tendecy to stick. I don't know now since I have been out of FD's for a while.

 

i was originally thinking 1300's but i also have heard about them sticking and burning up. i had thoughts of 850 primaries and 1000 secondaries. any thoughts on that setup?

 

i had 4- 850's in and it was perfect and cheap. ran 15psi high and 10 low. never say above 70% injector duty

 

what were your afr's in the upper rpm range?

 

i was staying at 11's the whole way thro. me and a 2 other buddies all ran the same setup with the same map and it worked great for all of us.

 

yeah I forgot about using 850 as primaries.

 

What's the point of upgrading injectors if you're just running stock twins?

I've run @ 15psi with just a Supra pump & PFC tuned for 11.8 on the button for years and my duty cycle is just fine
