I Think I will change my fuel system abit, but need some help..

The engine is a rotary 13b P-port with a GT4202R turbo with tial rear housing and tial 60mm wastegate.
I have 6 x 1680cc Bosch/Ford injectors.
There are 3 Fuelrails with two injector on each with AN8 fittings on the ends.
Autronic SM4 and CDI 500R with Crane Cams 92PS coils..
Rice Racing WI system pre turbo.
I`m looking to run about 30psi/2bars of boost and looking for about 800hp.


The setup I was going to run where 3 A1000 pumps from surgetank and a A2000 to feed the Surgetank..

But I was hoping to get a simpler fuelsetup..

Anyone that can help me about this?

seems like you got it all figured out. but i would run 8x1680'c instead of 6. what Throttle body and manifold are you running?

Why 8 injectors?


Well if I will run the 4 fuel pumps I will need 2 altenators, as they will pull 120amps..

So I think the mechanical pump are the way to go, just need some more info on it befor I can make up my mind..

6x1600 for secondaries(+ lets say 600-700cc primaries) you will be way more than fine to cover 800 hp. make sure you put (at the very least) 2x 10mm feed lines from the fuel pumps to the rails.

Out of interest, what would be the purpose of this car? Not a daily drive i suppose

as for the fuel pumps. i m not a big fan of the aeromotive pumps as I have heard stories of them going bad. i use 2 bosch 044 (in tank). a very tight fit !! but capable for high numbers

Well I really don`t think I will need more injector..

But it`s the fuel pumps..

The lines I can use AN 12 if that is the case, I have alot of teflon hoses laying around..

well i doubt you can use the 1680s as primary injectors. to be honest i think with 2 850s and 4 1680s you ll have more than enough fuel to reach your goal (and even higher numbers)

1680 on primary is no problem..


But this is not what what I was asking about really.

But what should I do about the fuel pumps?

there is an old IMSA gto 4 rotor FC floating around. they run 4 (maybe its 3?) bosch 044's. one feeds the other 3 (or two?), to a small rail to the motor. HP is about 650ish, so that should give you some idea...
