True...



Now, where do I go about getting the rails and proper injectors?

Gotta be careful with the 850cc primary's. If you modify the stock fuel rail to fit the stock secondary's in the primary rail, the fuel pattern will be off...it'll spray on the sides of the bung vs. into the engine first. You should be plenty happy with 550 primary and 1680cc or if you've got the cash, 1300cc secondary's which is considerably cheaper in the long run since you won't have to do all a/n fittings.



On a side note, my fuel system(550 primary, 1680cc secondary, aeromotive fpr, a/n fittings, dual FD pumps) cost me almost $800~ so you gotta pay to play. They sell an adapter in Japan that allows you to fit the 850 secondary's into the 550 primary slot(let's the 850's sit lower in the injector seat). I'll be buying this since I want to see how much power/boost I can get out of my turbo with 85% injector duty.

What would a set of 1300cc secondarys run me? I'd need a rail too right?

walbro 255 pump and 550/1680's

yes if you keep your foot out of it, you should be fine

I'd say **** the supra pump, the walbro pushes 255lph compared to the TT Supra's 196 (I think).

Aeromotive A1000 with 750/1680 injectors, custom rails, -10 feed, -8 return, SX FPR, twin Aeromotive filters, and a distibution block to run both the rails in series instead of in parallel.



That is my setup at least.

Try 290!

i still think the walbro pushes more fuel.. i think they did a comparison on it... anyways... i've never seen anyone use 1680cc inj... need a rail for that and stuff.. i assume lol

Supposedly the Walbro can keep the flow going to higher pressure than the Supra pump, therefore advantage to Walbro when the boost is high.
