Car: 93FD

Engine: 13b-REW/2mm large streetport

Turbos: B&R III equivalent (custom job... I'm a test bunny for Bi-State) FULL Non-Seq

Manegement: PMS Purple Box (Yes, hoping to upgrade unless proper tuning can be acheived)

Cooling: Petit Cool charge II SMIC

Exhaust: Full 3" to HKS Hyper

Extras: Efini Y-pipe, M2 Aluminum intake w/hardpipes, Greddy elbow....blah blah blah....



This SHOULD be quite a badass street setup. Hoping to throw up some nice numbers with a good tune. Not getting TOO wild, cause I don't know much about this ECU on upgraded twins.



QUESTIONS: What setup should I run for fuel? What size injectors? Fuel pump and FPR? I will daily drive on 10-12 psi and race on 16-18.



As always, thanks!



Oh, pics to come VERY SOON

Nice, I would think that you are definitely going to need an ecu upgrade if your getting better turbos.

I know a guy who tried running a purple box on a to4s and blew his engine.

550 primaries and 1600 secondaries with a PFC should do the trick.



Did they give you the turbos?

O yeah...just run a supra pump its way cheaper and it goes right in.

No, I'm paying for the turbos! Just got a little help... https://www.nopistons.com/forums/pub...IR#>/smile.png



Roger that on the injectors and ECU. Oh, and the pump.



You think I'll be safe to break in the Motor with everything BUT the PFC? If I keep a conservative map and low boost? Just till I have the $$ for the PFC?

supra pump is bigger also https://www.nopistons.com/forums/pub...IR#>/smile.png Aermotive fpr are commonly used. I don't see why you couldn't keep the boost low as you break in the motor and wait for the pfc. Make sure you get the commander w/ the pfc.

Cool. That's what I'm planning on doing.





Hmm... Ok, so NOW... I have NO idea what injectors to get. Someone point me in the right direction? PLEASE? THere's a set of 1600's on the "other" forum for pretty cheap... What impedance doth I need?



https://www.nopistons.com/forums/pub...#>/biggrin.png thanks!

what about 1300's i know a few people who are running close to 400 and over who are using 550's and 1300's... then you don't need to upgrade the rails

eh, go with 850cc primaries and 1600cc secondaries.. if you are gonna do it, do it right.

Hmmm... I'll look into that. https://www.nopistons.com/forums/pub...#>/biggrin.png

True...



Now, where do I go about getting the rails and proper injectors? https://www.nopistons.com/forums/pub...IR#>/smile.png

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 https://www.nopistons.com/forums/pub...IR#>/bigok.gif

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



mike

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! https://www.nopistons.com/forums/pub...IR#>/smile.png

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 https://www.nopistons.com/forums/pub...DIR#>/wink.png

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

Ok...Well, the Walboro and the Supra pump are BOTH in my price range... So the better of the 2 I will go for. Now I just have to figure out what secondarys and rail to get... https://www.nopistons.com/forums/pub...IR#>/smile.png

k2rd has the rail, but dont call him today cause he's not there



mike

Hrm... Thanks Mike!

1300 fit in the stock rail. 1600 and up need a new rail

Ok... To my understanding, 1300's are capable of supporting 500hp? I won't be NEAR that. I'm guessing 350-360?

i recommend keeping relatively stock sized injectors for the primaries, go too large on those and driveability/low end/idle tuning is going to be hard to get good.... thats why staged injection is nice.
