550 primaries

1600sec

255 lph walbro x2, one to each rail

aremotive fpr, static 50psi(?)



Half bridge w/ a T70 1.15 anywhere from 15-25psi..



Should I upgrade my secondaries?

vosko

enough for 20psi i dunno about 25

at what fuel pressure?

35-40ish for fuel pressure with the 1680's....that works for me anyway.



I run 1680's x 4 now, but plan to go down to 1200 x 4.



You could get close to 25psi, but its all depends on your setup and the flow....A T70 is a big turbo... 25psi on a T70 would be blistering fast

Ok so for a while I will be set, maybe look into some bigger secondaries later on.. I won't be running that much until I can make the drivetrain bulletproof..

Why not go 850/1600?

It's a little bit easier to tune with 4 identical injectors. I used to run 4 1600's with a Supra pump and the stock FPR. I ran 18 PSI and had PLENTY of fuel left over. The 4 1200's that whiplash mentioned would help with the driveability, but like he said, they probably wouldn't be able to handle 25+ PSI too well with your planned setup. You can get the 1600's at a great price from Marren: http://www.injector.com .

Yup!! I got my 1680's from Marren...cheap as hell.



I haven't decided on the 4 x 1200's yet, and my only reason for doing it is for the lower load points and idle....My idle is almost spot on know...



13Bace: Do you run a Wolf EMS puter? I think we've chat'd before....

13BAce

Most people get scared away from the 1600's because of the roughness at low loads and the constant flames, but like you said, it can be tamed. My idle was usually fairly steady around 800 RPM.



I used to have a Wolf 3D 3.1 with a T-78 in my convertible. Now I'm trying to decide on a setup for my 91 coupe. I'd like to try out the new Wolf 3D 4.0, but my friend wants to give me his old Haltech E6S for $200.

How hard is it to modify the fuel rails to run the 4 1600/1680's?



Would 4 1200's be enough for a T04S and a streetport?
