heres my specs

streetport
walbro 255
3in exhaust and downpipe
rtek7 2.1 +(safc if needed)
bnr stage 4 turbo 15 to 18 psi

Should I run 550 or 720 primaries

As for secondaries 1600s ???

Im shooting for 400 whp

Also will I need a new fuel rail and FPR?

 

720cc primaries, 1000cc secondaries minimum.. i tried 1600's but had trouble tuning the transition, maybe if you can find some 1200's or something

 

you wont need a safc since the rtek 2.1 requires a pda for the tuning device.
also i have hit the max of my 1000cc at 13 psi on 35r so id go 1200cc;s min.
fpr... rising rate aeromotive is what i have, i have stock rails but will be getting a new secondary rail when i upgrade to 1600's

 

The idea for the safc was for additional tuning if i need more fuel correction. but thanks for the recommendation.

 

im still using the stock fuel rail and FPR with 1600's.. you just have to take a dremel to the top part to get them to fit. the stock fuel rail and FPR are fine, there is no way a walbro will outflow them

 

Are these what I need?

yep, but they are hard to tune. ever since the load-based staging "fix," rtek does not turn on the secondaries at a set boost level.. so its hard to figure out where to cut fuel in your maps. i would go with 1200's, they should be easier to tune

 

I couldn't find 1200s, so I just went ahead and bought those 1600s. Hopefuly I can get them to work out. Do you have any recommendations for what brand and where to buy the 720s. I saw the greddy ones buy what hoping to find something for about $100 or less each.

high imp so you dont need resistors

 

I just ordered up a set, thanks for the info.

 

I don't think you would be able to go beyond 14psi, because of the AFM(which max out at 14psi). Currently you can't remove with the Rtek2.1

 

You can, you just wont have any fuel/timing tunability above 15 psi...so its not really recommended..

 

could I run an SAFC on top of it for more fuel if I run more boost?

 

So your telling me that I can go 16psi(of course not on the stock turbo) on the AFM if I get the Rtek 2.1 and just get it tune?
