I did a search, and i could not find any review on this, so I figured I would post. If this has been asked a bunch of times, forgive me. I did not find any info. I searched using the terms "godspeed fuel rail" & "godspeed" but i couldn't get any good info.

I'm currently getting the parts together for my turbo build, and I just got my Aeromotive FPR and it only uses AN fittings, so I was browsing and found the Godspeed & the Cosworth fuel rails. The Cosworth are very expensive compared to the Godspeed, so I wanted to know if the price difference is worth the money or is the Godspeed fully capable of doing the job. So i guess i have two main questions right now.

1: do i really need to upgrade my fuel rail or can the stock one handle a basic turbo kit with injectors up to 600cc?

2: if not, is the godspeed ones tested to work for pretty well?

I have most of my parts together for my kit, so I'm trying to finalize everything I need before the year is over since I have to do Smog this year.

 

I'm running stock fuel rails.... I'm only pushing 6lbs tho....

 

6lbs on what setup though? which turbo are you running?

 

I wouldn't recommend this kit since I heard that god speed came up with a TN replica turbo kit which basically sucks... If you are running 600cc injectors I assume that you are on stock internals. I would stay with the stock rails and fuel system tile I get a decent one such as CJM or AAM.

 

Internals will be stock for now. Once the car is paid off, I may do a motor build. im only aiming for about 400-450whp and running a Garrett gt3582r twin scroll bb turbo. I do still need injectors too, ask I'm looking for deals on any good used set.

 

m running obx rails, tight fitment wth the lower plenum but work great

 

ok here is the thing if you're aiming for anything above 410whp on a DE then keep dreaming.. and do you mind explaining the setup that you want to run "by that I mean the turbo kit style you're looking into... mid-mount/rear-mount/front-mount" as for the injector keep looking on the market place 600cc injectors are listed almost daily.. I did use DWs with my stock engine setup back then.

breaking 400whp won't really be a problem. Maybe i should explain this is going on my Altima, so I don't have the power loss to the wheels that the 350 has in comparison. I'm already putting out over 300whp N/A. I'm asking the question on this forum because the 350 guys have way more experience with boosted applications than the G guys or the Altima/Maxima guys.

But so far, this is what I already have

garrett GT3582R Twin Scroll BB turbo internal WG
front mounted
I have two different intercoolers. Whichever ends up cooling better will be the one I use
HKS BOV
Uprev tune
plenum spacer & BOP
3" exhaust from the Y-pipe back

Due to the block will be kept stock, I'm not going to push the turbo to it's max.

 

the factory returnless fuel setup is good for about 450-ish whp. as for the intercooler, youd want to size it efficiently for your power goals. sometimes bigger isnt always better. it all plays in to endtank design, structure, etc. you can maximize your hp output by running 3" exhaust from the turbo back. it will also increase uyour spool up, more power w/ less boost, etc.

 

I was given the stock intercooler from the Saturn Sky Turbo, and then i already had a Universal Intercooler as well. Once the the main parts are ready, and i start building the plumbing it will be 3" from the turbo back. Just as of right now, it's 3" just from the y-pipe. Plus this turbo is water and oiled cool twin scroll so it is designed for quicker spool. My spark plugs were just shipped out too, so parts are starting to stack up. the main reason I was looking at the fuel rail is because the FPR only uses AN fittings. But if the OEM can handle that kind of flow already, I may just save it for later if i do a motor build and need more fuel. I gotta order my fuel pump soon too

 

If you are interested I have the AAM fuel return system , brand new in box plus walbro 255. Pm me if interested

 

How much?

 

Stock rails will support 400whp. I had 440whp with them.

 

problem is you still have the weak *** rods found in the DE so anything past 400 is a time bomb.

as for the twin scroll comment just because its twin scroll dosnt mean it spools quicker, still depends on A/R size and would have to keep the banks divided until the turbo housing to max what you can get from the turbo for quicker spool or use a quick spool valve.

 

No offense but you fuel comment is wrong. there are plenty of people on this forum pushing 500+hp with stock fuel rails and return less system.

 

You can also do the JWT fuel rail mod (drill out the stock ends) and it will get you >500whp for sure.

 

the diameter of the stock rails is fine, its the ends and the hard lines leading to them. chop the ends off, weld on some -an fittings and have new rails for 40$

 

Second this! All you need to do is drill them out and you will have a costless fix if your concerned about it. This is what I did.
