Im going single turbo at the end of the summer and my injectors are maxed out right now so Im upgrading to 1600s. This is the setup I designed. Any comments will be appreciated:

 

Why not go with a parrallel setup? Then you could use the second port on the FPR.

ive read the archives. I dont need the parallel setup right now and its a lot more expensive

 

so does your setup use the stock rails?

 

What you show will work, just a few comments:

I'd consider at least feeding the rails in parallel using a -6AN y-fitting. This is what I did then tee'd the return from each rail to the regulator.

If using the stock secondary rail, one end is already threaded for 12mmx1.25 (commonly available adapter fttg.)

Talking with Kinsler about pressure drop, they told me to avoid banjo fittings or close turn angle fittings - if possible.

I agree with Trout2. Use a Y or T pre- fuel rails. Run the fuel through the rails and back to both sides of the FPR. I would use as few 90degree angles as possible. Be careful when you tap the primary rails. There is a clearance problem with the oil injectors.

Good luck.

That's some EXCEPTIONALLY fine lookin graphics you've used!! Sure seems like I've seen those in another life...


Anyways, just consider a few thing:
- total fuel flow at what pressure
- potential pulsation problems depending on your injectors' size/arrangement.
- As has already been mentioned, minize the acute plumbing angles.

 

I stole the graphics and rearranged them

Im using 1600s and dont have oil injectors. Thanks for the comments
