I recently bought a jackson supercharger and am using my stock fuel rail. I'm guessing this isn't a great idea? Can anyone give me some advice on what kinda fuel rail i need or atleast new injector size

your stock rail should be fine the turbo guys use a stock rai and it works just great

and for your injector sizing question that comes down to what you are at now for power and where you want to me doesnt it we cant answer your questions until you tell us what your current set up and specs are

i always use that to tell me what size of injectors i need.

Unless the stock rail is seriously restrictive, i wouldnt worry about it.

for what car and what kind of fuel management?

for most hondas with a JRSC you will be hard pressed to max 550cc injectors.

if you are going to RR-FPR then stock is fine..... well sort of...

For the minor money involved (150 bucks or something) I upgraded to an AEM fuel rail. You're in there working anyways, what can it hurt?

I wasn't sure.

Just rippin on the car today and broke off the A/C tensioner pulley bolt. Car has way more low end power.

DSM 450s and stock fuel rail.

You definitely do not need an aftermarket fuel rail.

What are these worth? Also what is the issue of putting bigger injectors in say 650 or whatever?

Kinda jacking an old thread, just wondering if you can put a JRSC ment for a non-vtec motor and putting it into a gsr, if so what would I have to change to make it fit, different manifold? :/ any ideas? Just found one for cheap so I wanted to see if I can modify in any way to make it fit or just go looking for a different one.. thx

No need to "jack" a old thread, you could have just googled to find your amswer.

Btw He has a b16a jrsc, if you have a gsr you need one for a gsr and if you have a b18a/b/b20 (non vtec ) then you need one that's for a b18/b20 However the b16 one can fit a b18c5 + b16b
