Fuel system for lsa Helloooo everybody, bought a 5.3 and a lsa supercharger, and its going into a 240sx.
So far my thoughts are
-8 feed and -6 return.
Was thinking of using a walbro 255 intank to feed a 2gal surge tank with dual bosch 044.
motor is gen 3 5.3 with 243 heads, BTR stage 2 cam positive displacement, stock lsa injectors.
Just not sure what people run for setups on these and after looking through the forums im still not sure lol

I'm still probably going to do the surge tank for drifting, stock tank baffles kinda suck. just wasnt sure if a in tank pump would support because i saw base pressure was at like 87psi or something.

I'm just saying 1 pump would work instead of 3. But, drifting may be different. I whale on my car pretty good, 13-14lbs boost, and have never had a problem. Fuel pressure is set @65lb. Fast 65lb injectors.

What about using something such as the Holley hydramat? It seems like a pretty simple solution and has a chance at working. I totally get the surge tank as its tried and true, just tossing around ideas. It would be cool if it really worked out for drifting and autocross. 2 Sports I have nothing to do with but I'm always impressed and curious about new tech.

id like to run 1 pump, but when you transition in drifting hard enough, ive had the car cut off and then come back on lol its like half a second or so.
I was thinking about the hydra-mat, I have a surge tank already, but still might give that a go.
Drifting is really fun, I still go to the drag strip too, I like auto-x but in my area there are alot of stuck up dudes. My car previously had a rb20det (2L inline 6 turbo) and they gave me all kinds of **** for bringing it out, kinda took the fun out of it.
@jimmyg are you cable throttle by chance? I need to pick up a throttle body just curious what people like to use.
