aftermarket fuel rails ???

[atcracing]

hi fellow ls1 fans thinking of putting on aftermarket fuel rails and just wondering if you need a fuel reg kit as well to regulate the amount of fuel that goes in the motor.

What car?
What mods?
What is the cars purpose?

Assuming its a Commodore the reg is in the fuel tank mate. The thing on the fuel rails you see is a fuel dampner. It was removed on later models. So no

vy ss ute s2 pacemaker extactors 21/2 maloo exhaust it has a vt s2 clubsport r8 motor with a generic 300kw mafless tunebut more mods to come in the future and the purpose just to tidy the engine bay up, i have moved the ecu into the cab with plans to move the battery to the viod beside the fuel tank latter on

[Nutter]

Yeah so its pretty mild and running stock fuel system with dead head setup so as above no need for reg......why do you want to change rails? What are your planned future mods?

First thing I'd be looking at before worrying about bling bits like rails is fitting an ls6 manifold seing as you have a vt engine.

Not that rails do anything but the ls6 manifold is hardly leaps and bounds ahead, if he goes forced induction its not worth doing at all really.

why is that macca whats different

[Nutter]

Ls2 manifolds make 10+kw on stockish tuned motors, from memory all vx hsv and all vx non hsv series 2 onwards ran them but I'm probably wrong , also I think vy series 2 went to a slightly higher tension ring set meaning less slap and oil use at at a trade off slight fuel increase and power loss which is never noticed of course because series 2 vys had a slightly better timing map...... With that said I've never checked ring sets from motor to motor, other running changes occurred too like sump baffle changes, AIT placement etc.... Again Knowing what your plans are will help you save money, no point buying stuff you don't need.

Confess they do look pretty, but never yet found any real use for them myself..being more bang for buck motivated

have plans of either fast or elderblock manifold with 102mm throttle body with no2 shot,relocate coils and maybe yella terra roller rockers and otr for this motor, for the original motor thinking 402 stroker,ported heads dual springs cam (not sure on specs yet) double row timing chain with a mp1900 or mp2300 ???

[Nutter]

Am i right in saying your not sure which way your going yet?

What are you planning do do with this car when built ??? , are you aware a well set up cam only is going to be more than capable of blowing the doors off the above setup for 1/4 mile work ...best do some serious research within the forum imho...truly time well spent within, will save you thousands of wasted dollars ...just the mention of YT rockers is going to give me a sleepless night .....Research..Research imho

On a stocker your not far off. Start to play in the modified world and the gains are there. Every little bit helps even if it's only half a dozen kw.. Sure as hell beats fitting a useless set of fuel rails. I'm with mark on this one, no bang for buck so it is purely a bling thing. Better off with a nice set of covers IMO.

I agree 100% fuel rails is wasted money id rather buy 2 slabs of bourbon but with that said if his ultimate goal is FI the manifold is less important...then again i guess these days the ls6 is probably worth less than rails....but as youve picked up based on his wish list i dont think he is sure of what he wants to achieve yet, to me it seems more guess work based on something he read.
