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 :D 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
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
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 :)Quote:

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 :shock:...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 imhoQuote:

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.Quote:

thanks guys for the advice on fuel rails will save my money, wanna build a fast street car thats not a weekend driver any suggestions on what to do first keen to save money and do it right the first time thanks. without sounding stupid what does IMO and IMHO short for
I think imo is in my opinion. And imho is in my honest opinion but im old and have been wrong before.
Suggestions are easy..what time do you time do you want to run?
im chasing around 350+ kw
Yeah fair enough....to do what with? Street? Strip (be realistic its for your benifit)? Touring or circuit use etc
350rwkw on an alloy block would require big cam, big heads, big manifold, big primary 4 into 1s (ground clearance issues), fuel system, clutch or highstall + auto rebuild, tailshaft donuts, shorter diff ratio etc etc, if you go supercharged as a minimum you have the kit, ideally should run bigger pipes anyway, you will need the driveline looked at but driveability will be better by a mile with the charger. Of course you have more chance of breaking a ring land, the hight static comp and boost dont play for long on stock bottom ends, not to mention the extra load on tbe crank can contribute to crank and or block failure sooner rather later...too many variables and not enough info from you yet, i know these days people talk like 350rwkw is chicken shit but achieving the power isnt even half the the goal.
You need a realistic goal and purpose for this car to be able to do things right the first time.
Sorry i just saw 350kw are you only talking engine power here and not at the wheels?
engine power? you can get over 350kw at the engine with exhaust, intake, cam and tune
