V6 vx injectors into a vr how do i change over the regulator

[jharv58]

i changed the injectors over a while back but i didnt bother looking into the regulator should i try and swap that to and if so how can i do that. or is it just a waste of time. cant really find much on the net

[jharv58]

not sure if its right for the vx injectors

[justbad4you]

[QUOTE=jharv58;1763475]not sure if its right for the vx injectors .................. flow rate is smaller (not my much 1cc from memory), but better atomisation. if you drop in the VX injectors drop in the VX fuel pressure regulator too, that will ensure the correct fuel pressure is maintained.
this answers your quetion......change it....oh and good luck....cheeers

[jharv58]

ok correct me if im wrong bt the one in the first picture u put up is that the actual regulator

[jharv58]

cheers i will do that u wouldnt know the part number of the top of ur head would u if not il just look it up

[justbad4you]

lol want me to pop over and put it in 4u( im kiddding) no not of hand ring holden or repco and thay will give it to you...best of luck

cheers i will do that u wouldnt know the part number of the top of ur head would u if not il just look it up

to my knowledge you only have to change the regulator if you put the super6 injectors in (white) otherwise the pressure is much the same. should be at approximately 3bar.

the super6 has more fuel pressure i think its about 3.5bar.

edit: the one behind the TB is a damper. it just helps to smooth out the supply pressure for moments when u slam the throttle shut to stop the lines shuddering.

[VR_Acclaim]

The eco Tec and Buick regulators are different and the lines are pressed onto the vx one correct me if I'm wrong, but they aren't interchangeable,

[jharv58]

so theres no point in changing it. or if theres a point how would i change it and what to because i cant get the one off a vx fuel rail

[wamboin23]

no difference between Super6 and standard Ecotec either.

[VR_Acclaim]

It's the vacc ur motor creates that cause it open allow more fuel back into the tank, not to the injectors, and u would still only be gettin the stock fuel pulse with out a tune, all ur doing is allowing it to run abit richer, also just sompeople are aware the best injectors ive found on a stock v6 and edible 4cyl tr magna injectors the cream ones, as for fitting the regulator all the hoses are bigger and the fitting

so do you think he should get a new 1 ? or save hes $$$ (or is it a case of if it aint broke dont fix it ) cheers

[VR_Acclaim]

If it isn't broken leave it, a new one won't allow more pressure as there not on the in line there on the return, and the injector will only pulse so much, bein a vr the map sensor ran, so u would need a bigger map sensor to accomindate more air/ fuel ratio, which won't be effective unless ur running high comp, leave the fuel reg and do the plugs perhaps? Don't bother buying expensive ones as it's the same with spark ur stock coils will only spark so hard and it won't be enough to need 30 plugs, did u change ur filter? If not do so as urbinjectors may not be workin to full capacity with a clogged filter anyway
