so ecotecs have a heavier spring do they?

way longer than a vn one especially when a vn ones been in there for years they get real short

Too long i reckon, the S2 VN & VP EV6 motors use one a bit stronger than the S1 VN which is a good upgrade, the ecotec springs give around 50psi @ idle which is way too much - need stronger valve springs to overcome the extra pressure pumping up the lifter which then means double row timing chain and increased stress on the valvetrain - vicious cycle really- and volume is far more beneficial than pressure

yeah my ecotec is 60psi when cold and about 40 hot at idle

my vp was over 80psi on cold startup was off the gauge it only went to 80psi LOL. 50-60 at idle warm off the gauge at revs it handled 100's of back to back g-tech runs to 6000rpm every gear when testing tunes

thought ide buy some more shit cause i can LOL fuel pressure gauge dodgy electric but i didnt really feel too keen on feeding a fuel hose into the car for now never mind the colour change i know its a little ricer but ill have it on white .and a couple of breather filters for the rocker covers so i can fit my VR inlet manifold without drilling passages in the heads for the PCV valve feeds also got a front facing thermostat housing for it so i have room down the drivers side for the cooler pipework also gives me the better fuel rails and regulator so i can fit my throttlebody out the other side now just sit back and wait for the goodies to arrive in the mailbox ebayaholic nowdays

ebay is a wonderful place

hmm be a shopaholic without ever even getting off yor arse except to go to the mailbox- spose thats exercise

so whats the plan for attaching the breathers mate?

15mm alloy pipe welded in the covers i reckon probably straight up from the top corner so they are high and away from oil in the rocker covers since it wont be baffled in there could get a baffle welded in a corner for them dunno yet probably end up with a catch can at some stage just want them cause the vr inlet install is going to delete the PCV valve

so you obviously have the alloy tappet covers then ?
