Boost Plumbing v2

[tydon]

On my v2 wrx it has 3 port solenoid everythings plumbed correctly but

because it has a aftermarket fat tank the bottom boost line (off the boost solenoid the 3 port one) usually plumbs back into the fat tank. it has nowhere to plug into and is just venting in engine bay. is this ok?

or do i need to plumb it some how

[Roo]

It\'ll be fine, won\'t even notice a difference

but if it\'s going to do anything it\'ll run ever so slightly richer

[tydon]

hmm have noticed car is a little hesitant on boost at full load.

Ive cleaned AFM. checked for leaks seems everythings good.

although the factory bov had been venting to atmosphere (and was leaking chronically) cause the black pipe was stuffed but since then ive replaced it and plumbed it back in.

No CELS

[Roo]

Checked plugs?

[tydon]

thats next it just hesitates and spits a little bit lol damn it spark plugs so exspensive lol

[Roo]

Not really? $8 a plug for copper cores. Don\'t bother with iridium/platinum plugs

[tydon]

whattt where you get them haha

[Roo]

Repco? What are you paying for them? I get them cheaper again on trade price at $3.45 each lol

[tydon]

do you know what type i need?

[Roo]

BKR6E

[tydon]

awesome as do they need gapped etc?

[Roo]

Yeah I gap mine to 0.65mm which is probably a bit small, might be better off at 0.75-0.85

Haven\'t really experimented with plug gaps but somebody else might have

[tydon]

how do you gap them lol?

[Roo]

Feeler gauges, get yourself a cheap set. Bloody handy

[tydon]

think thats me tomorrow then haha lol so these copper spark plugs are they as good as platniums or iridiums

[tydon]

so i you just use the feeler gauges get the right size and put in between and use a clamp to bend it in?

[filthyrich]

They work the same but dont last nearly as long.

[filthyrich]

Check the coilpacks for cracks when you pull them off

[tydon]

aw sweet as thanks theyll do untill i get some goodies

[Marky]

With plugs the numbers at the end tell you the gap

For example BKR6E-11 means a 1.1mm gap, BKR6E-8 means a 0.8mm gap (means you dont need to try and gap them yourself - I just tap it gently with a hammer haha)

Bascially - smaller gap means less chance of spark blowing out with boost (easier for coil to arc and create a spark) but wider gap in theory means a better ignition, smoother running

TL;DR - 0.8mm should be fine and normal copper plugs are all you need, iridiums or whatever are a waste of cash unless you are changing plugs every 5 thou

[tydon]

thanks marky u da man haha 8)

much easier to go in ask for

BKR6E-8 than to regap em awesome

[tydon]

soooo new plugs and replaced a coil and shes running good accelerates nice no hesitation..

then it came it hesitated and i held my foot down and it dissapeared.

so it comes and goes now.

also had a slight problem this morning went to out for a drive started nicely before went to jay car to get some wire came back out and car wouldnt start.

it would just wind over wanting to but not firing.

took sometime of tryna turn it over and finally started.

LOL.

MY best guess would now be to change fuel pump next lol that and fuel filter

[Roo]

Yeah get a walboro for future proofing, even if you don\'t do much with the motor at least you know you won\'t run out of fuel.

Recheck the plugs and see if they\'re black as fuck, sounds like fouled plugs when it won\'t start like that. A few times i\'ve fouled plugs, replaced them and fouled them straight away again it\'s weird

[tydon]

really?

just before i gave it a bit of boost it hesitated and then spat a cloud of black smoke out exhaust lol.

then ran fine.

i did put injecotr cleaner through it aswell

[tydon]

i put new podfilter on it aswell otherr one was abit dirty still doing the hesitation thing.

comes and goes sometimes it really hits boost hard in 1st other times it wont.

gotta put gauage in see what boost its hitting.
