Legacy GT wagon sluggish winding up

[Guest]

Sometimes when i decide to take off fast in my 96 GT wagon it is a bit sluggish around 2000-3000 rpm. Mainly notice it in 2nd gear and its nt like that all the time. Could it be dodgy distributor points or spark plugs or something?

could be VOD aswell( the change over point is remarkablely noticible), or it could be due to turbo lag(time it takes to build pressure)

+1 thought it was a bit higher.... but in mine it was like time stopped haha

They dont have a distributor bro . . Could be vod as said before . Do you have boost gauge ? Makes it easy to see vod

[Guest]

Havnt got boost gauge yet coz my turbos are factory. What is VOD?

[DRFVDR]

VOD = Valley Of Death = A tuned in 'valley' between the change over from primary to secondary turbo,usually about 3500 RPM,can be made better with aftermarket controllers....

One of the reasons why single turbo conversions are so popular...

Valley of Death - change over point between turbos - aprox 4500 / load dependant

boost gauge < get it

try some of my other Twin Turbo vids

hahaah beat u

aint converting to single turbo lol il upgrade both of them when i have loads of cash to spend on it. For now im just trying to get it to run the best i can.

Should i invest a half decent boost controller to increase performance?

[Joker]

EBC really only two options for the twin Apexi AVC-r and /or Greddy pofec Spec II

both allow rpm specific boost controll

ie lower on primary and higher on secondary / dual stage boost control

Personally I would not bother too much - they are pretty much gimmicks with cool gauge readouts

I'm running a apexi and still not even sure if its tuned proper..

[Guest]

Just did some googling on them. Where abouts do u buy them from?

[Joker]

older units now - keep eye on TM

[WRXONP]

What about those zerosports sequential controllers ? They allow you to change the point of change over dont they ? Vod looks sooo depressing on a dyno sheet what was subaru thinking ?

[Joker]

yes is third alternative - lets you 'tune' crosover point BUT never used one - soem have both the aero sports thning AND boost contoller

[WRXONP]

And theres all ways the alternative of having a singular turbo no more vod

convert to single turb ummmmmm....

NO!!!! lol

Definately gna look into a decent boost control system tho

eventually gonna upgrade both turbos but then have to upgrade intake and exhaust so il wait til i have a bit of money 1st

[WRXONP]

Why you wanting to keep the twins so bad ? Single will all ways eat twin and from what ive seen single is more fuel efficient too

[Joker]

far too much effort unless its proper broken....

mine just ticked over 220,000 km's on the weekend, oem motor, still TT

[Volcanix]

not to mention the cost isnt very cheap

I'm also wondering why such a big NO to single turbo conversion. Also upgrading your twin turbos wont give you much if any of a change, you would be better off with a set of down pipes. You have ti be careful winding up the boost on the twin turbo.

The zerosports controller can be ok be personally i didn't rate mine when i had it.

An exhaust really helps with the twinturbos.

Ive dragged skylines with big single turbos and ate them so i quite like having 2 turbos and the big NO was jst me being funny

Well a skyline is a different story all together

[WRXONP]

Lol . . Put a single turbo sti up against a twin turbo legacy . . . . . . . . . Better yet put the sti against the skyline make em both look like slugs
