Hi everybody,
in a bit of a confused mo-fo at the moment.
after getting a hks ssqv off pulsar bobby i used the original vac pipe on top of the original dv, blocked the recirc hose going to the intake tube and then put on the ssqv.
went for a drive and it just wasn`t making a sound.
I then set to work and found, using this guide i found on here, that my vac/turbo hoses were routed incorrectly. this is how they should be, i`ve put in black at the side where they were when i found them on my car:
The three pipes in order (top to bottom) on the air chamber (underneath the manifold):
Top - goes to a T piece in the shape of a "Y". One goes to the fuel pressure regulator and the other goes to the boost pressure sensor located on the inside of the n/s front wing. THIS WAS OK, BUT HAD THE DIVERTER VALVE VACUUM PIPE PLUMBED INTO IT
Middle - goes to the stock or after market dump valve. THIS PIPE HAD A BLOCKING PIECE IN IT AND WAS STUFFED DOWN THE DRIVERS SIDE OF THE ENGINE
Bottom - goes to the carbon canister (black unit above the fuel filter). THIS WAS ROUTED OK
On the carbon canister you have 3 pipes as follows:
Top (thin pipe) - goes to the vac pipe near the throttle position trigger/sensor. THIS WAS ROUTED FINE
Bottom left - goes to a small hole located in your chassis leg and is vented to atmosphire.THIS WAS ON THE BOTTOM BOTTOM RIGHT
Bottom right goes to the air chamber as described in the above. THIS WAS ON THE BOTTOM LEFT
Next step i did was to route the hoses correctly:
So then i unblocked the DV valve vacum line and attached it to the hks ssqv.
i removed the T piece that attached the previous dv line vacuum and put in a fresh piece of hose (now just goes straight to the boost sensor in the wing)
Swapped the hoses around on the carbon filter to match the above instructions.
Next! :?
Went out for a drive and the hks ssqv was hapily chirping away on full boost .
However, on occations when i put my foot down the turbo won`t fully spool until about 3.5-4k revs. It feels like it used to spool lower. once it spools it hapily goes to the 1 bar my hks evc is set to.
It also idles different to before. it hapilly sat at 1.5k before and ticked over with only slight dull popping. now it searches alot more than before. idles hot at around 1.6k but at cold it idles at 1k but the dull popping is more evident.
I changed the plugs, fuel filter, dizzy and leads about a month ago.
fault code check is 55
Any ideas what could be causing it? i`m guessing its something to do with the re routing of the hoses but i`ve triple checked and everything is now as per the guide above. It was fine before i route the hoses right :der:
Could the pipes before have been blocked off for a reason?
sorry for moaning on, thanks in advance for any help
