Ok so I had a search around. The turbo inlet hose had a rip right on the hose clamp on the turbo housing end so I replaced that with a new tomei one. That didn't fix it at all really (even though it had to be replaced anyway) I read the codes and its only throwing P0159 idle air system performance. We had another search around and whilst cleaning and checking the IACV I found that the motor has seized/died or whatever. Manually held the valve in place and idle returned to normal. So I just need to grab a replacement when I get a chance.

The exact same thing was happening to me. I replaced the o2 sensor, changed fuel filter and cleaned injectors but nothing seemed to work and then did a smoke test and found a vaccum leak post maf on the turbo inlet.
To find the vacuum leak, I bought a $40 dollar smoke/fog machine and attached a hose on the outlet and pumped it in the intake after blocking it off. If you see any smoke coming out then you have a leak. I should have done this first instead of buying a new o2 sensor because sensor was 300 bucks haha.
My comments are based on my personal experience but best to get a code reader first and see what is going on.
cheers for the info man. I'll take a closer when I get home. Here's hoping haha

My v7 has just started idling super rough and I have a check engine light. I took it for a test drive today and it seems fine. It appears to only be an idle issue. I havn't had a chance to run the codes yet. I replaced my o2 sensor as it was visibly damaged and the wires were not in good shape. Seemed to help a small amount. I have cleaned the maf and I'm certain I have no vaccum leaks.
What other things could it be? Obviously need to get the codes ran but havn't had a chance yet.

Obviously RE002's and 3's are mad. I had Nexen SU1's on my S15 and they were amzaing! You can get them for $209 and I wouldn't choose anything else now.

Not on the vin plate? What year is it?

Yeah very true, it's one of the easiest mods you can do. It can't go this wrong...

Well height preference, is personal preference. I wouldn't lower it much at all really. The lower you go the less you'll get performance wise from your shocks. If you want to go real low and still hold that perfomance, your gunna have to fork out some decent cash for coilovers. Brand isn't really a big deal, Tein, Kings etc. are all good.

v8 top hats I know fit a wider range of springs and v7 top hats are slightly different, could be an issue there?
-
Yeah but the if the clutch still has a decent amount of life in it, there doesn't seem like any point...
