Im helping my friend upgrading his new MY03 STi. Im owner of STi 3 wagon but im not sure about the same upgrades on new Sti.

1) can I raise boost using bleed valve?
2) I found two lambdas on exhaust. Before and after cat. Which effect will be after replacing exhaust without cat?
3) Whiteline ALK and swaybar links. Can I get noticeably better handling?
4) Could mappers (on GEMS, LINK, ECUTEK etc.) use the variable timing on intake cam?

Thanks.

And any suspension upgrades in future?
Are you happy with standard suspension?

CTRnutter

at the mo the suspension is very good it has a tendancy to go wide sometimes under pressure also the shortech kicks in if the tail snaps out to much, I think it is a good compromise for the road, probably look at changing the dampers and springs later on, and then move onto the brakes,

I think the first stage is getting nice reliable power through the rev range. it's a bit hit and miss at the mo as there aren't to many people who have tried modding with this paticular car at the mo so no mistakes to learn from.

ROBO

Keep us all posted how the car gets on CTR. Very interested as i`m picking up my STi 8 PPP soon.

Cheers

I bet you can't wait, it's a real improvement with the PPP alone, it also sets you up for modding later with the Fuel pump and the like
