As title suggests, and either manual or electronic boost controller but manifold is more important
It does seem to be a popular manifold but having just spend quite abit on an emanange and got to get it mapped, want to see if i can get something a little cheaper. Also if i td04 it in the future ideally i dont want to have spent alot on a ct9 manifold.
Well you have a few choices for a "cheaper" one, like the Autobahn or Japspeed but they are rubbish and will crack. You could buy a SPS, then if you did go TD04, sell it on. Doubt you'd lose that much!
