I posted a little while ago about if its worth doing this swap. Now my new problem is witch one? The 07s are the ones to go with i here but i cant seem to find the anywhere. The 08+ are on ebay for around 100. should i just keep look for 06-07 or is there almost no difference power wise? Yes i WILL BE GETTING INJECTORS AND A TUNE after all this.

I don't believe there has been anyone who has swapped the 08+ manifold onto our cars, but I can definitely say the 06-07 manifolds are a worthwhile upgrade.




Currently #4 in Ecotec Forced Induction horsepower ratings. 505.8 WHP 414WTQ!!!
Currently 3rd quickest Ecotec on the .org - 10.949 @ 131.50 MPH!!!

I beleieve the 08 model is exactly the same as our stock unit so would be a waste of money.
