For strictly street use and an AGPT28, BigT28 Killer, Big 16G or equiv (haven't decided that yet), is it better to go with the EVOIII Manifold and O2 housing and port them or just stick with ported stock Manifold and O2 housing? I assume it won't matter entirely because those turbos are very similar in power. Am I wrong? In addition, will most 3" downpipe's bolt up to a the EVOIII O2 housing? Thanks for your opinions!

Just port your stock 2G stuff.

The evo o2 housing has a bigger flange where it meets the dp. So it will take a special dp flange to bolt up. (Its bigger)

Buying another Cast o2 housing is STUPID. Port your stock manifold and get a 02 eliminator like at turbotrix.
