evo III 16g and o2 sensor

[b11dragone]

My question is do you have to get the evo III exhaust manifold and o2 sensor housing when you buy the turbo, or will it work with the stock manifold and o2 sensor housing? the reason i am asking is because i have read that the evo III o2 sensor housing doesn't line up with the downpipe correctly. If this is true how much would my apexi downpipe have to be modified to accomidate the evo III o2 sensor housing. Thanks.

The evo III exhaust mani and o2 housing are not necessary in order to use the turbo. You'll probably want to port your stock stuff while you have the chance though...

The EVO III stuff is just the best flowing STOCK parts for our cars. You dont need an EVO manny but it would be nice to have. The same for the O2 housing. The reason the O2 has a hadr time fitting to the stock DP is just becasue the two studs are father apart becasuse it has a larger diameter out let. It is 2.5 (I believe) as compared to the 2.25 of the stock. It should bolt up to most aftermarket DP becasue that have elongated holes to compensate for the exact differance we are talking about.

So no you dont need it all to work, but it will perform better that the regular stock items.
