evo 3 turbine housing swap to b16g. any benefits?

[ed1380]

like the title says. I have a big 16g with the stock turbine housing. My friend gave me his turbo that has the evo 3 turbine housing. I know they'll swap over but will I see any benefit?

Thanks

his turbo is seized, hence why I'm not just using that

Increased turbine flow, possible boost creep if you're trying to run a lower boost level.

If you switch to an Evo III turbine housing you'll either need the matching Evo III o2 housing or you'll have to port the shit out of your stock o2 housing to match the outlet of the Evo III turbine housing....it's almost 1/2" larger than the Big 16G's 7cm turbine housing outlet.

Whats considered lower boost level?


I would get a evo o2 housing, except its at a different angle and theres a big headache getting a downpipe to bolt on to it. any idea about a tubular o2 housing?

Under 20psi.

The angle of the housing isn't as big of a deal as the bolt spread for most downpipes.

The worst fitment I've seen with an Evo III o2 housing was on a buddy's 2G using an older Megan Racing downpipe. The flex section was right at the transfer case and made for a very difficult installation even after smashing the flex section flat a little on one side. I believe Megan improved this on later downpipes.

I'm going to be getting a 2.5" o2 housing. That should match up with the evoIII turbine housing.

I cant really port the aftermarket o2 housing, so how would I deal with the boost creep. I'll be getting a 2.5" or 3" turbo back exhaust
