My friend has a honda civic si 99 (b16a2) and buy a garrett 3071, he loves te A/C and don't want to remove.
What kind of exhaust manifold fit well with the A/C ???????

Sorry for my bad english

 

Did he buy GT3071R with internal wastegate, or the one with external.

show a picture of the turbo or a similar picture from the web, so we can help.

 

3071R A/R 0.63, turbine wheel 60mm and external wastegate

 

just use a log manifold its simple, compact, quick spooling and A/C friendly

 

Inline pro makes a sweet cast stainless manifold, I went with full-race for mine. There are bunch more companies out there just don't have experience first hand my self.

 

hey guys thanks for the help, i really appreciate

 

no prob logs are the best for quick spooling anything else is just for looks or for the ability to run a larger down pipe, or to run a divided hot side for quicker spool on a bigger turbo. if you plan on running an open housing I would for sure use a long or a mini ram horn ramhorns are good for spool as well and some of them are A/C compatible just gotta do your research. good luck
