-what is the stock exhaust size ex: 2.75" 3"?
-Is the BOV recirculating or VTA?
-is the stock suspension decent and are there coilovers out yet?
-Will the intercooler need to be upgraded?
-what PSI is the stock turbo running at?

as i said pretty basic. just want to know what im getting myself into.

thanks guys!


I'll try to answer your question's........but you'll get most of them answered by reading shiv's threads.

Stock exhaust is 2.25
Stock turbo is running at 3-5 psi from 1000-4500 rpm and them 8.5 above 5k (i think)
Shiv has a modified piggyback (xede) with 2.5 catback putting down 333 RWP and 360 RWT. I think he upped the psi to 8-9 throughout the rpm range and up to 10-11 above 5500 rpm (?) Shiv says at the power levels he's running the stock intercooler is fine.

I don't know anything about suspension but I do know the e92 is running track times identical to current M3 (or with split seconds) so it must be pretty good.

I don't even know how bov's work so I'm sure someone else will go over that.

Hope this helps!
