after reading the post on homemade or custom turbos i want to try it. i have no experience with turbos. will i need the timer, boost controler, change the compresion ratio, etc.?

 

yes, yes, nope.

 

on low boost no need for a timer.. the only thing a timer will do is help the turbo last a bit longer by letting the engine circ oil and water thru, no need on a homade turbo seeing as you'll see 5-6 psi daily....in fac there is no real need for an intercooler on that psi...................
get a DSM t25, 1g dsm BOV, FMU, ANY brand (i recomend cartech), and a missing link , have some one do your charge pipes and DP and be gooooood to go..
