E46 M3 Turbo
This thread will be covering my S54 turbo build that is being completed at Bimmer Performance Center. The goal of this set up is not to shoot for super high horse power, but to focus more on a quick spool and reliability. This all started when my head gasket failed between cylinders 4 and 5. The head was pulled and completely refreshed as well as having a thicker Vacmotorsports head gasket installed. I also opted to go with Arp rod bolts and Arp head studs.

Purchased Components:

-GTX3576R Gen 2
-Old style CX Racing 3" core intercooler
-E-boost 2
-Turbosmart BOV
-Precision waste gate
-Turner oil distribution block
-Innovate Wide band
-Vibrant -6 nylon braided coolant lines
-Vibrant -10 oil drain line
-Oil feed line -4
-3 vibrant v-band assemblies
-16" Spal fan with controller
-OBX T4 lower mount turbo manifold

Very nice! I'm looking forward to updates on this. It looks like there is a boat load more space between the block and frame rail on the E46 than the E9X
