316L Stainless, 3mm wall / Schedule 10, Incorporated V-Band & 1/8 NPT EGT Bungs. Flange is surface ground flat. 4.83lbs.

For use with turbos mounted on “hot / exhaust” side of engine. Strong enough to support weight of turbo. Centers turbo between cylinders 2 & 3 Leaving enough room for a decent size air cleaner without hitting prop with no spacer.

Designed originally for the Garrett GTX2860R turbo with V-Band flange and incorporated Wastegate. But could be used with any turbo utilizing this size V-band inlet flange. I am willing to offer this design with alternate inlet turbo flanges and / or an additional V-band for an external wastegate. Contact me for info.


This is the Garrett Turbo used for this setup. All components can be purchased through ATP Turbo with part numbers listed.
