MHI External Wastegate O2 Housing

$399.00

An MHI O2 housing made for externally wastegated setups that are also looking for some increased exhaust flow. We take a more involved approach to make the most out of the small space between the factory flanges while also offering options for all of the various 1g/2g/fwd/awd DSM and Early Evo O2 housings so you can still utilize your existing 2-bolt downpipe.

Flanged for an external 38mm MVS or 44mm MVR wastegate (please specify) and for a 1g/2g/GVR4/Evo 1,2, or 3/Colt etc (please specify).

Includes:
-O2 housing flanged for your choice of wastegate, O2 bung, and outlet flange style

 

We will be offering a recirculated option, and a version for internally wastegated setups soon as well. Once we build some we will have a better idea on cost/price.

*As of Jan 23 2024, a batch of flanges have been ordered with a lead time of 3-4 weeks to cut yet, so placed orders won’t be able to started until then.

Description

  • Direct bolt-on and exact fit for 1g/2g/FWD/AWD DSM and Evo 1-3, built to be compatible with downpipes meant for your factory O2 housing
  • Tight but well executed 2.5″ bend that isn’t sharply angled off the flanges, and maintains a consistent CSA throughout
  • Exact wastegate position that we’ve found to clear any configuration, giving the most radiator clearance possible with a larger MVR wastegate while clearing a 2g/Evo1-3 alternator stud throughout the alternator’s entire adjustment range.
  • Outlet flange threaded for M12x1.25 factory studs, with outlet angle and bolt spacing tailored to various 1g/2g DSM and Evo 1,2,3 options
  • Factory O2 bung or wideband (heatsink) O2 bung available (only room for one or the other)
  • Most common with 38mm MVS or 44mm MVR wastegate provision off the O2/turbine housing, with other comparable wastegate flange options available if specified.
  • 100% 304 stainless steel, 100% backpurged.

Price is without dumptube. With dumptube is $460 total plus shipping
