all they have for stock index is 2 small removable drift pins on the compressor and exhaust housings, clocking any which way without interference with exhaust manifold,

 

Yup, as said above the two pins (on each housing) get removed and then you could turn the center section to get the oil holes in the vertical plane. You still have to address the WG though if you cannot use the stock compressor outlet in the stock location.

I have never really seen a back to back comparison of a he351cw with a 60mm H1C with larger housing. I only go by the info others have posted, some have run both and noticed differences but not a real back to back test.

The 351cw may work well on your motorhome especially at only 250HP.

 

The 351 is better then the 60mm h1c. I had the 60mm on the 90 with a denny t some fuel screw. The 92 just got a he351. It has a lil fuel screw, pin rotated and some timing.

The 92 feels like theres no power- like a gas truck. The 92 is way faster tho overall. It pulls harder then the hx 35 I just took off it, just doesnt have the hit like the hx 35 or the 60mm h1c did. My super 40 pulls like a normal turbo too.

I dunno why the 351 makes it feel like a gas truck. It sure does drag my trailer faster tho


Oh yea I ported the exhaust housing too. So that might be another reason it runs like it does. Far as boost and egts - um what gauges?
