F350 Flipped manifold HE351CW install pictures and some boost/wastegate questions
Hey guys, I recently (finally!) installed an HE351 turbo on my 93 engine. Wow, really impressed with the spool time, EGTs down at least 100 degrees too. Really makes it a treat to drive around town.
I spent a lot of time making a nice bracket for the wastegate, mounted it up with similar tension as the pre-clocked setup. Would only boost 15 psi or so. Pinched the hose off and got 26 psi. I then hooked up a regulator to the wastegate and cranked in the rod at least 4 turns so that it was barely opening at about 27 psi, can boost to about 21 or so now. (has to be some drive pressure opening the gate)
I see a lot of 1st gen guys have theirs tacked shut or wired shut. It seems like a waste (no pun intended) to have a wastegate and not be using it.
Are the 12v just moving so much less air they don't need it? Am I really fueling that little? The truck seems plenty fast to me; seems just as fast on the top end as before, if not better with very little smoke under full load.
I only have mods in sig and full load screw turned about 1 turn in. I just never felt the need to hot rod the thing but I may have to now just to use the wastegate lol.
I had the silencer ring out and put it back as I prefer the sound of the cammed 12v over the whistle, each is own I guess...
Longer oil line and fittings on the way.
I welded my 4" 06 exhaust to the elbow, it is cast steel, but not the best quality. I would suggest pre-heat and 2 passes, 1st one done in 1" increments opposing each other, mixing the steels...
There IS enough meat to bottom tap about 1/2-5/8" here. I went ahead and made myself a guinea pig for others lol

Looks like a nice clean swap. You can buy a machined steel v-band to weld to your down pipe. Looks like you used the early 2nd gen engine mounts in your conversion. I still like using the ford version exhaust manifold but you sure have a huge space for a down pipe with the turbo mounted up like you did. Looks really nice and yes you'll really like that turbo in your setup.

How did you fill the hole where your boost ref line comes out of the turbo? where the solenoid went. I run a spring gate and limited it to 37psi. Nice looking setup you got there.

Thanks stu, I sawed off the boss the solenoid screwed into and filled the small return hole with FIPG. Tapped the housing 1/8" npt for an elbow.
What kind of fueling mods do you have to get 37psi?
Edit: sorry I see in your signature, maybe ill turn up the full load screw now :-)
