Posting with a new account, as my old one isn't much of a loss (hhspunter).
Been working on getting my e30 running again after a few years decommissioned due to a mostly-dead turbo and procrastination. Snagged a used HE351VE on Craigslist a few years ago with dreams of stuffing it into the e30, and quickly realized it would be a big project due to the... big turbo. For those not familiar, it's from he 2008-2012(?) Dodge 2500/3500 with the 6.7L Cummins. 60mm compressor inducer and turbine exducer, if I measured correctly, so not a giant-power turbo, but physically enormous due to the VGT nozzle and actuator.
My M20 is essentially all stock parts, save for head studs and a Enem Z45 turbo cam. The goal with this setup is to make good power on reasonable boost (1bar or so). The cam helps a ton with that from numbers I've seen, and I am hoping the VGT gives a bit more. Depending on who you ask, the nozzle area can change from a couple cm^2 to 25cm^2, and the compressor is pretty similar to HX40 I think... So compressor should be somewhat reasonably sized, and the turbine will get the turbo to spool about as aggressively as anyone could hope for, but most importantly to me, get out of the way and improve VE up top.
The major challenge: the size. Here it is next to a Mistubishi 20g, the turbo I was running before:
