Just for reference this turbo HOLSET HE221W part number 3782376 has a 17.5psi wastegate out of the box.

I would not use the vac pump drain.
There should be some photos on here somewhere of people using the oil pump cover for a drain.
Have you considered other possibilities like the push rod cover, or straight into the sump?
Do you have the cover plate on your block where the factory turbo motors drain into? (that's what I used)
checkout this thread 4BD1T - set for oil drain etc



I think McBrain was referring to the vac pump oil drain on the NA block which goes straight into the block, not via the dipstick tube.

I ended up draining the oil from the turbo to the horizontal oil pump cover plate. However, the factory set up drains oil to a vertical diamond shaped plate a little lower on the side of the block.

That's a neat job. Does it go under the starter and in between the chassis rails.

Goes out throught the inner guard then runs under the sill..where the existing one was. Will hang a bit low and prolly get hit one day..but there's really nowhere else to put it unless the body mounts are scalloped out...prolly not a good idea🙄

Looked at that but would hang quite low under the starter and not much room between the chassis and TC etc..so went out the side under the sill..will look a bit cheesy until it dulls off or gets painted!

Personally I like what you have done. If you go under the starter like some have done it adds extra heat to the bottom of the starter and the bell housing. Going out the original path is the best idea. Just don't put big offset tyres/rims on it and you shouldn't have a problem.

Yeah..big tyres might be a challenge..35s are off the menu now..33s will be ok. Big tyres/big offset loses lock real fast anyway..and there's not a lot of steering lock to begin with😐
