You certainly can. On the other hand, most of the aftermarket turbo kits use a 1/8" NPT port for the oil feed and have no problems at all. It seems like a lot of work for no gain to me.
Maybe a little more oil volume. I haven't decided if I will or not.
Honed the block and checked all the ring gaps today. If I'm going to drill, it will be tomorrow before the final cleaning. One advantage is I won't have to find new line fittings for the turbo when I swap the rebuilt engine into the truck.

Older thread I know, but I have a question about the turbo cooler feed at the back of the block. I'm building a NA block to be as close to a TIDI block as possible. Has anyone drilled and tapped the block at the oil feed hole to the larger turbo block size 1/8 NPT TO 1/4?
really no point for this.
there is a port on the drivers side that gets oil right from the filter.
this is the best place for turbo feeds.
the rear port, i use for a pressure sensor.

FIRST AND FOREMOST THIS IS A BOOB COMMUNITY

THEREFORE, THEY ARE CALLED TIDI'S :love:

TIDI blocks also have larger oil galleys.
TIDI uses a differently balanced crank, which the flexplate/flywheel and balancer is also different.
TIDI also used different material in the valves....
TIDI also uses a different oil cooler

i have Brian Crower PSD rods at R&D right now.

converting your 7.3D is not as easy as you think to make a 7.3T
The oil coolers are different between n/a and TIDI? Whats the difference on that part? I have both sitting in a bucket waiting to be rebuilt and they both look the same

The tubes inside the cooler cylinder are different. More cooling tubes in a turbo cooler.
Nothing you can see externally.

I did it. Drilled and tapped. I let my self get in a position where I need this done yesterday. The beater truck I've been using has developed an ominous tap and I'm afraid it might let loose.
Which means I don't want to take the time to fab up new oil feed lines.
