So, what size T is everyone using for their turbocharger oil feed lines on the LD9? Surprised I couldn't find this anywhere. Almost everyone just says to pull it out and go find whatever matches. I just want to buy the T ahead of time so I have everything ready to go Friday...

You mean the size for the oil sender? Its 1/4" NPT.

Yes, the size of the hole in the intake camshaft tower for the oil pressure sensor.

Yep should be 1/4" I believe. Use a fitting about 2" long then the T, it needs to stick out farther than the cam tower.

All this turbo stuff is pretty sudden, bored with the sc already?

Thanks.

I decided to turbocharge last week after a long period of contemplation. (And everything will be running Friday). The MP62 was taking too long (my fabricator, not me, if I could do it myself I would have), and it would still not fulfill what I was looking for. Financially, turbocharging is almost a necessity for my buy/sell situation on the MP45 setup. I handed the MP62 supercharger project off. You'll hear more about that soon, as it is near actual completion now that it is in the hands of a capable fabricator.

I have the oil feed coming out of the stock tower, and the oil pressure gauge on the ho exhaust tower, both are 1/4 npt

You could also get the oil feed from the back of the block on the passenger side.

It is a 1/4 inch NPT thread. Just ditch the stock oilr pressure sender. It is worthless anyhow, plus the angle the 2" extension you would need puts the T at an undesireable angle. Been there done that. Here is what I wound up with.

also the brass extensions have a habit of breaking and leaving threads in the cam tower... just be aware of that
