R33 Na To Turbo Conversion, Help Needed With Oil And Water Lines

[J3TR33]

hey need the input of turbo gurus here..

im doing a turbo conversion on my R33 and just wanted to know answers to a few things.

Firstly is it better to t-piece the oil feed line from the oil pressure sender or tap n drill?

How many restrictors would i need, and what size are they?

Is the oil return already on the NA block or would i have to weld a fitting on the sump?

And are the provisions for the water lines on the NA blocks or do they have to be t-pieced as well from somewhere?

Any feedback or answers would be greatly appreciated. Thanks

yeh but myne didnt have the oil feed line bung at all.. myne is a series 2 engine.. but dnt think that makes a difference. and the rest of the lines we didnt bother looking into caus we had to figure out how to get the oil feed line first.

Just tee it off the oil pressure sender, there is a big thread on this in naturally aspirated performance
