what size.

what size nut and thread pitch is the nut for bolting the sr turbo to manifold?

About $60.00 from the dealership. Trust me…! You can use the bolts off a USDM 1992 300zx TT. They are identical to the red top sr20.

hope this helps, I know how hard it is to find small but crucial parts for a foreign engine!

M8 x 1.25 I believe, I know they are M8 foresure either x 1.25 or 1.5. Make sure you get lock washers too and torque them if you can, when i did the turbo on my car, there was only 2 nuts left.
