The story so far…

I currently own an 86 Hr31 coupe, sporting a RB20DET NICS. Purchased back in 05.

The poor old NICS is a solid reliable runner, I couldn’t fault this engine. Reliability was a major factor for me and I found this engine was great,

Serviced myself. I stood steadfast that it would be maintained un modified. I loved the car for what it was, even choked by the tiny turbo.

Now that my daily driver is a mighty corolla, the Skyline is enjoying retirement and some needed surgery.

The surgery;

Turf the old and in with the hybrid Rb25/30,

Ok so this is what I have so far

1 x Rb25DET out of a S2 R33 1996

1 X Rb30e out of a S3 R31 1990

What I had envisioned was to run the Rb25-30 NA. What I want is more torque, throttle response and a soundtrack from the NA out the back!

Reasons for not going turbo, $$$$$$ and unusable power for a car that doesn’t hit the track, drift or drag.

    • Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
    • Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
    • I also used NP   That’s were it’s seems to be the best place to fit it? All schematic shows also that it’s should be referenced from the turbo housing. But idk, I do see high hp cars without any connection or anything to their turbos, so I really don’t know how they connect their things
    • I do have loctite 243 and 246 and a few more models. I could drill it now in place and make new threads for m12 and order an4 - m12 coupling and fit that to the turbo. Run a braided hose to the EBC which I could get a an4 to 1/8npt 
    • So M12 and sealant should be fine?    NPT ” because that’s what I had and what I could get atm.
