epolly. yes the VR38 is a superior engine. For starters the RB26 was designed in the 80s. VR38 about 20 years later so there has been a fair bit of change during that time. The VR38 is apparently developed from Nissans Le Mans engines so it does have a racing pedigree too. it makes 500hp standard VS RB26 280hp. it has a better oiling system. more torque etc etc. so yes it's a better engine.

VR38, all alloy with magensium timing gears, titanium this and that, better oiling, bigger capacity etc. etc. I'm sure if you made the engine uncompliant with current emission laws it would have a fair bit left in it.

You can't compare. The retail on a crate motor for one of those would be exorbitant.

Also there is a guy in sydney, Mark, out at St Mary's that has a 202 turbo powered LJ that runs 10s. He's currently chasing 9's, that thing is a monster. I've seen the pics of his cracked/blown blocks and they would make you cringe. Lucky their around $100 for a replacement block lol

    • 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
