i was just wondering whether anyone could tell me what type of oil fitting if on the block side of the turbo oil feed line. Im just wondering because im soon to be putting on a different turbo on my 33 and want to replace the oil feed line with a full braided line. I want to make up the line before i take the original off the car, because i am limited for garage time. I work with hydrolics at work so as soon as i know the type of fitting on the block side i can order in the fitting and make the line up. Any help is much appreciated

You are after thread sizes and bolt length ? ^R33_KRAZY

There is a Banjo bolt in the block and a straight pipe feed return line that clamps on.

Just have the braided line made up to suit both banjo bolts on the block and on the top of the turbo oil feed line.

If you want any further guidance just shoot me a pm and i will send you a picture to help :P

Ok as promised.

The Oil feed Banjo bolt hole on the block is has a thread of 12x1.25

Same as the oil feed on the top of the turbo.

Water threaded holes on the turbo are both 18x1.5

Water threaded hole on the block is 13x1.5

Oil lines are quite easy , we used to buy -4AN mild steel weld on fittings drill them to size and braze them to a short section of the original steel pipe at either end . Then its straightforward to make up braided line with female -4AN fittings and join it all up . Have to support the line properly off metalic things .

      Baron's R34 GT-R build thread - car in Japan for 5 years -_-

      By BaronOBeefdip · Posted

      Hey, it's a GT-R, it's just as significant a moment as mine😁 It's not ideal when things are uncertain; I'm the type of person that always has a set plan for things in life so being unsure of this plan puts me in a weird place mentally.

      Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?

      Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card style AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had no flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).

      So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?

      Lets play a game - What is causing my oil consumption?

      By tsuokun · Posted

      Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.
