Hey,

Ive recently picked up a hiflow rb20 turbo to put into my 1993 r32 gtst.

Half way through swap-over, turns out that my standard oil feed banjo bolt was LARGER than the hole in the hiflow..

Thus raising the question;

Did the rb20 turbo come with different size banjo bolt?

Is the series 1 (1989-1991) r32 rb20 banjo bolt the same?

Is the cefiro rb20 banjo bolt smaller/larger?

Trying to work out why the hole is smaller :P

edit: the housing has the numbers "16v5" on it.

From what ive read, the "5" refers to the year of production.

Can anyone confirm this?

Also, a bonus question; what info should i provide pirtek/enzed with when making a new oil/water lines.

Can i show up with the hiflow and tell them to match a bolt for the hole + lines?

What length should I get for both lines?

kthnxbye :D

funny you post this as i have had the same problem recently...i have a rb20 in my s13, installed a rb25 turbo, run fine, till i blew it (due to stupid reasons dw), so i looked at putting an rb20 turbo on as they cheap as chips n i only want it for a run around now. I had one from a makes car..fitting it up fine then realised it had a faulty exhuast wheel, btw this turbo came of a 93 modle r32gts-t. So i bought one the other night from a forum, was a rb20 turbo, so i went to install this and realised the water feed and return lines are different! there are slightly smaller. So i rang nissan today they said possibly it was an older model one? $75.00 each of the lines (feed/return) so i opted out there. went to a mobile auto hose guy he provided me the right side banjo bolts and fittings which i used to fit up cutting the original hosing and inserted rubber and clamped. she all good now!! Hame

p.s sorry for the book of a post.

oki, turns out that redtop rb20 turbo's have a smaller banjo bolt. Hence why my silvertop water lines dont fit into the hiflow.

This explains why your rb20 turbo didnt fit your car, as the silvertop rb20/rb25 have larger oil lines than redtop rb20's.

In order to fix, all i need to get is redtop water lines :D So nissan was technically right in regards to an older turbo. (older than r32)

Case closed

Thanks

    • 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 stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not 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?
    • 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.  
    • Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
