Rb20 Turbo Banjo Bolt Size

[Rekin]

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

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

edit;just found out the water feed/return lines were too large for the hiflow; not the oil line.

Sorry for the mixup

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!!

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 So nissan was technically right in regards to an older turbo. (older than r32)

Case closed

Thanks

Not sure what conclusion you came to but the early 1989 r32gtst's came with the smaller banjo bolts.

I know,as i have one.

Yes the 31 nics and eccs have different sizes and no restrictor in the oil feed line as they are not ball bearing cores.

which banjo bolts are smaller? the oil only, or the water only?

the water lines only should be smaller both feed and drain, the oil feed & drain should be the same across models. Hame
