Hi

OK I've searched around for a long time now on various forums and I'm going around in circles with differing views.

I just need a definitive answer ;)

Firstly, the engine (early model RB26) is on an engine stand at the moment. For peace of mind I'd like to replace the oil pump and water pump while the engine's out of the car.

Can I do these myself?

The water pump part should be easy ... just buy an R32 GTR item from Nissan and replace there on the stand. I won't bother with an N1 item as I've heard they're for constant high rpm usage.

But with regards the oil pump, I've heard people say "buy a JUN collar" or "weld a bit onto the end of the crank". What is the best option here?

Should I buy a standard Nissan oil pump and then buy the JUN collar as well?

I've also heard perhaps to buy an R33 N1 oil pump?

So confused!

Any help/tips/hints would be massively appreciated :D

Cheers Morgs - I thought you had done something along these lines so was kinda hoping for a reply from you :(

So basically I need to buy :

R32 GTR water pump

R33 N1 oil pump

JUN collar

All bolts straight up ?

Will it be possible for myself to do the job or will I need a workshop to do it?

Bearing it mind the engine's sitting on a stand.

Thanks !

Julz. Take the crank to sweeting & deeney to have the crank collar made and welded on. Is alot safer than using the jun collar as it cant move , not that the jun collar should move but it could happen. I have the jun collar on mine.

Cheers dude I might give that a go instead! :)

      Yeah based on old XRC5964S specs, it looks to be roughly GTX3576R sized? But this 5964S compressor will flow 90lb airflow somewhat similar to the compressors in both the GTX3584RS or G35-1050.. I fully expected the 0.64 rear A/R to choke up top - seems way too small from typical convention - but these are seemingly beneficial over the prior 0.82 results.. Be interesting to see if he comments on the EFR question in that thread - he mentioned in a prior video that BW EFR's were the "cats pajamas 10 years ago", but by the sounds of things all his kits have been using Xona for quite a while now.

      Yeah it’s still got the oem manual gearbox and clutch, only kinda mods are a blow off valve, coil overs, and a aftermarket intercooler. Also had it for about 2 months now with a lovely midnight purple paint on it.

      Yeeeppp, been following a lot of the testing on the latest Xona stuff and there are some mental results.  He also went over 1000hp @ 4 hubs on his Mainline with a XRE6364S (63mm) which was also well into the 20psi range before 4000rpm on a 2.5. Crazy stuff. Fwiw the XRE5964S is basically the modern equivalent of their old HTA3582 - would drive nicely enough on an RB25 or 26, but proven capable of a huge amount of power if you want to spicy with rpm tho even at sane boost levels will make stout numbers

      The axels in my R33 seem tired, and have a bit of play in them. I cannot find any new of course, not interested in buying used, but I am looking to see if anyone can identify some cross compatible axles. In the states I have seen suggested for S chassis the J30 axles, however for the skyline (as best I can tell) the lengths are about an inch off (2.5cm) on both sides. R33 my measure L 22" R 24.5" GPT L 22.5" 24.25" J30 L 23.5" 25.5"  so shaft length is probably an inch wider. Not sure if someone has another still remanufactured option besides the J30. I figured worst case I can buy a pair tear them down and swap the center shaft. My other option was reaching out to GSP to see if they cannot piece together a set, since the axle stubs are still manufactured, I wouldn't think it be that hard to find a shaft or make a shaft work.
