I'm not 100% certain as I've never done a swap, try phoning MV Automatics, they have the best reputation in the country for nissan trannies I'm sure they can advise you.

The modern Bosch EV14 injector should handle idling quite well in a RB20 even 800cc ones.
if I were you I would be going for some of these, with a Nistune they're drop in and decent value...

no apology necessary, some times i'm blunt, some times i'm sarcastic, a lot of the the time i'm just plain rude, i put it down to old age.
oh and I'm not trying to push penrite, in fact i've never used it, though i may give it a try next change.
There is some truth in what he said there in that racing ten doesn't have the latest ACEA ratings like A4 A5/B5 like the Enviro but the rest is complete BS.
Racing 10 does have high zinc (ZDDP) which is good for RB engines especially Neo's and RB26's with solid lifters, oils with high zinc and phosphorous levels tend to clog catalytic converters faster and hence they don't meet the latest standards for petrol/ diesel economy engines designed to run in California with their strict laws.
It's service life is fine for daily driving, hence it's A3/ B3 rating...
For use in high performance petrol and diesel cars and light commercials where extended drain intervals are specified by the vehicle manufacturer and / or for year-round use of low viscosity oils and / or for use in severe operating conditions as defined by the vehicle manufacturer.
...probably one of the better oils to use in an RB!
The correct washers are not the flat type, they're a crush washer. See what your local Nissan dealer wants for one or buy a 10 pack from ebay...

If you're going to spend big bucks on racing fuel, then it would be silly not fork out for a vent dryer, ethanol will pull water vapor out of the air and contaminate you precocious.
