Alright y'all im located in the states yes the shitty united states of america that has no cool nissans or commodores etc. Ive been rb20 for the past 1.5 yr with nothing but a tune running 550cc injectors and was reliable at 230hp and 215trq at 12.7psi.

Anyways looking to build an rb22det and be one of the first in the united states. I've done quite a bit of research on this build and i have 2/3rds of the parts needed. Been reading alot of AUS forums cuz you dream boats are crazy enough to try oulandish mad shit and i respect the f**k out of it🤙(yeah yeah i know youre asking why and for the same money you could go rb25 etc but the reality of it is i just wanna be different from the rest and stand out slaying with my underdog build🤷‍♂️).

 Ex: i have rb25 crank and rods already, I still need 6 4agze pistons and. earinga etc. Im also trying to find a reputable shop in or near washington state to do machining, assembly, balancing and what exactly to machine on rods, pistons, block(for crank, rods, wrist pins and pistons to rotate freely). Also want engine completely balanced(like duhh lol). 

Any advice or pointers on shops, assembly, or tuning would be awesome. I am also looking to see what water pump and oil pump to run etc, if there are evn any aftermarket or upgrades from rb20 to run( like i know theres better than stock but i want personal opinions based off of personal experience stating whats good or not and why).Trying to get this heart assembled and rolling by next season. I have rs enthalpy for ecu tuning and access to dyno for tuning etc. 

Im set on this build and already somewhat invested, plus rb20 revs higher than 25 or 26 for cheaper. so any positive tips or pointers would be greatly appreciated. I aint rich by any means just trying to build something out of the ordinary and stand out of the rest showing i can do just as good as anyone with rb25/26/30 or 1/1.5/2jz etc. Ive always love rb and their sound and the fact not many people run them etc

Best regards JankityJenkins

There's plenty of stuff already on these forums about building RB22s.  So have a good search and read what you can find.  Tip, use google to search, not he forum search.  Just specify that you want to search sau.com.au only.

Water pumps are a no brainer.  Just use the stocker.  Oil pumps.....well, there's nothing wrong with the stocker there either.  There are a few people on here who have been sick enough to build RB20s and many build threads showing what they did for pumps, so same advice about searching there.

You are going to want to choose the absolute best turbo.  Something like a BW 7163 would be a good idea.  You need all the boost as soon as you can get it, when there is so little displacement to make torque.

RS Enthalpy's site says that they use Z32 ECUs for RBs.  That is dumb shit for an RB20.  If that is what they're doing for your engine, dump it and get a Nistune board and plug that into the RB20 ECU.  Then it is live tunable, just like aftermarket.  Best value way to do it.

I agree with gtstboy. Especially with the Nistune board. It’s what I have and I got it dyno tuned couple months ago. Made 248whp and could’ve made more if not for the limit of the stock pump. Problem with finding a different turbo is going to be the exhaust housing. Nissan uses a 6 bolt outlet.
