xJC350x - Sounds like a cool swap, but here are some things to consider coming from someone who owns a 1995 Skyline GTR vspec.
Make sure your have the R33 or newer crank on the motor you are buying, the crank collar on the earlier RB26's was narrower and was prone to causing oil pump failures which in turn destroys the entire motor.
Also invest in a quality oil pump.
If you are going with a big single turbo take into consideration that with the amount of lag you will have you will need to push your motor harder, higher rpm's etc you are going to run into problems, mostly oiling and cooling, these motors get hot. Make sure you have a nice oil cooler added to your build.
I think you need to own one to truly know the money pit they are, VQ's parts are readily available everywhere and with the RB be prepared if something breaks not only will you have a harder time finding the part you need, allow extra time for it to arrive.
Good luck with your build!

In for updates on this build though!

@ Nexx: from the factory the numbers bone stock on the RB26 are more like 320AWHP on an R34 GTR. Just like the Supra's 2JZ engine people are seeing upwards of 600hp on stock block internals, Reliably. Supra engine are getting 700hp on stock block engines. With a forged internals and head work on the RB26 we are talking like 700-800 reliable wheel horsepower. Crazy Huh? now, I am not saying that the VQ can not do the same thing, as it can, BUT check how much it cost just to get reliable 600 crank horsepower from some big name shops... The guy that owns the shop that is doing my build has direct hook ups from Japan and these guys are laughing at my 500-600hp build, as they are doing reliable 1000hp engines for child's play out there. I m not that guy to say, "take my word for everything I say", but please google it to confirm what I say.
Saying that to say this, 500whp is easily attainable on a stock block RB26, just don't expect that with the stock turbos, as they will grenade at anything above 14 psi.
@ Wasuber: Thanks for the heads up, we are going with a bigger and better oil pan and pump as well as a RB26 built between 2000-2002. I hope reliability won't be a big issue for me and parts hold up. Good thing is, my shop can get these complete engine, not to mention parts, within a week if they order from Japan which makes me feel A LITTLE better, lol. What Kind of numbers are you generating on your engine? Is it stock a rebuilt?

with stock turbos? with stock intercooler? with stock fuel system? with stock oil cooler? with stock clutch? i know exactly what their capable of modded but people who high power RBS and 2JZ's put a lot of money into them. they just dont install a booster control and wham have 600whp... just saying i think its one of those misconceptions.

No none of those items will be stock. There is a lot of money going into this build, but it's not going to be a just a turbo switch and I am ready to go. I am going with a single turbo, twin mount, upgraded fuel system, upgraded oil cooler, upgraded dual or triple disk clutch.My heads and and internals will be the same until either they break or need a rebuild. This build is going to be 15-20k, but so was my VQ build. If it was that easy as to put a boost controller on it everybody and their momma would have this engine. lol

All done in NJ
RB26 into s13 swap (tuned by HKS Sean in Elizabeth)
13B into BMW318TI swap (un-tuned)
SR20 into s13 (un-tuned running 10psi stock t25) for over 2 years
The RB build is my favorite and sounds the most badass. The 13B is the most original i have seen to date.

it seems like a downgrade to me.. your giving up displacement... and the HR can easy hit 500 and daily it. On a STOCK motor. If done right... i see where you are coming from though.. you put too much you got sick of it and the shop screwed you...
on the other hand.. a done right rb26 in a Z is just awesome!! if you say your putting all that stuff you can definitely hit your goal, and have a unique machine.. you dont see those everyday...

That ls2 swap is amazing. I think he runs something like a 10.8 at 132 or something like that at the track. I saw that one on the front of a magazine and was impressed.
Also, thanks for the support guys, I will be sure to keep up with pix, I'll start some pix tonight...

Sounds like you have an R34 GTR RB26 so you should be good. I would highly recommend capping the rpms at 8k or below if you plan on staying stock internals, the issue with going for 600 @ the wheels on stock internals is the rods have a tendency to snap because they can't handle the shock, the block is good, the crank is good at those power levels.
Mine is an extreme build, it put down 777 on C16 back in 2007 with the 720cc injectors and the HKS 2835's with 26lbs of boost flowing through a 4" titanium exhaust.
It did 654 on 91 octane.
Here is a video of my car in the garage, audio isnt very good but thats because of how loud the car is.

Since then the motor has been taken apart again, upgraded multiple weak points and bottlenecks and adding id1000 injectors and AEM meth kit.

Rods as weak point, check. Very nice setup on yours, did you track yours or was it more of your DD? I am wondering if I should do rods a pistons before anything...? But if I stay at about 500-550 I might be ok, you think? Btw, what kind of car was that in and did you do head work on your rb26?

500-550 you might be ok, talk it over with someone very experienced with these motors, maybe SP engineering. they seem to have a great track record with the RB.

Nobody else has asked this so perhaps it's an obvious question, but why drop a turbo from the build?
If you want something really unique, perhaps try a civic engine? I bet no one's done that :P

i would like to do an rb swap, but the facts are it's not a cost effective swap but more of a shock value swap

RB = Run Bearing...I think with all the money you've invested on the built VQ it to late to turn back and plus if you sell ll those parts you'll never end up getting the money you spent for them back...you'd be loosing even more in the long run...I think if the shop wants to use you to "put them on the map" they should sponsor you and give you some kind of deal like free labor or have them do the custom fab on their dime! It'll definitely be an interesting project non the less just be sure to post pics!!!!
