350z/RB26 Swap
Sigh... Here we go. Flame if you want. Before anyone says anything, yes, I know the potential of the vq35hr. I know how much easier it would be to just twin turbo that engine and make the power ill want to make. But that is not the point of this build. I wan't something unique and fun. I have always been in love with the RB26 and what better way to show it than to put it in one of my favorite cars. Yes I have searched the forums. Most people doing these swaps seem to be fabbing EVERYTHING. But surely there is some sort of swap kit? I heard that CMS Performance made one but I have been unable to contact them thus far. Wiring specialties does not carry a wiring harness. It appears that a company called Mckinney Motorsports carries an engine mount kit but the trans mount is for the z32 trans? http://mckinneymotorsports.com/prod_RB-350Z+SWAP 
I would really like to use the rb25 transmission if at all possible. My budget for this build is 20k and for now its not going to make any crazy power so even if everything has to be custom fabricated I wont cry or anything. But with this being such a dream swap I would think that more people would make something for it!? 
If anyone has any info that would be greatly appreciated. Shop links, phone numbers, ect... Everything I have read is pretty outdated and I keep coming up with invalid domains and the like. If I really cant determine anything by the time I get the engine and trans then ill just bring it to a shop like zerolift and have them work with me on the fabrication.

How I view an RB26 swap, would be the same as a 2jz swap, or even less so then the play-out snooZzZzZzzZzze fest of Classy's LS swap. ZzzZzzZzzZzz *wakes up*
A turbo'd HR is just as unique as any swapped engine, as their are hardly any people doing it. More so, I would advise and go as far to say that the HR in stock form is more equipped to handle higher HP than the RB. (From my experience.) Do to higher compression and more liters it will also need less boost to make its power, giving you more torque and less lag.
You are looking for something unique. How many people have TT'd HR engine? Exactly.
Also, see my sig bro

Side note: That's a lot of power and I bet a blast to drive

My dyno is 621whp. There are a few VHRs (same internals) tuned to mid 600s from my same tuner and all running well.
According to a shop very knowledgeable in RB building/tuning, a safe point limit for the RB is around the 500whp mark. They caution not to take it higher, and usually wont on the stock block do to publicity. I haven't heard of a failed car yet from that shop.
I highly doubt a 700BHP estimate is "inflated" using a standard 15% drive-train loss. If anything, it's underrated. You do the math.
To Pengu: I use the "BHP" in my sig as a Jimmy Rustler to some of the bros in Useless thread. As you can see, clazzy is one of them.

I believe Rb's can also have over heating and or cooling issues where you have to make small tweaks here and there when going above and beyond stock levels. From the research i have done when sourcing for a swap it was just general consensus that they are very finicky motors that require very experienced tuners\builders.

yes, as well as an oil pump issue on the earlier RBs, which is one of the first things this shop addresses when they mess with an RB. The engine will fail if these aren't handled properly.
On the last build I saw of this shop, they are so insistent on this mark that they stopped at 499 and change on their tune because it was an optimal tune. The owner felt so ****-teased he brought it back and insisted they hit the 500 mark, 1 more Hp, just so he could say 500whp, to which they did. Maybe finished at 500 or like 502. (Its been a bit since I've seen it)

Orrrr I could upset everyone and do a 2jz swap because there are plenty of kits out there for that swap. How could anyone say that a rb26 swap is boring? Is there no Skyline GT-R love on this forum? I'm a nissan guy before i'm a 350z guy so if I could I would have an R34 right now. Unfortunately I live in America and the laws regarding imports are incredibly stupid. Seriously though that straight six sound is glorious!
