I know the rb26det has great potential and I know it has been mounted on
the 350Z, but my question to every here is it really worth it( time, money) to drop one in instead of going with a forced induction kit made for the 350Z.

I haven't done much reserach yet but I was told that the Skyline motor is much stonger stock then the VQ35, able to hold about 600WHP before needing to upgrade it's internals.

If anyone has any info inreguards to the my question I would greatly appreciate it. thanks!

 

its heavy as hell
and its RB26DETT for GTR swap
its mainly a waste of labor, money, and everything else since you can upgrade the Z for a much cheaper price

 

Your answer is: no.

 

Personally I think the RB's blocks are so much stronger and the reliability of the motor would be better than our VQ's. Even if the VQ was built up, but time and money would be 1 hell of an ordeal if you feel me. If your pockets are deep I say go for it! Another note inline-6's are stronger than V6's! Look at the toyota supra's. I've seen some as high as 1331hp to the fly and they are driven as daily drivers.

 

Probably not but if money was not an issue. I'd do it.

 

He asked if the time/money was worth it. I agree it would be nice if you had bottomless pockets, but if money is any part of the equation, I'd say no.

 

i dont know how much it would cost, so i couldnt say... but development on the rb26 is so much further than the vq35 that i wouldnt doubt it if it was competitive

 

thanks for the info so far.
I have a buddy here in O-town that told me he has a friend that can find the motor for me for about 2500 to 3000 shiped to Miami thats why I was given it a thought.
I also have a friend out in Cali that is puting some serious thought into
this project as well, I think the best thing to do is to follow his progress
and see what kind of turn out results in the end.

 

I would only swap in the RB26 if you are serious about going for 800+ HP (Or whatever nonsense). Reason being that the Z can be built up with forged internals and backup systems etc and you'll be able to (not cheaply) get to 500-600 RWHP.

With an RB25... I actually looked at this awhile back and found afew floating for about 3,500 so the price on the RB is good. Except you have to pull your entire motor out. They need to cut the frame to make it fit, they need to rework the driveshaft position etc etc etc. Or so I am told. Your cost is going to be outrageous. My suggestion is tell us a power number you want to go for. Then everyone is more than happy to give you the most reliable, efficient way to get there (Opinions will vary)

A RB26 350 is sick no dobut. But you're going to spend a ton of money that honestly isn't worth the time and aggrivation. Also adding a turbo already screws the balance of the car a bit. Putting an inline 6 might really make for some whacky balance issues.

True!
my goal eventually is to hit the 600whp maybe even greater who knows, however it sounds like puting in the rb26 in will be alot of custom fabrication TIME in the shop which know one likes and very costly. Not to mention in the unlikely event you blow your motor or God forbid, hit something head on your screwed.
thanks for the info guys, much apreciated.

 

I'm building a S14 with an RB26 and while it's more expensive than the SR20det it is well worth it. It will be expensive to put it in the Z33 but it's a great motor with years of development behind it's belt. If you have 25k to spend then do it. If you are looking to get out cheaper than that then IMO it's not worth it.

 

You'll need to custom mount it (pictures show it mounted with frame rails- esprit 350), custom driveshaft, re-wire your car for a standalone or chipped ecu of some sort, use an RB25 tranny and oil pan to compensate for the loss of front driveshafts, that will in turn leave you needing about 4.10 final drive to compensate for. This will cause you to have to custom mount an r200 final drive or at the very least an 350evo 3.9 final and hope that you can produce enough tq and still have long gearing. That all would probably put you at $8-10K for parts to get it in and be stock, and you still need the custom labor which could run you out the *** if you don't dyi. IMO like others said- it would be worth it if money wasn't an issue, but sadly to most of us it is. As far as weight, with the removal of accessories that need to go when the motor drops in it should be pretty close to stock weight.

 

Definetly not worth the time/effort/money if all you wanted to do was be different. Now if you plan on drag racing the car and needed a better suited powerplant then I can see you possibly swapping out.

RB26 can handle a lot more than 600rwhp with stock internals. There's a clip of a guy in Duabi UAE running a Skyline R34 on full tilt with stock internals @ 9000rpm whoopin asZ on a Hayabusa..If you plan on wanting and utilizing that kind of potential out of this motor then I can see warranting this swap as well.

 

I do crave the high HP the rb26 can produce, however I thought that I might be able to create that HP threw the rb26 motor for about the same price I would spend on the VQ35, so I figured why not be different if it will cost the same.
I don't see myself getting into a mess like that now judgeing by the info I've received here thanks to my350Z community

However I'll be looking forward to my friend droping his rb26 this upcomeing year and see what hell will he go threw.

thanks you all
Later!

 

Id only considering using a RB26 if your purely using the car for the track or for show. The RB26DETT is a real race motor. From the factory it was built to handle hundreds of hours of stress from circuit racing and such.
