rb25 swap in z32?

i was wanting to do some research on dropping a rb25 in my z32. im am having a hard time finding information on the swap. any information or links to where i could find out anything on this would be very helpful in my decision on my car.

RB25 has been done by a very limited amount of people therefore there is very limited amount of information. reason being is that the VG30DETT is a great motor and people are not willing to sacrifice it for a "less" capable motor. the swap can be done but most choose to swap in the RB26 if they are going to swap in a RB motor. this swap has a kit for it and everything. if you want more info on the RB26 i am sure you can contact this company and they will have a generous amount of information as i am sure they know much about both motors.

agreed... VG30DETT is a much better motor.

from the threads that i have read and the people i have talked to about the swap the rb25 and rb26 are close to the same engine less the awd and a few hps. and that you can get more hps out of the rb than the vg before you have to rebuild the engine. im willing to pay a little extra, if its not that much more, to swap an rb over putting a vg30dett in my car, just to be different.

You have been mislead about the RB25 and RB26. They are good engines yes but they are not the Nissan end all be all engine. The VK56DE is. But as for power the VG30DETT is a strong engine, no one has tried to push the engines past 700WHP yet because of budget constraints. People push the RB26DETT up to 1K HP because they have the budget. The RB is a very peaky motor, its not a good engine when it comes to power bands... it makes gobs of power up at higher RPMs but suffers at lower RPMs. Unlike the VG30DETT which makes good power at low RPMs and makes better power at higher RPMs. This is part of the reason for the death of the RB series engines. I am a V8 fan personally if your going to swap anything into a Z drop a VH45DE........... BTW my swap is slowly progressing. I have decided to start the swap without haveing a second car. Its more fun to build it in my kitchen anyway.

^what swap are you doing anyways man???

You know Child Services frowns on seeing your kid sitting on an engine block at the kitchen table, one that includes such condiments as ketchup, pepper and 10W30.

i'm thinking vh45de...

not true...6 bolt main helps the RB when it comes to putting up big numbers. VG can make upwards of 1000rwhp but lack of room for those large of turbos make it a hassle in the Z32 body.

the RB26DETT makes 1000rwhp with ease in comparison to the VG. Robert at Z1's car made 1000rwhp+ but the heads lifted off of the block. this would pose a problem.

No.... it wouldn't be a problem.... your lying to us again arent you Jason.:icon16:

Dream: The RB series engines arent THAT good. They are good but not as good as you have been lead to believe, as Hodo said. RB25det: waste of time and money. its a downgrade. a BIG one. RB26: I can see why people would do it, but the benefits dont outweigh the costs. RB26's are VERY expensive to modify. And unless you are going balls to the wall ie 1000hp+ then its not worth it. And given you are asking the question of which engine to begin with, that means you wont be aiming for 1000hp. Stick with the VG30 and spend the money that you would have spent on the swap on modding that. Much better bang for your buck.

However, if you are intent on an engine swap. VH45DE!!!!!!!!! I can't stress much much ass this engine kicks. :evillol: Titanium pistons from factory.... oh yeah... *gets horny*

sorry bout that *throws tissues away*

Anyway, go with the VH if you want something fast now, and later on down the track have some cash for moddifying it, will turn into a monster at any RPM.

Hodo:VK56DE???? Thats a friggin truck motor. Can't rev to save its life. Thats one of the beauties of the VH45de, its a (reletively) high revving V8. Man they sound sweet :) VH41DE revs even higher :P

i say butcher some vh45 cams to work in the vk56, get some stiffer valve springs and there and take her to 8k, so much for truck motor then :D

mm...going all out? in my book...the new VQ37DETT that is going to be in the new GTR will be a modifiers dream. 450hp from the factory simply means that 1500rwhp is going to be seen from tuners with enough cash.

I still reckon the VH45de would be a better platform if going the all out option.
while yes it has 450hp stock, it also comes turboed as stock. If you had a VH45deTT with basic turbos on it, I reckon it would be pulling 450hp AT LEAST. Given it has 320hp hp stock and thats with VERY conservative luxury tuning and VERY restrictive parts on it, ie exhaust airbox etc. Compared with the Vq37dett that has performance specific parts designed from factory.

I would be very interested to hear more about the design and block strength of the new VQ engine actually. That way we can see what it could really do.

The reason I say the VK56DE is the end all engine for Nissan is because its right now the most powerful production engine they have stock. Now if you want to go all out then YES I agree the VH45DE is the greatest Nissan engine. And BTW I have no kids so its all good, and I use katchup packets, its cheaper and they are free from most fast food places. That and they dont get confused with the 10W30, when grabbing and not paying attention.

So far my goals are to tear down the engine and spec/blueprint everything, then send the block and heads off to a machine shop near me to get the heads street ported and cleaned up, and the block align bored and rehoned and cleaned. Then get ARP studs and a few other odds and ends and see if I can find some higher compression pistons to put in on some better balanced rods...... Looking to bump the redline up to about 7500RPM. My over all goal is 450WHP all motor, and 200MPH top end. But thats still aways away.

here is the thing...the VQ37DETT will be a modifiers dream because i am thinking close to 1000AWHP will be seen on stock internals. usually larger displacement will overcome and surpass a smaller displacement motor in max HP created but i am sure the VQ37DETT will be coming with the strongest of everything from the factory to withstand 10lbs of boost and 450hp while maintaining daily reliability and 150k miles+.

VH45DE is already doing that :iceslolan

yep... it'll be interesting to see if nissan has anything extra special up their sleeves for this engine...

which is kind of a reason i'm partial to mazda... they're willing to try things other than your standard 4 cycle piston engine.... example the rotary, and the miller cycle engine... it'd be cool if nissan busted out some mad new technology for one of its upcoming flagship cars

i dont know about different forms of combustion engines but the GTR will have some updated systems and things on it that will possess the latest and greatest of technology. how about an updated ALTESSA AWD system? it will be something different and im sure making AWD not that big of a weight difference in comparison to RWD. i dont know if it has been stated that they will use the electric powered AWD like in the Cube over in Japan but it will be something interesting. i also read that Nissan may be going ahead and using the variable vein turbo like Porsche put into the new 911. it will be interesting to see what they come up with for the GTR. we should know alot more over the next few months. it better be something special for a car over $70k that doesnt carry a European badge nor a corvette logo.

VH45DE making excess of 1000rwhp on stock internals? where? need boost or nitrous to do that and i think the compression is a little high for that much boost and that would be one hefty shot of nitrous. i mean, its possible but i have never read or seen anything about the VH being that strong.

btw: VH is much like the VG and RB, its becoming old news. there will be something better to replace in the next line of Nissan/Infiniti cars.

Yeah the Altessa had some serious flaws, thats why they scrapped it. New technology was always going to be used but the question is how much and to what extent? I am personally wanting to see something that has never even been brought up in discussion. I want to see something that has the same 'wow factor' as the VV turbos from porsche.

I'm with D on the whole Mazda issue. Man they have some funky ideas and they work damm well too. The suicide doors on the RX8 and bringing back the rotory. What champs!

The VH isnt becoming old news just yet, at least not in the same way the RB is. It technologically superior to the engines of its era and no one ( to my knowlage) has really pushed the envolope with those engines in a street car. The 1000hp VH45DETT is in a jet boat built by..... fuck I cant remember their name. Its a nissan tuning company in Melbourne...... Nizpro. That it. I dont know any more details on it. But as far as I know, its stock internalled. Maybe the pistons have been changed but as far as I know it is, or mostly, stock internalled. It probably doesnt hurt that it has awesome cooling due to the abundance of water. Generally a good thing with 1000hp...

VV turbos are old news. porsche just brought them back and updated them. hopefully they will work better this time as far as long term reliability.

btw: what flaws were in the Altessa system. Worked damn well in the skyline as it is known to be one of the strongest AWD systems built from the factory.

of course they were going to bring back the rotary. they had to use some sort of gimic to make their sports car sell and they had to build a sports car to keep up with their competitors. suicide doors...very lame. it just turned an underpowered sports car into an underpowered sporty sedan/coupe. ill take the mazda 6 speed if i want a 4 door car with power from mazda.

so...all of your proof that the VH is a great motor for pushing major HP is a boat that you have no details on that may be mostly stock internalled. i am sure there are VHs pushing well over 1000hp but the aftermarket is so small it would make it hard to build a reinforced uber strong internalled motor just because of availability of parts. i dont think we will have this problem with the VQ37DETT once created.

Old news as far as the concept goes but not as functionality goes. THey havent been used to this effect before and not getting the sorts of numbers Porsche is.

Due to the fact that it doensnt kick in until AFTER your sliding. Cant be assed looking up specifics. Its skyline related so I dont care enough to warrent going back through magazine articles to fine it. Use google and find it yourself if you find it that interesting.

IMO suicide doors look awesome. Each to their own.

Gimme a break. Its not like its easy to find info on this shit.

http://www.nissanv8.com/viewtopic.php?t=4&postdays=0&postorder=asc&start=0

Im interested to see what that pulls on the dyno.

And i know full well what the aftermarket is like on these engines. All I was saying is that the POTENTIAL of these engines is huge. Not that its that easy to find parts for them. An I am sure that the VQ will have a plethora of parts designed for it once its up and running. Thats one of the benefits of having an engine in arguabley the most popular car in Japan.

Oh and btw ALTESSA II is going to be in the new skyline.... How did you not know this?

just spent a bunch of time reading up on the vh45 stuff... yeah, nizpro's boat makes around 1000hp on stock internals....

and 1500hp out of the 37dett? good luck

they look awesome...on a king cab pick up truck. they should never be on a sports car.

if you wanted a break, you shouldnt have posted info without proper proof. ;)

This is the article i found from a quick google search. I read a different article with more details on the AWD system being updated but i cant seem to locate it.

For the lazy:
"If the GT-R does get four-wheel drive, it could use a revised version of the ATTESA four-wheel-drive system found in the R34 GT-R or a radically new in-wheel electric motor four-wheel-drive system. Driven wheels aside, it is rumored that Nissan has contracted with world-famous Lotus to help with fine-tuning the car’s track performance."
http://www.caranddriver.com/carnews/11023/spied-2009-nissan-skyline-gt-r-2009-nissan-skyline-gt-r-chassis-name-and-price-page2.html

so just for review...Nissan is employing Cosworth to help with the build and performance of a 3.7L V6 Twin Turbo motor. Using Lotus to help with suspension and AWD set-up for better track performance. If they can get it to look nice, it should be one hell of a car.

and 1500hp out of the 37dett? good luck
yes, what is wrong with that? the RB26DETT is known to put down 1500hp, why cant a motor with more than a Liter more displacement do it. i look for the VQ37DETT to make over 1000awhp with lack of huge effort on stock internals. for a motor to consistently make 500hp and be reliable, Nissan/Cosworth will be dumping some serious money into the best and strongest of parts, therefore benefiting the tuner.

because it's a v6... the balance in it is way off compared to the rb... as strong as you can make it, it will still only have that 4 bolt main, and that's where the shit hits the fan no matter how strong you make it stock...there's going to be a limit on how much these guys spend per engine... sure if they were engineering it to run drags and track races etc, they'd have all of the bells and whistles... but even then i'm thinking it's going to be limited to around 1000bhp..

nah...new technology. stronger materials but lighter. i will be surprised if this motor will not push 1500hp with your basic overbore, upgraded internals, heavy head work, etc. if the VG can push 1000rwhp, the 15 year newer VQ with .7 more liters should be able to squeeze out another 500hp.

we will see...i have read a few theories that by using the Nismo crank in the VG instead of the stocker it may allow more power to be squeezed out without destroying the main bearings.

also think about this, Robert at Z1's VG is still running today after putting down 1000rwhp. the heads lifted off of the block before the main bearings were destroyed. i am anxious for him to do another dyno run as i dont think he was using ARP head studs.

true, but there's only so much metal can handle... aside from using rare and very expensive metals...

i am excited to see what it will be able to do.... it's going to make for a mad swap engine... good size, hot technology... fancy new stuff... it'll make for one quick 240z once someone aquires the money and time :D

and 500hp at ~10 psi.

my theory: anything making 500hp at only 10 lbs of boost, should be able to make 1000hp with hardly breaking a sweat and 1500hp pushing its upper limits. plus always keep in mind, this is alot of displacement for a twin turbo application from the factory.

as for a swap, as soon as you can aquire the motor and parts for less than $20k, i am sure it would be worthwhile. which until something better comes out, making demand go down, it will be a while. tuners wanting power will still opt for the RBs and 2JZs and LS6s.

i just am excited to see track numbers for this car. with AWD and a handsome suspension and close to vette power, this thing should be able to hang right next to a C6 Z06 around a track as it should as it will be its main competitor for $70k. when i can pick one up for $40k i will consider buying one over a BMW M3. speaking of which, the new M3 should also be a main concern and it is supposed to be cheaper than the Z06 or GTR. :naughty:

i'm just waiting for the vh45 to get big over here and parts to get a little cheaper for it... i mean i can already get the engine, (in a car) for around 6 grand for about 80k on the engine...

mind you the 32 valve thing and quad cams can make shit expensive when replacing stuff... even still...

mind you the 32 valve thing and quad cams can make shit expensive when replacing stuff... even still...

tell me about it...except 24 valve.

as for VH45DE, it will not go in any car of mine until i have seen more people do more with it, better informing me of its limits stock modified, etc. only way its going in my car is i have the funds to build it to the gills and throw on a pair of MASSIVE turbos and just boost the living hell out of it.
otherwise, i will stick with 2JZ.

well, all of the titanium bits, forged steel crank and moly coated pistons... i'm sure it'll go to 600hp no problem... i'd be more worried about the tranny and rest of the drivetrain.

eh...you underestimate nissan. again, referring to the previous skyline, i wouldnt think that they would make it weaker than the previous generation. also remember that nissan is desiging this car knowing that it will be dedicated to the car enthusiasts and tuners. i predict the AWD system being on of the strongest from a factory car under $100k.

perhaps... i guess time will tell

Altessa II system is going to be a electronic AWD setup. They have been testing the system with teh e-AWD on the Titto AKA Versa in Japan. Its a reliable system but I am not a fan of all the new electronic crap going on cars. Give me the heavy metal parts that rotate and I will be happy.


Adding AWD to a Z32 is a task in itself, you have to find a place to mount the front diff, then you have to find new front wheel hub assemblies. Not to mention brakes, half shafts, a transfer case. A new powersteering rack that will fit with all this new stuff. The engine in the Z sits too low for you to fit a AWD system in it currently. Not without alot of Dollar Horse Power thrown at it.

Damn double posts......

anyway. There are quite a few who have done the VH swap already. Most problems have been with that octopuss of a intake manifold. Most people cant get it to fit under the hood of a Z32, but it fits fine in all the S30s and S130s.

yeah, it's probably best to redesign it anyway.... something along the lines of...
http://img227.imageshack.us/img227/8439/importx218ms3.jpg

just less... high... it also depends on what year you go with, if it's the one with the dual lower intake manifold style or the single... i can't remember which one flows better...

custom ftw :D

um....so...it still works and propels the GTR to be one of the greatest track cars for under $100k. how is that a major flaw?

Yes the system works, but not as well as it should/could.

Yes the RB26 can put down 1500hp.... but only if you have $150,000+ to spend on an engine.

Spend $200k on a few 6 cyl performance engines and im sure you will be getting some quite impressive hp... Yes the VQ will be a good engine, but lets face it, Nissan dont over engineer their parts to the extent that toyota does.(VH45de excluded) You could push the VQ to do silly things on stock internals but the thing is, it probably wont last too long whereas on a jz series engine, it will.

my theory: anything making 500hp at only 10 lbs of boost,
Thats what the vh45de does.

i'm just waiting for the vh45 to get big over here and parts to get a little cheaper for it... i mean i can already get the engine, (in a car) for around 6 grand for about 80k on the engine...


?? We get half cuts for $2000 over here.

And K3 I think his drivetrain post was about the vh45de....


All in all the vh45de isnt the cheapest nor the most efficient way to get mass amounts of power for very little money. Thats what the the 2jz is for. THe vh45de is because you want something different ie V8 rumble + scream of turbos :D The new skyline engine will be good. very good. But i get the feeling the whole "skyline hype" is going to blow the whole thing way bigger than it really is. Its happened with all the other GTRs, I dont see why this one would be any different.

half cuts for 2k? shit son out of what? i can't even find an engine on ebay, let alone a half cut...

If you want a truly fast car, stop screwing around with tiny little piddly, faggot ass piston engines. (http://turbokart.com/images/250c18.jpg)

i agree (http://rotaryengineillustrated.com/engine-videos/4-rotor-rotary-engine-in-bmw.html)

Pffft, fuck that lame low revving piece of shit rotorary. Listen to it, it barely fuckin runs, it's worthlessly impractical for anything but a full out race car and it will need a complete rebuild after a full day at the drag strip. Pointless, pathetic and just total crap.

i take it someone doesn't like rotaries lol...

i'll take an n/a r26b any day... stout as ever and make a fuckload of power.... probably not that great on gas tho :D

They're fine for what they are but pale in comparison to what I posted.

true, probably a lot cheaper than that beast tho...

Factor in how much a truly total and complete high horsepower engine build costs, the maintence of said engine and the fact that rebuilds will be regular and suddenly any kind of piston/rotorary/anything else typically put in a car becomes highly cost ineffective in light of the uttely massive performance and reliability gain of the turbine. There isn't anything in the automotive world that could even begin to touch a properly done turbine car.

What about that 6 rotored beast??? That was the shizzle...:iceslolan

true but that thing was a one-off wasn't it? the r26b had at least.... 5 or 6 units built... lol

true but that thing was a one-off wasn't it? the r26b had at least.... 5 or 6 units built... lol

No I dont think it was a one off. They had it listed as an engine you could buy. It would be frigging expensive... but purchaseable none the less. What was it 900hp N/A??

can't rememer the 6 rotor... just remember the 4 rotor was about 700hp... so i'd assume it's probably up around the 1100hp range...

I'll take 2 :P
