Z33+RB26dett=?

[Initial_R90]

what do you guys think i currently have a Z33 i know its been done there's little info on it feedback and idea's would be great looking for some intresting idea's for the future of my car

[Cjmartz2k]

Not worth it unless you just want the "mad jdm tight kewlness yo". To much money for enough gain. You can make some pretty big #'s with the motor you have now. How much do have to spend and what's your goal for the car?

[BoostFab]

why not work with the v6; it's that horrible to you??why don;t you wait and buy the new nissan gtr in 2008 then drop in a rb26 because it originally equipped with a v6

[Initial_R90]

well money wise the sky is the limit i dont buy anything besides car parts i make like 3k a month, pretty much i'm looking for decent horsepower with the "wow Factor" and for people who say it cant be done. There's nothing wrong with my VQ i love the TQ the engines proven, been on top ten best engines for the 5 years it was out but i want somthing race proven the RB26dett stayed almost the same since the late 80's up untill the 2000'sseem's if tho they change somthing on the VQ every year also the VQ is designed by Renault and i'm not to fond of french technolgy anyone know anyone with this swap done i'd really like to talk to them

[Cjmartz2k]

Welp, for that, sounds like you could deal with an RB26. I know here on Okinawa, a friend of mine who owns a shop did it for a guy for 10k, but I don't know if that included the engine/transmission or not. I would assume it did, but i dunno. I'll ask him tomorrow.

I would get the wow factor for sure, but so would a 302 for a lot cheaper.

[Coolwhip]

Screw the RB...Stroke and bore that VQ to a 4.2L and do a massive GT47 or something.

Now thats a WOW factor. And you don't have to worry about swapping motors.

4.2L VQ > 2.6L RB

You bet I would go VQ if I had the money.

[Darius]

You know. I love my RB, but in hindsight, I would have gone with a USDM motor of some sort where parts were cheaper and easier to come by. Sucks that you end up paying $55 for a damn idler pulley after shipping.

The VQ is a great motor for turbo applications once it is rebuilt with forged pistons and rods and with a sleeved block. After that is complete, just slap on a turbo setup and add fuel and tuning to match. That will be wayyyy below 10k including the turbo and engine management, and that combination would blow the "socks" (see what I did there Coolwhip?) off any stock RB26.

[Coolwhip]

you know what they say about those with bigger "socks" you can get more stroke out of them.

haha

[eh?]

For making any decent power I would definitely take an RB26 over the VQ. Sell the VQ long block.. to the poor Z33 owner who poopped his stock long block and use the cash for upgrades.All I need is an RB26 long block w/acc. VQ transmission can stay, wire harness can be sourced elsewhere. Sleeving the VQ is EXSPENSIVE! You're looking at about $2000 to just sleeve the block.

I don't look at the VQ as the future of nissan engines as most people do. I see it as a cost cutting initiative which is probably the truth.

[driftingmy240sx]

i know a shop that did a rb26 into a g35 and only ended up costing (due to many upgrades) 25k. what are you lookg for power wise? ever conside the twin turbo route. the vq motor is what the gt-r motor is based on (3.8 tt)

so in the end you put in $60k; hmmm say hello to M5

[Initial_R90]

hello lotus i know about the TT route getting very popular anyone know the weight diff from RB26 compared to Vq35de?

[StricNyne]

WHAT ! z33 trans works on a RB!!!!

[raremotive]

WHAT ! z33 trans works on a RB!!!!

Yes, you just need a rb bell housing to mate with the z32 transmission.

Edit: Crap, I thought you said z32.. no the z33 doesn't line up, and the bellhousing is not removable on the z33...you can make or buy an adapter for an rb

Initial_R90,

It can be done. It's all about worth and preference.

First things to consider.. are you going to do the work yourself? If so how much you know... if not much then you should stick with something domestic, because parts can get expensive fast if you keep making mistakes and second you should begin learning on a simpler platform that is more forgiving.

Don't get an rb because you think it will give you the legend of the Skyline.. rbs are overrated, you have to understand that skylines are intellegently AWD... and if rb were the end all be all... why isn't nissan pulling the rb in the new GTR... I am sure you heard that they can make up to 1,200 hp, but the reality is that it is not easy to do and very very expenisive to reach the benchmark.

BTW what do you want to do with the car? Drift? Might I suggest the SR20DET if you are hungry for a swap, after modifying the organs of it you will have a platform that bring you 300 to 500 hp which is more than enough for less you would pay to have the rb modded. And your overall weight will be greatly reduced.

And to finish my rambling... whats wrong with the VG30DETT? It has more than enough power, and you can get a complete engine for the ballpark of $2,500 minus shipping.

BTW the rb weighs more than the VQ.

wtf "intelligent awd" sounds like you just read a bunch of internet/magazine **** (you're referring to the new gtr). it's so funny. all the people I know that owns an sr20 want the rb. stock block rb26 put out over 500hp, while you have to do a fully rebuilt on the sr to get close to that. and the rb26 is straight p0rn. how much you know about parts for the rb!! it's everywhere, not sure what you're talking about.

Dan,

I wasn't in the mood to type out ATTESA, which IS an intellegent AWD (computer controlled) unlike always active AWD. Sorry you don't like the way I use that term, and maybe not include why it's about the AWD and S-HICAS. Which involves explaining about Mours Circle and the important contributors on following it...which will steer away from my main point of selecting the best powerplant for his needs.

Second where did I mention anything about parts...and ask me if I know anything.. you assume too much already..

The purpose of the second paragraph is simplely state it is only an overrated engine. I didn't say it was a bad engine, just overrated. My refering to the new gtr is simplely conveying if it was the greatest.. why aren't they using it.. nothing funny about that.

And finally, I am not looking for a feud with you. Just be reasonable and look what the purpose of the post is about.

What evidence do you have that the RB26 is overrated? Sounds like you probably frequent the Drifting forums..

So what if the R35 uses a VQ based VR engine? Three of the greatest cars Nissan ever produced had the RB26. That says enough. Why bring back an engine that went out of production years ago?

*IMO* Nissan is foolish to give the GTR the same engine "base" as the Altima. Not to mention bringing it over as a Nissan and not an infiniti...

Nope, all my posts been here...the engine is overrated, because the amount of people who wish to have it for only the reason of belief of being the best. Nissan don't use it anymore for another(maybe due to harder emission laws, actual reason not determined). I am a person of application, and engine type is all about application. So don't get me wrong, I like the rb too.

But not be offended that I say overrated, it is a good engine, very strong bottem end. But it has it's fair share of issues, like the block is long, so the coolant is hot before it has chance to cool the remaining cylinders. The block is also very heavy, the entire block is made from cast iron, 6 whole cylinder lengths of iron. Between the oil feed being too big or return too small of the head of the engine, oil stays up there during high revs causing oil starvation. The CAS system is belt driven, and within, the CAS disc has 360 ticks which can be easily messed up with a slight flex of the belt. Even though nissan has a fix within the ecu, which isn't nessacary the best solution and can result to other issues. AEM sells disc with fewer ticks to allow their ecu work with the engine, you can also use a sensor from the crank as primary and the CAS as reset. There is more to the list and there are fixes to these issues, but the evidence is, it's simply a motor, what you do to it is what counts.

Ok first to make clear.. the it's R36... because the japanese came out with r35 skyline... which is our G35.... Going with a VQ, is most likely manufacturability... they only have to make one kind of v-6 for all cars, making parts for each different platform the close to or the same. The rb26 is not a FWD platform, making manufacturing time comsuming to make compared the the VQ.

And yes I agree about "base" model

I disagree with the oil feed/drain and CAS issues.

The oil feed and drain works fine on the stock rpm RB26. Its when one wants to go to extreme RPM then they run into issues. Do you have to rev over 8000 rpm in the RB26 to make power? no? but people do.

The CAS issue is not a Nissan problem. It's an AEM problem. I know, I was one of the first to ***** about it. I've owned the RB25 pfc and now aem ems. The Stock ecu and pfc never had issues. The AEM did. I've never heard of a PFC user having CAS issues. I do have the new trigger wheel and everything is good. FYI SR have this problem too and also have a trigger wheel fix.

You got me on the R35 but the G35 is the V35 chassis not R35.

[Cameron]

very good explanation, but N1 oil pump and Jun crank collar FTW.. also doing these steps rid of the oil problem..

Quote »1.Block off one oil feed in the block (RB26’s have this standard)2.Fit an appropriately sized restrictor to the other feed. The size of the oil pump is one of the determinates for the size of the restrictor, ie; a high flow, high pressure pump needs a smaller restrictor. Constant higher RPM needs a smaller restrictor etc.3. Fit an external oil return from the rear of the cylinder head to the sump4. Drill out the oil return galleries in the head and block5. Machine around the oil return galleries to facilitate access for the oil [/quote]but all those issues you stated can be addressed to and eliminated, with money and effort, and who cares about the fanboys who dream of them.. how many of them actually own one.. it only counts if you own one.. the rb25/26 is about as overrated as any other high perf. engine out there..

2JZ, SR20, B18C, 3SGTE, 20B. fads come and go, and Fast and furious ruined everything...

so that statement needs to end..

edit: yes because it all one line, and I was like what the heck!

exactly.. but QFT calling it overated in an RB FORUM, isnt going to blow over lightly with some people..

Edit... you just added there are fixes to this issue didnt you...

[raremotive]

sure, I can do that, or at least not use overrated, it isn't exactly the word I am trying to convey..too harsh anyways...

not a writer, just another gear head

[Cameron]

yea its no big deal. RB's are too expensive for just anyone to have one unlike an SR20... just like how people are into the deep dish trend and want works, but settle for something like sportmax.. Bandwagons and fanboys will always be around like i said. just start telling them that 240s and RB's arent cool anymore.

tell them that NA is coming back.. you will quickly see the intrest in RB's dying.

or tell them richard simmons was spotted driving a rbpowerd 240

[raremotive]

lol, yeah... just do me a favor... don't post any more of his pictures... this is bad enough...

[Cameron]

see its working already.

[duffman1278]

Just stick with your motor, forget the RB

[leesredgt]

i say go for it if thats what you want.If you dont mind putting alot of money into it and alot of work and its somthing you want then do it,trust me, if i listened to everyone about what to do with my cars i would proably be driving a civic or a neon now no offense to anyone who has one.
