iv been looking all over the internet...and i cant find answers to my questions... I only have 2.

1. Is this even possible? I havent heard NE one else talking about this...only about putting the engine into a 240sx.

2. How much should i expect to pay for the engine+tranny+other swap nessecities.

Thanx

I have always been a Honda guy...so I am a Nissan n00b... I was just drawn in by the sexy styling of the 300zx, and the l33t power of the rb26dett

1: Anything is possible
2: Be prepared to cut your arm off as downpayment

it would take a lot of work to do this, i believe you would have to chop the frame and extend it because the Z's have a V6 and not an I6,

Believe you should check back issues of Turbo & High Performance magazine archives. This was done already in Australia and no costs were published. Also pose your question on the Z31.com message Board. I believe you will get a few leads.

cool...

where can i find teh back issues of T&H? cuz i would really like to find sumthin that could help me here. to my belief, a rb26 powerd 300zx would be unstoppable in my town, as i heard the fastest street racer here runs 12.9's in an MR2.

BTW .... im looking to do this in a 90's 300zx, as i like how they look.

also, i was wondering...doesnt a 240sx have an I4? if so, how do people put an rb26 in one of those??

just wondering, because if the 300zx falls thru or looks to be too expensive, i still want a rb26 ;)

yeah the KA is a four but the engine bay is big enough to hold one i have seen it done before theres a guy in japan who has one and has a site about it i rember there being a guy on www.twinturbo.net having one i forget but it is possible but u have to spend some chese doing it the rb26dett alone last i check was about 8 g's engine and trans and im talking in the z32's not the z31's in the z31 its a lot easier and my and my friend are in the process of doing the mod.. we have a shop to work in but i know its gonna be hard.... good luck with that...

actually it would be easier in a 280 cuz i think the 280 is an rb seires non turbo motor... and its a straght six and its the perfect size...

the rb26dett can be put into a 300z without extending the front. I have seen pics with the engine in the car. what they do is they take off the front shroud on the car. then they put the cylinder line starting where the air intake used to be and it fits into the car. there is a website in japanese of course that gives you instructions and pictures on how to install it. I dont remember the website but i have it written down and i will reply back with it. I dont have it traslated yet but if you could find someone to do it im sure its one of the best sources. You can save money if you buy the rb25dett because the rb26 is 4 wheel drive while the rb25 is just rear wheel. That way you wont have to spend all that money on parts your not gonna use for the rb26 and im pretty sure that the rb25 also comes in a twin turbo model.

for Z31s the RB25DET & RB20DET are better choices for the the converstion..iv seen it done many times. As far as the the Z32 the RB26DETT would fit as well as the earlier Rb engine models. basicly any of the fairlady z series cars can fit the RB and SR engines. but like any converstion or swap..you need to dump alot of money and get custom fabrication in order for it to work. With money, anything is possible.

man i bet swapping for an RB26DETT would be at least 15Gs. Clean, low mileage Rb26DETTS imo would cost at least 8Gs. and the RB26DETT is an AWD plus an i-6 so it would be almost impossible to swap it. but i definietly think its possible.

But why would u want to swap for the RB? I mean the VG30DE(TT) is a creamy smooth engine. Work with what you have. The z32 tt using VG30DETT have alot of potential and the NA version can be converted to turbo. So i would recomend working with what you got. It would be cheaper and you can make more power to cost that way.

alright...thanx guyz...ill take all this into consideration, and the 15g's that was estimated is a lot of friggin money, since i am on a high school (soon to be college) budget. First ill get the car...then ill decide what to do with it...but definately a big thanx to all you guyz ;)

me and a friend are in the process of finding and restoring a z31 for this purpose found an engine and trans for 10 g's.. so thats just engine trans not the awd system (i think the acronym for it is ATESA?? i forget what it stands for but it means i go freaking fast sideways into corners LOL j/k sorta...)

unfortnatly the 15 g estimate would be way to high...the 200ZR and and 300zr (z31 J-spec) came in a variety of engines..as well as the RB20DET.. since all Rb series engines are I6..and not all RB series engines use the AWD system. its very possible for you to swap in a RB26 into a Z31 without dumping 15k into a car. All you really need are the motor mounts from a 200zr, the correct oil pan for ground clearance, the Skyline GT-S gearbox, and a relocation of the turbo. Dont want it rubbing against your engine bay frame. for installation assuming you have all the nessesary parts..it would come up to 2k....maybe 5k for some speed shops..so you would be spend well under 10k for the swap. http://northwestnissans.com/board/attachment.php?s=&postid=147769

As far as the VG30DE (+1990) being converted to turbo...its possible...but extremly stupid. the cost to convert the N/A VG30 to TT would be the same as buying a grade ++A quality VG30DETT and still have money left over for modifications. If turboing a N/A was that simple money wise, my entire garage would be filled with turbochargers.

humm..... i like it i like it i want a rb26 so bad cuz my friend and i are just gonna make it a total sleeper.. he he...

well...u said assuming i had all the nesecarry parts....i dont have NE parts...that 15g's was my estimate including buying the rb26dett w/ tranny.

i dont have either...but i started looking more into the 280z as a possibility for the rb26...well, we'll see when i get the money to do all this.

wingsofwar i want to put in the rb26 and i noticed you had pictures of a z with one. where did you get those pictures. I would like to talk to who ever did that swap. so i can get all the parts to do this swap. thanx

I'm wanting to do this same swap myself , since I now own a 1st gen 300Z (1985). Full front clips of R33 Skylines can be had for $4500 or so , this includes engine , ECU , wiring harness , tranny etc. Of course , this is the AWD tranny , but it can still be traded or sold for an RB25 tranny , which bolts right up to the RB26 anyway. Then , of course , there is the custom driveshaft that will be required , and your choice of differentials. I may stick with a modified R200 , just modding the stock diff that's currently in my car. I've considered an RB25 swap , but I just think an RB26 will better satisfy the power lust I have. Plus , it's a popular engine , and has a huge aftermarket following.

I can direct you to someone that does the RB26DETT swap, although he doesnt speak very good english. He knows what hes doing, I also have a few videos of his Rb26 powered Z31 doing some crazy things...i believe he topped out at 240kmph..if your interested message me...if i dont reply fast enough..then just wait till i do...

WingsOfWar The rims on that black Z what company made those.

yea im intrested wingsofwar. that would be great if you could direct me to that guy. i would also like the video too. thanks

I saw a Rb25dett into a 240sx. There is two SKYLINE RB26DETT ENGINE ON SALE FOR 5,000 DOLLARS It needs a custom parts like intercooler pipe and a back wheel drive from a 300zx and find some one does custom drive shaft and if you want twin torbos you need to find a way to make it right hand drive like the japanese sliva another know here as 240sx (you can use the some of the parts from a 300zx) So the twin torbos won't be in the way of the steering. It would cost you about under 15G for the installion for car and parts only to see it stock. But you have to look for someone with that knowledge.

OK, I don't want to rain on your parade, but think about it this way. You are gonna spend at least 5,000 on just getting an Rb26. Why? I know it's a beast of an engine, but a VG30 is extremely bullet proof and could make tons of power if you invested half that amount on it. By the time you mess around with everything spend tons of money getting it to run and fit you will have a stock RB motor that will make around 277 horses (at the crank).

Instead, get a VG30et or TT (which does have more displacement than all RB series motors except the RB30) spend money on a larger turbo (2 in the case of a Z32), fuel system, intercooler, internals (if you want: forged pistons, rods, etc.) and then see where that puts ya. I can guarantee it will be more that 277 horsepower. And you could pretty easily do all that for less than $5,000. If you really wanted to build a motor get a VG33e from a pathy and turbo that. I've seen the VG33e in a Z31 turboed and everything makin 450 rwhp and over 500 ft-lbs or torque.

If you really want unique and insist on the RB series then check out australia and get your self an RB30 and then get the head from a RB25 for it. I'm pretty sure that would be cheaper than a RB26 anyways, since those seem to be the outrageously priced for some reason.

The Rb30 is alot taller then the Rb25/26. That 450/500 isn't an everyday thing. Ken is the first to make it to that much hp/tq with no nitrous. i've been collecting information about this swap myself for some time now. I've been getting lots of reasons why this swap can't/shouldn't be done. Most of which are like the one above. The only real one I've heard is that steering coloumn gets hit by the block,which is now out the window thanks to the black z31. Does the swap cost money? Yes,but if you really want to do it,it's worth it. The Vg30et,by the way the only straight drop in motor,caps off at about 500hp. The vg30dett cost just as much as the rb engine to get into a Z31,so its another cost vs gain thing.

I know the only straight drop in for a Z31 is a VG30et, I was only referencing the Dett because someone in an earlier post mentioned something about putting the RB in a Z32, which wouldn't be worth the effort.

I know that those hp numbers aren't an everyday thing, but they are pretty attainable if you had 5,000 to dump into the engine.

All in all, if you got the money and really want an RB engine go for it. I would do it too if I could afford it. I just figure it's easier and cheaper to modify the VG30et for now. The other thing that really sucks is that there is not any USDM RB motors so I don't know if any part of the engine was used in the US. So it would make just general parts a bitch to get if they break...just something else to think about if you are considering the swap.

Actually,the rb26dett shares some parts with the vg30de. I don't remember the exact list,so I'm not going to try and list them,but it does share a number of parts.

daymn this is an old ass thread. why bring it up now? Well i dont know about you guys..but here in japan. We do engine swaps for a reason, class and application. Depending on how you want to drive, and what response you want, we tune cars for personal prefrence. Each engine has different characteristics that affect the way a car moves. In such a case, the RB26DETT and VG30DETT can be priced almost the same. Displacement is larger on the VG, and they produce the same amount of power. Yet they both perform differently from one another, The Rb block is more popular because its lighter, more durable, and revs higher. Remember its all application..how do you want to drive? You probably wont understand until you get the experiance because you need to compaire performance. Even though i said all this, most of it wont apply to you US Market racers, because drag racing is more popular here than circuit racing like in japan.

I'm looking for a way to keep the twin turbo set-up on the rb26dett. I'll keep everyone informed of what I find out.

McKinney Motorsports know has a set of modified mounts in production for the Z31. They said they should have a set finished by May. Hopefully,they will have one for sale not long after that.

Just for the record i have seen a 240sx with a Rb26 as well as a 300zx with 1. I'm personally thinking of dropping some serious coin on a RB26 into a 510.

Also the RB26 produces a lot more power then the Vg30

Also the RB26 produces a lot more power then the Vg30

Way to demonstrate the meaning of ambiguity. That statement means nothing. Just because you say it does it makes it so right. I have seen drag VG30s making over 1000hp and there are RB26s making over 1000hp (so they both make the same horsepower I guess). They are both capable of high HP depending on setup, tuning, the amount of money put into them, etc. In stock form the RB26dett makes 277 hp at the crank and a stock vg30dett makes 300 hp at the crank so in that case the vg30 makes more (all other vg30s in stock trim make less than the rb26dett [well i think the vg30det actually makes 280hp, but whatever thats a JDM vg]).

So what do you mean by [the RB26 makes a "LOT" more power than the VG30]? Please be specific and give examples. If you were referring to just the vg30e or vg30et than state that please. Don't blanket all the vg30 motors into one group, if that's not what you were intending to do.

THe RB26 makes more power then 277 at crank it is upwards of 300 at wheels.

OK, and why would I believe you? Once again you cite nothing, you just say something so it must be true.

There you go I cited a source. Do you believe Road and Track or no? If you have some actual contradicting info please post it I would love to read it. Keep in mind this is stock, which is what I stated in my last post as well.

turbozx is 120% correct on this one, first off the only reason people think the SKYLINE is so fast is it's obviously AWD, and you can easily put a single turbo setup on it thus making huge power with a t88 or shit like that, do not underestamate the VG30DETT

Both are very capable engines. I'm doing the RB engine because its easier to fit into a Z31 then the VG30dett.
