Hi all,

For anyone that has done or know for this kind of project, I was wondering what would be the most suitable r34 model to use as a base (money/difficulty wise) if you are going for an as close as possible to a gt-r swap.

More specifically, to run a 6 speed rb26 AWD.

Most parts will be swapped anyway but my main concern is, is it worth the cost of a gt-four since it's AWD already just so I don't have to cut and make room for the front diff plus any addional parts I may use for the AWD system? From what I know it uses 4.3 diffs compared to 4.1 that the gt-r uses so that will probably change anyway.

Basically my options are:

- gt-four for the fit ready awd chassis and whatever I can use from the drivetrain

- 25gt which is easier and cheaper to find but I will need the AWD drivetrain and cut/solder for that to fit.

I'm not a engineer so might some stuff sound stupid or I miss a lot of other things so feel free to add any comments.

 

Cheers,

 

 

 

My immediate reaction to these inquiries is always "It's just not viable". But.... I suppose now that values of 34 GTRs are stratospheric, the money (and the effort) spent to "GTR" convert a lesser 34 is going to be nowhere near the value of a GTR.

But, I do have to ask.....what's the point? The RB25Neo is just as capable, if not better than the 26 to make power from. Even if you put all the widebody panels on the car, it still won't be a real GTR. So.... why not just build up a GT-four?

The main thing is to be AWD, I don't want it RWD thus the concern. So even keeping the rb25 it has to be awd one or the other way.

Now about still not making a genuine gtr and not having the same value that is true. However with those prices atm which they can only go higher still would cost probably cost 50% less including body work etc. And for the value, not my main concern atm, def won't have a gtr value but probably could make it's money back if I ever decide to move on

The clever way is what GTSBoy has suggested (as it often is)

A GTFour with a RB25DET Neo drivetrain from a Stagea (i.e AWD) is the smarter way and likely better performing way than putting a RB26 in there instead.

Doing it with a GT is just more work, to the point where asking what base car is kinda irrelevent lol. About the same difficulty as doing it with a 240Z or 350Z or Holden Commodore.

🤔

It could be, but I looked into someone who had AWD converted his Monaro and realised it'd be subframes and god knows what and manual gearboxes grafted to driveshafts and it became 'yeah nah' quickly.

Though its probably possible with a mix of parts.

Curious why the rb25 would perform better than the rb26? Is it because of the block or head? I've seen many swapping to rb30 block and keeping the rb25 head.

My sweet spot would be around 600hp, nothing crazy but plenty of fun for everyday.

Also no one drives a 600hp skyline everyday.

I drive a dc2 typer 400hp all motor every other day even for a small ride. Daily and easy to drive? Definitely not but I prefer joy over comfort atm.

My friend also uses a 650hp evo 10 full interior as a daily and isn't a pain at all even for longer trips except parking spots lol. I guess is just what you prefer.

Blocks dont make power , their only job is to hold together

 

It's the rb25det neo head.

VCT, solid lifters and way cheaper.

 

I have heard the rb25 block is weaker tho no? Same goes for the rb26 with thinner cooling holes? That's why they go rb30

No. The RB330 block is arguably weaker than either, because it is taller. None of the RB blocks are particularly good, but the 30s have a longer section up near the deck with very little reinforcement.

There is little to no difference between a 25 and 26 block. There is absolutely nothing special about the 26 as a block or engine. It was just a mass produced engine.

People go RB30 for one reason and one reason only. Capacity. (Which leads to torque, which leads to power, which leads to everything being better).

Thanks for the insights mate!

    • Haha luckily we don't have emissions, inspections, or any laws against power adders here. They only thing they somewhat keep an eye out for are ridiculously loud exhausts. 
    • Just wanted to pop in an update on my setup. The CD swap has been great, I love the mazworks housing for the overall simplicity. I ended up sealing my trans tunnel with a thin sheet of aluminum reused some of the holes on the trans tunnel, and laid some window sealing EPS foam around the edges. Works great, really quieted things down and sealed up the car.  As for the power comment. Right now I am also running about 650whp. with the way the bell housing is attached to the face of the transmission I have zero doubts it would be fine, mainly because the input shaft and main shaft bearings are seated into the bell housing adapter. This means the load is NOT on the bolts to maintain the power, rather into he casing of the bell housing; Yes the bolts are doing some work there, but with both shafts locked in zero worries.  End of the day, the Mazworks solution is the easiest and safest. no need to take your trans to a shop to get milled perfectly, it fits with minimal clearancing, and you can use all your existing clutch and flywheel.  Driving wise the CD has been great compared to the big box, I'll probably swap my final drive at some point. The serial 9 shifter is gooooood, my only qualm is how tight it is, it takes a fair bit to get use to, 5th and 6th are a bit eh/hard to find at times, but maybe I need re-adjusting, and I think my clutch master is very tired and needs a rebuild. 
    • If you are keen, have a look at my build thread. Car is for sale for the right money or straight swap for a F80 M3 LCI.
    • Welcome mate.  No point in over thinking it, buying any one of those cars you mentioned is not a smart or logical choice with the availability of many "better" (re price to performance) cars available to you.  The heart wants what the heart wants, buy whatever it leads you too.
    • Hey everyone! Im so grateful to be apart of this community and ill do my best to be apart of this. Firstly, i'm not disclosing my real name due to in real life circumstances surrounding my privacy and public image (sorry lol) Secondly, The only thing personal I am willing to share is that I'm from Sydney and a descendant of one of Sydneys largest mortgage firms. I got gifted my first ever car, a 2022 Porsche Cayenne and I love it to death. Ive been driving it for about 5 or 6 months now and honestly Im so grateful for my parents for gifting me this vehicle. However recently I've been working my ass off to afford my second car (which I need help deciding soooooo community help me out please?). Once decided, im planning to try modify it myself. Recent I've been thinking about getting a Skyline, particularly a 25GT or GT-V, yes I know overrated as hell, but I'm also considering a Chaser which I recently came to love. However my dream is to one day own a 180SX (So hard to find clean versions and im not really into importing).  Lastly before I send this off, I want to apologize if I sound tacky or pretentious. I try not to and want to genuinely learn from everyone and anyone. (Im no expert in this area) Thanks for reading!
