RB26 sur le S12

[draconis]

Some pics and info: http://www.s12silvia.com I will put more up here later that is not hosted on the site.

super !!!!

[seb.racing]

interesting your web-site, you want me to move the topic in
viewforum.php?f=11 ??

[alundra]

A beast!
Can't wait the details specially because it's LHD.

Hope you all the best

Project daily? racing? drift? drag?

[draconis]

You can move it if you want. I have no problem. I was thinking in the project section since it is a project? :p

[seb.racing]

ok, actually
it can remain in draft

the red is beautiful RB26

[draconis]

You stole the pics. :p I should have done that. Ah well. But I will post up little bits here and there later today or tomorrow about some technical stuff.

[seb.racing]

Yes, I add pictures to mark the spirits when located on the project page

and saw the beauty of RB26, we must share

[draconis]

Well here are some tech. details I can fill in for the lack of pics.

The RB20 setup I had worked for the most part. Due to a hose in the rear of the RB20, it prevented me from pushing the engine further back against the firewall. Well, the RB26 does not have this issue so the motor was able to be pushed back just a bit further. This meant that the subframe needed to be slotted just a bit more to accommodate this change of placement. Then to add to it, the RB20 was situated so that the over the valve cover intake pipe could clear the SE bonnet without having to damage it in any way. Well, it is apparent that the RB26 does not have this type of intake so the passenger side had to be slotted slightly more than the driver's side to sit the engine back in a better place. The other issue that was addressed was the oil pickup under the engine block. Since I ditched the RB26 pan, the only option was to have one custom made or use a RB20/25 oil pan. My plans fell through to get a custom one made up so I went with the Rb20/25 pan. This meant that the oil pickup would interfere with the pan and it could not be bolted straight on. One option many do is cut and weld the oil pan to solve this issue. I refuse to do that so I was able to have an adapter by the shop made up and fitted so that the pickup can remain without issue as well as the pan and plates inside. This though created a 'taller' engine from pan to valve cover. So we ended up playing with GTS, GTR and Nismo mid-mounts. The top-mounts/motor mounts were left basically as is as the lower-mounts/subframe mounts were adapted as stated above.

Then there was the concern about increasing brakes. Since I'm not going for much power at the moment, all I needed to do was increase the front suspension stiffening. I chose to go with S14 tension rod brackets, S13 Kazama tension rods and adapted the s12 control arms by notching out the stock bolt holes just a bit to allow for a better angle and grip for the tension rods. This stiffens up the front end suspension, increases it's steering capabilities and increases brake efficiency. With that increase in the front and the MKII Z32 rear brake swap, I feel I have sufficient braking ability for the time being on how the car is driven coupled with it's power. If I am to obtain more power, then yes, I would do a complete conversion, but for now, the SE front and Z31 rears are actually quite capable. In the pics, you will also see SS brake lines I had installed on both front and back.




Then there is the new radiator. After this setup is finalized, it will be offered to all those who have S12s. These will be rads. custom for S12s and will have correct mounts. Granted, you dont need one like mine but you can ask for your choice of parameters and it can be made up and shipped to you. What I have is a full aluminum rad that is double core/flow. I totally forgot the exact terminology of what it is, so tomorrow I will clarify and edit this. But it will keep the fluids cool and shouldnt have any issues. This setup was used on a S13 with a RB26 before and it worked perfectly so we are adapting that to work with the S12 and fit within the stock setup so that it becomes bolt on for us.

Thanks for sharing!


Perfaps if you need some clearance for stuff, you can borrow this idea for the location for the radiator:

Un projet de furieux, j'adore

sympa l'echangeur les deux sorties du méme coté

c'est un radiateur moteur



remarkable mounting your radiator, I have the same idea to mount my intercooler

effective braking ventilated Z31 is good for S12

regarde les raccord pour mettre les durites, ils sont tout petit

[toytoy]

nickel ce radiateur par contre il oblige à monter un vase d'expansion qui servira en même temp de remplissage !

un peu comme su bmw ...

[Kardey]

génial ,

mais petit détail ..... ne vous laisser pas envahir par l'anglais .... on a fait cette erreur au Quebec , et on est envahit maintenant lol

Tiens j'croyais être le seul québecois ici.. t'est de quel coin?

[draconis]

So it has been several months since I updated. So I figured it was time for a massive update. And yes, by massive I mean, with lots of pics that are technical. Dates with some short descriptions.

Feb. 19th, building of the exhaust:

March 1st

more exhaust





brake line rerouted

[draconis]

Fun stuff intermission.

Yes, collection of number plates. Thanks to Peter for shipping me the two UK plates. I shall use a combination of UK and Aussie plates for photoshoots and at car shows.

Bottom to top: Aussie, Aussie, UK, UK, Cali/US, Washington/US

April 9th

FMIC setup






April 12th




Installed radiator with fan, shroud, and additional bypass.


Fitting the bumper, FMIC, and Rad. It all works within stock confines.

It's a ground/ground missile!

[Yu@34]

its a laugh and to spend the tubes ESC, good work

[seb.racing]

very good job

[Maskym]

Incredible work, it's awsome !!!

[bielle.chaude]

ya du travail ... c est pas un manouche ....

par contre si ca touche pas il a de la chance .. (échappement ) ca passe juste .

et ce qui me dérange (mode jaloux ) .. c est le problème de poid sur l avant de le voiture .. c est dejas un problème sur s13 avec ce type de moteur ..


ya pas a dire c est très beaux ...

[alundra]

T'inquiete c'est du poids utile, on ne cherche pas la beauté de la répartition du 50/50 ici. Avoir du poids à l'avant aide à la motricité même si c'est une propulsion. Sinon on aura du mal à placer l'avant ou le garder droit.

One of several dyno pulls. Using ViPec so there is a bit of tuning to be done in order to fully map out the system.
