That's one wild project!
Waiting for the final decision about the front suspension.

USEF says "Impulsion is the term used to describe the transmission of an eager and energetic, yet controlled propulsive energy generated from the hindquarters into the athletic movement of the horse.". How cool is that? Impulsion build here

so it looks like the whole front axle is moving forward.

Good luck! This will be crazy/cool when it's done!

Are you aware of the need to run ABS wheels speed sensor on all four corners plus the ATESSA control module in order for it to be AWD... otherwise, you'll end up with a very HEAVY rwd setup??

Is so, what rear axle/hub setup are you planning to use?

THAT IS EASY, anyone can camber a skinny as tire till it dosnt rub. Now fitting an 11 with a 315 on stock fender with reasonable camber, that is fitment. And looks, and performs better than both.

Looks like they got a big chunk of it, I don't see any reason why it wouldn't work at this point.

IF they pull it off.... THIS would possibly be the coolest S12 EVER. Hands down.

It will be used system "4wd" or "2wd" without use ABS......

Wow that is a project and a half. Looks promising so far though.

Lol club s12 ftw.....  Only here have Ive been told they look like shit..... SOrry its not bone stock with crown vic rims running the stock vg making 130whp and looks generic like every other one. My car looks dope ive been told this a billion times on local forums....

What I'm saying is the attesa system need to use speed sensors from the 4 wheels in order to activate the FWD portion of the AWD system.... if you open the AWD transmission transfer case, you will find a clutch drum inside that make a couple of chain turn your output shaft going to the front diff.... in normal driving condition, the "clutch drum" is spinning freely, making it basicly a RWD, that is why you can run a GTR on a RWD dyno.... When the ATTESA controle module (which is wired to all four speed sensor) detect rear wheel spinage, it activate the clutch drum in the transfer case and thus, transfer some of the power to the front wheel, with a maximum of 50/50 power between the front and rear axle...the ABS speed sensors are not to use ABS brake, but to use as input data for the ATESSA controle module for it to control an hydrolic pump to lock/unlock the the clutch in the bell inside the transfer case

In other words, if you don't connect an ATTESA controle module to 4 speed sensor, you'll end up with a RWD fitted with a transfer case that will be disconnected from the transmission permenantly, thus making it RWD and if you activate permanently the clutch in the transfer case by jumping the power on the pump, you will turn the system into a 4wd without a center diff, thus making it inefficient on dry pavement/street.... the beauty of the ATESSA system, is that it's not on/off like a 4x4, but it's constantly adjusting power biais between rear and front axle over changing driving condition...

Tom is correct.  It was half the reason why I chose not to go that route.  I am curious as to how this will be dealt with.  Not to mention, I've personally never heard of anyone using the needed ecu mated to an RB20.  If you need help, let me know.  I may be able to answer some questions concerning your project.

fastback_silvia

very cool. this could be the next great s12 to grace our scene.

Nitro

I will help Vovka a bit with the translation
It will be set up to manualy switch from 2wd to 4wd, no fully operational ATTESA system !YET!  Need to make a normally driving car first, then can proceed with the details. It will use manual switch, connected to the hydraulic clutch in the transfer case.
The front suspension is for test-fit only, he is still designing it. I say that the simplest way would be a custom front suspension like the RaceSilvia from Sweden uses.
When there will be updates we will post them here.

Cool... so esentialy this is not an AWD s-12... it's a 4x4 s-12... as for now with this setup!  Could be a really cool rally car, 4 wheel drifting all over the place   Keep us informed...

Ah and for Colin's info, I believe that the Atessa control module is completely independant from the engine's ECU, in other words, it's the same module for the rb25, rb26 and even vq35 (g35x)... oh and their is a 93 skyline AWD for sell with a rb20det up here... I'll go search for the link....

*edit*

Sorry, i thought it was an r33 but it's a 91' r32....
