"atessa" is the name of the awd system not the car. Bluebird, gtir, avenir, Primera awd, and most other nissans from that era with the sr/ca awd uses the atessa system

You can always do the awd conversion and then modify the gearbox to lock it into rwd. Heaps of people do it here as a different drift car (primera/bluebirds)

not only on that era! R33 R44 and R35 comes with ATESSA ETS ELECTRONIC controled obviusly in variable modes that configuration, ATTESA on B13, Gtir, BB, avenir, priemeras are complete mechanical assisted by attesa ecu ABS to sway control and traction problems, ETS are electronic diff silinoids to control traction sway, soft or hard configuration etc etc

Front Engine AWD - The easiest way to do this I believe is to get a narrow-block SR20, and an AWD transmission (with transfer case). The narrow block SR20 engines came in any SR20 car that had AWD as an option. This includes the BlueBird and GTi-R obviously, but maybe the Avenir too?
The transmission on the BlueBird used Altima style mounting I believe, so people go with the GTi-R transmission since it used B13 style mounting.

So once you have the engine and transmission, the driveshaft is your next thing to deal with. I believe a GTi-R driveshaft might work, but you might have to go custom. Then you have the fuel tank to deal with. Again the GTi-R tank might work, but I think most people go with a fuel cell.

You'll need to find a place to run the exhaust since the center tunnel will be filled with drive-shaft now.

At that point the rear suspension, rear diff, and halfshafts are your last concern. The GTi-R stuff basically bolts up I believe, so you're home free. It might take a little bit of fab work out back, but nothing too bad.

Forum member @BusinessMan_24 did this with his B13 (NX2000). There is a thread around here on it.




As for RWD, things get a little more complicated.

Front-Engine RWD - You'll want a RWD SR20 setup, with a RWD SR20 transmission. You have to deal with the driveshaft issue, which probably means custom. Same issue with the fuel tank here as it will get in the way of the driveshaft, so go with the GTi-R fuel tank or a fuel cell. The rear suspension, diff, and halfshafts could be used again from the GTi-R but you might want to think about working in an S-chassis diff into the mix to handle the torque.

The firewall will need a good bit of work to make room for the RWD transmission placement. You will basically have to create a transmission tunnel from scratch. You're then going to likely have a hell of a time figuring out the steering rack. This is probably the biggest issue with the least research done. The RWD engine layout and transmission will need to use the space that your current steering rack occupies. The steering column may need extending or other work depending on where you decide to put the steering rack.

You'll need to find a place to run the exhaust since the center tunnel will be filled with drive-shaft now.

And then of course you'll have to create the engine and transmission mounts for the RWD setup, but that shouldn't be too hard.

Get ready for chassis flex up the wazoo.




Mid-Engine RWD - You could always attempt this style of conversion which will mean putting the FWD engine and transmission basically where the rear seats and fuel tank would be. You'll have to fabricate a support frame for the mounting and convert the suspension style to one that will accept the engine in this configuration including spindles/knuckles that accept halfshafts.

A fuel cell would likely go up front where the engine used to be, and you'll have to run some long radiator hoses, etc.

This style has actually been completed by one of our forum members @OnTheChip but it was in an Integra, not a B13.


GTi-R,blueBird,Primera,B13 AWD,Avenir are same tranny on case, mounts everithing, only a few changes on gear ratio, but any tranny can be used for AWD convertion, rigthnow i have a Bluebird tranny running on my car, i have 5 AWD tranny on Spare and i comprare all tranny and same..

Do you have a write up on this? Or a list of parts needed and pictures?
I'm very interested in this.

Thats half right.

The attessa on the P10, B13, N14 erra is completely mechanical as you mentioned. they are NOT assisted by any ecu... not all awd attesas are ABS ether. (my first awd p10 had no abs) They use the same ecu's as a fwd (no extras for being awd). I have my current p10 awd completely stripped and theres no signs of any extra ecu.

GTi-R,blueBird,Primera,B13 AWD,Avenir are same tranny on case, mounts everithing, only a few changes on gear ratio, but any tranny can be used for AWD convertion, rigthnow i have a Bluebird tranny running on my car, i have 5 AWD tranny on Spare and i comprare all tranny and same..


Half right again, Gtir & bluebird (det) use the same tranny, but the mounts are different however they are interchangeable.

P10, B13, P11 AWD use a different gearbox (smaller 32 series) but again you can swap in the gtir/bluebird box by swaping mounts/axels/selectors (and modifying gtir front gearbox mount) This is what i have done to swap a gtir tranny into my awd p10.

I am lucky to live here to to have factory awd b13, p10, p11, n14 ect easily available.

well , y gtir comes with a g force sensor and that is conected to the abs ecu, when i try to " drift " or " sway " my car ABS do they respective work to prevent sway on the car, i ned to say not all GTi-R comes with that , i think nismo editions or optional, belive me when i said i hate that i disable the complete ABS electrical, ABS ecu are diferent part number from normal ABS B13 or RNN14, sensor was located on the midle of GTi-R
i dont know if P10 or p11 or any other come with but some GTi-R comes with

It's easy as hell. Take all the money your about to spend and time your about to waste not driving your car because it's going to take for ever and go buy a 240sx with a SR20 swap in it. Or go make a car payment on a EVO 9 or 10. Easy deal.
