I have a 1990 Sentra coupe and i want to make it 4WD, i know that the wheelbase is the same for the 1990 4WD sentra wagon and the coupe, so I was just wondering if the drivetrain is swappable from the wagon to the coupe. So if anyone has done it or heard of it being done please reply

Thanks

gas tank and exhaust/chassis clearance is the major problem here ... otherwise, it should mostly all bolt up "easely"

that might be a sweet set up with a CA18det or something a low budget WRX killer

the main problem with swaping an engine over the 4wd station is getting the same diff ratio on both front and rear... BlownB310 used the ga16i tranny to the ga16de so gear is the same... but still no one ever swapped another 4wd tranny in those (neither getting the 4wd into a coupe yet...)

actually, the hardest part is you have to cut out the rear and weld it into the car...they aren't bolted like toyota or subie.

its been done though...sr20det awd n13 pulsar. if you use a CA engine then you can use the GA16 tranny and drivetrain from the 4wd sentra wagon. if you don't use a CA engine then you're shit on your own to figure out tranny and gear ratios. I do know though that you can configure a subie rear diff into the nissan rear so if you could find the right subie ratio for whatever front diff is. Possibilities are there...basically only GA or CA engines engines though, but i believe aussies had E series awd in the n12 but don't qoute me on that. And if you could get ahold of GTI-R tranny a SR awd.

I would rather have an SR20 over the GA or CA engines. Can the drivetrain from the 4wd sentra be used with the GTi-R tranny or anything else besides the GA tranny. sorry i need all the information i can get for attempting this project. and your positive the 4WD sentra rear would have to be cut out and welded in? what other problems do you think i'll face with this project??

I was thinking of something like this for the engine and tranny set up. Would this be a good choice?

Well you can get bbdet rear or a pulsar AWD set up.But it's going to be an all cut and fab project. Fairly a unopened can of worms.. it could get ugly quick if you don't have all you ducks in a row.

you can remove the gas tank for the rear diff. and the
the rear stut towers should bolt? it's all basiclly the same.
just need room for the AWD tranfer and drive line. not to forget the complex inner workings of the sr swap in the b12/n13 on a PITA scale of 1-10 this would be an 8.

my two cents

This is funny, i comes up every few months. Trust me, you don't know half the work it is going to take to accomplish this. I have a 90 sentra wagon rear in my KN13 Pulsar chassis. The rear diff is the same as the GTi-R SR20DET trans I used. It was actually pretty simple on the front to get the GTi-R axles, hubs, trans and all that installed in the pulsar. 3 custom motor mounts and a custom dog bone mount up front did that. The rear is completely weld in. Many of the suspension points and stuff on the AWD sentra wagon are part of the chassis and not bolted on. The fuel cell will have to go in the hatch with a custom unit, not other way to do that. Also, you won't be able to slam the car if you want exhaust, I have a custom side exit on my car due to lack of exhaust channel. OR, you can do a ton of body work and widen the center channel of the car.

I was planning on dropping the gas tank and putting in a fuel cell, i was also planing on the exhaust being something like yours and dumping out on the side of the car and not going all the way back.

CoachFlip, are you saying that the 90 sentra wagon rear diff. would work with a GTI-R trans? Sorry i need all the info i can get before starting anything with this type of project.

The 4WD B12 uses a 3.70 rear diff. If the GTiR used the same 3.70 rear diff ratio then you'll have a match. Someone told me they did, but I would double check that with another source too. Sentra-90, is the desire to for this project still alive?

Although they are listed in the Nissan manual, I've never seen a '90 4WD wagon. I've owned an '87. '88, and currently and '89. If yours is a '90, tell us the story of how you found it and where bought it. :)
