**************PAy Attention, This thread is about the old Boxy Colt Vistas, 1986-1991, Not the newr rounded versions!******************************************************

does anybody know how strong the 1G vista awd rear end is? It is a possible candidate for my Hyundai excel which uses this type of rear suspension without struts.

Does anyone have a useful response! Is there anyone who has done a swap with one of these?

I have never seen anyone do a swap with one of these rear ends. In regards to strength I think it is as strong as a 1G rear end or maybe just a little bit less. Nothing is essentially different from a 1G rear end; the differential housing is cast iron, the differential itself is iron and steel, the CVs are probably the equivalent of a 1G 3 bolt set-up but they could also be thicker than the 3 bolt CVs.

I would not hessitate to use a Vista rear end on your car if it will fit better with the design of your chassis. Unless you are seriously looking to make 500whp then strength of the drivetrain is not really a concern.

Thats what I was thinking, It doesn't look too beefy but doesn't look too weak either. I will try to snap some photos this week and also some photos of my undercarriage.
I almost forgot, does anybody know what Gearing these rear ends use? Are they compatible with the 5spd 1G awd tranny, Thanks.

And my original question was if anyone has put a 4G63 into one of these vans.

Thanks

Moderators, can you please move this thread to AWD Tech? I want to start adding pictures I took.

I was able to get a good look at this rear end/subframe today.

The car is an AWD 5-speed 1991 Colt Vista wagon. The rear looks similar to the setup in my hyundai excel, hence my interest in starting this thread. I was able to find a part number on the pumpkin today MB290516 can anyone tell me if this is compatible with an AWD manual DSM Tranny?

Like my car, the Vista does not use a rear macphearson strut. And it looks like the rear of the vista is a torsion type with no coil spring.

Heres the pics.

What's the rearend's gear ratio?

I have no Idea, I was hoping somebody with this knowledge would reply with the answers.

I have OE FSMs for the Colt Vistas at my garage. I will find one and post up the ratio as soon as I can. The manual 1G and GVR4 ratios is America are all 3.545 or simply 3.55. I am unsure as to the automatic but that is not necessary as you want to use the 5 speed AWD box. If your are able to get the transmission identification numbers off the transmission in that Vista I can tell you what final drive ratio it uses. The rear differential may have an indentifying tag on it also.

Every dsm diff I have seen has it written on the back of it

Most of them do. Sometimes the tags fall off or are obliterated by dirt and grime....

Ok, I will try to get that information posted soon.

Hey here is an small bit of text from http://www.lancerproject.ca (converting a 93-96 CSM to awd)
Has a bit of info about the expo diff. (note i did not strip out some of the info so you'll have to sift through it)

"The EVO3 trailing arms themselves provide the same suspension geometry as the original parts, but have a bearing carrier for the rear axles. The same bearing used in the 93-95 Expo rear trailing arms is used in the EVO3. It also turns out that the 93-95 Expo AWD (automatic or manual) have compatible axles. The 3.545 manual transmission diff is the one to use, or else use the 3.545 limited slip diff from the Talon / Eclipse. You will have to be a bit creative in mounting it correctly.

One of the major differences between the EVO3 and the Talon AWD diff is that EVO has a 3 bolt flange on the diff end, while the Talon has a different 3 bolt (1G) or either 4 bolt (later 1G, 2G) flange on the trailing arm stub axle. If the Talon LSD is used, the Expo flange stubs that fit into the diff are used.

So where do you get EVO3 trailing arms? The EVO3 was not sold in North America, and EVO4 parts are both expensive and don't really fit properly. I located my set of EVO3 trailing arms in the UK and shipped them over to Canada. The likely more expensive alternative is to engage a machine shop to modify the existing trailing arms. Not impossible, but would be in the order of $400 per side.

The EVO3 has 4x4.50" hubs that are different to the AWD Expo rear hubs, in that the hub flange is round, meaning they can be redrilled to 5x4.50". Because of their approximately rectangular design, Expo hubs can't be redrilled to 5x4.50". Talon / Eclipse front hubs will do the job, but require some minor machining to the oil seal area so that the rotor mount plane is in the same position. If this is not done, the hub flange plane is about 5 mm further out than standard, which will cause tire clearance problems on the wheel arch."


Hopefully some of this info is usefull to you.

Thanks for your help, however this thread is about using the US 1988-1991 Colt Vista AWD rear end. Not Expo. As I stated above Im hoping this Vista rear end may fit into my 1991 Hyundai excel, which us very similar to Mirage c10 Chassis.
