eagle talon AWD tsi 91 or 90 ?

[TSI from Hell]

91 imo.

My vote goes to which ever one is cheaper and in better condition. Don't let others steer you away from a 90 just because of a few slight differences. There's nothing you can do with a 91+ that you can't do to a 90. It's true there are some wiring differences and the transmissions have a 22 spline output shaft and t-case as opposed to the 23 spline used in later years but if you're making enough power to break a 22 you'd probably be stressing a 23 pretty good anyway. There are numerous tech posts and how to articles relating to the wiring and part differences. I've swapped some of my stuff to 91+ style with no problems but still use many of the 90 parts as well. The biggest problem I've had with the 90 is finding replacement ecu's. They are getting scarce since they were only used that one year and when you do find them they either don't work or cost too much.

How is the 90 transmission weaker?
Is there any evidence to back that up?
My 90 Tsi, has a 5 speed with 130,000 miles and none of the gears grind.

I'm hearing a lot about the '90 transmission being weaker then the '91 and up. As far as I know they all have the same transmission. If someone else has a part number the '90 transmission showing that it is different from the rest of the 1gs post it so we can clear this up. As far as I know all 1gs ('90-'91) came with the following transmissions:

1G 2.0 turbo FWD manual transmission = F5M33
1G 2.0 turbo FWD automatic transmission = F4A33
1G 2.0 turbo AWD manual transmission = W5M33
1G 2.0 turbo AWD automatic transmission = W4A33

If anyone has a different part number for the 1990, post it.

They are different, and weaker.

First off that is for 89's 90's and early 91's, so even if you got a '91 you could still have the same gears as the '89's and '90's. Also it doesn't say that they are weaker, just that they require modification to upgrade to EVO gears. They may very well be weaker, I don't know. I'm just saying, show me proof. Also the actual transmision is the same, correct? They just used 3 different sets of gears over the course of the 1g DSM's (1990-1994).

 

[zeekster777]

This is all very good info, I want to say thanks. I am going to keep my 1990 ether way. it just looks better and drives a lot smother to me.

My vote goes to the 91

From my personal experience with my 90 I can tell you that the 90 - early 91 cars came with a 22 spline output shaft on the trans and came with a 22 spline transfer case. There are also some differences with the internals and case parts of the 90's but I can't really elaborate on what they are since it's been 8 years since I tore mine apart. I swapped mine over to a late 91-92? 23 spline trans and t-case but only because the original trans was junk when I bought the car. As for them being weaker I'm not sure. I guess you could compare the difference in strength to the 3 bolt and 4 bolt rear ends. If you're making enough power to break one you'll be stressing the other close to it's limits. Neither trans was really designed to take the abuse we put on them but later units do seem to hold up better.

1990's have 22 spline output shafts, mated to a transfercase with an aluminum housing. This makes them weaker than the later years 23 spline. (which had steel tcase housings)
I was initially replying to your comment about all transmissions being the same, they are not.
Whether OP's 91' Tsi is early enough to still have the 22 spline output shaft isn't what I'm trying to get to the bottom of.

The part number of my original 90' transmission reads:
Kw5m332npzs
The part number on the later dsm transmission I have in my Galant reads:
Kw5m332npxv

OK, that's what I wanted to see. Thanks! So these are all AWD transmissions being discussed and I know that's what the OP was asking about but is there also a difference between the 1g FWD transmissions?

 

[90awd4g63]

I have a '90 and after 6 years I finally had to pull the engine. The only other problem during that time was a faulty ECU; it was Hell finding another 90 Eprom.
Deciding to keep the car after my first deployment, I should've COMPLETELY stripped my little brothers 93 because know I have a bunch of parts I can't use without a wiring harness.

 

[zeekster777]

So it done... I just sold my 1991 GSX, im going to spend all my time on the 1990 tsi... I got 2500$ for the gsx

 

[NeMiZiS]

Good luck with the Talon.
I wish I had 2500 to spend on mine.

 

[DSM_IKE]

^^ same here ^^

 

[zeekster777]

As you all know 2500$ doesn't buy much haha.

 

[zeekster777]

ok sooo i just sold the tsi 2500$. kinda sad but i just picked this car up 2500$ click on the link and tell me what you think
1991 Mitsubishi Eclipse GS-T

So you sold your 91 to buy another 91? And you should post some more detailed pics of the new car, but looks nice from the add.

 

[white92talontsi]

Some misinformation in this thread concerning the tcase.
Not all 22 spline tcases are all aluminum.
I have a 22 spline that has a cast front.

Also my trans is an all original 90 and it shifts like butter. And I nlts it all the time.

Now I will admit the 90 is the bastard of the 1gs. The wiring stinks. Most of that can be solved though.

Wow I just read that guys ad. Just reading it was a giant red flag to me.

Ya there are things in there that made me think twice of it too. Hope you inspected that car really well before you bought it.

 

[zeekster777]

ya his dad posted it for him, but the car is really clean,
it has 2g ported exhaust man

RRE dumptube
3" turbo back exhaust

Indeed there are:
F5M33-2-SPZS ...... 1990
F5M33-2-SPZV ...... 1991-1992
F5M33-2-SPQV ...... 1993-1994

And 2.0L non-turbo:
F5M22-2-VPZS ...... 1990
F5M22-2-VPZV ...... 1991-1994

And 1.8L:
F5M22-1-VPKS ...... 1990
F5M22-1-VPKV ...... 1991-1994

There was also this thread not long ago that had a link to numerous different all wheel drive transmissions; I thought it was interesting: http://www.dsmtuners.com/forums/newbie-forum/385260-there-more-than-one-gsx-transmission.html
