Torrington Bearing Mod...worth it?

[carvinbassplyr]

I will soon be putting in my new clutch assembly, the one listed in my profile, and I'm just wondering of this mod/upgrade will be worth the money, i.e. make my drive-train more durable/reliable? I've been reading about the mod on here but there are really no details as to how it's done or how much it actually improved anything in the long run. I was also thinking about putting Evo 3rd and 4th gears in as well, will that also be a worth while improvement? I'm trying to kill two birds with one stone since, as previously stated, the trans will be out anyway. I'm trying to make the drive-train/trans less of a "weak point" on this car without turning it into a strict drag car. Any advice, except welding diffs, will be greatly appreciated, thanx!

This forum is proving rather useless...no posts of mine have been answered.

Well, generally for your thread to be utilized to the fullest, you have to wait for the right people to come by and give you insight. Insight that would come from somebody that has done it before.
Now, as far as your original question. Anything that you do to the transmission to help it is more than likely worth it. Especially if you are already into it. It just gives you something less to worry about. Seeing as people double synchro and Evo synchro. Because they knows its a valuable piece of the puzzle. Do it right the first time, there won't have to be a next.

Do you know how to work on trans because its not the easiest thing to do you have to have a press and some other tools. But if you can do I would do anything you can to beef it up!

This mod keeps the gear, and end cap from welding together. Which happens alot. When the shim gets destroyed, the clearances get to large, and the gears in the diff break. I have seen this at stock power levels.

I am not doing the work, it is being done at a shop. I'm just putting in the labor time to take the trans out to save on the repair. I figured since I'm going through the effort to get it out I should do everything I can afford to make the next time the trans has to come out a long time down the road. So the Torrington is a definite go. On top of the Evo 3rd and 4th gears I'm gathering I should double/Evo syncro everything as well? True, false, not completely necessary? Like I said since I'm going through the tedious task of getting the trans out might as well do everything I can while it's out to keep it back in for a long time...any help would be greatly appreciated!

Have you thought about getting a shep trans or team rip. But if you want to go the way your going I would do the double syncros for sure. Do as much as,u can.

Yes I have looked into that...but at the end of the day it was to far out of my price range (basically 1200+dollars) By going this route and getting the parts I'm only gonna end up about $500 out-of-pocket. I'm not trying to 1/4 mile this care, just want it to be a durable dependable DD that will have enough power (aiming for 350 awhp) to be dangerous.

I kind of want to bring this back considering how ignorant I was when I started this. I had just gotten into this car and really knew nothing about DSM's or turbo cars in general at the time, so my apologies and please disregard any ignorant replies/statements before this one . I'm three years into the build of this car (which seems to be a right of passage in this community ) and finally got through the new motor build after the stock 7 bolt did what they do best. After revisiting this thread I realized I never got an answer about the 350awhp goal and my modified stock trans. To save some time...the trans was completely rebuilt with the addition of the full evo 3rd and 4th gear conversion and double synchro'ing the 2nd, 3rd and 4th gears as well as doing the torrington bearing mod. All parts were purchased from Jack's Trans and I will be using a Southbend Stage 3 Endurance clutch. Will my trans be in good shape when I start DD'ing this thing with the added power or do I have need for concern?

Is your goal still around 350 whp?

One of the most problematic points in our DSM transmissions, is the center differential.... It came stock with a two spider cross shaft, and it tends to break at major power levels... I would put in the 4 spider cross shaft...

You can contact Tim Zimmer at TMZ Performance to get some help on that, he helped me alot with my transmission...

At 350whp you should be just fine. The upper torrington bearing mod defiantly helps with reliability. Personally I would shy away from the evo3 3rd and 4th, because they are weaker than stock. They have 1 less tooth than stock, so therefore the diameter is smaller, when used with a dsm intermediate shaft this increases backlash and tip loading of the gears. I know Jack claims they are stronger, but doesn't say why they are. I doubt it is an issue at 350whp however.

Yes, my goal is still 350awhp. I'd really like to have the 4 spider setup. How difficult is it to install? Not a competent trans guy, but with the new motor going in there will "easy" access to the trans so if it's not too bad I could have it done.

I believe the biggest selling point is the gain of double synchros by using the evo gears.

It requires opening up the case again, and you need to know how to shim it out for the best performance, but it isn't anymore difficult than breaking it down to the gear set is. If you haven't worked inside the gear set before though, I would suggest having a shop do it and you tell them how you'd like it shimmed. There is quite a bit of info about it on Jacks Transmissions website, iirc. Another site you can check out to see how involved it is is Dre

I see...well it sounds like I'd have to take the trans to a shop, have them remove the center diff, send it off to Jack's to be machined then have the shop reinstall it...which I may not have time to do unfortunately. Sux...maybe I won't be upping the boost after all.
