2G 2GNT Manual transmission syncro help

[TunerPunk]

ok the syncro is going out in my 5-spd and well double clutching so i dont grind is starting to get old plus i can't down shift without grinding into second period. I have access to the tools and resources of a rebuild or syncro replacement. But I'm looking at a completely new tranny instead if possible. I'm getting conflicted information about what trannys will work on my 2g 420a. so here goes the actual questions.

1. If i go with a rebuild and or syncro replacement is there anything else i should address while I'm inside the tranny?

2. I'm looking for a slightly longer 1st gear ratio tranny with a decent accel/top ratio, what would be a good replacement for those specs or what m/t would I be able to swap?

Can anyone seriously help on this>>>?

There are a few gear ratio modifications you can do to the trans using PT Cruiser/Neon ACR parts vs. the 2G NA trans, as well as upgrading the hub and slider keys to the updated design, modifying the shift detent spring assembly to prevent gear pop out, upgrading the 3rd gear and shift rail to the newer version that has a limiter on the rail, along with using a modified Mad dog shifter that has built-in limiters, or custom machining the shift rails with built in limiters so you cannot over-shift the gears causing hub/slider and gear damage.

On a side note, as for higher capacity, either using a custom gear-set out of better material, or shot-peening and cry o-treating your gear-set is the best choice for increasing torque capacity of the parts. Cost wise, shot-peening and cry o-treatment is what I normally use when gear choices are limited to increase durability and longevity.

Awesome thanks. I had already thought of cryo-treating considering I am going with an high Rpm goal. And i hadn't run into any articles about cross compatibility between the PT cruiser and Neon ACR tranny parts. Do you have any thread links that i can look at?
