Hey Matt should I beable to use the full GTX suspension, or will I have to hybridize it? I was wondering because I'll have a whole GTX  parts car(The body is too bad to restore) so I was wondering if I should buy a GTX coilover kit.

Not sure. I used front Capri struts and a weird rear strut combo from a Mazda 626 (it works, but barely)

I don't know if the rear struts bolt up. You may have to use the stock Capri upper mounts with the GTX struts.

Quick question, can I use a normal FWD G-type gearset to refresh the gears in the AWD G-Type, or are they incompatible? I was wondering because of the 3-5th swap that Chrispoe was talking about.
Also Matt how will keeping the B6T affect the swap, what things should I avoid doing? Huge thanks guys for being so helpful, it means the world to me!

The 1st-5th  and reverse gears themselves should be interchangeable with all other G series boxes, but Iím not sure if the single cone synchro rings of the early trannys can be upgraded to the double cone synchros found in later trannyís.

Alright I just did a ton of researching on ClubProtege, and other various Ford/Mazda forums.

What I dug up was the Plate Mod by Ferdi, thats no longer being made. I heard on one of them someone has ripped off his design, and are now reselling it. Also while I was searching around I saw of the 3-5th straight cuts Chris was talking about.

In order to build a "strong" G-Series AWD I am thinking of the parts/treatments done bellow:
3-5th Straight Cut Gears
Plate Mod if available
BG GTX G-Series(Due to the front LSD diff/viscous unit)
Cryo-treatment/Shotpeening of gears, shafts, and snychros

Questions:
I was looking around, and saw that the Kia tranny has a larger final drive but it wont fit into the awd case, is there any larger final drive that works in that case?

I believe you are stuck with the AWD ring gear, as it drives the center diff. Im pretty sure it's proprietary to the AWD trans

Hey Matt what size exhaust is on the GTXR2? Im In the preliminary stages of getting my turbo build along, so im trying to figure out what size I will need.  I plan on running a side pipe so I wont have to deal with the axel bends.

There's far more room over the AWD axle than there is on the FWD, and the bends are much simpler. That said, I run a 2.5" exhaust

What metal is the GTX trans made of? I was wondering because I just heard of a treatment called WPC its like shot peening but the grains are way smaller meaning it makes the item being treated alot stronger.  What i was readjng said alot of Evos and WRXs use it on there AWD trans to stop flexing,  but the downside is it doesnt work on aluminium.  Have you guys heard of this being used on the GTX trans to any success?

It is the same as any of the Mazda trannies E, F or G fwd or awd  same stuff. There is a plate mod out there that is machined into the end of the case to help stop the flex under high torque. This causes the primary shaft and the secondary shaft to wander away from each other thus shearing gears..usually 3rd at first then the bits take out the rest. I have seen it take out fifth gear as well. The plate mod stiffens the end of the case where the ends of the shafts live. Only one guy that I know of in the US that was doing these but he has since retired from it. Best to just be nice to them....or have a shed full of good spares waiting for the chopping block. But honestly I have never broke one in all the years..just stay away from clutch dumps.

If I could even find the plate mod would it even fit into the AWD trans?

They were originally made for the fwd BG g series and for the life of me I can't remember if they would work on either BF or BG awd trannies. Honestly I would not worry about it. Just make sure yours is good and be good to it. There is always the All Trac that guys are using from the Celica GT4's. A whole lot of work though.
