The turbo or psi's you run isn't what eat's up the tranny it's the power you put through it, regardless of how you make it.
190-200whp is more than the tranny can handle. So I suggest adding a tranny upgrade ti that list of mods.
Get an oil cooler, and hook it up to cool the tranny. Also, try not to boost in between gears. Yes, I know that's the entire point of boosting an auto ("auto's don't lose boost between shifts"), but the proven fact is that the tranny will not hold the torque and you'll find yourself free revving and bouncing off the rev limiter. If you have the shifttronic, this is a warning. When I was running 8psi, I could mash the throttle in 2nd and actually have it slipping - not shifting, just slipping. Once the rev's shot up, then the tranny would try to shift, but there was too much torque for it to engage. AVOID THIS.
Use the shift mode - and don't floor it ever. Get on the throttle in gear - get off the throttle before you "tap shift" into the next gear.
Also, about this whole AT vs MT thing. Yes, an AT can shift faster, but it's not just about the speed you shift at. It's about the ratios available. The AT does not have the same number of gears. Also, your factory AT's are designed to shift for driveability, not speed.
FWIW - my turbo AT protege was a blast, until I blew the engine. I highly recommend you all consider trading in for a car which is turbocharged from the factory. Mazda's are not the strongest cars and you will find yourself putting alot of money into your car over time. Modding is a disease. I've put over 10k into my WRX and I've had it just about a year. Ask Kooldino, Big Tim, and the other heavy hitters on this forum how much they have put into their cars. Sure, there is a certain pride when you know you've got something performing above spec, but from a monetary standpoint - you'd be better off just saving and buying a faster car in the first place. It's alot safer and economical to buy a fast car and work on the suspension.
In any case - good luck to anyone reading this.

Im thinking about going F/I with my auto 1.6 liter. From researching here on the forums and looking around on the web, Ive kinda got a picture of what I can do with my car. Im going to moderately upgrade the tranny (with torque converter and valve body). Im looking into purchasing a good tranny cooler as well. My boost levels will vary between 6-8 PSI, maybe more depending on how far I go with the upgrading. Shanemazda on here, said that with the upgraded tranny and such (including a FPR, Walbro fuel pump and a voltage clamp) and unleaded gas (maybe 89 or 91?) I could get up to 12 PSI max. Sound about right? Here is my turbo plan for all that are interested
HiBoost 1.6 liter kit w/Schwitzer turbo
Swap out the injectors in the kit for Miata 310 CC injectors
Modded tranny with tranny cooler
Slight engine work (head, manifolds, angle valve job)
Walbro fuel pump, Adjustable FPR and volt clamp
Turbo timer (definately)
Maybe a small shot of Nos (recommended shots?? Wet or dry?)
I was looking at www.slowboyracing.com about some work as well.
How does that sound? Am I missing anything? Opinions?

there is no point upgrading anything beyond an oil cooler for our tranny's.. if you want to keep the stock auto tranny, you'll need to go through and replace alot more parts than that.. for example: some of the internals are even made of plastic.steve_protege said:

So then, exactly how much boost can the stock/slightly modded tranny hold? Probably no more than 10 PSI max? What if piston compression was lowered? And new cams/cam gears were installed?
Personaly, I'd do a manual swap before a turbo.. but if you absolutely must have an ATX, like other's have said, 6-7max for a straight auto, anything higher and it just slipps, dosen't shift, and just kinda sits @ redline until you let off the gas so it can shift. Putting in an oil cooler and upgrade parts for the auto tranny won't make it shift better, it'll just pro-long the time until it needs to be replaced.steve_protege said:

The upgraded parts for the tranny would be just to stregthen it. I would need to find a way to help with the shifting though..... Its not that I don't want to keep my auto, its mainly the fact that the auto is all I know. Thats all I learned to drive on in driver's ed and such. Plus thats all Ive driven since Ive gotten my license. If I had even some know-how about how to drive a stick when I bought my car, then I probably would have driven off the lot with a stick. But anyway..... I also don't intend to drive the car super hard. Its my daily driver so I intend to baby her a bit and occasionally have some "spirited driving". Besides the obvious answer of getting a clutch when I go manual, is there anything available to me to help with shifting if I stay auto?

thx, yeah I aint that much of know it all when it comes to FI, more of an NA guy, but i figured i will go FI in the future (not anytime soon) i just want a car that handles real good and that's somewhat fast. Not big on 1/4 mile, more of a rally/autoX guy, just love the curves
.... i figured I'd have to do some Tranny upgrades, but i dont kno much, so besides switching to better fluid and installin a tranny cooler what else can i do, that's not $$$ (no more than $1000) so i can add it to my long list of mods. thxpeace

Same here, I like road racing and rally racing... boo for drag racing.
I'd say that upgrading the torque converter is the most important mod if you go turbo (regarding the tranny of course)

Where should I hook up the oil lines to get oil to the turbo?

In addition to the upgraded TC, would an upgraded valve body be benefitial? Are there even any good shift kits out on the market for an auto?
