where the hell can i find a 13b turbo swap for 89' rx7 in (so cal) for cheap

I hope you know what you're doing cuz a swap is tricky and you didnt read stuff like that off a random forum or something. Look for a rotary specialist shop and ask them about it and see if they can actually pull off the swap with you before you think about obtaining parts for it. Not only that, you should know that the NA RX-7 may not be able to handle the power as well and you might have to change more stuff than you think you do. Theres always google. A quick search yielded me this : http://www.mazdarx7engines.com/ You probably cant get OEM parts and will need upgraded parts from aftermarket manufacturers like a carbon fibre driveshaft and an upgraded ECU. Lastly, consider selling your ride and buying a RX-7 13B-T instead. It will save you money and time, even if you have to tow the car from elsewhere.
