I have a 1993 toyota extra cab long bed pickup that i plan on keeping till the day i die. I had planned on doing a small block chevy swap, and keeping my stock 5 speed because it is an awesome transmission, but i stumbled upon the 4bts and this website a couple months ago, and I definately no longer want to put a gas guzzler into my truck. I want to put a 4bt in my truck now but know that i will not be able to retain my stock transmission due to the amount of low end torque a 4bt puts out. I definately want to use a manual transmission. This will be a long buildup for me. I will be sourcing the parts as i find them, and as i can afford them. What are some good 4x4 transmissions I can use behind a 4bt, or even ones i could convert into 4x4. Also would a np203/205 doubler t-case hold up to the torque?
