i have done the 2jz swap, i personally got all the stuff from tech2, fitment is nice, easy swap, however tech2 seems to be very unorganized, it took me about 2-3 months to get everything i ordered from them (and everything was instock)...and there was alot of "fabbing" required to make stuff fit, which pisses me off after spending 1500 bucks for a "bolt in" kit
however...pics
and for further instructions, i would recommend doing this all with a car lift, because putting the motor in from the top is a PITA...from the bottom is premo.
