mate getting around the immobolisher is easy , just get are ecu from the us,make sure u get 00, 01 model as it has are higher rpm(8400) problem solved, wiring shouldn,t be that hard, since the echo has vvti, so it will be missing the wires for the all important lift, so probably end up using the echo harness, but im finding it hard to believe u got are 2zz with gearbox for 2500, when i was looking for mine, u couldn't touch it under 4k just for engine, and who is doing the install for 4k(got are name of the shop and number),1 week yeah right,i bet money on it, just waiting for custom stuff to come will pass that. anyway gl
