Do a 1nzfe conversion, 105bhp out the bag, won't need much to get it to fit as 2 of the mounts are the same and one will need small amount of work, gearbox are low ratio from factory, better on fuel, you'll have Vvti, alloy block so lighter and easy to get 125bhp/125 torque with a free flow zorst and a open filter. Would see 150hp/ton+........ and...... it's not been done yet
