hahahahahaha uss difference se to Allah mehfooz rakhay :). I will try to mount it as high as possible. The hose is quite long (flexible one). I'll try to get a spare one to alter its length. But first I am looking forward to install the IK20 in corolla 
Here is the feedback for Datsun after drive:
The response has increased. Previously the car was finding hard time going to 4K RPM in 2nd gear. Now it easily goes till 5K RPM (60 km/hr)
As you know its not properly tuned right now so response is expected to increase after full tune up. But so far the results are very good.
