I used 1N turbo for two years in Datsun B310
The performance with turbo was awsome also gave me unbelievable fuel economy
It did 25km in 1 liter diesel
But my turbocharger giveup after every 3,4 months
I used air filter that contains oil (cylinder wala air filter jo lohe ka bna hota h jis m oil dalta h)which is mostly used in suzuki Ravi and Bolan( carry ) because of dusty lower punjab environment
The turbocharger that i used was stock that comes with 1-N . Parts of 1N are easily available from Rawalpindi market
I removed turbo from my engine and now it is still giving me good fuel economy 20-22km in 1 L .
But without turbo car seems under power
