Vitz 1KR-FE Conversion to 2SZ-FE

Hi,
I am going to convert my Vitz 1000cc to 1300cc with a 2SZ-FE Engine. I have bought the engine from Lahore for 82000Rs and getting it fixed in my car.
Now there are two questions arise in my mind
1. Is the price of the Engine good enough?
2. There must be some changes exhaust system of the 1000cc and 1300cc. Most of the mechanics and engine dealers ive met are saying that theres no need to change the exhaust line and silencers as they are perfectly compatible with 2SZ-FE whereas I believe that there has to be some difference and by not doing so I will be compromising the quality of performance and engine life. Can anybody please advise if the exhaust line and silencers should be replaced and any place from where I can get it from as I was unable to find the exhaust line from Bilal Ganj.
Also if anybody can share their experiences of the conversion in terms of performance, mileage and comfort and any issues they might have encountered who has done this in the past.
Thank you

The exhausts of 1.0 and 1.3 are not the same. This one being narrow will give more back pressure and not allow free flow of exhaust gases. This will restrict your engine performance and also affect your fuel economy.
You have to try your luck in finding a genuine exhaust from engine to the tail pipe because otherwise even if you get a larger diameter exhaust fabricated locally, you will use local material and mufflers which will never be the same as a Japanese one. Also if the rubber mounts and their brackets are not fixed properly you will get vibration in the car.

An original exhaust system is the best for any car. But sadly in pakistan, we dont give it the attention it deserves.
