Surprisingly the price's are still the same there are just some minor differences.
Pistons are 0.50 crank bearings are 0.25 and Thrust washer is 0.125.
SGP head gasket was used because of it's thickness as head and block wasn't resurfaced so using the normal thicker gasket would have lowered the compression ratio.
The reason behind changing the engine oil would be sludge formation. SGO being mineral leaves alot of sludge deposits while ZIC X7000 is a semi synthetic so it would do better and also mechanic said you can use till API-SL no newer than that it has the required amount of ZDDP that Suzuki G10 needs.
AC gas was saved.
Regarding the break-in period when i went to workshop mechanic was connecting the wires and engine was started infront of me and it was kept at approx 2-2.5k RPM till the Radiator fan kicked on and off then idle rpm was adjusted air/fuel mixture was adjusted and ignition timing was adjusted.
Then car was taken out for a test ride with mechanic driving while i sat in the passenger seat. On empty road's he accelerated the car in 1st gear and then let in de-accelerate shifted to other gears and did the same.
Then we headed to a straight road where he drove varying the speed between 70-90 km/h and car was handed over to me with a advice don't baby the engine or don't be too harsh on it drive the car moderately.
The differences i felt. Car feels a bit heavy on acceleration but i think it's normal within the break-in period. The engine vibration and engine noise has gone engine is silent and smooth now.
