tiger engines came in buulk like 5~7 years back in Pakistan and many made there way to Deluxe swaps but nowadays scrap yards are all exhusted, you may find any on resale on olx.. or fetch it from some one sho is not using it any more..
but over the time there are many more better engine which soured up in experiments which can be even better choice then tiger.. like for instance some thing like this:
Tekken 250 engine almost bolt to bolt with minor tweaks, 6 speed, almost double the horse power, vibration less, OHC and all the good bells and whistles... this is the cheapest in brand new conversion... rest all other cheaper solutions are from scrap yards offcourse... and rest of the new engine swaps are expensive then this one..
