The issue is this piston type comes stock on 5AFE and 7AFE but our pathan brothers change these to weaker rottery type denso ones they are cheap and these aka 5 piston ones sell for good money.
A lot of other things also get changed like this. In some engines I saw 4 2 1 headers coming stock they were changed and will be sold later at a better price they call it sports wala exhaust :p.
They will open gears and see if the pressure plate/clutch plate is in good condition tht will be replaced with a weaker one this one will be sold later at a good price. Inner axles come stock with engine they will also be removed and local ones will be installed, Iridium plugs will be removed, Good Looking Denso air filter will be replaced with desi, Original engine foundation which comes fitted with engine will be removed and desi rubber foundation will be installed and the List goes on :p.
