as much as rotaries are engineering excellence they really do have a reliability issue..there is no denying it..you can go on and on about the issues with swapping 1jz/2jz/ls1 but the fact is every where in the world swaps are common place..even places where your local mazda dealership will service and rebuild your rotary for you..
and rotary tuning is a specialist skill. there are only a handful of rotary tuners in the US and Japan building big $$$ time attack cars to prove their expertise...so its not exactly fair to expect someone to be able to tune their rotary in Pakistan..
finally Baqir is probably one of the most knowledgeable people about doing the correct mechanically sound swap..his current RX7 is extreme!
