Woah, seems like G15A is ample enough. It can barely put down the power (maybe that's because I am on 13" rims). Still I'd imagine they are more of a straight line cars. @rozzzzz had a 4efte in his khyber. But haven't really seen any feedback from people regarding how the car drives after these more powerful swaps in Khyber. Mine drives really well with a G15 though.
I've not really gone into the details of what will be required. Khyber was a cheap project for me, I plan to do EK properly. If we do bypass the immobilizer is that bad for the swap?
Bhains ki taang! Is that even driveable? Or maybe lots of money was spent on the suspension setup, but dayum.
