I took my car to the track for the first time last month (all I've done power-wise is the basic shark injector) and I really noticed the lack of top end power. I was wondering if the manifold swap can be feasibly done by itself, with nothing but the basic software and adapter kit. Will the A/F ratios be able to be maintained without bigger injectors or other upgrades? I know you obviously recommend such upgrades, but I don't have the money for them right now (maybe later on down the road). I DO have an M50 manifold right now though and can afford the conversion kit. I know I'll lose low-end torque, but is it worth it for the added top end power? How much can I expect to gain in power and lose in torque? Thanks for any advice.
