i have a 91 na rx7 with a cosmo 13bre twin turbo engine. i have the stock ecu and wiring harness, and i was wondering if i need a whole new ecu or if a piggyback style ecu like the haltech interceptor would work. im not good with wiring and electrical stuff on cars, so im kinda looking for an easy way to get my engine running. also, is there any way to make the turbos work sequentually in my car? what modifications will i need to do to switch to single turbo? id really like a turbonetics turbo if i go with a single turbo, which one will help get me at least 300whp? sorry, but i dont really know that much about turbos yet so im really confused, but im trying to learn all i can.

stock ecu for what?



you CAN wire up a stock sequential turbo ecu (or power fc) and make the sequentials work, but its a ton of work, lots of heat and a single t04 will make more power
