Exclamation 20B engine swap

hi! I have an 87 RX7 GXL 13B turbo and i want to swap the engine for a 20B 3 engine.

I've heard that theres a lot of work invloved, and my question is, what kind of work? I've read stories where people had to change the fuel system and the ECU.

Baically, i want to know all about installing a 20B engine into a 2nd gen. RX7. I need information on what to change and what else i need to buy, etc.

I really appreciate the help. thanks.

you need everything. the motor mounts are different,
you need and aftermarket ecu, a bigger fuel pump, radiator, turbo, custom exhuast. you also have to gut the t2 hood scoop or make your own hood. the ps and ac wont fit anymore. but its going to be a monster when its running
