I've got a 2nd gen RX7 and I'm looking for an engine to replace it with. I'm most definately sticking with a rotary (anything else would certainly be blasphamy), but to me, my only real options for a significant hp boost would be one of the following:

a 3rd gen 13B turbo,

a 20G engine (turbo or na whatever),

a RENESIS engine,

or spend a similar amount of money making my current 13B have as much hp as any of those above


Any suggestions as to which would be the best, which would be the cheapest, and where to find said engine.

Much thanks for any help

 

just go a 13bt out of any 2nd gen bolt on a t04 and get some bigger injectors and a new computer. with a good tune you should make decent power . if you want more look into porting !!!

if you have any question just ask
