I have a 1984 rx-7 "GS". It has the Racing beat intake manifold with the 4 bbl Holley as well as headers and a high flow cat. It has a electric fan (don't know if that makes a difference on rotary's) And it also has two MSD independent coil packs. Any idea how much hp i should be putting down?

 

The stock ports on the 12A (especially the exhaust ports) will hold you back a lot. Maybe 120HP or so if the carb is tuned properly.

 

The thing is i bought the car on monday, so i'm not quick sure if it has anything bored out or ported. i have a good 200 pages of reciepts i need to go through so if i find anything out i'll post it up.
