so last few days ive been thinking about what else that i can do to my 7 to get my speed/ power. I've thought about turbo and all but honesty i really dont want to do that, i want to keep it semi stock. also I have an automatic. and dont want to change it to manual.. what all can i do to get more power? ohh yeah i already have done the rats nest removel, emissions,and tb mod, header, and removed cats alll but the main cat. guys please help me out else can i do? ( i have a 1990 rx-7 vert)

thanks april

 

well, the 1990-1991 automatic transmission vert was the slowest RX-7 ever made, so to get more speed and power, the first things I would be looking at (in a non emissions state- TX has no emissions testing right???) would be a true dual exhaust, then after that you are looking at porting the motor, and port matching or port and polish the intake.

After that its either motor replacement (perhaps a cosmo 13BRE swap with auto tranny if you must keep an auto tranny) or get rid of the auto tranny or go with a wet Nitrous system for short burst extra power or a custom turbo or supercharger setup.

you can do other little minor things like a cone air filter and cool air box for the intake and a CDI and Iridium spark plug set up, and good synthetics in the rear end and tranny (redline makes a pretty cool synthetic auto tranny fluid repalcement) but the performance gains are fairly minimal at that level.

 

ohh yeah by the way texas does have emissions testing.. what is that? CDI and Iridium spark plug set up, ???

 

capacitive discharge ignition, runs a much bigger/hotter spark plug spark. it will help a little with both power and fuel economy. examples are MSD 6A or Mallory hyfire etc.

Iridium plugs though? I duno...at the rate the rx7 + the CDI eat plugs that seems rather expensive.

 

actually the Iridiums last about 5-10 times longer than platiums

 

oktey i am still lost ... (im kinda new at all of this) MSD 6A or Mallory hyfire etc. ??? what?

 

ask the belching and burping guy laying on the couch..he'll explain everything to u....

 

lol....

 

Remember that the gains from a CDI system, are very very minimal, and probably not cost effective until you start getting into the street port range or Nitrous range of engine modifications
