Since the 83 is old enough, I no longer need to emissions test it. Since i am under the hood anyway right now, what can I get rid of under the hood that will either simplify or give me a performance boost?

 

Leave the rat's nest alone. Get rid of the hot air riser flap and the plastic air horn on the air cleaner...dyno proven 2 HP right there, if I remember right. K&N filter all fresh and red is also a dyno-proven 5 HP change.

That's it for the easy stuff beyond optimizing the ignition system.

Leave the rat's nest alone. All the lines about "running perfect, removed rat's nest and I know I did it right but now it can't even idle, help!"...dang those threads get old.

dont no much on fbs. but i no u dont need a/c, cat converter, air pump(unless its used to open 5th and 6th ports), also buying an elecrtric fan is a plus and adds lots of room. other than that idk....like i said i own a fc.(no knowledge of the fb)

 

The real gains will be with exhaust and a nice carb. But they go together. If you just add a carb, then you won't see any gains until you free up the exhaust flow. Pretty much anything that is not needed under the hood can be removed, weight reduction = hp increase.

Check out this thread from when I stripped and cleaned my engine bay: https://www.rx7club.com/showthread.p...highlight=pics

Besides weight I figure its just that much less to have to clean and work around...

 

Yes, and if it ain't there, then it can't cause you problems down the road. My engine bay is cleaned of 95% of everything that doesn't absolutely have to be there to make the car run. As a result, it is highly reliable. I probably pulled well over 100 Lbs out from under the hood. That cast iron exhaust manifold weighs a ton all by itself!

 

I am told that the Rats nest needs to remain until I convert to manual transmission.
