Hello all,
I'm new here and had a couple questions (kinda). First off, I had come here before and there was an excellent thread that listed a bunch of online dealers of RX-7 parts and engines and if people had had good or bad experiences with them. I've found some of them in the vendors forum, but I can't find them all. If anyone has that thread it would be really helpful, I can't seem to find it through the search options. Secondly, me and a friend of mine (a fellow RX-7 owner) have talked about what to do turbo/supercharger wise with my car. Obviously it's a 1st gen, but what would be the advantages of each option with my car? It's an '82 with the 12a engine, man. transmission and only 61k original miles on it. So far nothing else has been modified and the turbo/supercharger is something that wouldn't come til after a series of other mods. Thanks for the help guys, I really appreciate it.

the second question is more of a personal preference. I would much rather have a supercharger than a turbo cause of no lag. then again, i never met a fellow rotorhead that didnt rev his engine a few times...

 

Thanks for the thread, that's exactly what I was looking for.

 

If you want to bolt something onto your existing engine then a supercharger is probably easier since you can attach some carb to it and get good predictable behavior, it's harder to tune a carb with a turbo. There are no kits any more for either turbo or supercharger, so you are building your own no matter what you do.

Really the easiest though is to swap in a turbo II engine from a 2nd gen. You can use mostly factory parts this way and sometimes even pass emissions if that is required for you. People ask about this *all* the time.

 

if you are looking for big power, I would stay away from the supercharger. I have seen S/C rotarys at dynos and they never really lived up to the hype. 2 seperate cars are used as a sample. In respect annomosity will be kept. Now as a novelty or for a daily driven car I would not write the S/C off. The combined raspy rotary sound combined with the whining howl of a S/C... creates a sensation that you comand saans army under your hood. Just don't expect to win every battle.

 

There are no kits for a bolt on Supercharger?
Gosh, what is this?

If you go turbo or supercharger you would need to start with a Fresh rebuild.

 

Thanks for the feedback. This is pretty much what I was looking for, just enough info to grasp what the differences are.

 

That is for a 2nd gen, he has an '82.

 

how about this. look at it like this man. how much money dont u want 2 spend. then after that then u will know which one
