this is very useful fact for me but im a complete car newbie who wants to learn more =P. Anyways would it be possible to just install a turbo kit under a STOCK 97+ honda prelude without lowering that compression you mention and work well with it? Also why do i need a air fuel gauge if i want to add a turbokit? I wonder the most is if i have a stocked prelude can i just install the turbokit and everything will be fine... thanks for the help

Well, it would require some VERY expertise tuning to not have to change the compression, also running a low amount of boost might help. You don't really need an air/fuel ratio gauge unless you plan on using a boost controller to change your boost.

So yes, you can just buy a kit and have it installed, just hope that who installs it does a good job and tunes it well or you risk cracking that motor. Also don't plan on running more without changing your internals.

and if i were to install the turbo kit myself? i would like to do everything myself thats the fun part of playing with your car

or if i get it professional installed could i not replace the internals and have it working together properly and adding wears and tears

Well, I would definitely suggest that you take the car to a professional to install the turbo. It is one of the hardest modifications you can plan to do to your car. It is not a simple bolt on like a supercharger. You don't need to replace the internals, but if you want to it will be spendy, and you mind as well have the compression lowered if you are going to have the internals replaced. At least take it down to 9:1. Just my opinion though.

I saw a Mazda RX-7 that did a 5.2 @ 293 at our local track in Sacramento, California. And as we know, the RX-7's rotary engine is 1.3L, only car with lower displacement is like a 75 civic that is a 1.2L.

In most cases you are right, but there is the race occurence that a bad ass low displacement car will pop up.

As for this statement, Self said what I wanted to say, but there is something more. You can't compare displacement in a rotary engine to a combustion engine. A 1.3L rotary is not equal to a 1.3L combustion engine. You are comparing apples and oranges.
