Hello, newbie here with some questions. I went to the dealership the other day to drive a 6MT and fell in love with it. I've done some research on the aftermarket superchargers, stillen, procharger, Vortec etc. and need some input. How much can the stock internals of the engine and tranny handle? I don't want to go crazy, just want a little something extra, maybe an extra 80hp RWHP. Since the car(in my opinion) has sufficient low end power, I was thinking along the lines of a centrifugal s/c rather than the roots type by Stillen.

For you guys with s/chargers, was a computer recalibration necessary after installing it? Did you have it dyno tuned, have a chip burned or use a laptop?

Sorry for all the questions, just want to get the do's and dont's before I make a decision.

Thanks

 

I have the Vortech and yes I had custom programming of the piggyback ECU done. At the time my kit was installed, there was not G35 program so it was necessary to modify the 350z program to get good, safe gains. However, even now that there's a G35 specific Vortech kit I would recommend paying the money to have the SplitSecond device custom tuned, even though it costs an extra several hundred dollars.

Also, from all the posts I've read, our engines will need internal mods when horsepower exceeds 400. I am not sure if this is at the crank or to the wheels. Hopefully some of the other guys on this site can clarify for you, or you can check some of the recent posts concerning that topic.

 

Thanks guys!! I'm not looking to go over 400 hp but I'd like somewhere around 300-320 rwhp.

Is this possible on a safe tune without sacrificing the engine or tranny? What's more popular, the vortec or the ATI?

 

Vortech is safer. ATI has had many issues recently.

 

This is a great forum, thanks for all the info.

 

If you want in between 300-320 just get a zex wet kit or a good e/a and some pulleys. As far as superchargers, they are made to run on the stock internals so you're fine. Get the vortech, and spend the extra bucks to have it tuned. You're already spending about 6 grand at least, what's the extra 500? Better to ensure saftey then to say bye bye to your car... and then what's left.. "frozen cookies" TEAR!! [img]/w3timages/icons/frown.gif[/img]

The procharger is a great kit. I did one at my shop took me a day to do. I dynoed it with the kit before it was 221whp its also a 6 speed. After kit install did 346.4whp this was with stock headers and exhaust.

 

221 stock on a coupe?
