Turbo or supercharger

Superchargers are very reliable on the street but you are limited to the amount of boost you are able to push. Turbochargers has a much higher potential because you can always turn up the boost to much higher levels and as long as you have enough fuel for it, you should be good. In my opinion, I prefer turbo.

I'm sorry but that is completely absurd. The advantage of superchargers is that tuning it is cake since the power is linear.

However on a turbo it's nowhere near as simple as "if you have the fuel, up the boost". Mechanical parts start to go on cars, especially the factory N/A engines that were turbocharged. Secondly, unless you're running a badass turbo, you'll fall out of the efficiency disgustingly if you up the boost to much (like 17psi on a t25 from a redtop). The car will hold it, but you're destroying the turbo.

In essence, yeah.... more power comes from turning the boost knob higher. But those who do that have no idea what they are in for unless you have a good $5k+ in turbo parts, engine management, fuel delivery, etc.

A supercharger is much safer for that matter.
 
When I say turning up the boost I dont mean just turning it up while you are driving on the street. I'm talking about gettin the fuel tuned to run more boost. And I do know that turbos have an efficiency range. I know its not that simple but if you have the right set-up it can have much more potential. Superchargers are great but who is going to be driving a top fuel dragster on the street? or to autocross? or to drift? And like I said, superchargers are very reliable. Turbocharging gets expensive but if you want to get things done right and stay safe, you have to spend the extra money. Otherwise you better have a back-up car. But I apologize for not being clear on my post.
 
The turbo I want is a $900 bucks. :(

But it's a perfect universal turbo for my car, and it's quite sexy on top of that. GT40/T4 - 832 cfm - 61mm inducer - 0.84 aspect ratio on the turbine housing... Big power, efficiency, and remarkable spool time on my car. I can't wait... Now I just have to go sell a kidney with cocaine in it on the black market real quick...
 
^ Journal bearing GT? Wouldn't the 35r be a better choice and it's not much more money either.
 
The GT40/T4 from Cheapturbo.com runs the same compressor housing as the 35R if I'm not mistaken. The only problem is, I don't know of anyone that makes a T3 flange exhaust manifold for a rotary, which is what comes on the GT35R, AKA: big bucks for a custom exhaust manifold. HKS makes a very nice T4 cast manifold. My spool time on the GT40/T4, will be roughly 2500-3750. Not too shabby... Remember, rotaries have three times as many exhaust pulses per cycle than a reciprocating piston motor.
 
I know its no $10 difference, but your transient response should be vastly improved with the BB setup. At the very least you can impress people with the compressor spinning for a minute after you shut off your car. ;)
