Yes and no. Probably not but you might get lucky. ;D

The .48 Turbine may hurt you to an extent as someone else stated, however, it's plenty of turbo to get your feet wet with. Run it. If you already have a well maintained turbo, get a decent intercooler and get to work.

when you say it may hurt me to an extent, what are you refering to? is it worth just waiting and getting a .63 housing?

No run the turbo you have and when time and $$$ permits, sell that turbo and get out of the TO4B range all together.

To clarify my answer, the .48 is NOT going to allow you to make peak power, however the turbo is going to help you make a lot more power so run what you have and then when you are ready dump the TO4B. Swapping to a .63 A/R turbine housing will help, but you will still have a TO4B which will limit the amount of power you are producing overall anyways.

Good ----, right here.

I have the opition to get a .82 hotside, will it help or hurt me?
keep in mind all i want is 300whp, I'm just not sure if the .48 will limit the rpm to soon, or if the .82 will lagg to much. i would be happy if the turbo was fully spooled around 35-3800 rpm.
what are you thoughts?

Same discharge flange as your .48?

If so, just get it and then start with the .48. That way if the .48 chokes the chicken you can just swap it out.

Hell, get it anyway, it's a FWD and a little lag is better than blazing hot tire fire.

My thoughts are... Listen to BoostGear.

What he's saying is, you will get to or close to your WHP goal with what you have and you should spool pretty quick. Going to an .82 will create more lag, which you don't want on a daily driver. I'm assuming that's what it is, since it's not built. He's also saying you won't hit your max potential with a .48, but I think you may want to get "used" to 275+HP before you start looking at more. With that power, you will be smoking 'stangs like weed was just legalized ;) If you don't kill yourself or go broke from tickets in 6 months, then start thinking about a built motor and a bigger turbo. Hope that helps.

And a smaller turbo doesn't "limit" your RPM, it just won't flow the amount you need it to for steadily increasing power. You will still be making 275+HP @ 8000 RPM.

what are you talking about^ how do you know when he is going to make power? do you have some sort of badass fortune telling brain dino?
