unuseable. If you are looking to get into the throttle and get pinned to the seat at a high RPM/MPH pull then they should serve your purpose. If you are looking for performance (be it a 1/4 mile, a road track, or an occassional street pull), matching the components is essential. Those are mismatched turbos on our 3.0 liter cars. While the peak numbers may be very impressive, the useable part of the power band is fairly narrow. Certainly, it's your car, but there are other suggestions made below that will result in better response, and greater useable area under the power curve. I'm kind of a 1/4 mile guy, and it's intersting that the bigger the turbo the more the MPH, but the ET doesn't increase correlatively. I think the ATP tech was looking to make a sale and not considering the driveability of your set up. I see you have 530bb turbos, those coupled with manifolds, a set of 400+ cams, and some good head work (we all need good head work once in a while) will be a pretty spectacular all around car. Again, your car..your goals. Just my .01$. By the way (I guess this a shameless plug), a set of lower ratio gears will decrease the amount of time that it takes the engine to get into the sweet spot and light up the turbos. Seb is going to try a set on his car this Friday at the drag strip (He has a 670 rwhp sport 700, inconel manifold, 500 cam set up). Good luck in your choice, Mark
