I was just wondering if anyone has used this turbo kit in the past or still do. I also want to know how good it is and w/ this manifold.

click on turbo kits then on ATP "Stealth" Factory manifold kits


click on headers then on the BORLA STEEL CERAMIC COATED HEADER.

ATP's are shit, they work but they had to redesign the hotside which not only increases lag, it decreases topend. It generlly adds about 1000RPM's of lag and they really are not up to par with an unmolested GT30 or 35R series turbo.


They DO work, but are laggy as shit and you probably wont be happy.

There are six kits that are available from your link. Which one are you refering to? Keep in mind; The larger the area ratio (A/R), more lag it will have, but better exhaust flow, and more top end power. The smaller the A/R the more restricted the flow, a little sacrifice at top end, but better spool.
What exactly are you going for with your car?
As far as the above manifold? Tubular manifolds have a tendency to crack, especially ones constructed of 304ss. You could take it to a welding shop and have them weld additional support between the flanges which helps a great deal, or hold out for one constructed of 321ss.

i want my car to be like the evo w/ the gt35r thats killing all the cobras. But i want an evo that runs mid to high 10s. I was wondering how much it would cost me to make around 550whp. Like wat turbo kit u guys recommend, what clutch, i already know im getting the 2.3stroker kit. but wat else would i need.

thats not always true, different designed turbine housings with different volute designs will not be easily compaired by a/r. think about it, increasing r changes the ar value, but does it change top end? the restriction has not be decreased, and the only thing that might change is the velocity(component of velocity that is, aka the angle) at which the exhaust gases hit the turbine wheel. a gt3071r will have lower top end than a gt3076r, but not because the a/r is bigger, its because its the same exact turbo, and same turbine design, with a larger a/r.
