about to buy a turbo kit i already know what kind of kit im getting but i cant decide on something. im either going to get a kit with a bottom mount turbo manifold, or one with a top mount turbo manifold.

so my question is, are either one of those manifolds more efficient than the other or would they make about the same power?

both will be basically same full race turbo kit just can't decide if i want the top mount or the bottom mount manifold.

???

im not worried about making enough power, im using a Garret gt3567r turbo, the problem is not whether or not i will make power. its if i used the same setup just with a different manifold, would using one manifold put out higher numbers than using the other, or would both on the same setup put down about the same??

 

Power is not the issue, and you will not benefit additionally from one over the other UNLESS:

1) You are using the car strictly as a drag race application, in which the configuration and additional weight of the manifold and turbo are used to add weight to the front of the car

2)Your intercooler and radiator system have also been configured to match the exhaust manifold / turbo combination.

3) Depending upon the size of the turbocharger.


If this is a "street/strip" purpose, you could be putting the turbo at great risk for foreign object debris, and other road hazards. Even a topmount manifold may not be necessary depending upon the power goals desired.

If you have to ask if you have enough power, you might need to look at the turbocharger setup that you're using, and not just topmount/front mount.
