Intake Manifold Rb25det

[r33freely]

Just wondering if any one is using a trust or greddy intake manifold and if so why you whent that way and would you recomend it. i know there dear to buy but hopefully have one sorted at the right price. i thaught it would be good because it means less piping and would suit further devolopment of the engine?

Their has been many arguements about this and the standard Plenum.

Basically you don't need an aftermarket Greddy intake plenum inless you are going to be running huge amounts of boost which the standard one will suffer. Flow rate test's have been done and they are the same until higher boost level's, eg: inless your going to be running 25psi + of boost then its not really needed.

Spend you'r money on other things that will actually be worth while eg: A set of Cam's or injectors or a PFC ?

The good things about this Plenum are,

As you mentioned the room factor and less cooler piping, it looks heaps neater and you can access the injector's very easily with having to pull apart everything.

Another thing most people would think that the throttle response would be better becuase of shorter piping etc. You won't get anything noticable, If you do test and so on you may find a couple of ms difference.

At the end of the day as most ppl will tell you, dont waste you'r money as the standard plenum is fine just look at INASNT's car as an eg. Inless you'r going for massive power.
