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.

    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
    • Yes sir am asking is there possible way from aem tuner from wiring pins 
    • Have you checked cam to crank timing and confirmed balancer marks are correct?
