Pro-Series Lexus V8 quad pro street IDF V8 stack injection kit

HP RATING:

We rate our 50mm V8 Stack and Cross Ram kits at 580HP - 600HP Naturally Aspirated. 

This, of course, does not mean that your engine will make that much power, but so long as the rest of the engine and tuning is up to it, this kit can support up to between 580HP and 600HP.

BOOSTED VS NATURALLY ASPIRATED:

We have lip seals behind the throttle shaft bearings to stop grease from being sucked out of the bearings under high intake runner vacuum. These are turned around on boosted applications so there is no boost leakage and also stops the bearing grease getting evacuated from the throttle shaft the bearings. 

We ask you if you are going to run your engine Boosted, or Naturally Aspirated so we can install the Lip Seals in your throttle bodies in the appropriate way to suit your application.

  LINKAGE AND RAM TUBE COLOURS:

  
  

  Due to overwhelming demand from our customers, we are transitioning our standard colour from Blue to Black.  Black is a classic colour, and goes with pretty much every engine bay colour and style.

  
  

  This includes Ram Tubes, Linkages, Cable Pulleys, Drop Links, Bell Cranks, and more.

  
  

  Don't worry if you love blue, you can still get your kit in blue.  There will be a small premium of $40 per kit to cover us sending out your kit of parts to be anodized blue.  If you would like blue anodizing, please let us know by typing in the notes area of your order.
