PRO-RACE 4cyl DCOE throttle body kit Throttles - Tapered Bore

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 SETUP:

There are two linkage options for this kit.

• Centre Pulley and Joiner Balancer - will only work if your manifold has throttle body mounting bolts that allow your throttle shafts to align perfectly end-to-end without any offset.
• Idler Shaft with Drop Linkages - This is the premium setup and can be used on a kit where the manifold has tilted throttles (to allow carburetor bowls to sit horizontally).

If your manifold allows the throttle shafts to align perfectly end-to-end, then you may choose either the Centre Pulley and Joiner Balancer option, or Idler Shaft with Drop Links option.

If your manifold has tilted throttle body mounting bolts, you must use the Idler Shaft with Drop Links option.

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.
