First of a big ...

Then, I have a set of injectors that came from a 1st generation 4AGE, they flow 182cc's, which you can have. I don't know how this compares to the VW ones, but they should be close anyway, and you'll have some capacity for when the turbo bug bites...

Then you'll also need to have a fuel rail made up, this can be as simple as a piece of solid aluminium that is hollowed out, and has places machined into it for the back of the injectors to fit into. On that you'll need a fuel pressure regulator, I have one, also from a 4AGE, which you can have. Just remember that you'll nee to have at least 2 bosses in the mani and the rail to bolt the lot down.

For the plenum You simply take a piece of 100mm round aluminium tube, weld an end onto it, and a flange for the throttle onto the other side. This in turn could be welded onto the intake manifold or if you flatten it on one side, simply bolted down. In theory, this is if you plan to go turbo later on, it would be ok to have a plenum made up of square tubing, as the turbulence created will work better for that type of application.

Then from either GW or Volkspares you can get a fuel pump for as little as R399. You can simply use the original pickup from the tank for a start, but you'll have to run high pressure fuel lines to the motor for this application. The original fuel line and one vent on top of the tank can be used for the return. If you plan on going turbo one day, you will might need to install a slightly bigger pickup once you do so.
