AMS Performance 1000hp GT-R Build Update

January 23, 2010

The build up of this monster Godzilla is not being rushed in any way. AMS have gained their solid reputation from doing things right and so, in that tradition here’s their progress so far.

Last update we showed you how they used a co-ordinate mapping machine to map the inside of the GT-R engine bay. This was done so they could correctly size the turbo, manifold, wastegate and downpipe configuration to completely maximise the available space. Since then they have spent a lot of time at the CAD software designing how the manifolds will meet all of their design goals like:

  • Completely equal length
  • Port matched
  • Smooth transitions
  • Ease of manifold bolt access
  • Cast in 304 stainless steel

They finished their preliminary design earlier this month and so it was time to move to the fitment testing part of the project. AMS use a plastic composite mock up of the complete part. This is printed in a sophisticated 3D printer by building up layer upon layer of plastic material to slowly build out a exact size replica part within a very tight tolerance.

Once out of the printer they can actually bolt this up to the car to ensure their design matches reality and that it truly will fit into the car. This is the next steps. As you can see in these photos it’s already bolted up to the VR38, next step is to drop the motor in the car and check if the custom heat shields bolt up as planned.

If everything checks out, AMS can organize to have the part cast in stainless steel. Once that is done then they’ll have the moulds for production for other customer cars.
