Aaron’s Red TT

Aaron's red twin-turbo Z32 was a recent acquisition that came in for a plenum pull and associated preventative maintenance, and of course some bling. Aaron got his hands in from start to finish and learnt a lot in the process; something not every workshop can offer.

In the pic below you can see the plenum and valve covers have been removed ready for paint. The plenum will be getting a black powdercoat finish, and the valve covers will be painted in a "Fire Red" metallic.

The injectors were removed for servicing while the plenum was off. They came back nice and clean but unfortunately the rail wasn't reassembled prior to being returned to the owner. I wanted to make sure the injectors were sealing before reassembling the motor, so I made up a simple test rig with an esky and a small compressor. That's Aaron pressurising the rail below.

Fortunately they held pressure without issue.

Below you can see the valve covers back on and the fuel rail reinstalled. The old nissan bolts have been replaced with stainless items and red finish washers from our Z-Spec fastener range. The little details will really add up once it is back together.

Here we are testing for boost/vacuum leaks prior to start up. I'm pretty big on "measure twice"; the five or ten minutes spent double checking everything can save a lot of time trying to find problems down the track.

And last but not least here we are back together. I'm very pleased with the finished result, I'd have to say it is one of the nicest that I've worked on. The full list of jobs performed on this one can be found below.
