Hey
I have to get one for my Turbo Corolla.
After i filled out a modifications booklet, the transport department sent back a letter saying I needed engineering for a few things. Eg, different engine. It also needed a sound and brake test done.
So I rang around for engineers and found one that can do it.
Yes you just get a piece of paper.. cost me $800
Then when I went through the pits I got a modifications permit that had a reference number, that refers too the Certificate. Not to sure if it get into there system but.
First thing I would do is fill out the Modifications Booklet and send it in.. Takes about a month until they send back a letter saying if it needs a engineers certificate.
