If you can't borrow one, they are fairly easy to make if you do it right. One of these http://www.bunnings.com.au/holman-15mm-pvc-cap_p3140421 the same size as your turbo outlet and one of these http://pages.ebay.com/link/?nav=item...053300&alt=web or similar and a drill/knife is all you need. Attach valve to pvc cap and tighten well. Take off the first boost hose (from turbo to intercooler), put the PVC inside and tighten clamp, then reattach to the intercooler and pressurise.
How were you doing it before can I ask?
