12HT injector thread diameter - compression tester adaptor (1 Viewer)

[AussieHJCruza]

G'day guys and girls,

Wondering if someone has the thread diameter and pitch of 12HT injectors please - I'm preparing to do a 12HT swap into HJ47 and wanting to do a quick compression test to make sure all is healthy before the 47 gets her new powerplant.

I haven't got the donor HJ61 yet and would like to get the tools I need before it arrives.

Thanks

Do they have a thread? I thought they were held in by 2 bolts. You need a dummy injector that can connect to the compression tester.
Toyota use to sell them but they seem to be out of stock or out of production
They also suit a 13BT

Thanks @roscoFJ73 - just learned something today! I've got a mate with a lathe so might see if he can turn something up for me.

There are some pics of home made adapters on google images. You might be able to sell a few of your mates adaptors. I think Toyota wanted a $100 ea when they had them.
