Jason was on other owner of a Zenki leopard. He was not as active on these forums as his regional forum. This is also one of the few leopards that made its way to Australia
He sent me pictures years ago when he was building a drift leopard. This included stripping the whole interior out and swapping in an SR20DET.
I also think he couldn’t find a replacement rear glass, so he might have attempted plexiglass.
This was years ago, and I haven’t seen or heard about any updates unfortunately.
